I Formatted or Deleted by Mistake: Your Real Chances of Recovery (and the Error That Destroys Everything)
Deleting a file or formatting a drive does not physically erase it: on a hard drive, the data stays on the platters as long as no new data has been written over it. Your chances of recovery after an accidental deletion or format are therefore often good, on one imperative condition: stop using the device immediately. This guide explains why deleting is not erasing, how the allocation table (the drive's table of contents) works, and where the real danger lies: overwriting, caused by updates, antivirus or defragmentation that write into the freed space. You will understand the decisive difference between a hard drive and an SSD (where TRIM erases fast), between a quick and a full format, and above all why the recovery software you download can destroy what it claims to save. Finally, how a lab protects your device with a bit-for-bit copy before any intervention.
