Windows Tips: 10 steps to recover formatted or deleted data

I was very frustrated because the data in my personal pen-drive was deleted unconsciously by myself when I was trying to install new OS in my computer. It seemed quite impossible for me to recover them after the formating process. However, the data inside my pen-drive was very important to me. Luckily, I found a free and quite user-friendly program, testdisk.The procedure to recover the data in my formatted pen-drive is stated as below:

1. Download the free testdisk and extract it to your computer.

2. Launch the testdisk_win.exe program in the win folder.

3. Choose the size of disk which you had formatted.

4. Select "Analyse" to analyse it.

5. It may show nothing in your disk initially. Select "Quick Search" to retrieve your formatted or deleted data.

6. Select "N" (No) if you are sure that you did not use vista to format or delete your disk.

7. Change the "symbol" at the left hand side of the sentence to "P" (Primary) if you not sure if it is a boot-able disk. Note, all your data may permanent lose if you select "D", (Deleted).

8. Select "Write" to start recovering your data.

9. Confirm this process to start the recovery process.

10. Press enter and reboot or restart your computer now.
