Need to clone a RAID mirror (two drives) to a non-RAID, single HD

Q: Need to clone a RAID mirror (two drives) to a non-RAID, single HD

I have a computer running XP which was built with a pair of 80 GB hard drives which have met their limit in terms of free space so the user is wanting to upgrade. These drives appear to be running in some kind of RAID setup via the motherboards built in RAID feature (not a PCI card running this setup). This is the first time I've encountered a RAID setup in a home-based PC.

One other minor problem I have is this motherboard (an Asus ABN-VM) only has two SATA ports, which are both used, so I'm going to have to clone to an external drive as an image file and then connect the new single 500 GB drive and clone back from that image to the new drive. However, come to think of it, I have an adapter that would allow me to connect the new drive to the PC via USB so... scratch that concern I guess.

I decided to take the plunge and see what Clonezilla would do with the external USB drive I have and the two 80 GB drives in the PC. When the main menu appeared I told it that I wanted to work in device_to_image mode and then told it to mount all drives. It then asked me to select the drive I wanted to use as the source but it presented both drives as individual drives, not a single mirror as I was expecting the motherboard to present it as. So... don't know what to do from here.

Perhaps there's another cloning utility out there I could run from within Windows or could boot from a disc that would recognize this array and clone it to a single drive properly. Any suggestions would be greatly appreciated! Thanks in advanced!

Preferred Solution: Need to clone a RAID mirror (two drives) to a non-RAID, single HD

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.)

A: Need to clone a RAID mirror (two drives) to a non-RAID, single HD

If the drives are mirrored then imaging one drive should be all you need. If the drives are striped then the two drives are being combined together to make ~160GB drive.

I guess to determine this, what is the capacity of the main 'logical' drive? 80 or 160'ish?

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.

So currently my gigabyte motherboard has 2-1TB drives in a mirror raid as my secondary drive for data storage and 1 250GB single drive for my OS. In the BIOS I have the setting set to RAID for my hard drives, which I set this after I loaded windows when I first started, but now my 250GB single OS drive needs to be reloaded, but my XP disc will not see the drive since I have it set to RAID. I'm having trouble loading the raid drivers from gigabyte and I thought it would be easier to set the hard drives to AHCI mode and unplug my 2-1TB drives, reload windows on the 250 then plug my 2-TB drives back up then switch the BIOS back to RAID, but I am worried that this will mess up my RAID on my 2-1TB drives?? I would hate to experiment and lose the data on those drives. Will switching modes mess up my RAID???

A:Gigabyte Mirror Raid on backup drive need to reinstall XP on single OS drive question

Pull the drives off the system, do whatever you need to do to get XP installed. When that is working, change the settings to RAID, then reconnect the mirror.

It's best to install XP with nothing else on the system anyways, otherwise you risk having XP decide to install your O/S on drive "D:".

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.

A:RAID drives + non raid drive..possible?

Read other 16 answers

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.

When using the Microsoft Recovery Console in (RAID mode attached w/ both drives) logically there isn't ... Read more

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 have a 500 GB hard drive and a 250 GB hard drive. I want some kind of redundancy to be setup with them. I have both drives up and recognized through disk management. I don't have a RAID controller card or anything of the sort to do it hardware wise. Is there something that I can do inside of windows server 2003 to make them mirrored or something to the effect that if one goes down I can rebuild it. I also know that it can only be as large as the smalled HD. So it's going to be limited to 250 GB. And the last part is if I partition part of the 500 GB hard drive off can I still use the other half.

I have 2xWD black label 500GB in mirror raid. Obviously they are set as primary now.
I want to make the SSD primary, the raid secondary drive and do clean windows 7 install on the SSD.

Before opening the box I would like to make sure about few things.

1. How do you set a mirror raid as a secondary? Do you need to move any jumpers or just set it from the bios?

2. Since I don't have CD on this computer I have to either make a bootable flash drive OR if there is an option to install windows on the SSD from the current setup (while with my existing windows install and the raid as primary) and then switch the SSD as primary and boot from there? Any caveats here?

