SBS 2008 bare metal backup problem.

I have done full back up on the USB drive and re-created the array.
before I had 3 x 750GB, 1 failed so now i have 2 x 750GB and 1 x 1TB drive and created 2 logical drives with raid5

On my SBS backup i have backed up C: and E: drive before recreating the array.
While trying to restore using the SBS DVD (repair process) at the end I am getting error:
"The disk that is set as active in BIOS is too small to recover the original system disk. Replace the disk with a larger one and retry the restore operation."

I believe total should be around 1.36GB when I had 3 x 750GB drive and I with new array settings I am getting simialr size but but still getting above error.

Do i need to get all 3 drive 3 x 750GB to fix this? or get 3 x 1TB drive and try.

Is there any work around solution for this?

What size were and are the two logical drives that you created?

498GB and 600GB something like that
whether its with 2x 750GB + 1TB or 3 x 750GB on raid5 should have same disk size but SBS is not taking it and asking for bigger disk
Is this anything to do with logical drives thanks?

"The logical drive that is marked active must be equal to or larger than the one that you backed up and are trying to restore. "

Thanks

When you say logical drive that is marked active must be equal to or larger than one....do you mean for example: before recreating I had 2 drive C: and D:

C: 550GB
D: 600GB

Do you mean whe nI re-created array I need to create my 2 logical drives equal or bigger than 550GB and second one 600GB or higher, is that what you mean ? thanks

sorry that's just vol, i have created now whole size as 1 logical drive and testing again. will let you know thanks
The error: The disk that is set as active in BIOS is too small to recover the original system disk.

Refers to the size of the logical drive or partition (not the total RAID volume).

If your original c was 550 gig the new c (if that is the active partition) must be equal to or larger than 550 gig.
Incidently with RAID 5, if you lose a drive normally you can shut down the system (unless it can hot swap) replace the failed drive and boot up. the RAID controller will rebuild the new drive to replace the failed one. No backup or restore required.

thanks.
ya go this 1TB driver for hot swap to rebuild but raid couldn't detect new drive on same port so vendor has asked to re-create the array and install the OS.

thanks, now logical drive is equal to previous size and able to run the restoration.
