The problem may be to do with your SCSI adaptor or the drive itself; I
have been successfully reading and writing 128K blocks on an HP C1599a via
an Adaptec 2940 without difficulty (other than a hardware fault in the
drive itself) and without modifying the 2.0.32 kernel I've been using.
I use large blocks to maximise tape capacity by reducing the number of
interblock gaps and giving the on-drive compression a fair size chunk of
data to compress, which I believe more likely to yield good compression
ratios than small blocks.
