Q: Solved: How to rebuild RAID 1 array after temporary disconnecting of 1 of drives?

My machine has an SSD boot drive and 2 3TB HDDs for storage. The 3TB drives are (were) in a RAID 1 array (a software array, managed by Win7) to provide a redundant backup. I had a problem w/ the boot drive from another computer, so I temporarily disconnected 1 of the 3TB drives so I could hook up the suspect drive.

I rebooted w/ the suspect drive (which didn't work), shut the computer down, and reconnected the 3TB drive. Now when I go into Disk Management to rebuild/resync the array, all of the options that I think I need to use are grayed out.

So how do I get this back together?? Both drives still have nearly identical data on them, so I thought it would just be a matter of resyncing them.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

I have an EliteDesk 800 G1 running Win 7x64 Ultimate, with a 1TB system drive and a 4x2.7TB (8TB total) RAID-5 array functioning as a library.  The system drive only had about 300 GB of data on it; OS and apps and a little data.The system is set up so it boots from the 1TB 10K 2.5" Velociraptor drive for speed, but all the critical data is safely stored in RAID-5.Three days ago, the 1TB system drive failed.  (I tried mightily to revive it, but I think I can hear something rattling when I shake it gently.) So I bought a new 1TB drive and started to rebuild the system.But I can't get it to see the RAID-5 array as a single drive, and I can't get at the data.  (There's a lot of it, and it's very valuable to me.)When booting, I see the screen go by that gives me the ability to configure the drives (I think it's BIOS-level RAID control, "Press CTRL+I to configure")) and it shows all the drives are present and part of an array, but when I stop it to inquire, I can't do anything but exit or take drives out of the array. How do I get that array to connect to the system again?  RAID-5 was supposed to keep the data safer!

A:RAID-5 array not mounting after system rebuild

 Hi,  Please post the HP product number your PC so that the members of the community can better assist you with your questions and issues. Probably nothing wrong with the RAID array unless the motherboard is bad.  Did you reinstall the RAID drivers in W7 when you rebuilt the system drive? Review the RAID drivers that are available from Intel if you haven't done so.

I have an HP prolaint ML110 sever using Window 2000 server (yes, old). Hard drive is a Raid 1 with 2 disc hard drive. One of the hard drives went "critical". I replaced the bad hard drive and hit Cntrl F to enter the Fastbuild utility by Promise Technology and it only offers 4 options. 1. View array 2. Define array 3. Delete array 4. Configure array. There is no option to 5. Rebuild array.

I looked online at the manual and it shows the 5th option and instructions. Anyone know my version of Fastbuild 1.0 and how to rebuild an array?

My computer presently won't boot by a: or CD ROM. I tried to change the boot menu many times. So, not sure I can install a new utility. Unless a better idea emerges.

I would appreciate any ideas on how to rebuild this hard drive and work with this Raid System.

Thank you

Most controllers will automatically rebuild the array for you automatically. But I don't use Promise controllers so I'm sure if that one should as well.

We're using a DatOptic (SBOX-R) External Disk Array (eSata).
Sil 4726 based.

This box is connected to the HP computer (HP Pavilion Elite d5000t ATX) via a FD 2 Port eSATA PCI-Express Adapter - SATAPCIE2 controller
DatOptic - Sbox-R 5 bay eStata Raid w/PM

The device is reporting that the failed disk was rebuilt to the hotswap drive we have installed.

There were two volumes created on the Raid and the second volume isn't even showing up in Windows Vista (64bit).

The first volume is being reported back to vista as RAW space.

I'm not sure if this is a configuration issue or if we just ended up buying something other then what we though we were buying..

I've searched for a few hours and can't seem to get any more info then what was provided in the .pdf's that came with the steelvine processor management software.

I have a Dell workstation with a 500-GB RAID 1 array, using Intel Matrix Manager and running XP Pro. I want to replace the two physical drives in that array with a pair of 1-GB drives. My current drives have three partitions; I'd like the new drives to have the same content in the same partitions, but to enlarge two of the partitions slightly and make the third partition at least 400 GB.

How do I go about this?

Hi, I'm wondering if anyone can shed light on this issue:

The system has 2x 1Tb drives to create the C: system drive and 2x 3Tb drives to create the D: storage drive (both RAID 0) running Windows 7.

