there are different implementations of the mt utlitiy. On my Debian 3.0 system I find: - GNU mt version 2.4.2 from the cpio package: "... This package also includes rmt, the remote tape server, and GNU mt, a tape drive control program. The mt program is essential for magnetic tape drive users. Debian's version of GNU mt supports SCSI tape drives." and - mt-st v. 0.7, package mt-st: "Linux SCSI tape driver aware magnetic tape control (aka. mt) Mt-st contains a version of "mt" that is aware of Linux's SCSI tape driver. Mt-st is able to set some esoteric control flags like tape partitions. Mt-st diverts (replaces) the GNU version of mt, in the cpio package. It also comes with stinit, a program to be run at boot time to set up tape defaults." The GNU mt manpage mentions the datcompression operation, while mt-st knows about compression and defcompression (default compression state). Greetings, Martin
