thats not true when u are using windows 7 this was taken from microsoft.com

Be able to add and erase files over and over, as if the disc were a floppy disk or USB flash drive


Disc: CD-R, CD+R, CD-RW, DVD-R, DVD+R, DVD-RW, DVD+RW, or DVD-RAM.

Format: Live File System

You can burn files to a DVD-R more than once (each time is referred to as a session), but you can't delete files from the disc. Each burn is permanent. from microsoft.com ner ner
Which CD or DVD format should I use?
