I am tryin to read data from a NetBackup tape.

I can read the first block which is 1024 bytes, the following file mark and then the next block (again 1024 bytes) after that the block size is 262144 bytes and when I try and read 262144 bytes varibale from these blocksI the SCSI command hangs.

I am obviously using variable block sizes.

If I read just one byte from each block then the ILI correctly reports the difference between the bytes I have read and the block size.

The problem seems to be that the MaximumBlockSize as returned hy GET_TAPE_DRIVE_INFORMATION is 64K - is there a way of changing this (XP Pro) or am I missing something?
