Let's assume your Block Device is an ATA Hard Disk and you're using FreeBSD 6.0 like me. Take a look at <sys/ata.h> and you'll see a large fully-commented structure, "struct ata_params", which is used to return the information from the ATA "IDENTIFY DEVICE" command using something like: "ioctl(DevFil,IOCATAGPARM,&Parms);" This probably tells you everything you need. Plus IOCATAGPARM also returns CD/DVD Drive information using the related IDENTIFY PACKET DEVICE command. For further details consult the T13 Website. For ATA/ATAPI you might start with: "T13 1153D Revision 18" "Information Technology - AT Attachment with Packet Interface Extension (ATA/ATAPI-4)". Though there are later versions: "T13 1321D" (ATA/ATAPI-5) and "T13 1410D" (ATA/ATAPI-6). Whatever device you have there's probably some Hardware Command which gives you all the technical details.
