Another reason is that IDE drives often have higher densities. A 160 GB
SCSI disk have a lot of plates (8?), while IDE drives with the same
capacity typicly have only one or two. It basicly means that the disk is
more sensitive to errors.

(Numbers above may not be correct for all IDE and SCSI-disks, they are
just meant as an illustration)

This, like many other IDE/SCSI issues is not a IDE-problem per-say -
it's just (like it was written earlier in the thread) that SCSI-disks
are typicly designed for servers, while IDE disks are typicly designed
for workstations.
