1. Why can data be recovered after formatting?
When the USB flash drive is formatted, the system only clears the file allocation table (FAT), and the actual data still exists in the storage medium until overwritten by new data. The following is a comparison table of data recovery principles:
| Operation type | Data status | recovery probability |
|---|---|---|
| Quick format | Clear directory structure only | up to 90% |
| fully formatted | Part of the data is overwritten | About 30-70% |
| low level formatting | Completely wipe data | Close to 0% |
2. Ranking of popular recovery methods (based on the popularity of discussions on the entire network)
| Ranking | method | Applicable scenarios | Operation difficulty |
|---|---|---|---|
| 1 | Professional software recovery | Misformatting/virus attack | ★☆☆☆☆ |
| 2 | CMD command fix | Formatting caused by system error | ★★★☆☆ |
| 3 | Registry modification | U disk showing abnormal capacity | ★★★★☆ |
| 4 | data recovery service | Physically damaged storage device | Professional organization operation |
3. Step-by-step recovery guide
