How to remove a Raid 1 Array and rebuild in Windows 10.

I have a Dell machine running Windows 10, that had 2 SSD's (D1 SATA Port 1,D2 SATA Port 3) in it, they where set up as a Raid 1 through RST.

 

I took the second drive (D2) and cloned it for another machine (D3), my boss said i had to remove the partitions from (D2) before i put it back with the orignial machine (D1 and Raid).

 

I did that plugged the drive back in (D2 SATA Port 3) but when i boot the computer it comes up with inaccessible boot device.

 

The machine boots just fine from the main drive (D1 SATA Port 1), but the minute i plug the second drive in (D2 SATA Port 3) it refuses to boot.

 

With just the main drive (D1 SATA Port 1) it boots, and i go into Windows 10 to remove the array or set back to normal, i am unable to in the Intel RST application, also with Windows 10 i can not use the Ctrl + I method.

 

I see other people say that in the BIOS switch to AHCI and change the RST in Windows 10 and switch back.

 

I can not lose data on the main drive (D1).

Hello DoyleChris,

 

Based on the description of the issue, the second drive is out of the RAID structure.

 

Recommended steps: Set both drives as Non-RAID from BIOS.

 

1.During POST, use CTRL-I to enter the RST BIOS Extension.

2.Mark the drive as "Non-RAID".

3.Reboot your system

4.Then, create a RAID 1 from the existing drives.

 

Notes:

 

1. This key combination may have been disabled by your computer manufacturer. If you are unable to enter the RAID BIOS extension, please contact your Original Equipment Manufacturer (OEM) for instructions.

2. It is worth noting that you always have to back up your data.

3. Also, in BIOS > Boot Device Priority, make sure the RAID volume is selected as boot device and not the newly inserted drive.

4. You should be able to delete a RAID 1 mirror without losing data if the RAID 1 volume is: The only volume on the array or the first volume in a matrix RAID configuration

If you ask me, I would do the following:

 

  1. Backup (clone) the first drive to a third drive.
  2. Verify can successfully boot from image on this third drive.
  3. Shutdown and reinstall the second drive.
  4. Power up and go into BIOS Setup and invoke the RST OpROM.
  5. Set both drives to non-RAID.
  6. Create new RAID array across the first and second drive.
  7. Boot from the third drive
  8. Clone the third drive to the RAID array.
  9. Verify can boot from the RAID array.
  10. Remove the third drive.

 

This is brute force way top handle this but guaranteed to get the job done without any chance of losing the original contents.

 

Hope this helps,

...S
