Stefan Hajnoczi aad64f3193 ide: refuse WIN_READ_NATIVE_MAX on empty device ... What is the highest addressable sector on an empty CD-ROM? Nothing is addressable so produce an error. This patch prevents a divide-by-zero in ide_set_sector() since s->sectors and s->heads would be 0. Not to mention that a sector=-1 argument would be nonsense. Note that WIN_READ_NATIVE_MAX can be triggered using hdparm -N 1024 /dev/cdrom. The LBA bit will be set to 1 though, so the only easy way to go down the ide_set_sector() CHS code path which divides by zero is to comment out the s->select & 0x40 case for testing.
