I am curious to find out if I change the block size will I be able to go back
and restore data from tapes that has the old block size?
Thanks,
URao

Did you attempt to mix blocksizes on the same physical tape?
That will not work. If you change block sizes all existing tapes holding data
must be marked "used" and new ones labelled.
I run 2Mb block size quite happily on HP LTO5 drives and have done for a few
years. They are capable of 16Mb - we are limited to 2Mb by Bacula.
