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? -Al andrew zajac-2 wrote: > > It started off this session with 629 different areas with errors which > totaled 1500 kb of missing data.
