(Well, i can't parse the above sentence really, but hope to have figured out what it meant. :) Drivers are expected to reject requests that don't match the underlying physical device anyway. IMHO, all (most ?) of our drivers do this already. That's why people see an EINVAL when trying to disklabel a 2048-byte sectored MO media (the label is attempted to be read/written with a granularity of 512 bytes). (General consensus) > though I'd like to leave the b_pblkno, or maybe make it a b_poffset. What for? Hmm, maybe. Slices are evil. :-) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
