I believe on CDRW's you have to reformat every time you backthem up. They have multiple uses, but not multiple file copying. You cna add to a CDRW, but you can not overwrite without going through the whole disk again. So, if you want to add a newer updated session to an RW, stick in a new CDRW, or reformat your old CDRW.
