After backing up files to the CD I found that all the files in the hard disc
files had become corrupted and unable to read by the relevent program (Word,
Excel, JPEG, pdf). It must have happened part way through writing to the CD
since some files on the CD were ok (and could be written back to the hard
disc in theirm original form )but the rest were corrupted.

Any ideas on what could have happened, and, importantly, how to recover the
damaged files. I've tried Chkdsk with no luck.

This is the best there is for CD/DVD data recovery. If IsoBuster can't do it, it can't be done.


IsoBuster 2.5 Freeware/$30

Thanks for the tip, but the files appear to have been encoded into some
unrecognisable file type. Presumably they could be translated back again,
unless they're now just gibberish.

A few details would help. What system - home, pro, ME? What SP
level? What tool did you use to build the CD?
