Every storage media has a shelf-life. In most cases it is just a few years. Loosing precious data due to damaged media can be a devastating experience. But even if Windows File Copy fails, all hope is not lost. You can still salvage your data using tools like RoadKil’s Unstoppable Copier.
RoadKil’s Unstoppable Copier works on all media including Hard Disks and Optical Disks. Unlike Windows, Unstoppable Copier doesn’t give up when it encounters an unreadable bit. It will attempt to read the damaged portion multiple times. In case your media is badly damaged and the data can’t be read, it moves on to the next bit. Unstoppable Copier reads as much of your data as possible and then pieces them together. This technique works especially well with multimedia content. Even if some of the data is damaged beyond recovery, you would still be able to play the video or audio(with a few frame skips).
Unstoppable Copier also provides a few other advanced options like Batch Processing mode and File Copy automation which advanced users will appreciate. You can use it as a daily backup software by creating a batch transfer and running it as a commandline script.
RoadKil’s Unstoppable Copier obviously has its limitations. It can’t recover something which no longer exists. However it works quite well on partially damaged disks (especially for multimedia files). Unstoppable Copier works on hard disks with bad sectors as well as scratched optical disks (CD/DVD) and is available for both Windows and Linux.