I installed a SSD drive to the computer as well as a hot-swap caddy, but to get enough SATA ports I had to move the 2x 3Tb drives to the caddy.

After this was done, the computer was started up and showed the C: and D: intact, I then used the provided software to install the SSD drive and called it E:

Finally, a fresh install of Windows 7 was put on the SSD.

Now somehow the RAID 0 array was upset. The disk management shows and Unknown drive that adds up to 6Tb, asking me to initialise it. The D: drive does not appear in My Computer. When I run the Intel Disk Management software, I could see another Unknown Disk with 0Gb which is now pairing with one of the 3Tb drives.

The entire system has been put back to the way it started to the best of my knowledge, with all the drives attached to the original SATA ports, the SSD and the other version of Windows removed, but the strange 0Gb drive remains.

Does anyone have any solutions? I have included a screenshot of the drives.
Thanks, Michael

A:Raid 0 Array failure - one of the drives is pairing with an unknown drive

You generally can't move RAID drives around if you wish to keep your data. They should also stay connected to the same SATA ports and in the same order. You may have the ports for the two 3TB drives reversed or on the wrong ports. You may have better luck determining which drive is the problem by using the pre-OS Intel RST RAID utility; it may tell you which drive is not being detected correctly. Also, bypass the hot swap caddies in case they are part of the problem.

I also concerned that you said to get enough ports you had to move the drives to a caddy, this caddy doesn't have it's own controller with a SATA multiplier does it? If so that's a huge mistake.

I hope you are of the significantly higher chance of unrecoverable data loss when running RAID-0.

My system has been running fine for quite some time. I'm running Vista Ultimate on an ASUS P5ND2-SLI mobo.

I just picked up 2 new 500 GB SATA drives to use for data storage, RAID 1 . My OS will remain as is, on a single, non-raid drive.

I hooked up the two SATA drives and followed the instructions from my ASUS user guide:
With the BIOS, I enabled RAID and selected the drives.
With the NVIDIA Raid Utility I set up the RAID array as Mirrored and selected the drives. It seemed to go well.

But Vista does not recognize the two drives as a RAID array. It shows two distinct drives (this was with the Vista Disk Management Util and with Device Manager as well)

I called ASUS and got someone on the phone fairly quickly, although they informed me that I had done everything correctly so this must be a Vista issue. According to the ASUS rep, I do NOT need RAID drivers for Vista because the OS is not installed on the array.

Any ideas. Thanks for any help.

A:Vista doesn't see my additional hard drives as part of a RAID array

I would use the bios utilty to delete the array and re-create it.

Asus rep is wrong me thinks, you do need the raid drivers for the mirror to be seen correctly by the OS.

My mum recently gave her computer to me since she got a netbook and thought that she wasn't getting enough use out of such a computer. An error message kept showing up when I powered on the computer, apparently this had been showing up for some time.
It was on the Intel Matrix Storage Manager before Windows started, one of the physical disks were listed in red. However, the computer was still in full working order, but I wanted to get rid of the screen that kept coming up, so in an attempt to fix it, I went into the Matrix Storage Manager's configuration utility and not knowing what it would do, reset the disk listed in red to Non-Raid.

Now ever since I've done that, I've seen nothing except the BIOS, all that comes up after the Matrix Storage Utility now is a device listing and it says at the bottom 'DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER'. I inserted an OS disk and nothing would come up. Since then, the closest thing I've had to progress was by going into the BIOS settings and changing the hard disks SATA mode to 'IDE'.
After setting it to that, the Matrix Storage Utility doesn't show up, which I thought was a good sign at first, but then afterwards the same final screen shows up, but the message at the bottom had changed.

Hi Everyone,

I have just cloned a RAID array and I am concerned about it's performance.

A bit of background...

My Motherboard = ASUS Z9PE-D16
RAID Card = PIKE 2008 LSISAS RAID card

The initial RAID array consisted of 6 x 1TB Seagate Constellation (ST1000NM001) SAS drives in a RAID1+0 (10) configuration.

The new array consists of 6 x 4TB WD SATA drives in a RAID1+0 (10) configuration.

Initial performance is quite slow, but this may just be due to parity checking. On paper the original, and new drives are comparable.

Whilst the original drives were SAS and the new drives are SATA they both operate at 7200RPM and have 6Gbps interfaces.

