Recently invested in some dvd-rw. After using it once, I don't find an option to format for my drive in Windows XP home. I can erase. Nero 7 erases it more, which takes about 15 minutes. Then My Computer still reports that the drive is 0 bytes free space and 0 bytes used space. I am expecting to have the 4.7 GB there and the pink picture. When you try to copy even a little file on it, it won't let you. However, when I used my movie converter, it put the converted movie on it with no problem. Strange. Can anyone explain this?
