Define not working. Do they grab tapes and spit them back out, completely
non functional, light flashing (could just need a cleaning tape), etc.

Subject: 4mm DAT repair recommendations?
Hi folks,
I have three external DDS2 DAT drives for a Unisys machine I've been
restoring, and none of them work. The original owner of the machine
warned me they were not reliable, but I've actually found them quite reliably
non-functioning.
I performed the prerequisite Google search for information on repairing
these drives, and instead I got results about services who repair them.
I'm all for that, but of course which one to pick? So here I am, tapping into
the Group Wisdom.
Anyone have direct experience with such a firm in the United States?
Those to avoid are every bit as useful as those you recommend.
Thanks -- Ian
Not working: the system reports 'not ready' despite issuing the appropriate
commands. I have cleaned the drive multiple times, tried numerous scratch tapes, tried
several believed-good tapes with content - 'not ready'. The former owner of the
system reports they had similar, progressive problems near the end of the machine's
service life.
Sometimes lights flash, other times not, even with multiple attempts using the same tape.
