Windows software RAID 5 reads as RAW, duplicate RAW RAID shows with different drive letter?

Q: Windows software RAID 5 reads as RAW, duplicate RAW RAID shows with different drive letter?

Hi there
Yesterday my computer was shut down when I returned home. I may have lost power but I am connected to a UPS that should have kept me safe from any surges. Turning the computer on, my RAID5 drive (drive letter M) is gone and a mysterious new drive
has appeared, labeled as drive E, also showing as a RAW drive. In disk management, I can see that drive M is its normal size, 11177.94GB. I am using 4x4TB drives. Intel Rapid Storage Technologhe shows all four
drives as healthy and functional. Drive E shows in Disk Management the same as Drive M, and I have no idea how it ended up there and what I should do with it. My C drive shows up and works normally, where I have my OS and programs installed.
Not sure where to start, but hoping it is just an issue with the MBR?

Preferred Solution: Windows software RAID 5 reads as RAW, duplicate RAW RAID shows with different drive letter?

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.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I have a dual Raid 1 configuration with (2) identical 500GB (C and 1TB (D drives. When connecting my (2) external hard drives, one of which needs to be named (F (I have numerous files, folders, icons and programs linked to it), I see that (E and (F are the only two drive letters unavailable for use - presumably because they have been allocated as the invisible/dynamic? drives for (C and (D, respectively. How do I know which one's RAID Mirror is? And can I just rename that drive so the letter becomes available without interrupting/changing/affecting the RAID configuration? Thanks in advance for anyone that can offer insight.

I am running 7 pro 64bit on a ASUS p8p67 deluxe mobo and I copied all data from my 1tb storage D: drive to a backup external and proceded to install raid 5 with 3 single 1tb drives and the raid is up an running. However using Intel Rapid Storage Technology to setup the raid inside windows I had to use the drive letter R: because D: was not available in the list option. When I start some programs, the program is looking for the data on D: drive. Is there any way to change the letter of my raid storage from R: to D:?

A:RAID 5 switched from single storage to raid 5, lost drive letter

It's possible the cd-rom/dvd drive assigned itself as d: before the new raid was created.
This should be solvable using the windows disk management tool if that's the case.

I replaced my 2 aging 250GB drives in my RAID mirror with newer ones. The problem now is that even after formatting one of the old drives for a new OS, is still boots as if it is connected to the Intel RAID mananger, showing that the RAID is degraded and this is on a different computer. How do I remove the RAID info from the drive?

hi, I want to buy two new HDD for my RAID 1 (mirror) in desktop to store my data. i have onboard RAID (ASrock H77M) but also contemplate to use the windows raid on other SATa ports (in case I want two Raid-1). size would be 3 TB or so. this is to keep data until i backup or for the backup (mirroring gives me some added safety)

I want Hitachi for the better reliability (I have WD and happy with them, but it seems Hitachis is a tad better). also want 7200 rpm.

I noticed newegg mainly sells the NAS version of the Deskstar. I read all about the 7-second timeout for NAS drives and how a RAId would drop a normal desktop HDD etc. so normally for a desktop i woudl buy the non-NAS version (which are barely available).

On the other hand the RAId 1 (on-board and windows) may benefit from the NAS version? Or am I overthinking this for RAID 1? Is the NAS version slower? Price-wise it seems more to depend on where to buy them. I don't mind spending $10 or $20 more for the right HDD while i weigh reliability higher than speed.

Currently I have two 750 GB WD Black Caviar in RAID 1 and a WD green as backup (which is terribly slow... never buy a green drive!). My OS (w7 Pro 64) is on a Samsung SSD. So speed is secondary, but I do weekly virsuscan of all my data etc, and noticed the Green drive takes half a day.So i definitely don't want a slow HDD. My case has front fans for the HDD.

A:NAS or desktop HDD for RAID 1 (or windows software raid)

Hey there HerrKaLeun!

I can see you're a bit confused about the drives and NAS requirements. But it's a good thing you're looking into details to understand better. Let me see if I can help you clear things a bit.

The NAS environments are very tough. Regular drives used in RAID/NAS systems can get damaged, destroyed and corrupted really fast because they aren't designed with the "defences" that NAS/RAID hard drives have.

NAS/RAID drives are equipped with technology protecting them from the higher temperatures and constant vibrations, gives them 24/7 reliability, they're tested for longer hours to endure in a harsher environment, all to protect the information you store better.

