data recovery from degraded cds

I’m trying to recover data (jpgs mostly) from ~8 yr old CDR’s that have
apparently degraded. Trying to mount them I get a
Hal.Device.Volume.UnknownFailure: error on 2 different computers. Can
anyone recommend a technique or app to pull whatever data is salvageable
off of them? I’m new to OpenSUSE but not to Linux in general and I
don’t mind getting down to the terminal or compiling apps so it doesn’t
have to be point and click. Thanks!
Leo

You could try to copy off the image to ISO files using ddrescue (search
for it), and then do whatever forensics are needed on the ISO file. It’s
pretty grim though if the directory on the CD is not readable.

You could try photorec. I’ve used it to successfully recover
accidentally deleted photos from my harddrive.
This is the description from the photorec man page.
“PhotoRec is file data recovery software designed to recover lost
files including video,
documents and archives from Hard Disks and CDRom and lost
pictures (Photo Recovery) from digi‐
tal camera memory. PhotoRec ignores the filesystem and goes
after the underlying data, so
it’ll work even if your media’s filesystem is severely damaged
or formatted. PhotoRec is safe
to use, it will never attempt to write to the drive or memory
support you are about to recover
lost data from.”

I recommend a look at dvdisaster. It’s a complete toolset to recover and
protect cds/dvds and has a nice gui (if you can stand not getting your
hands dirty at the terminal ;))
