Hi,

Here in our department, we run three IBM PC-AT's. Each with two 20 meg disks.
Each are left on 24 hours a day. In each system there is one stock (CMI?)
drive, and one after market drive (Seagate). We have not had any problems
with the disks or computers, and we have had them over one year now. That 
makes a total test time of 50,000 hours with 0 failures. Or 25,000 hours per
disk drive without failures. Not bad when you think about it.

BTW, it is my understanding that crashes are more likely during spin-up and
spin-down, as that is when the heads actually begin or stop flying over the
media.

FYI....
