I have trouble reading old tapes from my 4mm WangDAT3200 (2 Gb) tapedrive,
while I succeed in overwriting/reading with the same drive.
Her is the picture:
dyret /# /local/gnu/bin/tar tf /dev/rmt0h
/local/gnu/bin/tar: Read error on /dev/rmt0h: No space left on device
/local/gnu/bin/tar: At beginning of tape, quitting now
<clean with cleaningtape>
<turning drive off>
<washing with tecnical spritus>
<another used tape is put into drive>
dyret /# /local/gnu/bin/tar tf /dev/rmt0h
