It's those hard drives that cause those common PSU
failures! If you plug
them in while the PSU is running, you'll see why someone made the remark
that switchmode power supplies don't like switching loads.
Those FOOLS! (I come down hard on some dimwit people like this not
on this list, thank goodness).
That is best way to blow out HD and motherboard! PSU is expendable.
Do that job with unpowered machine always. SCSI is powered on
termination power for example. Hint: found popped fuse in a scsi
scanner I fixed. SCSI is best for "hot" swap if the hardware used is
capable of it especially that removeable rails. IDE can't redetect
specs till reboot the machine (now you see what I mean). SCSI allows
you to "hot" refresh without rebooting the machine.
I know . . . I do it too, but it's one of the most
frequently ignored
cautions.

Sheesh.
