ISOBuster will recover just about anything from a CD disc.

As others have said, CD-Rs can't be overwritten but if you use a disc that has been formatted in UDF format for drag and drop burning, I have seen it happen dozens of times where writing a new session can mess up the TOC and previously written data disappears. The program I listed is great for recovering data from such errors. The data hasn't been overwritten, the TOC (Table Of Contents) on the CD has been corrupted.

This may help.

Easus gets generally good reviews here; and I have recently tested it and found it OK; albeit only with a hard drive.

Lesson for the future...

Make two copies of photos; store one well marked - do not overwrite...; end even better use CDR for at least one copy - and check copies (whichever they be be) regularly.

"Photos saved to CD-R in error overwriting the original data"
You shouldn't be able to overwrite on a CD-R.

Are you sure you are looking in the original disk?

Oops misread disk type. Yup CD-R can’t normally be overwritten

As stated above a CD-r can't be overwritten. What can be done is this. If you try saving additional files with the same names you will be asked if you want to replace the original files. If that was done then the original files are flagged as if they were erased.

That said, what probably happened in your case is that you didn't finalize the session or disk, as the case may be. Check out some of the threads linked below. If you don't write anything more to the disk you can't destroy what is already there unless you physically damage the disk itself.

Sorry to be generic with this answer but you haven't supplied enough information yet to know the exact issue. Reading some linked threads will give you some incite.
