I just burned a bunch of ISO Data CDRs and when I began inserting them back into the drive to catalog the file information the drive did not recognize any of the discs. Now this has happened to me a few times before so I knew just what to do. I took an ISO Data CDR that I had burned a few years ago (a different brand of CDR) and inserted it into the drive and sure enough it recognized it and opened a new window with all of the folders. After that the drive was able to recognize all of the newly burned discs, and like I said this has happened to me a couple of times before. What's going on here? Is this some sort of irrational computer "buggy" thing or does it mean that these new discs are "bad" burns? Note: This never happens with audio CDs or audio CDRs
Old disc works new disc don't = shit quality on the new disc , you could try dvd drive firmware update however it means any data written to those new discs can't be trusted to last. edit It's also possible your drive is old & having issues with the disc dye