My question is - "Is my initial slow performance likely due to parity checking, or will I experience ongoing slowness?"

Any help here will be greatly appreciated. Furthermore whatever you offer with regard to help may assist a piece of Australian Cultural heritage!

Kind Regards,

Background: Problems initially started about 2 months ago when i first started having video issues which seemed to happen when just bumping my desk. Touching or moving my dvi cable returned the display to normal which lead me to believe my cable was going bad. This went on for a couple of weeks and than the display went completely out. Looked in my case and I can see that my liquid cooling system has been leaking onto my video card. The coolant is dried out on the edge of the spills and coagualated in the center. Take it out, cleaned the back of the card removing all the dried and coagulated coolant. What the hell, throw it back in (tightened my clamps first) and see if it works. It does. Monitored it for 2 weeks no leaks, no problems. Sigh of relief. Than display goes fuzzy, still havent replaced cable, but i peek inside the case and its leaking again. Took out the video card, cleaned it, replaced my tubes and connectors, swapped dvi cable from another pc, sorry kids, started it up and BSOD. Started up again and LCD monitor stops with VGA BIOS message. Not sure of next steps, but somewhere I replaced the video card (was running SLI) and cleared the CMOS. Somewhere I think i forget to enable Raid as it the boot up continued to BSOD. I think my drive letters got messed up from clearing the cmos and I may have booted with only 1 drive powered on initially. The Raid message that flashed was it was degraded.

Sorry, I'm not an expert at this.

I have a 3-year old Dell E510 with two 160 gb hard drives, factory installed Raid 1 configuration. I have Windows XP.

For the last week, sometimes both drives come on, sometimes just one comes on and the configuration is Degraded. I can hear one of the drives (always the same one) trying several times to start, then stopping. It then boots pretty normally albeit slowly.

I have a new 250 gb drive still in the box, from the same manufacturer, Western Digital. They told me it replaces the 160.

Can I just pull the bad disk out and put the new one in, then start the computer so that the array rebuilds? Anything else I need to do? I know which disk is bad from the serial number of the normal drive shown at bootup.

Can somebody point me to a post that covers this if I missed it in the forum.

I just switched my EPOX 9NPA+SLI mobo for an ABIT KN8 SLI.Since these both have the Nvidia nForce4 SLI chipset, do I have to use the RAID drivers that came on the ABIT cd or are the RAID drivers that came on the EPOX cd usable? The reason I ask is that with the new mobo installed, at the POST, it shows that I have a healthy striped RAID array. Unfortunately after the POST I get the screen giving me the options of booting into safe mode, safe mode w/ network, last known good config, and so on....It doesn't matter which I choose because whatever i pick, reboots the computer and I end up at the same boot screen options. Vicious circle, to say the least. Anybody have a guess why it isn't booting up even though it shows that my RAID setup is good?

Just looking for a bit of advice. My system is currently running on a 200GB Seagate Barracuda SATA drive - my last IDE drive suffered a failure a few days ago. Unfortunately, it was the one supporting the OS - the SATA was operating as a data drive. I was able to clone the drive and get most of the data off it, but it has taken me two days to get the system running properly again (this was a new experience, and some flailing went on 'till I got it right).

However, my new HD came in - for some reason I thought I'd purchased a 160GB drive, but what's sitting in front of me is identical to what's running in my system. I hadn't considered it before, but suddenly I have the capability of setting up a RAID 0 or RAID 1 array. My mobo's an Asus K7V Deluxe, so it will easily support this.

I've done my reading, and understand that RAID 0 is fast but there's no reduncancy, making it twice as likely to suffer a HD failure... RAID 1 is redundant, but would only give me 200GB, and I need more. I can't really afford a 3rd drive to implement RAID 5 (maybe later...)

My questions are more practical. How hard is it *really* to set up a RAID array? How about when one of the disks is already in service? Can I even do it, without erasing the data that's on the current drive?

Appreciate any insight!

A:Solved: RAID Array questions

You are correct with everything that you say about setting up RAID0 and RAID1. They are both easy to set up especially with the two SATA drives. (Do you have the MB manual?) You will require additional backup if you use RAID0. RAID1 will give you that but as you say you will be limited in your hard drive space. Either way you will lose what's on your present HD.

