Using ficticious geometry The drive has refused a MODE SENSE command, so it's not possible to establish its geometry. Geometry is only (really) relevant for processing the MBR. Instead, the driver will fake some sensible falues. > sd0: NOT READY asc:3a,0 Medium not present > sd0: could not get size > 0MB (0 512 byte sectors) The driver has attempted to interrogate the drive to obtain its total size in sectors. The drive reports an error because you haven't inserted a disk. This is common for removables, particularly those that support more than one media size. > sd0: with 0 cyls, 64 heads, and an average 32 sectors/track And this is the resultant fake geometry, given a size of 0 sectors.
