If you recovered data, but it isn't usable, then the recovery failed. You may need to try a service like drivesavers.com or ontrack.com They do CD recover too.
A couple of questions.
Does anyone know of a good data recovery software for CD-R's?
Also, I recovered data from my hard drive however I cannot open certain Word Docs, pictures, *.ZIP files.
Anything you can think will be really appreciated.
