We all know that all our files in computers are saved in hard drives. And a typical hard drive is partitioned into at least two different sections. So you can run two operating systems (such as Windows XP and Windows 7) in your hard drive, although most hard drives are divided to create different file systems within the drive itself. Generally, hard drive partitions will be formatted using either the FAT or NTFS file system.
However, when partitioning a hard drive or restoring system, one of partition is formatted by mistakes, which means all your files will be wiped out! Well, if you haven't forgotten to make backup for all your data, you are luck! But wait, I have no backup! What can I do? Is it possible to recover data from formatted partition? Don't worry! The answer is— Yes! You can recover data from formatted partition by yourself! Here's how to retrieve the lost data.
What'll happen to my partition after I format it?
Formatting your partition does not make your data on it really erased. It only deletes the information about your files on the address table. And all your data are still there. They're just invisible or inaccessible. This means that the files are considered to have been erased permanently on the partition can still be recovered. However, just take note that once you save new files in the formatted partition, theses files will be written over the files you want to recover. Don't pannic! It's highly possible for partition recovery!
