I had (well, still have) a DVD+R which I recorded. For a few years now it has been working without issues. When I tried it the other day, I couldn't read it, Windows couldn't even get a "start up" reading where it shows you the name of the disc, and the files on it.
I thought maybe the drive failed, or the lens is dirty but other CDs/DVDs work fine. I tried reading it on two other laptops, alas, with no success.
The disc has no scratches that I can see, while some of the other ones are scratched all over and work without problems.
Do you have any ideas what could be wrong with it and how could I go about getting my data back from it?
