Ah, an interesting topic. In short, for audio cds, cdrdao does a nice job.
There used to be some plextor drives that reported anomalies on cds, and
someone wrote a tool that ran on linux and could report this data, called
qpxtool. Those drives also came with similar tools that ran on windows.
Qpxtool also came with a nice data optical disk reader called deadread, or
something similar. dd_rescue also works well. I wouldn't be surprised if
someone much, much more knowlegeable about this gives a much lengthier
reply. I would welcome such information too.

Hi,
The recent thread on AB20 reminded me I have a large pile of CDs from the
1990s
that could do with being imaged and uploaded to archive.org.
What's the best free Unix tool[0] for doing this? Sure, I know about dd and
cdparanoia, but those only extract data and CDDA respectively, and I'd
prefer
produce an actual image complete with TOC, subchannels, etc. To *use* the
data,
I can always transcode from that into something lossier such as FLAC :)
but the
reverse transformation is not possible.
Failing that, I can go off and *write* one, but I'd rather not spend the
effort
if something suitable already exists and has already been well-tested and
confirmed to not make subtle errors in rips.
(Bonus points for tips on how to do the same with Blu-Ray discs, since I
may as
well archive them now rather than leave it until the 2030s.)
[0] I say this otherwise some berk will pipe up with "you can do that with
SuperMegaRipper Pro from Malware Inc. for Windows 9, and it costs just
$299
for a 60 day licence". I'd rather toss the discs in the bin.