Anything else i should know before doing the move?

Thank you!

A:Going from HDD mirror raid to SSD, what I should know?

If you want to be sure, remove the RAID drives, or just pull the power from them. Install the SSD and do your clean install. Once complete, shut off the computer, reconnect power to those drives, and boot up again. You should be able to verify in your BIOS that the SSD is the first drive the system looks to when booting.

I am not a hardware person at all. I have a pretty good hardware problem. Can someone please explain the best and most practical way of handling this situation. I want to do either a RAID or a mirror array. But it needs to be software managed, it's not going to be a hardware set up. I have two hard drives but they are not the same size. Is there a way to set this up virtually? If anyone has any input at all feel free to post. This is under a time constraint so the faster the better! Thanks!!!!!


Yes, you can use different hard drives no problem. The size of the smallest one will define the size of the array. As for how to set it up.. Just google for your specific OS. Like "windows raid".

I searched but I can't find the same issue. I know how to reconnect a drive in a Mirror raid when the previous has failed, then the system will copy all files and rebuild the Mirror.
But my problem is the following:

- I had on Mirror raid consisting of 2 identical drives, for data security.
- Yesterday, I put a new drive in the system (not for the Raid array, just a regular one for other purposes)
- I had to rearrange all the drives inside the pc and redo all the wiring and plugging.
- When I started Windows, it said one of my two raid drives was missing and that the redudancy failed. I thought the drive was dead but it wasn't.

- I actually right clicked on it in disk management and did a "reactivate volume", then the drive went back online and worked, it doesn't seem to be damaged at all and is marked at "healthy". I did a quick scandisk and everything is fine.

- Now my raid Mirror is broken, I have the 2 drives but they aren't connected together.
- They are still marked as "dynamic" while being separated.
- When I right-right on one of them I don't have any option to reconnect them into a Mirror. Extend volume" and "add a Mirror" are greyed out.

I seem to be stuck. Any idea of what should I do?

Thank you for helping.

A:How to re-mirror a drive to RAID

We see nothing but problems here with RAID ever since Win7 beta. Not a single good report of RAID, almost daily reports of disasters. It isn't even redundant - the very first letter of it's name! - since users often lose everything when a drive fails or crashes.

You are best off to unRAID your drives and install Win7 to the fastest drive, or to an SSD which is the best upgrade you can possibly have - even better than buying a new PC without one. Then after install add back and format the other drive(s) for storage, data and the all important and reliable backup images taken just after install and setup and then regularly.

Then focus on doing a perfect Clean Reinstall Windows 7.

I wish I had better news for you, but it is not something I mess with because it only gets worse, never better, compared to the perfect installs we have helped millions get here.

I have had to reformat my hard drive because I thought it was the best way to get out of a mess I got myself into. You know the computer from HELL day.
I have a RAID 1 (Mirror) configuration and really want to keep it. This system worked for over 3 weeks flawlessly and all of a sudden I think I had some software issues or graphic card issues. I then did a memory check and the disk corrupted my system.
So I am at ground 0 and I can't even load XP Pro into my system.
For some reason it thinks there is something on my drive and it is in a loop of booting, then it formats my drive, then it thinks there is a windows folder on it still and askes me to write over it. I say ok to let it write over it and I never see any graphics it just reboots and repeats the whole process over and over again. I am loading the software correctly I see the license agreement but it never starts to load just goes in and copies the 3rd party software like it should then it writes some files on disk but in a dos type enviornment. I never see the black XP screen in this whole process.
Do you think it is seeing the mirrored drive? Any ideas?

11 hours between last night and today... I need a drink!

Thanks for any help you may have.

