Please, tell me more.  We have installed a large number of the Wangtek
60 Mb tape drives over the last few years, and every now and then one
hangs.  The tape stops, the light on the cartridge drive stays on and
the associated cpio process hangs.  Only a reboot clears it.

We usually find that by replacing the controller (Wangtek Assy 30850)
the problem is fixed.  Our supplier hates honouring his warranty, because
it "works fine when I try it".  Of course, he tests it under Dos.

Does anyone know if this problem has definitely been fixed in later
revisions?  The controllers are marked with revision letters, so something
must have changed.

Thanks.
