If you have a second CD or DVD drive, try that. Unfortunately, I haven't
had a single version of Windows that will handle an unreadable or marginal
CD well...even the ctrl-alt-del combo doesn't always work. I've always
wished for a simple way to tell it to stop trying to read the CD, now,
immediately.
Your CD drive may not read all CDR's well, the CD quality of burn may be
marginal, or there may be dust inside the CD drive.
At any rate, I'd try other CD drives, on different computers if you need to.
If every other CD drive except yours reads the disc OK, then you can assume
the CD is OK and your drive has a problem. Often a good CD-RW drive will
have the best chance of reading it. When you find one that reads it, I'd
suggest copying the files right away, either to the hard drive, or burn
another CD (if it's a CD-RW you're using to read it, you can have it use the
hard drive to temporarily store the disk image until you insert a blank CD.
I'd suggest using a normal CD writing program like Nero, EZCD Creator, etc.,
and have it verify the files, rather than a packet writing program where
you just drag the files to the CD drive (Direct CD, etc.). While I don't
mind using packet writing programs for unimportant stuff, archiving photos
to CD needs to be done right, and there are too many things that can go
wrong with packet writing software (I won't even install one, they cause
other problems also, such as with DVD burning programs).
For any photos that are important at all, I wouldn't erase them from the
hard drive until you have two copies on CDR or DVD-R; and even then, might
as well leave them on the hard drive also, unless you're short on space.
If you can't get anything to read and open the files, ISO Buster may be able
to rescue them
