Thanks very much Aaron. Unless the whole live CD loads into RAM, I would have had a problem using the CD drive. Duh! Hope to have time later today to try this out.

Yes, that's right.  The resulting images should work under Windows in most disc-burning programs that can work from image files (that is, most of them).

Sorry, I should have specified that the original program was for Linux, but since the request was from a Mac user, I didn't want to go too far off into the weeds with an explanation of why there wasn't a Windows .exe available.  We're talking about the difference between a full-size pickup truck (or maybe an armored vehicle) and the family sedan.  Different tools for different purposes.

Yeah, basically that's what I'd do.  The nice thing about these Linux tools is that they run easily from a live CD or USB drive.  In this case you'd need to do a live USB, since your CD/DVD drive will obviously be occupied (unless you have two).

For making the live USB I would suggest Universal Boot Installer, which is a Windows program:

Note that your computer must have USB booting enabled.  Instructions for that are at the bottom of this page:

Then follow the instructions for Steps 2-5 on the link Carl gave, only you want to identify your CD/DVD drive and not your hard disk, and run ddrescue on that.

STANDARD WARNING: The programs included in something like UBCD are powerful, potentially dangerous tools.  They won't do anything you don't tell them to, but if you muck around in the wrong places you can lose a finger, or an eye, or the contents of your hard drive.  If you follow the directions and double-check your work before hitting enter, though, you will be fine.

And yeah, it's a little geeky -- this is data forensics we're talking about, after all -- but it's certainly possible.  It's not something you want to do every day, and it may not be something you want to do at all, but I provide this information mostly so that folks know there is an option out there to at least try to recover your data, short of sending it out to specialists (who use some of these same tools).  It's up to you whether the data in question is worth the extra time and effort.

It sounds to me like that's pretty much what it's doing.  If so, it was really smart of someone to build that in.