A:Solved: Expanding RAID 5 Array

Once the array has been rebuilt it shows up as unused space. You can then resize the partition using Paragon or Acronis or create another logical drive in the unused space. I can't remember if diskpart will increase the partition size without reformatting or not.
Some raid controllers don't allow for addition of drives incorporated into the previous partition for some reason. Check here for more info.

Hello, I have a computer that has 4x 300BG hard drives i'm trying to create a RAID 10 system out of.

I have assembled everything in an imgur album here: http://imgur.com/a/U7hAI

I run into a problem (picture #s 9 -->8 -->7, in the order the screens appear as you press enter). The drives as they are connected don't seem to be recognized in the first place? And this means I can't configure RAID 10.

I would really appreciate it if someone could take a look and point out any glaring errors or at least offer some advice to troubleshoot this further. Pictures 1-3 show how the connections are arranged. The hard drives are connected to the RAID controller by a Discrete SATA to SFF-8087 Mini SAS Reverse breakout cable. The disk drive is connected directly to the motherboard. All parts are HP so hardware compatibility is not something i'm considering to be an issue.

Thank you a ton in advance! I'll keep up with replies as soon as possible. If there's any other information necessary I will provide edits of course.

Might as well disable the RAID in the BIOS, test each drive, and use those. The BIOS will have an option to set the SATA controller mode from RAID to AHCI( or to IDE/Legacy mode if using a non-Dell Windows XP disc).

I don't think I would bother with Windows 8 on such an old computer, Windows 7 won't even work that well on it considering it's only a single core Pentium 4. XP is best suited for that system.

Hi, apologies if this has been answered elsewhere couldn't see anything related to this specifically.

This may just be me being stupid, so sorry if that is the case.

My issue is that the RAID does not appear in "My Computer".

Do I need to partition & format the drives before they will appear?
If so, is it easiest to create them using Windows XP install and just abort before format & install?

If its not above... then here's the details:
I have just purchased 2 SATA HDD's and Installed them to an existing computer (with a single hard drive running Windows XP Pro).

I have enabled the SATA ports in the BIOS and enabled the RAID option, having completed this I pressed F10 on boot to access the RAID utility. I have created a RAID array with the 2 drives. On boot the system picks up all 3 Hard-drives and it states the RAID is healthy before booting into Windows. I have installed the RAID controller, drivers that came with my MOBO.

Any help with this matter is greatly appreciated.

Kind Regards,

yes you do need to partition and format. To get to disk management if you dont already know is to click Start, Run, type compmgmt.msc, and its an option in the left hand side.

You must be using a Nvidia Controller for RAID right? The media shield option in your motherboard Nforce driver package is the windows utility for that.

Hi all,
My RAID 1 (I think? I have two equal drives that are mirrored) array was causing me a lot of pain. It kept freezing up my system and having me to had to rebuild the RAID too often. After a number of tests and browsing info online, I've decided that the RAID was the culprit of the freezing and BSODs that came once in a while.

Before deleting the RAID array, I went and used the Seagate (my HDDs) .iso file and used their diagnostic tool to check the drives. I did a long test of one of the HDD (Device 1) and it passed. I deduced that this was at least a good drive. I didn't do a long test for the other HDD (Device 0). But with both, after a short test, both passed.

I then went into the RAID manager (DOS-looking screen before Windows starts) and then 'reverted' Device 1 to non-raid. Then decided to choose 'delete RAID setup' for the Device 0. All good so far. I rebooted and Windows actually started fine. This is where I'm at right now as I type this. No freezing so far!!!

What I wanted to know is how do I find out which HDD Windows is booting off from? Is there a command line I can use in command prompt window in DOS mode to find out this info? It'd be great to know that I'm not on Device 0 since I haven't done a Seagate diagnostic long test on that one.

Also, I'd ideally want to have the second (Device 0) HDD formatted so that I can leave it in my tower and use it as an external HDD with Syncback. This is the closest thing I can have to RAID and I'm perfectly happy ... Read more

A:RAID - deleted RAID array, Windows 7 ok but I have questions

You can do into Disk Management and it will tell you which drive is used for booting. It will say it is active.

I am confused as to one part. You say you want to leave the second drive in your computer, but use it as an external. You can use one as your main drive, and use the other for backup...however a good backup process involves a drive that isn't readily available all the time. That being said, something like SyncToy from Microsoft will allow you to choose folders and on a schedule or manually, copy them to the second drive. I use this on my wife's laptop to keep her photos backed up to our server.

