Fred, I came across this interesting freeware which your readers may find helpful: Roadkil’s Unstoppable Copier.
The author writes: "This program is great for recovering files from scratched CDs or defective floppy/hard disks. Normally when your computer is unable to copy a file from a damaged disk it will abort and delete the portion of the file it has copied. This program however will continue to copy the file right to the end. Any data that is not recoverable after many retries is replaced with blanks. This will allow you to truly recover every byte of information that is available for recovery. The program allows you to specify a single file, a group using wildcards (* and ?) or if you wish, select a starting folder and the program will copy all data from it and any sub folders it may contain. This program doesn’t just need to be used for copying files form defective disks, it can be used to transfer any files!"

Thanks, Bruce. That could be a lifesaver!...
