Okay guys, trust me I looked at the rules before posting this but I need some major help ASAP.
I am quite experienced working with computers (Linux, Programming, web design, etc.)
However, I haven't learned anything about finding old data that someone deleted from their computer or overrided.

My mother is a court reporter, she's spent this entire weekend working on an 800 page transcript.
She somehow erased the entire document and then saved a blank document under the same name of the old document, therefore wiping out many hours of work.
She is currently having a heart attack. I'm trying to figure out if there is a way to go back and fetch the data.
I've told her not to save anything else until I see what I can do.

Can anyone please point me to how I might find the info and bring it back up? Please? She was dreading this particular job all week and I'd really like to help her get it back.
Links, explainations, anything would be great help.

X-Posted, sorry if its not allowed, this is a bit too important to care much.
