I
recently re-learned this. As I was testing some
HDD's I had the
bright idea to
cradle them in my lap. This
was a
bad idea.
Everything was fine, for about
two minutes. Then I
accidentally slid back a little. Unluckily, the
SCSI cable was
Teflon.
Teflon does not
flex or
bend as well as
PVC or Thermal Plastic. As I slid back, the
cabling yanked the Adaptec 29160 out of the PCI slot. I half-
shat my pants and
jammed it back in. Then the
power supply clicked and the
computer died. I
waited ten minutes and turned it back on.
And the -
12V voltage was never the
same.
