Safe to recover failed RAID volume?

[Nintendo Master]

My XP desktop had a BSOD. After the reboot the Intel RAID manager saids "Failed RAID volume detected. Recover volume? (Y/N):"

I don't want to choose yes if it will wipe all my data off both drives. I'm running a RAID1 and both drive states are "Error Occurred(0)"

If I recover the volume will it just repair the array and keep all the data or just wipe everything and make me start over? I searched for this problem but can't find a definite answer.

Not sure if anyone can give a definitive answer on that
It's 50/50
Hence the reason to always have backups created
Raid1 (or any raid really) is not good when trying to recover data (ie nearly impossible)
Therefore, when you're brave enough press Yes :suspiciou

Do you think it would be a good idea to put 1 of the disks in another working PC and copy the data off that way? Will this work?

 

[kimsland]

Yes seeming both disks should be a duplicate of themselves

so i just pressed yes and it did recover the volume without losing any data.

thx for the help!

1. The 'recovery' attempt is always a first step for RAID-1 configurations.
2. If it fails, then replace the failing drive, reboot, and let it 'recover' -- should be good to go.
3. If not, THEN the backup restore would be the next step (with the new hd in place).

For Raid-0, you're force to use the backup restore.

For Raid 10 (mirrored stripes), the 'recover' should follow RAID-1 procedure

For Raid 0+1 (striped mirrors) follow the RAID-0 procedures.

For Raid 5, (striped with parity) follow RAID-0 procedures.
