Ok, here's the deal. I was burning a dvd-rw with nero, and halfway through, I realized I was missing some files in the compilation and cancelled the burning proces.
I corrected my mistake and tried burning the dvd-rw again, but some weird error message pops up about the dvd-rw already being written upon. So I tried again with a completely empty dvd-rw and got the same error message.
I tried checking the Properties of the drive and noticed that the drive was showing up in explorer as a CD-ROM-drive. Weird thing is, it can still read, but it can't write because of the error message. The error message keeps popping up, regardless of the dvd-rw, so i've ruled out the fact that's it's a problem with the dvd-rw.
Any ideas? Thanks in advance.
