The block size set in the tape driver is different from the block size
on the tape. Either you know the block size of the tape and set
your driver accordingly:

	mt -f /dev/rmt setblk 5120

or you set your driver to "variable blocksize" which allows to
read all tapes the drive is capable of:

	mt -f /dev/rmt setblk 0

If you want to know the current setting of your driver, call

	mt -f /dev/rmt status 2
