I do recall, back in my dim memory, that when I was writing software for 
the DDS, DLT and 8mm drives, that I would turn off all of extra vendor 
features when creating tapes.    There were some interesting differences 
in the DDS1 drives.   And vendor-unique features differed considerably. 
  Some drives, for example, allowed for read-after-write (i.e. rewriting 
of a block), but not all did.


Speaking of tapes, and not wanting to hijack the thread, but does anyone 
here have experience with the Linux ftape (floppy tape) drivers?  I'm 
about to install them on a Debian Woody setup and wonder if there's 
anything that I should be aware of.  I *think* that Woody was the last 
distro before they were dropped altogether.
