Pardon for the unhelpful intrusion, but could someone please explain the issue here? I have hopes that one day my Fujitsu MO drive will be able to use 2k-sector media. Is the problem that much of the code calculates size information in sectors, (perhaps for 32-bit length restriction reasons?) and these sizes will not be appropriate for the information stored in them if the sectors themselves are not all the same size? Would it hurt (in a system that wished to use 2k-sector media on at least one drive) to use 2k sectors for all da drives, even if that meant multiple-sector writes were done as one? -- Andrew "The steady state of disks is full." -- Ken Thompson
