My first inclination is to think that the card is a raid controller
and that the first disk has failed. Part of the "conversation" is to
identify each device to the controller. These are smart devices
these days. I would check disk 0. The disk itself is probably OK,
but its controller may have failed.

The RAID card seems to have four SATA devices attached, apparently all
working, which are formed into three arrays

since there are two 80GB disks ST380013, those are both likely members
of the RAID 1 74GB array#2

The single 500GB ST3500320, is likely a single disk volume, 465GB array#1

and the single 1TB WD1003FZEX is likely the single disk volume 931GB array#0

so I'd say the physical and logical disks are fine, and that at some
point the RAID controller is talking to them, the issue seems to be the
server is sometimes having issues negotiating PCIe links to the RAID card

if you're lucky try removing and re-seating the PCIe card in case it's a
loose contact, but other people seem to have either failed capacitors or
a mismatch of PCIe generations between the card and the motherboard
