I have a lot of photos I have copied to CDROM, starting about 2 years ago. I've now filled my hard drive with photos and need to delete old photos which are on CDROM.

Before I delete photos, I want to make sure the CDROMs are error free. I used to have a free Windows 98 program that would do the scan, but I can't find it any more. Is anyone aware of a free program to do this scan? I searched Google but my search terms are way too generic (cdrtest, cdrscan, cdrom error scan, etc)

I did try writing a simple program for Linux that just read data off teh CDROM until I got an error. One CD was fine, a scan on a second one reported an error about halfway thru and a scan of a third got partway thru before some error occured that resulted in the scan process hanging and non-killable. I suspect kernerl error recovery code got lost somewhere, or an interrupt never came back for a read.

So, I'm not very confident of the reliabilty of my older CDROMs. I also don't consider hard drives as a reliable media to back up files to for an extended period of time.

Any suggestions?

Thanks
