Booted into mirror drive in 2003 SBS Server

Hello all,

This morning we had a missing or corrupt file error on boot up for our 2003 SBS. I tried the memory and they all tested fine, the drives also tested fine. I booted into the mirror drive successfully (during the startup we had a choice of booting into OS or the mirror drive). Now it is synching again in the computer management. What I dont know are the next steps&Do I just change the mirror drive to 0 and the bad one to drive 1? Then format the bad drive and reestablish a mirror? Does that work with Dynamic drives? Please help me with my next steps. Thank You.

    If your drives are mirrored, then it matters not whether one is 0 or 1... they're a mirror image!  

    But what does matter is that if you had an error that corrupted the drive you should carefully scan that drive to make sure that it doesn't have any surface errors which will cause a future problem.  If it does, then you need to break the mirror, replace the bad drive and re-establish the RAID.

    Thanks Yet Again Jeff! What I found out is that if I reactivate the disks and they remain in healthy status after (instead of showing error) then it probably was a temp I/O error. If the disk resorts back to the I/O error then I need to do as you stated and break the mirror and change the disk.

    Saved again by basic redundancy&lol!

    Don't wait for the disk to error again... because Mirrored drives do not protect you from file corruption... just disk failure.  If there's massive file corruption then you'll lose data on both drives.

    Take the time to do a low level disk scan which might take a couple of hours... there are plenty of free utilities out there which will perform this task... but it must be done off-line.
