Effective Optical Disc Repair?
CyberKnet writes "I have an extensive music collection on original CD media. While most of it is in impeccable condition, I have a few discs that have suffered extensive scratching through listening to the disc either via a portable disc player, or in a car CD stacker. I've long since learned the error of my old ways and don't listen to discs in those devices any more, but those discs are irreplaceable in many cases. I would very much like to be able to repair them or have them repaired to original condition, or at least well enough that I can pull the tracks off once and archive the track data. I have heard really uncomplimentary things about devices like the Skip Doctor; ranging from it not helping to it making things worse. I've heard great things about JFJ devices that are seen on the counters of most Hollywood and BlockBuster video stores, but even their consumer devices start at $250. I would appreciate any other suggestions for devices that people have had personal experience with that won't break the bank."
FUD
Wiping outward vs wiping in circles makes no difference!!
The idea behind this is that you don't want to damage any other data near (along the spiral) the unreadable part.
The idea is that data, and the CRC data, is stored sequentially along the spiral, and that wiping in a circular motion will damage more data in a given sector.
However, when you're wiping with your fucking finger or even some sort of small foam/cloth tool, you're rubbing the shit out of the damaged area, and everything around it.
If you wipe outward (radially) over a fucking scratch, you're still wiping over the damaged data and all of it's CRC data and all of it's neighboring sectors.
This was true with CDs, even truer with DVDs, and even truer with BluRay/HD DVD.
The basic premise behind this bullshit is that wiping your disc will damage it.
Wipe in whatever fucking direction helps remove smudges and smooth out divots and scratches. Remember to view your work STRAIGHT on like the laser does.
either not trusting the emulation or just doesn't work
Sorry to burst your bubble, but WINE Is Not an Emulator
