I running a RAID 5 on NT4 w/ 3 IBM 10k 18GB drives and Adaptec 2100S controller. Drives are at SCSI ID's 3, 4, & 5.
Array failed and reported ID5 was to blame. Replaced ID5 with like drive and attempted to rebuild, got to about 2% on the rebuild and the new ID5 was reporting as failed.
Took all drives offline and placed on regular SCSI card to run IBM drive fitness. Turns out ID3 drive has bad sectors. When trying to run the corrupted sector repair util, it hangs on one sector. I gave up on it after 45 min. Is it normal for it to take forever at this point?
Anywho, odd thing is, I put the server back together and still seems to work OK even though I couldn't fix the bad sector. Thought I would try some fancy footwork by mirroring the RAID to an IDE drive, breaking the mirror and running off the IDE, destroy the array, replace ID3, recreate array, reestablish mirror, and then break mirror running off the array only and using the IDE as a slave.
Any thoughts on this? My only concern is that while the machine is building the mirror, I'm getting a large amount of bad sense errors on the RAID card. Any ideas, thoughts, nuggets of wisdom?
