How to recover data from a damaged HDD safely
Recovery from HDD starts with recognizing the symptoms, not with installing another program. Here we separate logical, electronic and mechanical failures into specific scenarios.

Computer does not see the external drive
A glowing LED and silence in the system is a common scenario with USB drives. We show you how to distinguish the problem of the housing, cable, power supply and the storage device itself.

Do not format a drive before data recovery
Quick format, full format and SSD TRIM can all change recovery options. Pause before confirming a format prompt.

Do not install recovery software on the source drive
A recovery program saved on the same drive may overwrite the exact files you are looking for. We explain why this error is so common.

Do not open a hard drive at home
An open HDD outside the cleanroom quickly collects dust and loses the chance for safe recovery. We'll show you why "I'll just see for a moment" is a very bad idea.
