Hi and Welcome!
Could you please give some more details?
Does this only happen with blank discs, or also with prerecorded discs (including commercially manufactured ones)?
I had disc recognition problems with one of my external drives. The culprit here was a bad power supply unit (perhaps a contact issue only, I don't know). So if the MS fix recommended by Kerry does not work for you, then you might open the case of your computer and connect your drive to another cable from the PSU.