RAID has no place on a desktop system, so you are better off without it. But to get started, just go into Disk Management to see how your drives are configured now. Post a screenshot if need be.

hello everyone,

I am thinking to renew the whole data in current raid1 array md0. My environment is:

raiddev /dev/md0
raid-level 1
persistent-superblock 0
chunk-size 16
nr-raid-disks 2
nr-spare-disks 0
device /dev/hdb1
raid-disk 0
device /dev/hdd1
raid-disk 1

this '/dev/md0' is /home, so I'm not booting from this disk and the other file systems including root and /boot are on /dev/hda.

What I want to do is to renew the whole data in /home.

Is there any way to do this by switching /dev/hdd1 with all new data copied, then sync this new data to the other raid disk (/dev/hdb1) : FROM /dev/hdd1 (the disk just added with new data) TO /dev/hdb1 (currently active raid disk)??

Usually, after switching the HDD to new one, data in /dev/hdb1 is to be copied to /dev/hdd1 for recovery. But in my case, I want to do the opposite.

I would be so appreciated by all your helps,
Thank you,

A:RAID question: how can I renew the data in raid array?

I'm not sure what you want to do.. You want to copy something to the /dev/hdd disk (from another computer maybe) and then copy the data from /dev/hdd to the RAID array?

Since you are using RAID1 then it should be fairly simple.
You just simulate disk failure by removing /dev/hdd. You could do this by making the hdd drive hdc instead (jumper it to be the secondary master). Now you mount the "hdc" drive (that really was you hdd) and copy whatever you want to /dev/md0.
Since it's a RAID1 array then all the data that goes to md0 is written to hdb and when the /dev/hdd comes back the RAID is syned onto both disks again.

I'm not sure if that makes any sense to you. Can't be less obscure than your post though

Hi, I have a card reader with 4 slots which equate to 4 temporary drives when the card reader is plugged in. However for quite some time now, the 4 drives (G,H,I & J) remain in the Menu even when the device isn't plugged in. If I do plug the device in the 4 drives G,H I & J remain inactive and another 4 drives are made K, L, M & N.

If I try to "Safely Remove Hardware" I get a message saying "Windows can't stop your 'Generic- MS/MS-Pro USB Device' because a program is still using it (blah blah blah), despite absolutely nothing being open besides the Desktop.

Also if I access the properties the drive it says that the drive is used 100% but at 0bytes and if I left click it, it asks me to insert a disk.

How do I get rid of these "drives"?

It's not causing any problems as such, it's just an irritation!

I've included some captured shots.

A few days after initial installation, I had a single drive error with my RAID 5 config. I am running three WD 500GB HDs in a RAID 5, with no other internal drives. I verified the questionable drive with slow scans. I used my Intel BIOS to add the drive back into my RAID. So far everything looked great.

But, my BIOS shows all three drives in a good RAID 5 with a status of "Rebuild." There is also a comment on the BIOS screen that "RAID 5 will be rebuilt within the operating system." I looked in W7 for rebuild opportunities, but I did not finding any. So I assumed that the rebuild would be an automatic/background rebuild. I have had my system on for 1 week with no joy. BIOS status still shows "rebuild."

My question is: Am I OK? The Computer Management shows a single healthy partition at full allocation (1,031GB, with "no" Fault Tolerance)? How do you rebuild a RAID 5 with W7?

A:How to rebuild RAID 5 within W7


I believe there is an option to do this using the DISKPART command (run that from an elevated CMD window). I have never used it, so unfortunately I can't help with the details of the command.

Let us know how you get on with it.

I have an ASUS M4A79XTD EVO board which had 2 drives setup in RAID1, I replaced one of the drives after a failure but can't seem to rebuild the RAID. The raid software shows one drive as RAID LD-1 and the other as a single drive, both drives are 320GB SATA drives from western digital. I can't seem to find a way of rebuilding the RAID.
If I delete the existing RAID and setup a new one will I lose all the data on the original RAID disc?

Hi ,

RAID and Win 7 Home Premium newbie. Short version of long story - replaced old dead RAID Drives in Win XP system with (2) new 500GB Drives plus plan to upgrade RAM to 8GB (would have liked more but $$$) and install new OS = WIN 7 Home Premium 64 Bit.

