Yikes! Did I attach this to your thread or is that just the way it
shows up on my Kmail? I didn't mean to do that.

I tried that, but when I ask tar to access the tape to get a file or
list the archive contents, it reports "Cannot read... Error is not
recoverable. Exiting now."
Apparently tar uses a different format on tape and disk. Also, I
pay the time penalty of writing the disk file then the tape file in
tandem. This isn't such a big problem as to force rescheduling of my
family time, but I thought there might be some more time-efficient
method I was overlooking.
I assumed this was a simple matter of linking some Linux utilities
together - that was 2 days ago.
