Hello, I have a LG 24x10x40x a MITSHUBISHI 650MB CD-RW. I tried to erase the existing contents of this CD-RW. In Windows Explorer, I right clicked on the CD-RW drive and choose erase this CD-RW. It works like normal, a bar notifies percentage of the work. Finally, it said all done. However, the problem is my CD-RW is actually not erased at all. The existing content is still there. This should not be the CD-RW disk problem, because I have tried different brand of disk. and all 650MB CD-RW disk cann't be erased properly. The strange thing is while I tried to erase the content in a Verbatim Pocket CD-RW 185MB, it works! I dunno what happens. Please advice. thank you.
