Re: [Bug-ddrescue] ddrescue - disk 2 disk (ntfs)

Thanks Andrew, 

That makes perfect sense. I have found after mounting the images (which is
of a NTFS windows drive) that most of the sub directories under C:\Windows
are missing. This is of course far more than 1500Kb of data.

The only way that I can reconcile this is to think that the place that holds
the index of files/directories (FAT table?) is part of whats missing, so
although the error size is small its killed the directories in a indirect
way???

Make any sense?
