That's probably a problem with the EOF (on write) handling in the sd
driver.  I remember that i've been fixing a similar problem in the fd
driver very recently -- it used to be there for years now!

You should always be able to get it working correctly by also
specifying the -L kilobytes option to tar -M.  You most likely also
need it to read the archive back, however.

Are your problems with the multi-volume tar files accompanied by some
SCSI error messages in syslog when you hit the end of a medium?
