Ghost works on slightly damaged volumes

I recently rescued a dying drive that refused to accept writes. It had some corruption, but chkdsk couldn't do anything about that thanks to the inability to write. Therefore, I had to move the data to another drive before fixing the file system. I fired up Ghost, receiving some warnings about there being problems with the file system. Nevertheless, it successfully created a disk image on an external drive; I then wrote that image to a new disk. I was afraid that Ghost would try to interpret the damaged data structures in a way that made things worse, but it seems to have handled it well.
