Because moving files can fail, you would copy them so you have a second chance.
I can't tell how you created said DVD so recovery is too much guesswork. It's not a Windows issue IMO so let's here more and I'll note ISOBUSTER for you to read about.
I keep getting this message: Windows Can't Read Disk in Drive E:\. This applies to both CD and DVD drives.
I was transferring pictures to a DVD until it had no more room. When I changed discs, the machine said it couldn't "read " the disc. Same situation for both drives. I've changed discs and ran a system restore to no avail.
Outside of waiting for Windows 10, what is the solution for this?