MB is GA-EP45-UD3R Rev 1.1 and I am having trouble figuring out how to get, prepare and install the Intel RAID Drivers for 64 Bit Win 7 HP.

My main problem is that on the Gigabyte site they offer two RAID Drives.

Intel SATA Preinstall driver (For AHCI / RAID Mode) Note: Press F6 during Windows setup to read from floppy. OS: Windows XP 64bit,Windows Server 2003 64bit 0.32 MB 2009/08/11

The first "pre-install" driver extract to a 64Bit (bootdisk - Win XP 64?) and the second "I do not know when to use it" Driver extracts to a (iata_cd.exe).

This is where I am totally lost. Which RAID Driver and from where do I install during the clean install of Win 7.

I get the need for a USB Stick/Thumb Drive with the RAID Driver on it that Win 7 will ask to be pointed at, but which Driver????

A:New RAID Array and Clean Install Win7HP-Help with RAID Driver Install

The pre-install driver will allow setup to install the files correcty on the RAID array this is offered for XP only.

When you have created the RAID array in the BIOS Utility and you launch the windows 7 setup does it show the new array as a possible install location? If so there is no need for a pre-install driver (Win7 supports a variety of RAID setup out of the box).

If you do need a pre-install driver, you have not been offered one for Win7/Vista on the Manufacturers website. The only solution to this I have found is to Download "7lite/Nlite" and build the "post install" driver into the win7 image then burn a new disk (or burn to USB pen for faster install).

Hope this helps.

Alright heres my problem, I recently killed my motherboard(Epox 8k3a+) during a recapping procedure and I was using the onboard RAID controller with 2 80GB Seagate drive setup in RAID 0. My Question is can I just purchase another motherboard with an identical RAID controller on it (Highpoint HPT372) and I should be able to boot it up off my drives? Anyone done something like this before? Even getting into safemode would work. Ive tried to use RAID Rebuilder and GetDataBack from Runtime Software and there are many files that dont get found and it acts as if the drives are bad but I know they arent. I am unable to get another 8k3a+ but I can get a 8k9a2+ which has the same RAID on it just a different chipset(KT400 from KT333ce). I really need some help to get the data off these drives.

A:Rebuild RAID setup

It should Just Work if you set the drives to RAID0 with the right stripe size setting. Don't initialize the array!

It may be better to use Linux software RAID to get the data - it's free and it is easier to play around with settings and such. Needs Linux and RAID expertise though..

Hello All,
I faced the same problem as georgiaredhead20 stated on Jan 2010.

I have a raid 5 system using Silicon Image Si3124 and four 320GB HDD.
One drive was reported orphan (the other three reported good by the SATARAID Manager software).
The raid 5 was offline and the Windows XP cannot see it.
(Usually a raid 5 should keep working when 1-out-of-4 drive is faulty).

I replaced the orphan drive with a new 320GB HDD but the option for "REBUILD" was not available from the option list. (The new HDD was listed as "Pass-through").

I tried to change the new HDD into "GLOBAL SPARE", the "REBUILD" option still not available.
When I tried to change the new HDD into "DEDICATED SPARE" and dedicated to Raid Group 0 (the original raid was designated as RG0), the SATARAID Manager reported that the raid group is not valid.

I would very much appreciate your help.

I also wonder whether georgiaredhead20 already resolved his previous problem.

I am having a problem with setting up a Raid 1 array. I am using Windows Vista Ultimate 32 along with an Asus M2NPV-VM motherboard. After viewing videos on Raid Array setup on Youtube, I decided this chore should not be so difficult. I entered the bios and followed the prompts and made my Raid 1 array. No error messages, and both of my WD3200 HDD were listed, and the array was boot enabled and labeled healthy.
I then inserted my Windows Vista Ultimate CD and clicked on Repair, and on to restore my pc. Windows discovered my external backup, and I then chose the backup that I wanted. I followed the prompts and then clicked restore and received a message that stated that there were to few drives or not enough space to continue. I now do not know how to proceed. Any suggestions would be helpful.
I call this PC my "learning PC". I am trying to learn some of the more exotic functions of my PC. I have read that the Windows Vista built in backup utility is good for backup restore, but not to be used for Raid. Is this true? If so, what product would help me with this issue? Thanks in advance for any suggestions.

