thank you.. in fact i need to know 2 things.

1) how to turn off tapesize calculation. i have DDS-2 drive with
compression but dump prompts for next tape after few minutes
2) how to dump all filesystems mentioned in fstab with nonzero dump flag?

3) does dump accesses data through filesystem, cooked device or raw
device. i think raw would be the best. 

does -k 256 or more make sense so no seeks will be made?
