Overwriting is a process of writing a binary set of data in computer data storage and is a term used to describe when new information replaces old information or data. In general it writes over the previous data, hence the name. Overwriting generally occurs when unused file system clusters are written upon with new data, though overwriting is also used in security algorithms. These algorithms use a precise set of rules to remove any part of an original data from the memory by writing a new raw data on the memory.

Data that has been overwritten, even just once, is generally considered to be unrecoverable. There have been theories regarding the feasibility of recovering overwritten data, but none have been put into actual practice. As such there is no evidence in favor of recovering overwritten data, but several suggesting it is entirely impossible.

Windows 7 (Microsoft Windows 7 Enterprise, Microsoft Windows 7 Home Premium (32/64 bits),Microsoft Windows 7 Professional 64-bit Edition, Microsoft Windows 7 SP1, Microsoft Windows 7 Starter, Microsoft Windows 7 Ultimate 64-bit Edition, Windows 7 32 bit and Windows 7 64 bit) data recovery technology is not as complex as you though. Files, usually are divided into pieces, like 5KB a piece, which means, for example, if there is a 1MB file that in your hard drive, it will be about 200 pieces of data that store every possible place in hard disk. And there is a record for hard disk, which is named as partition table, the record writes down the locations of all sectors. This helps Windows 7 to identify the file and run it when you want to. When you delete or formatted the files, Windows 7 just rebuild the partition table, leaving data pieces there, and consider these pieces are empty, which can be overwritten after a while. So what a Windows 7 file recovery tool do is to find these pieces and make them together. Then it helps you to find the deleted or formatted files.