Hello. I am new in installing SATA HDD so i am confused when i installed the drive for the first time the nvidia raid bios setup asked me what type am i going to use on the HDD so i selekted the first one that was working (striping). Now my question is: did i selected the proper type ? because i saw that there is other like mirroring and stripe mirroring. If a made a mistake how can i fix it.

A:Raid array

It depends what you want to do. Without getting into a discussion about the value of RAID on a home system in general stripe is what you want. Do some reading here. RAID0 is stripe and RAID1 is mirror.

Just make sure you do back ups of your data to another storage source.

My dad wants a new PC built - he wants a half-decent one, he only surfs web , music and streaming videos - he plays Flight Simulator X but thats all...

his current setup is:
3Ghz Pentium 4 with HT
1Gb Ram
160Gb SATA-II / 8Mb cache
nVidia 6200GS / 256Mb / 300Mhz
Windows XP SP3

now where thinking
Core2Duo (or quad if cheap enough)
2Gb Ram
2 x 160Gb SATA-II drives in RAID array
better nVidia graphics card
Windows 7

my question is this: WHICH IS BEST RAID ARRAY TO USE?

the reason we decided to use these method is for extra performance - now im aware that RAID '0' stripes the data so if 1 drive were to fail then he would have to re-place it or re-install windows on single drive - but you get the most free space and best performance from this...

what about MIRRORING? as he doesnt use much space anyway would he be best with this option? DO YOU STILL GET THE SAME PERFORMANCE FROM MIRRIRON AS YOU DO WITH STRIPING? (except you get less space but if one drive fails everything will still run off other drive....)

his disk usage would only be about 40Gb (without mirroring)

if you DO get the same performance with mirroring then how much space would he get from 2 x 160Gb...? (and installs obviously use double)

would he still get 320Gb with the 40% performance increase from raid'ing two drives together - just installs are double? (thats fine in that case he would only use 80Gb of the 320Gb which leaves him AMPLE)

The Intel Matrix Storage manager does not support adding an additional drive to the array. I have 3 160's now and want to add the 4th. I can set the drive up as a spare only. Is there any other way I can add the 4th drive to it without starting all over and having to install all again. If I have to I will set it up with both a raid 0 and a raid 5 to have the best of both worlds but if I can get the array to take the 4th and migrate whatever then I will leave it with just the raid 5 setup.

Well this morning my 1tb drive seemed to have failed. i got home and was, surprisingly, able to access it again (so im backing everything up off of it now) im thinking, once i get this replaced, of buying another drive and setting them up as RAID 1. do raid 1 drives have to be the exact same model, or just the same capacity? i currently have a St31000340AS which i cant find in stores, only online. would adding a ST310005N1A1AS-RK still allow me to set up a raid 1 array?

thanks for the help
edit - also, how would setting up a raid 5 array work? once again, would i need 3 of the same drives? if not, would having two 1tb drives (not exact same model) and a 200 gig drive work? if so, how? i know it limits the capacity by the size of one disk. which disk would it the extra capacity be removed (like would it end up being a 1tb + 1tb or a 1tb +200g?) also, for each way, do i need any special cables or hardware for each one? my mobo is the Asus A8N-E which i looked up on and it says it supports raid 0/1, but im not sure how support for raid 5 works, if mine even supports it. how would i check or know?

Most cards that support RAID1 will allow you to use two hard drives that are not identical. The smaller of the two capacities will be the size of your RAID1.
ie: Drive 1 = 998GB and Drive 2 is 1TB, the RAID1 size will be 998GB

Setting up a mirror RAID Config should mirror to the second disk. You should not lose any data, Set it up as a broken array, and let it "rebuild". (approx time to rebuild 1TB is 12 hours)

I am getting ready to set up a RAID Array but this is my first time doing anything with RAID. I know how to get into the BIOS and change settings and I know with two hard drives, I should do RAID 1. However, I just have a few questions before I do this. First off, I am an idiot and did not notice that my first hard drive I got when I built the computer has a 32 MB Cache:

Caviar Blue 1TB 7,200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive WD10EALX - OEM

I noticed it only had a 32 MB CACHE when I went to get another one. I then asked for the version with a 64 MB CACHE (WD1002FAEX), paid for it and left. Will these two hard drives work together in RAID if they have different sized caches? Please give me any info/experience you may have with this or anything with RAID would be helpful, thanks.

