 # sg3_utils
 
 Collection of Linux utilities for devices that use the SCSI command set.
+Includes utilities to copy data based on "dd" syntax and semantics (called sg_dd, sgp_dd and sgm_dd); check INQUIRY data and VPD pages (sg_inq); check mode and log pages (sginfo, sg_modes and sg_logs); spin up and down disks (sg_start); do self tests (sg_senddiag); and various other functions.
+See the README, ChangeLog and COVERAGE files. Requires the linux kernel 2.4 series or later. In the 2.4 series SCSI generic device names (e.g. /dev/sg0) must be used. In the 2.6 series other device names may be used as well (e.g. /dev/sda).
+
+Warning: Some of these tools access the internals of your system and the incorrect usage of them may render your system inoperable.
