Degraded scsi drive on Dell Dimension 2850 raid array

But if you're thinking 'unpure' thoughts, then who knows?

But seriously, a failed drive swap should rebuild without an issue. I would go on the 'paranoid' side and run an extra backup, just to be safe.

I once had a Compaq server which had a firmware bug that caused first one drive to show failed, then two, then three, then the rest. The fix was to leave the drives unplugged until the server finsished going thru post/diags, then pop in the drives real fast before it knew what was going on.

As a matter of fact you might consider just popping the offending drive out and then putting it back in.

Some of the Dell SCSI controllers have a tendancy to fail drives that respond too slowly. The drive is typically fine and will rebuild without error. If the drive fails a second time then you will want to replace it.
