I've gotten into the habit of backing up my CDs as ISO files, just in case the discs should be damanged, lost, or destroyed. Using InfraRecorder, the process is pretty painless.

Unfortunately, I have run into at least two discs that don't back up. I get the error message: Can't read source disc. Retrying from sector 252270

Sometimes this will appear repeatedly. One of the discs is my retail copy of Star Trek: Armada II; the other is disc one of DOOM 3. Both discs run flawlessly when I put them in the drive and let Windows AutoPlay them.

Armada II appears as two tracks (one data, one audio) in InfraRecorder, and the error happens at the approximate track boundary. DOOM 3's first disc, however, fails much sooner (around sector 990) and appears as one solid data track.

Am I simply using the wrong tools for this job? InfraRecorder is a nice free tool that I can run from my flash drive and use for most tasks of this type, but it does seem to have trouble with certain things.

Ideally I'd like to hear about any workarounds people have found for this issue, but if I must switch tools I'm open to it (preferably other free tools).
