(Naviant? Hmmm, maybe a fellow ex-MRJ co-employee....???) > (sa0:sym0:0:5:0): extraneous data discarded. is a bit of a clue... Make sure that you've set the tape to variable record mode- do an 'mt status' to see what it's set to, and set recordsize to '0'. When you do tape stuff with FreeBSD, it's often best to get a bit more data than that which you have reported here. btw- do you *really* want 32619 byte output records? > OK, I admit that this may be user error, and if not it's probably not an > item for this list, but here goes: > > Synopsis: > 4.2-RELEASE on i386 > Symbios 53c875 HBA > IBM 3490E/F01 deskside changer > read from tape is fine, write to tape fails with I/O error from sa0.
