This is indeed a forum for asking for help, but asking for the best data recovery program or similar is not part of it.
I came here and asked for help. You replied saying that I could possibly recover my data with "data recovery software". Since the term "data recovery software" is rather vague and a Google Search
yields more than 5 million pages, it seemed to me that the most natural thing to do was to ask you to clarify your previous statement.
Instead of tossing me out of the forum you could have simply told me if you were familiar with any such programs that were likely to work or could have given come hints or clues that would aid my search. You could have at least responded to my second question that asks if the recovery would have more chance of success running from the guest os or from the host os. if you didn't know all you had to was to say so.
I see no reason for you to with hold that information from me and the other members of this forum. Not only was your reply non-responsive and impolite, more importantly it may have dissuaded other people from offering their opinions and suggestions.
You lost data, that's too bad but not much we can do about it. The problem about the reverting snapshot is something you can discus here.
It's a moot point now, isn't it. What a darn great feature!
That is a strange matter. What checkbox was it?
1. Right click->close VM on Linux host task bar
2. Close Virtual machine Dialog pops up
o Radio Button - Save machine state
o Radio Button - Send shutdown signal
o Radio Button - Power off machine
 Revert Snapshot check box
3. Press OK
4. Confirm dialog does appear but language is vague, just repeats checkbox text
5. VM closes
6. Start VM - everything wiped clean
Thanks for all your efforts and for making me feel welcome on this forum. You have been a great help and I just can't say know how impressed I am with the "revert" function in particular and how pleased I am with virtualbox in general.