This is what I would try when you're at this point installing XP - do a totally clean install
( If an existing Windows XP installation is detected, you will be prompted to repair it. At this point hit the ESC key (do not repair).
- The screen will now list all existing partitions and un-partitioned space for each hard disk. Use the cursor/arrow keys to choose where to create the new partition. Press D to delete an existing partition or press C to create a new partition in un-partitioned space. If you press D to delete an existing partition, ) make sure you delete the partition - then install on you're newly partition drive

System is a Dell Dimension 8400 with 2 identical SATA HDD's using Windows XP Pro SP2. How can I repair this raid to access the data that is on the drive(s). My only thought is to get the raid drivers to the PC and have them on a bootable floppy or USB device and press F6 when booting from the Windows XP Pro CD. Correct me if I am wrong in this process. I ran the disk utility on the system to try and identify the BSD, but nothing shows up. The BSD stop error points to the NTFS file system. Yes, I have a copy of an ERD Commander disk to access the drive, but I did not boot with any F6scsi (SATA) drivers for the raid. It did not see the C:\windows directory so I am assuming the reason is the drivers mentioned above.

Help on this would be greatly appreciated.

Unfortunately, my colleague will loose his important data, since there is no backup of this stuff. I am well aware of the issues with no backups, since I personally have lost information in the past. Now, I have 2 to 3 locations where I store that information to avoid loss of xtuff. Yes, I ama a techie, but I don't wprl work with RAID for this reason and would like some help here.

I have 3 RAID mirrors, 2 X 2Tb and 1 X 1.5Tb.

The small mirror (1 X 1.5Tb) degraded so rather than replace the dead 1.5Tb (after securing the data) I deleted the volume and bought 2 X 4TB drives.

Replaced the 1.5Tb discs with the 4Tb discs and double clicked on the Intel Rapid Storage Technology icon and loaded the program which saw the new discs as 3,815Gb drives

I then created a new RAID mirror, no problems. BUT, the display shows the 3,815Gb discs but the mirror size is only 1,718Gb.

Could someone, more conversant with the topic, please confirm that RAID mirrors are limited to 2Tb? As it appears that my new mirror has lost a factor of 2Tb.

I contacted Gigabyte (the manufacturers of my P55A-UD7 motherboard) and they suggested that I SHOULD be able to build 3Tb mirrors. It seemed strange to me that they couldn't say if the MB could or couldn't handle larger that 2Tb mirrors, after all they are the manufacturers

Maybe someone more aware of Intel limitations can answer my query?

My MB (and whole system) is a couple of years old and I am running Windows 7 64bit with 8Gb ram.

Thanks in anticipation

PS I got a message that the drivers for the 4Tb discs failed to load!?

A:Can I create a RAID mirror with 2 by 4Tb discs?

larger than 2tb hard drives require them to be formatted in GPT format, and if you wish to use them as a primary boot drive you must make sure your mobo supports UEFI or unified extensible firmware interface.. thats a mouthful.

I知 currently running a single PC that handles my small retail store operations and I知 feeling vulnerable to a possible hard drive crash that would put a halt to my business for a day or three while I get a replacement and restore all data. I believe the best solution would be to run a dual mirror drive so I could seamlessly switch over if one drive failed, without missing a beat. Am I correct that this would be the best solution to address my concerns?

Next, the PC I知 currently running is a HP rp5000 and I知 told that this model does not support a RAID configuration that would allow me to add a mirrored hard drive. I知 being told I need to buy a new PC with a dual drive (RAID1) configuration which will cost me between $1000 - $1300. Is this true that my current computer can稚 be configured to run a dual drive and are there any less expensive work-a-rounds anyone can suggest?


A:Question about Mirror HD RAID setup

Mirror raid would definitley be useful. Bear in mind that it only helps against drive failure, not against viruses etc. I assume you woul dalso back up to an external on a daily/weekly basis, in case ofcatastrophic failure.

as far as setting RAID up goes, not sure exactly on your specs, but you should br able to get a raid card- think they run around 20-40 dollars, but not sure. Certainly not too much. It plugs into an expansion port and allows you to plug drives into it, exactly as if it was going to the mobo. The card then allows raid, although it will need rivers- al supplied and not a problem.

