for me.
Is there
anybody on this list who knows a way of recovering flaky CDs?
Easiest first step is
try using different kinds of CD/CD-R/DVD-R drives.
I have found some 'unreadable' CDs could be read using a DVD drive.

A great problem I had some time ago was a sort of oxydation of the
cd material; this seem to happen using very bad cd brands. i had
this horrible problems with "SEANTRAM" and "PRINCO" cd's; the
princo cd was literally unreadable after only 6 months of age!

Note that the reflecting layer in factory produced CDs is aluminium.
A thin layer of lacquer is protecting the reflector.
As an interesting eye opening experiment I dumped one of these AOL promo CDs
we used to be bombarded with in a bowl of lukewarm water. Plain water, 25
degrC. Within a day the aluminium layer had holes in it the size of dimes.
Apparantly the protective lacquer was very substandard.
El-cheapo CDR can have similar characteristics.

not similar programs for data disks?

Dont know how true it is but the local paper here was running a story
about some students using goverment condoms to fix scratched cd's. They
worked for 3 uses. Never tried it as most of the stuff i have on cd i
can get again.

Ignoring the inevitable ribald humour arising from the concept - "supersized,
for all the government d*ckheads" ... ;)
A friend of mine suggested using a silver polisher to resurface the plastic
when the scratches prevent it from being readable, but I've never tried it.
