I purchased a Dell Studio in Feb. Had no problem writing CDs on the DVD/CD writer until last week. Having the same problem as posted by Hartings. Burn seems to work until message "performing final steps". Then get the error buring the CD and CD might be unusable. I also have Roxio DE Creator 10.2 (came installed) but have used it to burn audio CDs for some time. Tried several CDs, including trying to add file to a previously burned Disc but got same error. Avbove error occurs in Microsoft CD burning program. Get similar error in Roxio. OS is Vista Home Version which came installed. All help is greatly appreciated.