If you go that way, and dont feel confident, probably worth considering getting someone to do it for you. That way at least you know it will be done correctly and give you what you need.

Checled your spec, and seems you have free pci slots. Suggest that one of these


Would probably be suitable, but check first.

Hope its useful

Motherboard: Asus P7P55D-E Pro
Windows 7 64bit
4 Hard Drives, 1 is boot drive (C), 1 is non-RAID and 2 set up as RAID 1

I am about to replace my Boot drive with a Crucial M550 SSD, by cloning the current drive to the SSD. This appeared a fairly straight forward procedure until reading of the problems associated with running in AHCI mode. I've seen the tutorial and the need to modify the registry to allow installation of AHCI drivers.

Because I have RAID 1, the Intel P55 chipset SATA is set to RAID in the BIOS. I'm presuming that if I were to change to AHCI the RAID would be lost and the PC would likely not boot at all.

If possible could you tell me the best procedure to follow to set up my SSD with my current set up. I'd prefer to avoid fresh re-install and clone if possible.

Thanks for any help.

A:AHCI and Installing SSD on Mirror RAID 1 Set Up

If you have RAID set up with the same controller that the SSD will use, the RAID drivers have the same functions as the AHCI drivers. You do not need to change to ACHI.

I have a 64-bit Windows 7 system that is functioning fine.  I have two identical hard drives (one is the drive Windows is currently installed on) and want to set up a RAID 1 mirror without reinstalling Windows.  The hard drives are both Western Digital 2TB Black (http://www.wdc.com/en/products/products.aspx?id=760).  Both are fairly new and are showing no signs of problems.  My motherboard is the ASRock A770DE+ (http://www.asrock.com/mb/AMD/A770DE+/).
When I go into the BIOS and switch on the RAID and configure it as a mirror, Windows will not boot.  The Windows logo comes up but then I get the blue screen of death with an error code of 0x0000007B.  If I turn the RAID off in the BIOS and reboot, Windows boots normally.  I tried installing both the AMD RAID drivers and RAIDXpert Utility (http://support.amd.com/us/gpudownload/windows/Pages/raid_windows.aspx#2) and changed the registry settings suggested by Microsoft (http://support.microsoft.com/kb/922976) but nothing has worked so far.  Does anyone know why this might still be happening and how to fix it?  Thanks in advance!

A:Adding a RAID Mirror to my System and Getting BSOD

<<...want to set up a RAID 1 mirror without reinstalling Windows.>> 
I don't think that can be done.  In order fot the O/S to be mirrored, it seems that the RAID must already be in place, prior to Windows installation.
Just opinion.
You are getting the BSOD because the RAID is not properly set up and the system can no longer boot to the single drive with Windows on it, IMO.

I'm looking into replacing the mirrored drives in my IBM xSeries 235 with larger capacity drives, and was wondering if
anyone could tell me if it is possible to remove and replace the secondary with a larger drive, let the mirror rebuild,
then replace the primary with a larger drive, and once again let it rebuild... then, (and this is the iffy part...) can I boot from an Acronis or Easus disk (or similar partition utility) and just resize the partition to use the entire drive? As is understand it now, if I rebuild the mirror with larger drives, the capacity will still be that of the original (smaller) drives unless and I can somehow resize the partition.

Any advice/help is appreciated!

I'm just wondering... I'm setting up a server and planning on having either a RAID0 or a RAID5 array of SCSI disks.

I could potentially use a SCSI RAID1+0 setup for my backup needs, but I've been thinking along different lines. My system drive/array will be around 300 to 450GB in SCSI, and I'm planning on having a large capacity sata disk or two in RAID1 for data...

... while I know I probably can't use the same controllers, is there any cheap and easy way by which I could have the system drive (scsi striped array) mirrored to a dedicated sata drive for backup purposes, such that if I lose the whole striped array at some point, I'll still have a backup of the lost data with which to build a new array to replace it with?

A:Mirror SCSI RAID array to SATA disk?

