Best program to copy a "damaged" disc?

[aakerman]

I'm trying to copy some DVD discs (with data, not movies) to my hard drive, that I borrowed from a friend of mine. I get to the middle/two-thirds of them about, then I get an error saying "Cyclic redundancy check".

There are no visible scratches on the discs, they are in perfect condition - and not more than 2 months old either. Which program can I use to retrieve the data?

I have tried Alcohol120%, but that gave an error too.

I don't think that something is wrong with the discs since, as you said, they are not scratched and are in perfect condions. Maybe the drive is the problem though I'm not sure. The error doesn't sound like a damaged disk error to me.

You guys must have kickass eyeballs. I suspect that there was a write error when the discs were created.

aakerman, are you positive that the discs don't contain data errors? Try copying the data onto a different machine (not your friend's); what happens? Troubleshooting 101-- jiggle the cables, swap components, etc.

Try updating drive's firmware (for media compatibility) and your ASPI layer software - download from adaptec.com . Often solves strange optical drive problems.

Yeah, try in a diff'rent machine first -if they work on your friend's then you can almost rule out damaged discs and put it down to incompatability or a problem with your system. If they don't work on their's either then try warm soap and water and/or isopropyl alcohol. Then you might consider something like CD/DVD Diagnostic from infinadyne.

hmm strange:

disk1: error on my desktop, works fine on my laptop
disk2: error on my desktop, freezes my laptop when I try to load it

so there's definitely something wrong with the discs.. maybe the glue from the labels has messed with them.

hmm looked at that infinadyne diagnostic - I'm not sure that's what I need, it says: "finds lost files" - but they are not lost, just "broken" ? =)

Zepper -> I found some ASPI software on the adaptec site, but they are only for SCSI?

The ASPI layer software is ABSOLUTELY necessary for SCSI, but also serves some functions for ALL drive interfaces - it wouldn't be hard for me to point out a handful of threads on the ATF where updating the ASPI layer solved several pesky DVD problems (several of which were done at my urging). DO IT!
. In fact, extract the downloaded file and put the resulting files/folders on your "Tools & Drivers" CD or diskette and (with permission) install it on every PC you come in contact with - become one of the Johnny ASPIseeds, as it were. Seems that very few are aware of the need to do it. It will never hurt. The downloaded file (self-extracting archive) includes the ASPIchk utility which you can use to find out what version is currently installed.

ASPI layer software

Update the ASPI layer software first, reboot, and update your drive's firmware...

Back in the olden days Adaptec's Aspi was generally necessary, however Ahead provides its own with Nero etc., which may also be used with other burning software.

It could be the labels or just some queer incompatability betwixt those particular discs and drives.

I have used Infinadyne (formerly Arrowkey) CD Diagnostic with success for exactly those cyclic redundancy errors. But if the original files are still available then it may be best just to get other copies.
