Installation problems with 338 mB harddisk

I finally received the adaptec ESDI controller to connect to the
338 Mbyte micropolis Harddisk.

After re-installation of the microport UNIX/386 V3.0e everything seemed
to work perfect. (And a lot faster) Until I tried to re-install my
previous backed up software from the Wangtek tapestreamer....

I was not abled to re-install *any* of my 6 tapes on the new drive!
This is wat happens after:
$ strm /dev/mt/rmt0 | cpio -ivduma
The tape drive starts reading files, and after installing a number of
files (random?) the tape just rewinds and deselects, leaving the 
strm as a running task.
The same thing happens if I try:
$ cpio -ivduma < /dev/mt/rmt0
leaving this time cpio as a running task.
Also trying /dev/mt/rmt4  leads to rewinding the tape after a number of
files have been copied in.

The same thing happens when I try to write a tape! Sometimes I'm able to
get approx. 2 mB to the tape unit , sometimes 10 mB but never consistent.
However there is *never* a problem in reading just the index of
the tape with: cpio -itv !!!

I'm totaly puzzled what happens here........ has anyone expirienced something
similar, or perhaps an idea where I should start looking for the problem?

Here is a description of the boards used:
Adaptec ACB-2322A-8 15mHz ESDI controller. Micropolis 1558-15 338 mByte
Harddisk. Wangtek 5099ek 60 mB 1/4 inch tape-streamer.
The system works perfect now with 2 micropolis 1335 70 mByte harddisks and
a WD-controller.

Please send any response if you could give me a hint.
