Reason: Multitudes. Depends on a number of things including exactly what you
mean by 'lost everything', but if in fact the entire HD was 'lost', then
things point to a serious hardware hit.
Recovery depends on what you've done and the exact failure. Case in point:
you ask specifically about the system registry. Be aware that the registry
is composed of multiple files. If the problem is related to HD surface
defect involving the target of a defrag move and the file structure table
was altered to point to the new location and the old data location was
overwritten as a result of subsequent defrag operations then you're pretty
up a creek.
However it all depends on exactly what you mean by "lost everything". Be
specific about what you're seeing without interpreting what you think it
means.