The good thing about Raid 5 is if one disk starts to die it gives you warning and time to pull it out and rebuild it without missing a lick. If the controller goes you can replace it and your drives will still be fine.

Now if you want to back up your entire network to a SATA array then i would advise investigating Data Protection Manager 2010 (DPM 2010). Full backup to a disk array every day and incremementals every 15 minutes, then a tape backup to take to the bank on the weekend.

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.

Simplest thing to do is to just load W7 and get it over with...but am just smart or stupid enough to consider alternatives...

I have a pretty stable WinXP install but have run into games that require 7 (and DirectX 10).


Can I install W7 on a non-raid HDD (already on my machine) while keeping WinXP on the 250 GB mirror thus avoiding application reload AND potential for issues with the RAID array?

My initial thought is to unplug the mirrored drives and install W7 to the single drive. Replug the mirrored HDDs (same ports). Edit the Boot sequence to allow choice of XP or 7.

How badly would this go?

A:Desire to keep WinXP on Mirror RAID with Win7 on separate HDD

Not well with Win7, which doesn't much like RAID.

A lot depends on the controllers which will need to provide both RAID for XP and SATA/AHCI for Win7.

You can try booting WIn7 to see if it sees the target HD, then try install.

If this fails, unplug the RAID while taking careful note of its settings, try install of Win7 to target HD with nothing else plugged in at all. The SATA controller should be in AHCI mode.

I have tried to create a RAID 1 mirror drive on my 64 bit Windows 7 Professional system. I have installed 2 additional Seagate 1Tb drives (ST1000DM003) and when I tried to Add Mirror and selected the other drive it looked like it was working but there were 2 boxes that came up that it was not formatted try later, and also that it couldn't assign the drive letter. When I tried to assign the drive letter, I get an error box with "Virtual Disk Manager" in the title and a message "The system cannot find the file specified". When I search for that I find many references but mostly with external USB drives and none of the resolutions helped. Trying to format gave a different error and failed. I found that in Device Manager under Storage Volumes there is a Generic Volume with the error "This device cannot start. (Code 10)" Both drives show up under Disk Drives with "This device is working properly." Under Disk Management both disks show Dynamic,Online and Healthy and the upper portion shows the Mirror volume. I tried to update the driver on the Generic Volume with the error and it says it is already using the best one. I went back and broke the mirror and used Diskpart to Clean both drives to start over. I created Simple volumes on both, formatted them, assigned a drive letter and was able to store files on them. I then made them both dynamic successfully and could still store and read files on them so I know the drives are good. I also t... Read more

A:Can't Create RAID 1 Mirror Drive on Win7 Pro, 64bit

I believe you will have to set your sata controller in BIOS to Raid (which may keep your OS from booting unless it was installed that way) and on boot up you should see a raid screen. Hold down the Control Key and press I to enter the raid set up. set the drives up there and it should work. Make sure they are on the same controller.

I should mention that raid may cause you more problems than it is worth, and if you are doing it as a backup, Raid is not a backup and will not serve as one. You will also take a performance hit with raid 1 too.

I received a "critical" message of some sort regarding my RAID mirror array. I have 2 of the exact same type and size drives in the array, purchased on the exact same day, about 2 months ago. No problems until today's boot. No modifications to the array since first configured. The computer uses Windows 7. Any ideas how to investigate or resolve this issue? I am currently running chkdsk.

More details:

Drives are WD Green 1TB SATA (32MB cache)

Mobo is AMD

PSU is 550 Watt Logisys

Each drive has it's own set of "hard drive fans" attached to it

The SATA cables have a metal locking mechanism that securely keeps them connected

Update: chkdsk just finished and reported that no errors were found on the File System

I'm hoping someone here can help. I'm very new to Raid, so you'll have to excuse my ignorance here. I'm using an HP pavilion p6210Y with 2x 2TB, WD Caviar Green's trying to set up a raid 1 array. I've reached the Nvidia raid array setup utility, and it appears I have successfully loaded the raid drivers.
After doing this, I inserted my Windows 7 x64 home premium install disc, and it sat on "Detecting storage devices...". After a few minutes of this, I was presented with an Error stating "No disks reserved for raid use, raid disabled." Then shortly after, switches to a message stating: "Reboot and select proper boot device or insert boot media in selected boot device and press a key."
I'm now unable to reach the Nvidia Raid setup, and unable to load the windows disc.

