To use a disk analyzer for data or partition recovery, you must first clarify whether you are using a Disk Space Analyzer (to recover storage space by finding large files) or a Low-Level Disk/Partition Analyzer (to recover lost, deleted, or corrupted data).
While space analyzers help you clean up clutter, low-level tools scan deep into the drive’s structure to rebuild missing parts and rescue files.
Method 1: Using a Low-Level Analyzer for Lost Data/Partitions
If your files vanished due to a format, corruption, or missing partition, you need an advanced raw filesystem analyzer like TestDisk or DiskGenius. Step 1: Protect the Source Drive Stop using the drive: Do not write new data to it.
Isolate system drives: If recovering from your main OS partition, detach it or boot from a live USB. Ongoing background processes can permanently overwrite your lost files.
Create a sector image: Whenever possible, use tools like Disk Drill to create a byte-to-byte backup image and scan that instead. Step 2: Select and Scan the Hardware Data Recovery on a Formatted Drive with TestDisk by Britec
