We needed a bigger tape, so we got a 20gb one, but it still thinks it is 10gb. it doesn't say on the tape that its 10/20 gb or anything like other threads have described. Running identify on the tape shows it to be 10gb, but it is supposed to be 20gb. What can we do?? ![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
