There was a bug report about this within the last 2 months that was
immediately closed as "Cant Fix". I have experienced this myself. I
had a few original tapes that I set some size other than the default
and those are currently not readable now since I reset the block size
back to default. The difference is between fixed size and variable
size blocks and also even fixed sized blocks of different sizes. I
believe if you used fixed sized blocks (max and min are the same) you
can not change that otherwise the tape drive can not read the new
block size. If you use variable sized blocks (max and min different
sizes) you may be able to extend the max size or reduce the min size
as long as you don't make the max=min.