Some NAS/RAID drives are for smaller NAS systems like the WD Red, others are for larger NAS systems like the WD Red Pro and for large enterprise systems like the WD RE. The "smaller system" drives can't handle larger NASes than the ones they're designed for (e.g. 2-4 bay system is a small NAS), but the "larger system" drives can handle small NASes (e.g. 6-8 bay system is a large NAS); in most cases enterprise NAS/RAID drives are the ones with bigger and safer works.

These reasons are why you should consider a specialized drive for NAS and RAID rather than an usual desktop drive.

The MTBF means Mean Time Between Failure, and is typical to be characterized for such NAS/RAID drives, usually in hours which usually sum up at around 1 mil.

Whether you'll choose a WD, ... Read more

Planning on a new build with storage as follows:

1 - 320G SATA drive partitioned for XP + various apps

2 - 320G SATA in RAID 0 for gaming

1 - 500G SATA for b/u

will be using a P5N32-E SLI 680i board and XP Pro.

I am considering a larger #1 drive with a partition in case I decide to try Vista.

I'm confused as to the physical procedure for setting this up. IF I install all the drives in the system and start to configure, will I run into drive letter issues while setting up the RAID? I'm thinking the 1st physical drive w/b C & D, the RAID 0 will be E and the b/u will be F.

I've set up multiple drives before but not with a RAID array involved.

Any help will be appreciated.

I'd appreciate some help. I'm setting up 2 x Western Digital RE4?s in RAID 1 for Data Storage in a Win 7 Ultimate 64 bit system that is using a single SSD for the OS.


The two RE4?s have been set up in the option ROM and when the OS completes startup, Rapid Storage Technology indicates that the drives were set up correctly in RAID 1.

The drives have been initialized. However, the RAID Volume is not being seen by the OS.
Here?s what I?ve tried: I right-click on ?Computer?, left-click on ?Manage? which takes me into Computer Management. I then left-click on disk management which provides a graphic on the right side of the screen of the unallocated RAID volume. Right-clicking on the unallocated graphic provides the choice of: ?New Simple Volume?, ?New Spanned Volume?, ?New Striped Volume?, ?New Mirrored Volume?, ?Properties?, and ?Help?. Note: ?Change drive letter and path? is NOT available as an option.
From there, I?m not sure how to proceed. The graphical representation of the unallocated volume is the RAID Array. I don?t want to create another RAID 1 Volume.
Any help is appreciated.

Thanks,

My raid 0 drive(s) will not retain their drive letter after reboot. I have to manually set it every time I start the PC.

Initially I "accidentally" set the raid partition to active (overactive clicking while not watching the screen), then thinking it did not really matter just went ahead and set the drive letter to "E" which is the default, and first available entry after a and b. Upon reboot it did it again, lost the drive letter.

I then proceeded to go into the command prompt, and set the drive back to "inactive" which removed the active flag on it. No big deal, easy enough. I reset the drive letter. Then, thinking this might work somehow I rebooted again. Same problem, lost the letter.

I tried a different letter, thinking it could possibly be some registry issue or something, which is very well might be, on the grounds that a different letter might force a new entry? Idk, not all that hot with the registry.

Reboot, same problem.

So now what? I want to back everything up to my primary drives and then reinstall the OS using the raid drives as the system drive. But if this is going to happen again in that case that would be less than ideal.
Anyone?

I have been doing research on purchasing 4-bay+ external RAID enclosure for myself. I have done research on software vs. hardware raids for this system, but one question still eludes me; so I am going to ask it here directly.

If I buy software RAID enclosure I will have to use some included software to set-up my raid. So, if I take my enclosure to another PC and plug it in (let's say eSATA) I will not be able to read the data, correct? If I get true hardware raid, the raid set up will be on the build in controller so I will be able to take the enclosure from computer to computer, right?

And since TS has new poll feature lets try it out...
 

A:Hardware vs. software RAID on 4-bay+ RAID enclosure

Regardless of whether you use software or hardware RAID, the enclosure will work whatever you plug it into. The only thing that might not work is connecting an individual disk (used as part of the array) into a device. It all depends on whether the device in question can read the controller used for the RAID set up.

For example, I ran with RAID 1 for two 2TB hard drives in my PC, but I can connect one of them to the same device as a non-RAID disk -- which I successfully did when the RAID broke down for an unexplained reason.

However, it is unlikely to work in a computer, and you should approach it as not working at all in anything but the RAID enclosure. It's also worth pointing out that splitting RAID disks in such a way could corrupt the data. Given that pretty much every decent RAID enclosure worth its salt will include gigabit ethernet at the size you're looking for, availability shouldn't be an issue across your LAN.

