File system error 608? huh?

When I insert a CD-RW disk into my LTR-40125W, after having just written to a CD-RW disk, the new disk refuses to be recognized and I get the error “CD-RW drive: W:\ is not accessible. File system error (608).” (where “W:” is my CD-RW drive letter). I’ve searched the 'net but can’t find any answers to what is happening and how to correct it. Does anyone know what causes my CD-RW drive from not being able to read a newly-inserted CD-RW disk after reading/writing to one? Thanks!:eek:
