| .SH DESCRIPTION |
| .\" Add any additional description here |
| .PP |
| sginfo is a re-porting of the scsiinfo program by Eric Youngdale to |
| use the sg devices (rather than the sd, sr or st block devices). This |
| program outputs "mode sense" information. Amongst other things it outputs |
| the full defect list of a disk (which was truncated at 4096 bytes in |
| the original). With the '-R' option mode page data can be changed |
| (using the SCSI mode select command). |
