Roxio Help files and Wizard should explain how to record (including the various ways)
Only re-writable disks should be formated at all.
When you copy a file back to the HD the file and any changes can only be saved on the HD itself.
A work-around to put updated files on a CD is to use either a CDRW disk, or to keep piling the altered files as extra sessions on a "multisession" arrangement with an ordinary (write once) CD.
Unlike the CDRW disk you cannot erase old files on a normal blank, but they can be made to 'disappear' when their index is brought up to date in another session. Ultimately this type of CD becomes full.
A good quality blank CDR (in my opinion) beats the more expensive CDRW for longevity and reliability and are relatively very cheap.
