That thread talks about a situation where the drive cannot even detect the presence of a disk, because the reader is dirty and needs cleaning. But OP's post looks more like he / she expects the drive to "read" a blank new disk. That will not happen, because there is NO information on the new disk to read. It does not come "pre-formatted" like old floppy disks did. If you are using software to "burn" a new disk, it should be able to tell you that the drive unit does contain a blank disk. But you can't read anything from it until data is stored on it.

I've found that "lately" my drives have gotten "tired" of certain brands of discs, and after research and testing have found others that work just fine! But either they are changing the "Quality Control" at almost every manufacturer ( because numerous of my computers recently same thing) or our drives are getting "finicky" with age. Try a different brand and see. Good disc, uh, Good luck. Memory Maker Santa Rosa, Ca.
