As an AutoCAD user for some period of time now, I have encountered so many problems involving data losses, data corruption and damaged drawing files. Which trigger when the AutoCAD that I am using encountered a program error, system error or a windows manager failure. And to some point an, unnoticed power failure.

Usually when I encountered this, the first thing that comes to my mind is the questions, what will happen with the data that I am working on? will it be loss? or can I recover it without any damaged at all?. Especially when times I forgotten to save it.
