Try setting hardware compression off.
Either with jumper on the DAT drive or with mt
man mt
...
datcompression
(some SCSI-2 DAT tapes) Inquire or set the compres
sion status (on/off). If the count is one the com
pression status is printed. If the count is zero,
compression is disabled. Otherwise, compression is
enabled. The command uses the SCSI ioctl to read
and write the Data Compression Characteristics mode
page (15). ONLY ROOT CAN USE THIS COMMAND.
