sg3_utils
\"The Linux sg driver is a upper level SCSI subsystem device driver thatis used primarily to handle devices _not_ covered by the other upperlevel drivers: sd (disks), st (tapes) and sr (CDROMs and DVDs). The sgdriver is used by scanners, cd writers and applications that read cdaudio digitally. Sg can also be used for less usual tasks performed ondisks, tapes and cdroms. Sg is a character device which, in somecontexts, gives it some advantages over sd and sr which are blockdevices.\"
