sg3_utils is a package of command line utilities for sending SCSI commands to devices. This package targets the lk 2.6 and lk 2.4 series. In the lk 2.6 series these utilities (except sgp_dd) can be used with any devices that support the SG_IO ioctl.
This version adds sg_format which can format SCSI disks, potentially with a different number of bytes in each block. It can also resize (sometimes called "short stroke") a disk. There are also extensions to the sg_dd utility to use the READ LONG SCSI command on damaged blocks (for a "last resort" media copy).
A tarball, rpm and deb can be found on: http://www.torque.net/sg . For an overview of sg3_utils see this page: http://www.torque.net/sg/u_index.html The sg_dd utility has its own page at: http://www.torque.net/sg/sg_dd.html A changelog can be found at: http://www.torque.net/sg/p/sg3_utils.CHANGELOG
