Part 1What Sshould I do First after Formatting a hard drive?

Formatted your hard drive by mistake, and didn't back up the crucial data stored on it? The good news is that you still have the chance to unformat a hard drive. Remember, the faster you unformat a hard drive, the more chance you'll have to recover your data. Also, after formatting the hard drive, you should keep the following things in your mind:

>> Don't partition the hard drive
>> Don't write any data into it
>> Don't install the Operating System or any program on it
>> Don't format it again
>> Don't try any untrusted unformat software to it

In other words, don't easily try to do any thing to the formatted hard drive, and that's very important. When the hard drive is formatted, you can't find any data on it. That's true, but only to your eyes. Actually the data are not really immediately erased out of the drive. They still stays somewhere, in an invisible status and this is because of the space taken by the formatted data is marked as available to reuse. When you write new data in, it will occupy the space for reuse. Then the formatted data is really and permanently cleared, and you can't get it back in any way. Thus, well protecting the formatted hard drive is extremely important, which can determine if you can unformat hard drive or not.
