How to recover draft deleted data

I was trying to copy the draft messages onto a .doc Suddenly the system started re-booting itself; it has been going on for sometime now. When the system got re-booted, the document was showing a line. Earlier, when the system shut-down due to power failure or for whatever reason, when we opened any doc, there used to be list of files on the left side of the opened file and prompt if we want to write that lost file. NOW nothing of that sort. NOW, I DONT HAVE THE MATTER COPIED ONTO THE DOC EXCEPTING THE DOC WITH THE SAVED NAME AND DELETED ALL DRAFTS. I NED TO EITHER RETRIEVE THE MATERIAL VANISHED FROM THE DOC OR THE DRAFTS DELETED OR PREFERABLY BOTH.

Now there is no option undo the discard draft mail delete popup
