Geeze - you just throw 'em out?
Heck, I even fixed two ATAPI CD-ROM this month ... one had a nasty grinding
noise when trying to open/close its tray because of a dust-bunny trapped in
the tray gears, the other one wouldn't load the motor/pickup frame because
two plastic studs which slide in a guiding rail had snapped of. They were
easily replaced with suitably small screws.
I don't even remember why I did the second one; the first one was one of
those Toshiba drives where the housing is set in above the IDE connector
like this (drawing not to scale ;-))

which was needed because I was fitting it in a "luggable" case, where a
full-shape drive would have interfered with the CPU cooler.
Not to start a flame war, but for my part, I try to repair what ever seems
Off-topic: can somebody with such a unit at hand tell me what value the
switcher regulator coil in an 3com OfficeConnect Hub 8TPC is? I have a
cannibalized one here which still seems to work when I inject stabilized 5V
after the regulator...
TIA, Yours sincerely
