Nelson Stansbury - Technical Manager ask:

File and Print server

128Meg/PII333/100mhz bus
VGA
NT4/SP6
Mirrored C drives for OS 2 4.2 IDE drives 140 Meg paging file on OS drive
Internal Adaptec Raid Card with 4 WD9.2gig UWSCSI2
Cable is self terminating
SCSI ID's 0,1,2,3
Has Tape backup HPDAT12/24 on same controller card, different channel

Every 6 - 8 weeks a random drive fails, random times, usually when no
activity on network.  Different drives.  Sometimes they re-build, sometimes
they refuse.  Today it is refusing to re-build.  After re-booting the sytem
the drives are rebuildable again, for another 6 - 8 weeks.

Any ideas why?
