I suspect that you are using tar from the Rootdisk. (Linked to pax.)
The problem is that the PAX is expecting a certain signal to signal
the end of a diskette (ENOSP?). This is not getting sent, and so it sits,
trying to write to the diskette, getting 0 back from write, but ignoring
this.... forever. I have a fix around here, somewhere, but not
here right now. If people decide that they want to be perverse about it,
and not use floptools, I can hunt up the patch. I have told Jim
Winstead about it, but lacked the confidence that I had the source
of the problem understood to decide that it was a problem with the
floppy driver (ie kernel), to actually send in a bug report, so I passed
the buck to someone who I perceive as more knowledgable than I. I then
decided it was taken care of, and left it. Is it?
