If you have lost an encrypted image, such as after a power shortage or system hang, you are probably familiar with the "corrupt image" message that displays when you try and mount the disk image. Yet you might be able to recover it. I spent some time researching how these files are created and was able to recover mine.

I posted the results on my web site.

kirkmc adds: I haven't tested this. Make sure you make a copy of the corrupted disk image before trying out the above procedure. It's worth noting that DiskWarrior can repair some corrupted disk images; I'm not sure whether it works with encrypted disk images, but when I recently reviewed the program for Macworld, I tested it on normal corrupted disk images, and it repaired all the problems I was able to create. Your mileage may, of course, vary, depending on the type of corruption.