A:Help w/ RAID Array

The short answer is yes, they'll work. Onboard cache is internal to the drive, and as long as the drives are the same size, then RAID 1 (mirror) should work fine. I don't think it would make much difference, but the drive with the larger cache should be the primary drive just for efficiency's sake.

When I bought my PC 7 years ago, I asked the techs to create a Raid 0 array with my 2 200GB WD drives. Recently, I have been reading the comments here and on other forums to stay away from Raid arrays as they are more problems then they are worth.

What I want to know is what is the best way, and procedure to accomplish this, to remove this Raid 0 array and use my 2 200GB SATA drives as separate drives with the OS on one and data on the other. I will probably partition the OS one as I do not need 200GB for Windows 7.

Am I correct in assuming that once this RAID 0 array is broken, I will lose everything and will have to do a clean install of Windows 7 plus all my apps?

Backup all of your data, make sure that you have backed up all of your data. Remove the array configuration, get out your Windows DVD, reinstall the OS, patches, and all applications, copy your data back from your backup.

I just made a 2-drive raid array on my kid's computer like this:

Iwill KK266 motherboard with 1.4 ghz Athlon, 256 PC133 ram.
Promise Fasttrak66 raid controller
Two IBM 8.4 gb ata33 drives, each a master on its own channel.

I fired it up, and made a raid 0 array with the two drives, 16 gb total, 64 kb stripe.

Ran the Windows XP Pro install CD, and created two partitions on the array of about 8 gb each, and installed WinXp on the first one, formatting it with NTFS. It took a LONG time to format (well over an hour)

Once the Windows desktop was running, I installed a few more programs. The ATTO disk benchmark showed transfer speeds in the 17000 range for the C: drive, so I thought all was well.

But then I noticed I only had less than 700 mb free on the drive! I checked the size of what was installed, and found it to be just over 1300 mb, giving a total of just under 2 gb. These figures are shown on the drive properties screen.

Next I fired up the Disk Manager in the Administrative tools, and it showed both partitions in their correct size of 8 gb. No clue why I was only apparently accessing 2 gb of the C drive.

I then tried formatting the D drive, but after another long process, the format failed. No reason given.

What's going on?? I seem to recall there was some sort of 2 gb partition limit in FAT, but I'm using NTFS.

Can anyone shed some light on this? Am I missing something obvious?

I run an Sil3132r5 with 4 WDC 500G hard drives, 1 drive recently had issues apparently it had "dirty data" per the event log on the sataraid5 app that came with my controller. So i stopped my auto-defragger long enough to try and let it rebuild...still kept failing and aborting. Finally the drive was orphaned somehow (maybe to many power up/downs) so i tried to rebuild it only to find it showing up as a "spare". I then deleted the "spare" and started the rebuild manually again. The rebuild took about 8hours (the disk was pretty full) but then i started noticing the rebuilt volume appeared to be missing data! Strange thing was the percentage of free space was about the same...then i discovered i could even browse to the "invisible" directories by typing in the name(s) as long as i could remember the exact spellings. How can i un-hide all my data (for lack of a better term). Heck, i can even open files if i type in the full address in the address bar...running winXP by the way. Help. I need access to all my data again...and i don't know the names of all my files so that's a pretty bad work around. To add, i keep seeing a yellow triangular alert icon down in the taskbar/system tray, and it seems to pop up every time i see an entry in my sataraid5 app event log for "Database initialized. ."

Hello to all,

I have Dell workstation T5500 in which two SATA HDDs 500 GB are configured as RAID 1 volume. Configuration is performed during POST (Ctrl+I) with Intel Storage ROM.
In order to test something, I have removed one drive (from SATA1) from this station (which stayed OFF until the drive is returned back) and used this drive in another identical machine just to see if the system will boot and it did. Later, when I returned this HDD back to the first Workstation, I have noticed that now HDD in SATA 0 (which wasn't touched) is reported as Offline member. I tried to replug the SATA connectors but that didn't solve the problem.
Then I removed SATA 1 again and turned ON the computer and it booted normally. So I guess I need somehow to rebuild the RAID but need to pay attention not to lose the data. So I have determined that computer is bootable from both drives.

There is no Intel Rapid software installed in windows, so only configuration is done during POST.

How to approach here in order to make RAID 1 fully functional again?
