That mount point is unnecessary since 1.3.3, see Users Guide:

^^^^^^^^^^^^
unnecessary since /dev/tape is the default device name for
mt version >= 2.0.

Probably wrong blocksize. See if the blocksize is set correctly:
$ mt status 2
tape capacity : 1953251 KB remaining : 1953251 KB
current block : 0 write protected : no datcompression : on
min block size : 1 max block size : 65536
def block size : 16384 cur block size : 512
report setmarks : on
Then try using the correct fixed blocksize if you know it:
mt selblk 5120
Or variable blocksize for reading if you don't know the blocksize
used for writing the tape:
mt setblk 0