I'm certain the CD drive is good, as it works fine in another computer.

A:no disks reserved for raid use Raid disabled - Raid 1

Do you have Windows on the drive now? How did you load the drivers? Drivers won't function without an operating system, so I'm a little confused about exactly what you did.

How did you run the setup utility? Does your machine support hardware RAID or are you using software RAID? Are there RAID settings in BIOS?

Does the final RTM Windows 7 support SOFTWARE RAID-1 (dynamic disk mirroring)? I know it supports fake-raid and hardware raid but I want to use software raid because my disks are of different size. I don't want to try it myself since I would have to convert my disks to dynamic.
Windows Vista didn't support it. XP had it disabled but could be hacked. It was enabled in Windows server 2003 (and probably others).

yes it does. It wasn't long ago that I used it.

Is it possible to setup a mirror array with an internal drive and an external drive setup with esata? The main reasoning behind this is that I want to make a backup of one of my internal drives. The internal drive is 1.5TB made into two partitions, one 500 and ext3 and one 1000 and ntfs and the external is 750GB ntfs (I could format it to ext3) with no partitions. They use the same sata controller, so I can set it up in the bios as a mirror array.

I've done some research into it and it looks like it could work, but still want to be sure that there will be no problems.. My external drive is a little slower than my internal simply because it is slower to spin up in general. Would this slow things down as it waits for it? Or will it just rely on the one drive until the external is working? Do I need to do any setting up other than in the bios? I'm using Ubuntu 9.04.

Am I better off just using a backup program?

Sorry for all the questions, it'd be great if this could work instead of relying on just doing a backup every now and then.

MOBO = Gigabyte x58a-ud5

I just got 2 SSDs I'm trying to put in RAID0 and hopefully clone my current install. When I change the bios settings to set the intel RAID controlled to xhd and raid but try to boot from my windows installation it wont boot, it gets to ''starting windows'' and then BSOD. When I turn the RAID setup off and try to install the XHD drivers the install aborts saying ''this is not a RAID setup". Is there something I can do to get the drivers installed on my current setup then clone it to the RAID drives?

A:creating RAID, can I clone my install to it?

the other option I have is to plug my current OS drive into one of the other SATA controllers on the MOBO which arent set to RAID and maybe windows will boot then and allow me to install the XHD drivers before cloning.

I have 2 80g hard drives in a RAID array operating as one 160g hd. I have an IOMEGA 160g external hd.

I just discovered that Norton Ghost ( came with the Iomega ) does not support ghosting raid arrays.

So, is my best option to do a disk copy from Ghost in DOS? My goal is to be able to have a complete restore after a fatal crash. I am not concerned about the amount of space used since my backup drive is the same size as my hard drive and I don't intend to use it for any other purpose.

What problems would I encounter if my hard drive(s) crashed and I wanted to restore from the disk copy?

What is the advantage of an image file other than being smaller than cloning?

Any advice would be apprecieated!

A:Ghost, clone and RAID Array

A Image is no better or worse than a Clone. The only advantage of a clone that I see is that you can mount the clone disk and actually access all of the files on it. With the Image you need to use a Ghost utility to access an individual file. The only down side is that creating an image file is a little slower than a clone. This is caused because of compression.

Okay here the scoop, I have two 80 gig Seagate SATA hard drives. I have had these in a RAID 0 for the last couple years since i got them. I just went through a system crash last week and the ***** I am did not have my files backed up. Anyway I would now like to setup my two SATA drives so that they are not in a RAID 0 or 1, but just to have 2 individual drives that i could write information to as i see fit. ie keep one for all my software and keep one with all my pics, vids and other stuff.

