Situation:

  1. One empty 120GB SSD
  2. Two 60GB SSD's is RAID 0 containing a Windows 7 installation
  3. The RAID is firmware-based (a.k.a. fakeRAID) which means it requires a driver for it to be seen by an operating system.

I don't want to use RAID 0 anymore; far too dangerous. I want to take the data from the RAID array and put it onto the single 120GB SSD. Ultimately, I want to keep the Windows 7 install completely intact; I don't want to reinstall anything.

Keep in mind I have multiple TB worth of free space to use as temporary storage for whatever transfers need to take place.

I looked into Clonezilla but it (as with most cloning software) doesn't support firmware-based RAID.

    I use to do this with XP, not sure if it works with W7, Install OS on new drive you are moving to, boot into the Raid OS, manually delete all the files and folders from the new drive you just installed, copy and paste all files from current installation to new drive (first, unhide all files). You may have to do a few startup repairs when booting it the first time.

Try EaseUS Disk Copy utility to clone a RAID 0 array to a single disk.

    Could you give more detailed instructions? Migrating the OS partition(s) from RAID to non-RAID is not as simple as cloning; often the boot entries need to be modified/repaired and, in the case of Windows, AHCI drivers may need to be enabled.

  1. Download and install the excellent (and free!) Paragon Backup.

  2. Do a FULL backup using Windows backup. You can store it on a 3rd hard disk, or USB drive or even another computer on your network. I used a networked computer. This is our emergency only, last resort, in case all else fails backup and will not be used if all goes well. Make the recovery disk when prompted. As a further precaution boot into the recovery disk and ensure you can access the backup. Do not skip this step!

  3. Now do a FULL backup using Paragon Backup. Same location if you like (this is the one we will restore later). Make sure you backup the MBR, System Reserved (~100MB) and windows partitions. Minimum 3 ‘partitions’. If that’s all you have then fine, just make sure you backup ALL your partitions. The MBR is not, strictly speaking, a partition but you will see it listed.

  4. Create the Paragon backup/restore CD or USB (I used a USB thumb)

  5. Boot the Paragon backup/restore disk you created in step 4, and make sure you can access the backup you created in step 3, If you used the network like me, then you will need to set it up using the ‘Configure network’ option. If you cannot access the backup then you will need to move the backup. Just make sure you can access the backup using the Paragon backup/restore disk before you continue.

  6. Reboot and enter your RAID BIOS, destroy your array, do not create a new array.

  7. Boot the Paragon backup/restore, now restore your backup of windows 7 to disk 0. Make sure to restore the MBR and the ~100MB ‘System Reserved’ partitions as well as the windows partition.

  8. Once completed you should now be able to boot into windows.

  9. Open ‘Device Manager’ and look for your RAID driver. Uninstall it. You should be prompted to reboot.

  10. Enter your Mainboard BIOS setup, Change the sata controller mode from RAID to SATA (you could try AHCI but if it wont boot you will need to follow one of the many guides on enabling AHCI).

  11. If all went well your done, windows will install the correct drivers for your sata controller and want to reboot again most likely, but basically that’s it.
