I used Nero to burn an image of a floppy diskette onto a CD-RW (I needed it to boot up my laptop when it got screwy, since the laptop has no disk drive), but now I can't erase it in either Nero or using XP's built-in CD-RW support. If you burn an image of a floppy disk onto a CD-RW, is that a permanent burn that can't be erased? If it's not, how can I erase it again? Also, for future reference, is any sort of burn like that -- floppy image, music CD, video CD, i.e. anything besides just a file repository -- a permanent burn, so I shouldn't do that in the future? Thanks in advance.
