OT:Need help with old Raid array

[Boaz Bezborodko]

I came in this morning to find that the Netware server detected a
corruption in the data volume and deactivated it.  It took two rebuilds
to get the data back and only some inconsequential files were lost.  It
seems that there was an I/O error last night that caused the problem.

My questions is whether this is a problem I have to worry about (i.e.
imminent hardware failure) or just a glitch.

The hardware is a Compaq Storage Array connected via a Compaq Smart
Array 3200.  The array is set up as a RAID 5.  I have had no problem
until now.  But during the rebuild there were times when the drives on
the array would stop and gave me the feeling of a failing drive trying
to get data off a bad sector.  None of the drives failed and it seems to
be working OK, right now. 

Any suggestions?
