I just got done reformatting my hard drive, and one of my CDs I offloaded my stuff on seems to have some errors on it that prevent me from copying the data back on to my computer. I can see all of the files, and even open some of them (although it takes a very long time), but I get read errors when I try and copy them over (same when I try to make an image of the CD).

I know back in the day you used to be able to "repair" floppy disks that had this problem (or at least get the computer to pass over the bad data) -- is there any way to do this with a burned CD?

Sounds like CD may have simply been a bad burn or is just to physically damaged. Probably the best thing you could do is try the disc out in a variety of drives/burners. Sometimes one drive will read a damaged disc better than another. It may mean the difference of being able to burn a usable copy,

Yeah, I'm beginning to think it's physically damaged. I've been trying it in a bunch of drives and using a bunch of different burning utilities as well, and I've only managed to extract a small bit of data from it. I was still hoping there would be some kind of program that would allow me to mark the bad sectors as such, though.

Nah, after the session has been burned the data is read-only on a CD - there'd be no way to set certain sectors as bad.

Makes sense. I'm only lucky that the CD didn't contain especially valuable information.

Thanks anyway.

No problem, hope everything works out.
