Don't use d and s. Use b for the intented block size (it's important for variable-length capable drives like DAT and QIC >= 525 to use the same block size for writing and reading the tape), e.g. 16 (stands for 16 KB). Then use B to tell about the entire tape length, in your case 16000000. Everything inside dump/restore is measured in so-called "tape blocks" of 1 KB each. dump 0ubBf 16 16000000 /dev/rst0 usr -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
