Maximum mounts reached error 96

Friends,

Duplication jobs to tapes are failing with an error 96 unable to allocate new media even though there are plenty of scratch tapes in the library. Did some troubleshooting and noticed their maximum mounts (200) have been reached hence error 96. so couple of solution that come to my mind are:

a: reset the maximum mount number?

b: delete all those tapes from the database as they are scratch and readd and relabel them?

any other suggestions would be appreciated.
