NEC 1100a XP explorer issue

Hi all.

I have been reading through the forums for a solution to my problem and although there is something close - it doesn’t give me an answer.

My problem is this. I have a NEC 1100a and a load of DVD+R discs. When I put a disc in the recorder, and run the Nero Info Tool it recognises the disc with no problems. Yet when I go into explorer (in XP) and look at the DVD drive, it shows its size as 0 bytes free and 0 bites used.

If I try to write directly to the disc, it says that I must put a disc in the drive when there is always one in.

I am really stumped and could do with some pointers.