Is it possible to take an exising backup of a single drive,
and restore it to a newly created raid 0?

As in,
I have a 64gb SSD, it's backedup.

I want to get another 64gb SSD,

Will I have to re-install everything or can I just restore the backup and let windows find the proper drivers ?

A:Single to Raid ?

Hello Symp,

If you created a system image of the drive and saved it to another drive than what you wanted to use in the RAID 0, then yes you can do a system image recovery to the new RAID 0. In addition, since the image is of a smaller drive than what you will be restoring it to, you will also need to use Disk Management to extend the drive into the left over "Unallocated Space" after the recovery.

Hope this helps,

A:Upgrade from Single HDD to Raid 0

Hello and welcome I hope you enjoy your forum time.

Now about this Raid setup. If you look around the net you will find that the increase in performance is negligable, yet the risk of losing part of the set and therefore your entire system, is much higher than one drive bombing out on you.

I would not recommend this to anyone. However if you are determind the best way is likely to image your system using Macrium reflect and then 'restore' it back to the array.

Okay. I have been doing a lot of cloning and migrating an OS before but I haven't done cloning or migrating an OS from dual drives in RAID 0 mode.
It's not my PC. Someone is just asking for my help. Is it a different approach or is it just like working on a single drive? Can Macrium handle this?
Any input and sharing of personal experience is much appreciated.

Btw, I know clean install is the best way to go, but I was told by the PC owner that she can't afford to install all her programs back due to time issues, etc.

Hi there! This is my first post here. I bought a intel 320 160g gen3. Looking to clone my raid o to it. I may be over simplifying it but can't I just install the SSd in the 3rd Sata spot clone to it from the raid then just change the bios to boot off of the SSd and change it to ahci? Then keep the raid o as is for storage of games and such. I am not putting any important data on the raid o purely a gaming computer. Fresh instal isn't an option btw.

A:Cloning from raid o to single ssd


You could try this tutorial:

SSD - Install and Transfer the Operating System

But...I would be cautious : the unknown here is how the SSD (in a non-RAID configuration) handles the clone of the existing disks (in a RAID0 configuration). The registry will contain information pertaining to a RAID, and I'm unsure how the SSD will handle that - perhaps someone more experienced could provide some insight to that.

The safest option is always a clean install.

Good luck,

I had my Os disk crash on me and eventually went the route of putting two SATA disks in together with the Raid single 250GB disk. The problem i have now is that the raid disk which has some 150gb of info on cannot be accessed. Windows XP asks me if i want to format the disk?

I run a Asus P4C 800 Delux mobo, 1 gig of ram.

1 x 120gb on SATA 1
1 x 80gb on SATA 2

Is there anyway that i can get access to shift the files on this disk to my 300gb mobile disk?

Raid 0 does nothing for security of the data. If you lose one drive you lose the data. If you want security for the data the more drives the better. If on the other hand you want to speed up your disk writes and have a raid controller raid 0 will help.

I am in the process of planning a new Gaming PC build and I ran into a snag, and can't find any tests online to back up my decision.

For a gaming PC which of these similar cost hard drive setups would offer the best mix of speed and reliability:
Raid-0 2x 500gb SATA-II 3.0Gb/s 16MB Cache 7200RPM HDD
Raid-0 4x 160gb SATA-II 3.0Gb/s 8MB Cache 7200RPM HDD
150GB Western Digital Raptor 10,000RPM SATA150 16MB Cache

I'm in no hurry to complete my build, I was also considering a solid state Raid-0 if the prices becomes reasonable any time soon.

I would have to add a storage drive if I went with the WD Raptor.

A:Raid-0 @ 7200 vs Single @ 10,000

RAID-0 is not a reliability technique; Raid-1 is the fault tolerant solution, but even it needs backups;

Without an adequate backup solution, NEVER use raid-0 as any failure will immediately
force you into a reinstall.
