Tapes do not need to be formatted, though the issue mentioned in the page you indicate can cause problems. I have seen it a lot on DAT (DDS) tapes and never with a DLT. On the DAT tapes, the solutions given on that page have usually not helped for me. But, since I have never had any problem with DLT tapes, I can't say if they might be helpful. You can try writing a block or two to the drive using dd(1). That occasionally helped with the DAT (DDS) tapes. dd count=10 if=/dev/zero of=/dev/nsa0 Seems like it should have a bs=nn in there too, but I can't remember if the default of 512 is OK or not. ////jerry > > Any help is appreciated, > Jaime > > -- > "To affect the quality of the day, that is the highest of arts." -- > Henry David Thoreau > > Tone of voice in email is misunderstood 50% of the time. > Source: http://www.howtoweb.com/cgi-bin/insider.pl?zone=214061 > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
