I use DVD+RW's on a daily basis -- writing, erasing, and rewriting. However, recently, the "erase this disk" option in File Explorer is greyed out.

The first time it happened, having failed to find a solution online, I restored my C: partion, which fixed the problem, but is a bit heavy handed.

It's happened again today. I can erase the disk using CDBurnerXP, but that's an extra step which I would like to avoid. It affects all disks, so it's not caused by a faulty disk.

I would appreciate any suggestions for how "erase this disk" could be brought back to life.