Hardware-based RAID arrays are also more reliable in operation, and have the extra benefit of being recoverable in a controller failure by replacing it with the same version as before. Software RAID's are less reliable, slower performing and in the event of a controller failure can be difficult to bring back online.

Basically, when it comes to RAID arrays, don't skimp on cost. The better the quality/controllers the more reliable and better performing it will be.

First time posting :blush:,

Situation: I have two hard drives : main drive: Seagate 500GB w/ windows xp and second drive: WD 1TB blank.

Without backing up the main drive (ops...), i went ahead and enabled RAID 0 on both drives and created a RAID volume (128KB strip / Size: 1TB (931.5GB)).
NOTE: the RAID volume size is only showing the exact space of the 1TB, excluding the 500GB drive.
After realizing that I needed to create a backup image of my main drive to use RAID with an existing drive, I'm left with the "Operating System Not Found" message.

Question: If I Delete RAID Volume (which is based on the size from the blank 1TB drive), will both drives become available as non-RAID disks and keep the original data on the 500GB main drive and be able to run windows again?

I'm using software RAID through Intel Matrix Storage Manager option ROM v5.6.2

I understood that "Resetting the drives to Non-Raid" will cause all data on the disk to be lost, so this isn't the approach that I'll be taking til I find a solution to backup my data.
However, from reading the "Delete RAID Volume" option, it listed Deleting a volume will destroy the volume data on the drive(s) and cause any member disks to become available as non-RAID disks, so knowing that the RAID Volume is blank, then maybe trying this will be the answer.

A:RAID issue - deleting RAID volume to restore non-RAID disks

sadly, there's no way to do what you want without an existing backup.

Look at it this way;
A disk has a container ~ the partition.
The partition as a structure ~ the filesystem (eg NTFS, FAT32, RAID).
We put our data into the structure.

When we create backups, we are getting only the data itself (unless you use an image program like Ghost or Acronis where you get all three).

Deleting the RAID will give back the two independent HDs, but also breaks the structure so that the data becomes in accessible.

I currently have 4 250gb HDD's and i am going to RAID them through RAID 0, although i am not sure whether i should use a RAID controller, or RAID them using the software in BIOS. I have found a RAID controller for $38 at my local tech store, it supports up to 4 SATA 2 (3gb/s) ports, which is what i need. Although, i am hesitant as to which would be faster, this RAID controller, or setting up RAID 0 through BIOS?

Thank you.
 

A:Hardware RAID vs Software RAID?

A $38 RAID card is likely no better, possibly even worse than the RAID offered by the motherboard, which would be considered firmware RAID, which at $38 the card is probably the same. A true high performance hardware RAID controller will cost hundreds of dollars.

But without exact model numbers it's hard to give a firm answer.

I think I know why it's causing the drive to appear as Non-RAID. My computer restarted itself while I was sleeping. I logged back in and there wasn't any notification from the Intel Matrix Storage Console that my RAID had crashed or was crashing.
I started unzipping a file I just downloaded, and realized something wasn't right since it was taking forever for the file to unzip. I wasn't sure what was going on, so I restarted my computer. That's when during boot it said that one of the drives is a Non-RAID drive. I don't know how to fix it right now, and I would like to refrain from having to re-make the RAID without being able to backup everything from it. Is there some way I can gain access to the HDD that's Non-RAID and delete the files I unzipped to restore it?

You may be able to make #6 be a hotspare without worrying about the array but I think if you want a total of 6 drive raid 5 with no hotspare you will have to rebuild it. Don't quote me on it but I am reasonably sure this is the case.

Usually on servers there are 2 ways to access the raid configuration 1) usually there is a raid utility that is loaded after the OS or 2) the other way is on bootup when it initializes the array you can hit some key combination to get into the array at the pre OS level.

I created a windows system image with the backup and restore utility built into win7. This windows install is on a single hard drive. I built and onboard RAID 0+1 array and used the windows 7 install disk to restore the image on to the new RAID volume. Windows starts to boot up but the screen goes black and reboots. The windows recovery screen appears and asks if I want to run the startup repair or start windows normally. I selected the startup repair. Windows goes through it's paces and tries to repair but fails. It says "NoRootCause" and the problem is likely caused by a recent system change or upgrade. I have the feeling windows needs some kind of RAID drivers or something. The onboard RAID is a P5W DH Deluxe motherboard. Any ideas? Is this even possible to do?

A:Windows 7 System Image - Restore Non-RAID to RAID 0+1

MetalliMyers, welcome to the Seven Forums.

