Pretty much all SCSI-based tape drives work just fine with the normal st device; and yes, one can use "mt comp" command to enable or disable the built-in hardware compression. However, most tape drives default to enabling their preferred compression algorithm already, so you most likely won't need to do anything special except run tar, dump, or whatever to actually write data to the tape... Ultrium/LTO is a pretty good form-factor-- certainly better than the helical-scan 4mm DDS systems, but I have a mild preference for (s)DLT. -- -Chuck
