The Toshiba SD-R5002 CD/DVD-RW that came in my Sony VAIO desktop is no longer recognized as a recordable device. It was working fine and I don't know what's changed. The machine has XP Home Edition and came with EasyCD Creator. Blank DVD's are recognized and bring up the CD writer software. The message I get in EasyCD is "no compatible recordable or rewritable devices could be found on your system". I get a similar message in Windows Media Player. The properties say it is functioning fine, and it reads CD's and DVD's pefectly. Any ideas?
