Hi
It might be more an electrical than software question, sorry if somewhat
OT.
If I connect an external 100MB zip and an internal HP DDS-1 tape drive to
the dc390 adapter, I can tar zip to the tape. If I connect them to the
TRM-S1040 (dc315) it aborts with
tar: /dev/st0: Wrote only 0 of 10240 bytes
tar: Error is not recoverable: exiting now
and in dmesg:

Separately accessing the zip and the tape works on TRM-S1040 too. The
problem appears also if I just access the zip and the tape simultaneously
from 2 processes not transferring the data between them.
On loading the driver it reports:

Termination turned on on the zip, at the tape end there's a passive
terminator. The cable to the tape is pretty bad, I had to replace it in
another computer, but the tape IS SLOW. And it works on dc390.
Just wanted to make sure it's not a software bug?
Thanks
