Do you have any scratched discs lying around? Copying files from them might become really ugly experience. Windows has no concept of damaged media. It just copies until it fails. Sometimes failure is quick and painless, sometimes it keeps disc in the drive spinning until it explodes.
Solution is using file copying utilities. Some of these call themselves “recovery” and wait for users to pay for program they may use once a month (or year). Some are true about their function like Unstoppable Copier.
What it does
Unstoppable Copier copies file(s) from destination directory to target directory. If files are damaged it gets more thorough and attempts to re-read or skip damaged parts.
Mostly it just works but you can tweak it as well. This allows to control how hard app tries to copy damaged files or make it simply skip them. Plus few extra things.
Unstoppable Copier works from command line so can be easily used in Windows batch files or more complex scripts like AutoIt ones. There is also option to create batch files in internal (plain text based) .UCB format and launch them from command line.
Check my post with script to copy files from multiply discs, it can be easily enhanced with Unstoppable Copier for some major disc dumping. :)
Freeware, portable, scriptable. Not something needed daily but still excellent to have around just in case.
