Here's the log message: Aug 11 00:18:09 moon st0: MEDIUM ERROR info:0x5f000 asc:c,0 Write error sks:80,1 Aug 11 00:18:09 moon st0: MEDIUM ERROR info:0x1 asc:c,0 Write error The same error seems to occur every time, even though the tape was changed out (twice). > > The fact that it listed the files doesn't mean that they got written. > tar first blocks them, and then tries to write the blocks to tape. > > > I'm doing this as root.

What happens if you don't set a density > at all? I've set the density on /dev/st0ctl.0, to serve as a default on rst0. I don't set density in the tar command (I don't think I can). I've tried blocksizes of variable, 512, and 8192, and a couple different densities. Seeing as how the densities and blocksizes are defaulting, I don't see what "What happens if you don't set a density at all" could mean to me. I use as tar command "tar cvfb chuckr b #" (#=blocksize, or omitted for variable size blocks). chuckr is my home dir. > > Greg > -- > See complete headers for address and phone numbers > finger grog@lemis.com for PGP public key > > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@glue.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic (FreeBSD-current) (301) 220-2114 | and jaunt (NetBSD). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