Assuming you built the RAID while still using the single disk this is what worked for me when I was experimenting with RAID,

1. Install drives and configure the array

2. Boot to Windows and install the necessary RAID driver

3. Make a full backup after the drivers are installed

4. Used imaging program (at the time I used Acronis True Home, but should work with any imaging app) to put the backup on the array

5. Disconnected the single drive after imaging just to remove it from causing any problems

6. Started up and it booted to Windows

No promises but it should work. Failing that you are looking at a fresh install of Windows.

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!

I have a MSI K8N Neo2 Nforce3 mobo. It has 4 SATA ports on it.

Right now I have 2 SATA Western Digital 40gig HD's on SATA 1 and 2 ports in a RAID-0 configuration.

I want more disk space so I just purchased a SATA Seagate Barracuda 72000.10 320gig HD. Can I just plug it into SATA port 3 and run with it? I don't want it on the RAID. I just want it as a HD to put pictures and crap that don't need to be on the RAID. I mostly want to use the RAID for games and my OS.

I built a new computer. I wanted it to be more reliable. So, I got two identical hard drives. I installed Win 7 Pro as one big C: partition. Then I converted to dynamic disks and mirrored the first disk onto the second disk. Everything works! I even gave it a test. I powered off, and disconnected the SATA cable on the first hard disk. Windows booted right up, off the second HD. Great! It seems the mirroring works and can tolerate a missing disk. (I had to rebuild the mirror after doing this test.)

I have some questions about how this will work over the long term. I noticed that when the first hard drive was missing from the mirror Windows never gave an error message. How would I detect a failing or failed hard drive? This is important, I think.

How does Windows deal with a bad read on one hard drive in a two drive mirror? Say if one disk reads correctly, but the second disk reads a bad sector, how does Windows know what is the correct data?

I found that Windows gives a text mode menu when I first boot up the computer. It wants me to select which Windows I will boot: the first hard drive or the second "Plex". Is there a way to set a default, so it will always boot the first instance of Windows without user intervention? Or would this defeat the mirroring function in the case of a bad hard drive?

Does anyone have any other wisdom on running software RAID mirror under Windows? Thanks for replies.

A:How to use an manage a Win7 software RAID mirror drive

My suggestion is to not use it at all. RAID is not a backup, so in a mirror, if one file is deleted, or a virus is present...it will affect both. A better method is to run one drive, and use the second in an external cage to keep as a backup. You can use something like SyncToy to keep your important files backed up, once a week or so.

Setup a new RAID. Previously had 10 -80 gig drives, have upgraded to 300gig drives. Using Win2k server. Have about 18-300 gig drives setup in a software raid 5 configuration. 12 drives are in an external enclosures that are connected to USB2.

Here's the thing. Since some of the drives are external, the driver doesn't load for them until after windows reboots. On my last raid, I was able to just simply go into Disk Management, right click, and reactivate those disks, and everything was fine.

Now, with this RAID, (fresh OS, blank from data, I didn't migrate anything, I started fresh with new drives), everytime I reboot, I go into disk management, and reactivate the disk, and after it reactivates, it starts to regenerate. With an array this size, it takes about 3 solid days to regenerate. After it regenerates, everything is fine. All the data is still there, and it's perfectly usable, until I reboot again, and then I have wait another 3 days.

My question is this, how can I make it so I don't have to regenerate the entire array everytime the system is rebooted? The previous raid was setup exactly the same way as this one, except this one has larger drives and more of them.

Any and all help and advise is appreciated. Thank you very much.

A:Windows XP software raid?

Right-click on My Computer and select "Manage" or open the Computer Management console. In the left panel, choose "Disk Management" under "Storage." You will then see the disk manager on the right, and from there you can create dynamic striped partitions.

http://support.microsoft.com/default...b;en-us;308424 - This Microsoft KB article describes dynamic volumes and how to create and configure them. It doesn't talk about RAID 0 much, but just select "striped partition" when you have the option, and the rest of the HOW-TO should apply fine.

NOTE: I am not positive of this, but if you have Windows XP Home Edition, you probably cannot create striped volumes.

I am running Windows 7 Professional 64-bit. I have a single 500GB hard drive, which contains 2 partitions. The first partition is about 265MB and contains Windows 7.

Simon you do realize the speed penalty of RAID 1 vs raid 0 correct? also Raid offers minimal extra data security if any. If your controller dies you lose data, If one drives dies and it is writing to the other at the same time you loose data, etc.

There are other methods that dont involve the performance hit and give you data security

Hello to all

I am hoping that someone here can help me with my problem. I have tried other sites and did a search in Google and I have not found an answer to the problem at hand.

