No.
Filling tapes aren't eligible for reclamation, unless they are marked
OFFSITE.

If the tape is filling and onsite, the %utilized is the estimated amount of
tape that has been used (the number of bytes written as a percentage of
Est-capacity for the devclass)  and the %reclaimable is the amount of data
on the tape that has already expired.

One the tape is FULL or OFFSITE, %utilized is (100% of the bytes actually
written to the tape) -(the amount of data that has expired).
