Any tape drive that uses standard SCSI as does the 'Ultrium' will work just fine. I have used DDS, DLT and LTO with no problem. I am assuming by Ultrium you mean the HP LTO drives. They read and wrote very fast and seemed reliable, but didn't seem to have the high speed file seek ability of the others. Seeks (eg mt fsf nn) down the tape took almost as long as just reading the tape. That seemed strange to me. I have not tried the hardware compression. I assume it works on LTO as well as any of the other format drives. ////jerry > > Thanks, > > > Jay > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