My system:
I have a clone computer with:
ASUS motherboard A8N-SLI DeLuxe
2GB Corsair RAM Memory
2 Nvidia 7600LS Video cards
2 Western Digital 250GB hard drives set on a RAID 0 configurations.

The problem:
Some time ago I purchased Acronis True Image version 8.0. I never had the chance to use it until this week. My computer slowed to a crawl and then it crashed. Days before, I had made a backup of my OS so I decided to restore it from the backup that I stored in an external HD. I have two Western Digital 250GB hard drives configured as RAID 0. The program restored the image successfully so I restarted the computer after it finished. Unfortunately now the computer will not boot up. The hard drives are okay, no problems at all, however I keep getting the following message:

My questions are these: Has anyone encountered a situation similar to mine and if so, what did you do about it?

I am by no means a fan of software RAID (at least in Windows) but in this current scenario I do not have another option.

I created the mirror and it was working fine for several months. Then it lost redundancy, but it did say a drive had failed. I deleted the missing drive from the mirror, reinitialized the drive and re-added it to the mirror. It kept randomly losing redundancy while rebuilding. I yanked the drive and have performed diagnostics on it and everything appears fine and there are no disk errors in the Windows log. Is Windows software RAID flaky or am I doing something wrong.

Another thing; every time I try and reinitialize the mirror, it creates another secondary plex option at startup. I think there are 6 or 7 entries now.

A:Can you install Windows 7 Pro on software RAID 0?

Since it's a OS drive, you will not want to do software raid with it. You will not be able to start up Windows 7 afterwards if you do.You will need to use hardware RAID instead by either using a motherboard that supports it, or installing a RAID controller card to use. Once you install Windows 7, then you can perform a software Raid. **If you need help setting up a software Raid, please go to this link for assistance.**

I need some advice on a hardware/software issue. The basics: I have Win 7 Pro 64 bit installed on an ASUS P7P55D LE motherboard which supports RAID 0,1,5 and 10 using Intel Matrix Storage Technology through an on board Intel P55 chip set. The system was assembled in Nov 2009 using two Western Digital Caviar Black 750Gb drives in RAID 1 as Drive C:\. (I now know from Western Digital Customer Service that I shouldn’t have done that, but let’s move on from there). Last December, an error message informed me the RAID array was broken and identified one of the 750 Mb drives as needing replacement. I happened to have a spare 1.5Tb WD Caviar Black at the time, so I pulled the 750Mb drive and replaced it with the 1.5Tb drive. Life was once again ‘good’. Then on July 4th (wouldn’t you know) there was a repeat of the December 2011 error message telling me to replace the other original 750Gb drive. Okay so I had another 1.5Tb WD Caviar Black laying around (please don’t ask) and did a similar swap out. That’s when I emailed WD Customer Support asking about the 750 since their diagnostic software said the drives were fine. That’s when I learned that I should be paying lots more for enterprise quality drives if I want/need RAID. Well that’s not what ASUS says in their advertising, but live and learn. All that’s prologue, because my real question is whether it’s possible to break the hardware-based RAID 1 array and set up a W... Read more

A:Hardware RAID 1 to Windows 7 RAID 1

You might be able to break it if it is truly RAID1, but I would think you'd need to run a repair to get it booting again. But, we can back up a step. Why bother with RAID at all? It's wasted on a single user desktop, especially for mirroring. It isn't a good backup method, so why use it?

If it was my system, I'd run one drive internally, cut into C and D partitions, then stick the other drive in an external housing to use as a backup drive. No need to overcomplicate a system setup, and no need to mess with dynamic drives.

Alright I have a few questions, about windows 7 pro software raid 1 on 2 IDENTICAL 2TB drives of the same production date (well 1 day difference)

What will happen when I reinstall the system? Will the raid reactivate itself or do I lose the data.
Is the raid synched at all times through software raid or does it have resynching periods? (EG 24:00 of each day)
Can I upgrade to windows 7 ultimate or windows 10 pro without the raid falling apart?
Can I go from software to hardware raid without issues (I have an X79 motherboard, Rampage IV formula, no additional raid controller) and with that I mean, if I have an hardware raid and I reinstall/upgrade, what would happen then?

Some other things: The disks contain data, 1.2TB mirrored and therefore they are Dynamic volumes
I got no additional copies at the moment.
And there is my final question, will I lose anything by reinstalling with the disks disconnected and connecting them after installing (I mean the data will be there but can/will Windows detect it under the following 3 scenarios (reinstallation/7 ultimate/10)

That is all,

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.

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
