I have Dell Laptop with Sonic Record Now. Having trouble with adding to a disc that already has data on.
(CD-RW). A message pop's up "The disc you have inserted is not blank. Would you like to erase it now" On my Desktop computer I can R click and send to, CD Drive? Can you help me solve my problem. Foreveryoung.

An RW disk needs to be packet formatted to allow it to act as RW disk. If it was not packet formatted, then its being treatred as a CD/R disk. Unless the previous write was done as a multi session you can't add to it.

Many thanks Scott. This seems very feasible, because the disc was written.
