Note that I've seen QIC tapes fail fairly rapidly if not stored fully rewound; the tension pulls the tape over the index holes and causes the layer or two immediately above the holes to deform, making several sets of tracks unreadable at that point. Aside from that, I tend to concur; if you want the data to last any length of time, 9-track or QIC is about the best you'll manage. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
