1. [OT] scratched CDs
Should probably have made this "off topic" in the first place, sorry.

Chris, I tried it, but its "recovery" of the scratched track was WORSE than
the original, and the "surface scan" reported NO errors, said the disk
was fine. Maybe it's an interaction between the program and my cd player.
Anyway, thanks for trying, I'll go back to visually inspecting the disks
and crossing my fingers & notifying the library about them.

You might try 'Exact Audio Copy'
http://www.exactaudiocopy.de/
A different CD-ROM drive might also give a better result, too. Or a worse one.

Hi
AFAIK, the units of storage on a CD is a sector. Perhaps you could read
sector for sector, and replace bad sectors with blanks during the copy?
Maybe Ralph Brown's interrupt list would help for that:

This may or may not work, but I had a bunch of really scratched music cd's
that wouldn't play right in my car cd player. I purchased a polisher unit (I
think I got it at Walmart about $18, but you could probably get one online) and
it restored them to perfect health! Don't know if it would work in your case,
but
it only take a couple minutes to polish the disk. Worth a shot.

Hello everone,
First try liquid dish soap, rinse with cold water, shake do not use paper towel.
Next try a piece of valour on a dry CD.
Third there are testers up to $2299.
Check out Dr. Clean below($23.95).

All,
I want to thank AndyS, Gary, ChrisBu & Don & John & Alan & Rich for their
varied suggestions. Unfortunately, the software didn't pan out, & I wouldn't
want to use any of the "fix the disk" ideas because they're not mine, they're
from a library.
"IsoBuster" looked like maybe the best bet to SPOT errors, which is what
I wanted to do, but it gave the bad disk a completely good bill of health.
Dunno why, maybe I'll ask the author.
BTW, I did find an "archivist" on the web who said NEVER use any WATER,
as it will soak into the plastic & ruin the data substrate, but
that's long term; if it works to get data out to a new copy, I'd think that
should be fine for most people.
Polishing seemed to get the most favorable reviews from others
with scratched disks, though there were some "spray-on"
repair ideas that some found phenomenally good, even on NEW disks, to bring
out highest sound quality.
thanks again all for the suggestions.
