Recover Formatted Deleted Data from your hard disk , USB , memory card

Recently I  unknowingly formatted my internal hard disk of laptop , about 500 GB of data lost . I got panic and i searched the ways to recover my data and i found a way using a opensource software called TestDisk , and its working , here is the step by step method

Requirements : Live bootable ubuntu or Linux Mint , i used Linux mint

install the test disk by

$sudo apt-get install testdisk

on terminal


after installing testdisk

go for recovery

1.open terminal
2. $sudo testdisk

3.

Log creation

• Choose Create to instruct Testdisk to create a log file containing technical information and messages, unless you have a reason to append data to the logor you execute TestDisk from read only media and must create the log elsewhere.
• Choose None if you do not want messages and details of the process to be written into a log file (useful if for example Testdisk was started from a read-only location).
• Press Enter to proceed.

4. 

Disk selection

select the hard disk or device to recovered

• Use up/down arrow keys to select your hard drive with the lost partition/s.
• Press Enter to Proceed.

5. 

Partition table type selection

• Select the partition table type - usually the default value is the correct one as TestDisk auto-detects the partition table type.
• Press Enter to Proceed.

6.

Current partition table status

• Use the default menu "Analyse" to check your current partition structure and search for lost partitions.
• Confirm at Analyse with Enter to proceed.

he first partition is listed twice which points to a corrupted partition or an invalid partition table entry.
Invalid NTFS boot points to a faulty NTFS boot sector, so it's a corrupted filesystem.
Only one logical partition (label Partition 2) is available in the extended partition. One logical partition is missing.

• Confirm at Quick Search to proceed.

Quick Search for partitions
