Waraich) Newsgroups: comp.unix.bsd.freebsd.misc Subject: TDC 4200 and FreeBSD Date: 29 Oct 1995 01:17:07 -0400 Organization: LInet, Long Island NY Lines: 45 Message-ID: <46v2oj$kd1@linet04.li.net> NNTP-Posting-Host: linet04.li.net I am trying to use a 2GB QIC tape drive, (Tandberg 4200) with FreeBSD-current and I was wondering if someone could help me with some problems that I've been having. 1) dump(8) runs out of tape very quickly. I can't dump a 250 meg partition even on three (150m) tapes. However I'm sure this is not a problem related to my tape drive but rather concerns dump itself. Somehow I need to tell it what kind of tape/drive I'm dumping on. 2) dump-ing to stdout and then piping it to dd works, but I use up almost twice as much tape (which might mean that dump might not be a culprit in (1)). My root partition is about 20 meg and I can dump it 3 times before running out of a 150 Meg tape. 3) After dumping as mentioned in (2), when I go back to beginning of the tape, I can read the table of contents of the first dump. But if I type this: mt rew mt fsf 1 restore tf /dev/nrst0 I still get the TOC for the first dump. Whereas if I do this: mt rew dd if=/dev/nrst0 of=/dev/null (to skip one file) restore tf /dev/nrst0 I am able to get the TOC for the second archive. 4) And then ther are times when after writing a dump, I go back to the beginning of the tape and try to get a TOC or to read the file and get absolutely nothing. Can anyone explain to me what I'm doing wrong ? Or is there a problem with the driver or drive ? One more thing: 'mt status' returns default density as 0x0. I'd apprecaiate any help. Saad
