How to Perform TestDisk Data Recovery on Windows

Recovering lost partitions and files with TestDisk involves a systematic approach. The steps below guide you through the process, ensuring you minimize the risk of overwriting data while maximizing recovery success.

Step 1. Download and Install

Download TestDisk from its official website. Select the latest version compatible with your operating system for download. Since PhotoRec comes bundled with TestDisk, you will find it downloaded along automatically.

Right click on the downloaded file and choose "Extract All" to unpack it to a folder. Do not place the downloaded archive or extracted program on the hard drive or USB drive you intend to repair or recover.

Locate the testdisk_win.exe in the folder and right click on it, then choose "Run as an administrator".

Step 2. Create a Log File

Upon launching, TestDisk prompts you to create a log file which can help track actions and be useful for troubleshooting if recovery fails. Select "Create" to save a log of the recovery process.

Step 3. Select the Disk

TestDisk will list all available drives connected to your system. You can identify the correct drive by its size and serial. Choose the disk from which you want to recover data using the arrow keys on the keyboard. Highlight the target disk and "Proceed", then press "Enter" to continue the process.

Step 4. Choose Partition Table

TestDisk usually auto-detects the correct partition table (Intel/PC, EFI GPT, etc.). Confirm the selection or choose the appropriate type based on your system. For most Windows systems, the default Intel/PC option (for MBR) is correct; UEFI GPT is common for newer UEFI-based systems.

★Tips:

Choosing the wrong type here may result in "Partition: Read error" during the recovery process.

Step 5. Decide "Advanced" Option

You will see several options such as "Analyse", "Advanced", and "Geometry", etc. Select "Advanced". This mode allows you to interact with the file system directly without modifying the partition table, perfect for recovering deleted files from a healthy partition.

Notes:✎...

Analyse: Analyze current partition structure and scan for lost partitions, used to fix corrupted partition tables and retrieve missing partitions.

Advanced: Advanced file system tool, mainly used to undelete accidentally deleted files from intact partitions, rebuild damaged boot sectors, and modify partition types.

Geometry: Adjust physical structure parameters of the disk, generally applied to very old hard drives or when TestDisk auto-detected parameters are obviously incorrect.

Options: Modify general settings of TestDisk, enable or disable expert mode, adjust log file options and more.

MBR Code: Write Master Boot Record code to the first sector to repair corrupted MBR and restore normal disk boot capability.

Delete: Delete the entire partition table. This will completely erase all disk partition structures and result in loss of all partitions.

Quit: Return to disk selection.

Step 6. Select Partition and Undelete

TestDisk displays detected partitions on the disk. Highlight the partition where data is lost. Click "Undelete" to search for lost files.

Step 7. Choose Files to Recover

Navigate through the listed files and select the ones you want to restore. You can use ":" to select the current file, "a" to select or deselect all files, "C" to copy the selected files, and "c" to copy the current file.

Step 8. Pick a Destination Folder

Specify a destination folder on a different drive to save recovered files. Press C to confirm your correct destination folder. Never save recovered files to the same disk you are recovering from to avoid overwriting lost data.

How to Recover Lost Partitions with TestDisk

Besides recovering lost files, TestDisk also supports restoring missing partitions without any data loss by analyzing the disk and restoring the correct partition table. This method is particularly useful when entire partitions disappear due to formatting, accidental deletion, or corrupted partition tables.

The preceding steps are the same as those for TestDisk data recovery. Select "Analyze" option after choosing the partition table.

Click "Quick Search" to scan for lost partitions. If it's no found, you can click "Deeper Search".

Once the target partition is founded, select it and the "Write" option to save the partition table to the disk.
