You might want to check out how you terminate the drive and whether you have a
laser printer near the drive. I had similar problems with my HP DAT24i, and
I'm on my 3rd drive now. The first drive failed after 3 months with medium
sense errors, and in talking to HP they said that laser printers emit charged
particles that can get into the mechanism, and also that the drive wanted
active termination on an ultra controller (the guy who built my system had
enabled the termination on the CD-R). For the 2nd tape drive, I put the tape
on a non-ultra controller and moved the printer away from the computer (though
in the last 2 months, I had to have the printer in the same room due to
construction going on in my office). Now I have the drive with a separate
active terminator, and the laser printer in a separate room. We'll see in 3
months if the failure occurs again.
