Ignore CRC Errors to Copy Damaged Files

As I type this, I am watching a new addition to my utilities toolkit copy damaged files from a hard drive with several bad sectors that is about to be replaced.

Trying to use most programs, like a basic drag and drop in Windows Explorer, or Robocopy, or XCOPY (remember that!) will fail when the filesystem kicks up a CRC error on the file.  I’ve also had this happen with scratched CD’s and DVD’s.

The new in my software toolbox is Unstoppable Copier, a freeware tool available here. I’ve tested it once, and it seems to work as advertised. It did more than Windows Explorer managed to do, at least.

There are also roundabout ways to do this with disk image software that can ignore errors – such as ddrescue – which I’ll be running on this same hard disk soon.

    robocopy c:\ d:\ /MIR /R:0 /W:0

    /MIR = Mirror entire directory structure (can use /E instead)
    /R:0 = 0 retries for read/write failures
    /W:0 = 0 seconds between retries

    Thanks for the Unstoppable Copy tool. I have a 15 GB Outlook PST file I use for archival. The disk it was on went bad and I couldn’t find anything that would copy it over. Using your tool and the Outlook repair tool I was able to recover some of that data
