Fixing a Micropolis 1375 drive?

Hi, A friend of me recently got a nice machine, a ND (Norsk Data) Satellite Network Gateway. (For people wondering about Norsk Data, check www.ndwiki.org) Anyway, the drive in the machine is a Micropolis 1375 scsi drive. And it stopped working. Of course it was "goo" on the head assembly bumper(s). He has removed that and inserted a paper strip, but the drive still doesn't work. Are there any other known failure modes for the Micropolis 1370-series drives? Description of symptoms (translated by me, any errors are mine): - the drive spins up - disk activity light (on machine?) turns on - after a while the drive reduces RPM noticeably for about a second the last two steps repeats, and after about 5 minutes the drive spins down and stops rotating. But the disk activity light still blinks, and a faint clicking noise is heard every time the disk activity light is on. He also wonders if moving the electronics from a different 1375 drive to his drive would work, assuming he could get one that works. Has anyone done this? (those refurbished Micropolis 1375 drives at about USD 400 looks a bit suspicious - the technical data is different) -- Regards, Torfinn Ingolfsen, Oslo, Norway
