Apparently, the 8500 series Exabyte drives will default to 8500 mode
(high density), but only if you start from the LBOT (Logical Beginning
Of Tape). If you don't, and the tape has already been written on in
low-density (8200) mode, then the drive will silently keep on writing
in the low density. We might want to keep this in mind when we're
dealing with backups, and this might very well explain why fms was
reporting something around 2 gig. If people are interested, I can
attempt to apply a kernel patch which will allow you to select tape
density via choosing which special file to write to...
