Thanks Brian, that was very interesting.  I tried it with my Adaptec U160
but unfortunately nothing changed.  I had a quick look into winTar, but,
alas, that's a proprietary application.  If there's actually some
problem with the SCSI adapter, then winTar apparently knows how to get
around it.  I don't know much about the SCSI low level interface...
