The pictures are on a hard CD disk. I cannot see the pictures even though I know they are on the disk. I have been through this before, only I have forgotten how I did it. I might have been under sea princess exp pro at the time.
Obviously make sure the disk is clean. Try it in a different CD Drive, some drives don`t recognise certain manufacturers media. You could also try cleaning the CD Drive in case the laser has collected some dust. Can you see anything on this disc and is it a CD-R or rewritable?
If Taff's advice doesn't work, then maybe Isobuster could get in. I used it this week to access data on a DVD that refused to load into two different drives. There are some free or trial versions available if you Google it.
