Then try "mt retension", "mt rewind", etc (see "man mt"). Does a Travan tape require formatting? Would the tape drive report empty if the tape was not formatted? Tapes used in most Unix systems, such as DAT, 8mm, and QIC-150, don't require formatting. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
