Format internal tablo hard drive

Not sure how to begin, but thanks for any help i can get. I got a new router and in the process of reconnecting my Tablo 64gb, 2 tuner it deleted what i had saved so now i cant see anything of the recordings i had on the internal storage, but the space is used up and no way to use it. So like i only have half of the storage on the intenal memory, i dont care about whats on there now, i just want the full 64gb back. Any ideas??

You might need to factory reset your Tablo, but before doing that contact Tablo Support - maybe they have a procedure to clear the memory without a reset.

Thank you
