Linux supports both types of block sizes. 'mt status' should tell you what
the 'tape blocksize' is set to. If it is set to a fixed number (usually
512), then everything is written in blocks of that size, and the block size
on output is arbitrary.
If the blocksize is zero, then the tape driver uses the blocks that are
written.
mt setblk 0
will give you the conventional blocks size.
BTW, this isn't any different than how the Solaris god does things.
