How do you know this?
I ask because I feel I got hit by a similar problem with a Wangtek
SCSI DAT drive. After a cool-down period, I can do writes to the
drive for about 10 minutes. Then the system locks up. That 10
minutes time period gets shorter and shorter as the system stays on.
If I wrap the system in a nice comfy blanket with a few plushy animals
(teddy bears work best), writes work for less than 10 seconds.
By rearranging the various internal components so the DAT drive isn't
near anything, it works fine.
My question: what is it about the heat that causes the OS to crash?
Or is it not the OS, but the system as a whole? And what is it about
SCSI tape writes? Other SCSI activity works fine.
Confused.
