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?

Thanks!

Have you tried to copy the files over via CLI?  If so, what happens?

How? What files? The computer doesn't recognize the filesystem (hence the "1.1 GB Unknown"). It can't read and display to me which files are supposedly on the CD.

OK, we've made some progress.

I had originally booted into a Linux Live CD because I didn't know what was on the CD and wanted to make sure it didn't give me any viruses. And also because in my experience, Linux will often show you useful information when Windows refuses to. So I popped the CD into my Windows PC after failing to make any progress on Linux, and it opened right up!

It shows three images and one PDF. I was able to copy the PDF and two of the images, but the CD seems to get stuck about 50% through with copying the final image.

Windows shows that the contents of the CD take up about 72MB and the filesystem of the CD is UDF. Which all sounds very standard to me.

But I'm having a lot of trouble getting that final image to copy off the CD.
