Well i wanted to make a music cd last night but when i put it in there was something on my cd-rw so i went to erase it and it took ages it reached 99% then likes windows media player stopped running properly. And in "my computer" it doesn't say "f drive" like before it only says "drive e". What should i do please help! I'ts like it's not even there! I can't make a cd for it because it doesn't detect any device. Help!!!

Reboot your computer, and you'll see the f drive again
and of course, the f drive may probably disappear again sometimes when it happened once!
