The two marked sections lead me to tape block size problems.
The first probably means either variable sized or default size.
The second I think is coming from a dd command. dd gives a funky
message like that if told to read a tape with a larger block size
than it has prepared for (either default 512 bytes or the value
of the bs= option).
Does your mt or other command let you set up the block size on the tape drive?
If so, set it to 32KB
If not, before doing an amlabel, with the tape you want to label positioned
at BOT, pick a big source file like /bin/sh or /bin/perl, and run a command like:
dd if=/bin/sh of=<your tape drive> bs=32k
That should write a number of 32KB blocks to the tape and when read by amlabel,
should force the drive to 32KB size blocking.
All this of course is guess work.
