If anyone has any suggestions for how to clean CDs to recover data,
I'm all ears.
Do you have access to a Record Store that deals in used CDs? I know
one of our local ones used to have a machine for resurfacing CDs, at
the time, I didn’t need to make use of the service. Another option
might be used Video Game stores.
Thanks for that, I didn't realise that such a service even existed.
There's a GAME in the Westgate in Oxford and the GAME website mentions
CD cleaning for games, so I might call and check to see if they have the
machine. £3 per disc, so it perhaps might be worth trying on one. When I
hold the CD up to the light there are definite pin pricks where I can
see the light shining through so I rather suspect that there are some
points that are unrecoverable. So maybe not.
I also happened across two youtube videos
(https://www.youtube.com/watch?v=Tpcd-5fd9nY and
https://www.youtube.com/watch?v=TNV7mDfWuWI) where people do the same
sort of thing by hand. I happen to have some 3000 grit wet-and-dry
available. I might have a go at that too, although I think I should find
a data CD that I don't care about, rough it up and see if I can "unrough
it up". Pity I threw away all those AOL CDs years ago :-) Actually, I
suspect I have a number of duplicate MSDN CDs, so those might do for
experimentation.
So far I've just tried using dd to recover the data but perhaps I should
try to find something that won't give up when the OS reports an
unreadable sector. Anyone have any suggestions?
Thanks
Antonio
