These should get different error statuses - I/O error versus end of
medium ("no space left on device").
Regarding how much is left, I'm not sure that's easily determinable. I
do recall seeing a command to obtain the tape data density (if reported
by the drive), but you would still need to track how much you've written
to figure out the rest. And guess at the compression rate, for
compressing tape drives.
