First, what it means: the driver wants a write length which is a multiple of 512 bytes. That works well enough with tar normally, but not if you compress, in which case it writes in dribs and drabs. You can fix it with: tar czf - <files> | dd obs=20b of=/dev/rst0 This will force a block size of 20 blocks. Greg
