UPDATE: I've come to the conclusion that the CD is corrupt (Cyclic Redundancy Check errors), and have told the owner to try to get a new copy from the original source. Original message below.
Someone handed me a CD, telling me it contains photos of her 5-year old daughter's ballet class. She says her computer won't read it and asked if I could get the photos off of it for her.
When I put it in my computer it tries to read it for several seconds but then gives up. It doesn't show up as having anything inserted in it. Here's the mystery: I opened up the Disk manager to see what it would reveal, and it's showing this:RESOLVED: Please help me figure out this CD
Media: CD-ROM Disc
Size: 1.1GB (1,073,741,312 bytes)
Volumes: 1.1 GB Unknown
The CD itself is labeled as a Philips 700 MB/80 min 52x speed CD-R. I'm sure most of those details about the CD itself are unimportant, but I included them just in case.
So... how can a 700 MB CD have a 1.1 GB partition on it? Is there any way I can salvage the data from the disc, or is it a lost cause? Any suggestions or troubleshooting steps I should take to try to get the disc to read properly?
