Every recovery begins with a diagnosis. There are two broad categories.
Logical data loss covers deletions, formatting mistakes, partition issues, corrupted file systems, and database errors. The hardware still works. Your chances often depend on whether the missing data has been overwritten by new activity. Quick action matters.
Physical data loss covers mechanical failure, damaged heads, fried controllers, worn flash cells, and water or fire exposure. Here, the device itself is the problem. Success depends on cleanroom techniques, specialized tools, and how the media is handled from this point forward.
Time, device condition, and your next steps link both categories. The longer a failing device is used, the more damage can spread. The more you write to a drive after deletion, the more likely you are to overwrite the very blocks you hope to recover. This is why experts recommend stopping all activity and moving to structured triage.
So, is data recovery possible if you shut everything down quickly and avoid writes?
