The following shows that a MTBSF request did not move the tape.
Use the bsd device, that is /dev/rmt/*b
1. create data on tape from BOT:
3 blocks, TM, 10 * (10 blocks, TM), TM, 2 blocks
2. seek to logical block 70
3. do MTFSF 4 files - this should be positioned between 2 consecutive tapemarks.
4. read 1 block - this should hit tapemark and positioned after it because
we are using BSD.
use MTTELL to get the current logical block count.
5. Do MTBSF 1 file - this should have positioned 1 block back. So the logical
block count should be 1 less than the logical block in step 4.
6. However, the logical block count after sep 5 is done is the same as that from
step 4.
I am attaching a program that shows the problem.
