I was not looking for miracles. :-) Let's say I was working on a very
large data file, and had added to it over a 3-5 day period. When the
disk is 'fixed' is this file completely gone, or like it was before I
started working on it, or has part but not all of the new info, or
since it has been 4-5 hours since data was added, even might have the
latest data? What is that file most likely to look like?
