I have the above drive. It was shipped to me
bolted in an enclosure. During shipping, it
was badly shocked, shearing off the mounting
bolts and damaging a couple of components
on the electronics board. A couple of resistors
and caps had their leads cut. Some creative
soldering fixed that. One diode was smashed.
It was on of those little clear (glass?) diodes.
Are those called zeeners or something that
starts with "z"? Anyway, I didn't have a
replacement, so I just removed the leads and
left it at that. Later I decided to go ahead and
try the drive, and it worked. If somebody has
the schematics, the silkscreen next to where
the diode was is "C1" (it is in one corner of the
board). Are there often nonessential components
in older hardware? Is it actually nonessential or
is some signal being compromised or some
other component being overstressed?
