Well, I'm leaving it as /dev/nsa0 since that appears to be the correct device. Now I'm a bit confused. I tried cleaning the drive (just did it last month, but can't hurt to do it again), but still got that same error. Put a brand new tape in and voila, that worked. So how many of my existing 15 tapes will need to be replaced? How many times do you generally use each tape (rough number)? I bet there's not much of a difference between DDS3 and DDS4 tapes as far as useful duration. The one I replaced had been used 17 times over the last year or so, but some of the other ones have even more, but I've never had any tape errors, so I figured they were okay (uh-oh I can see that assumption biting me!). Perhaps the FreeBSD tape driver is a bit more sensitive about tape errors. > > > DUMP: Dumping /etc to /dev/nsa0 > > DUMP: bad sblock magic number > > DUMP: The ENTIRE dump is aborted. > > Bad sblock magic number?
