So now we have the SCSI <--> IDE wars on this list ? I've installed a
number of heavily used Linux machines with IDE drives that have run for
several years (just over 3, the longest one) with no problems at all with
the disks. Some of these use WD drives. WD however has had a software
problem which they fixed (patch at www.wdc.com) and most drives are fixed
with new software. I've also installed other multitasking, multiuser OS's
on IDE, no sweat. Of cource I prfer SCSI beacuse of better concurrent disk
access, bigger on-drive buffers, faster drives etc. but there's a price
for it.
