Prompt formatting? Don't click!

Tips Need to format is the most common failure of USB flash drive/memory card, and it is also the place where data is most easily destroyed by hand slip. The correct approach is:

Unplug it immediately, don't format it.. Click on the format, the difficulty and cost of data recovery will increase.
Do not repair with chkdsk. The system pops up scanning and repairing the same may damage the data structure.
What's in the log card?It is easy to check the integrity when restoring.
Send to professional institutions for recovery. The file system damage caused by the disk is not recognized, we use professional tools to reorganize the file system, the success rate is very high.

A lot of people panic when they see the formatting prompt, and when they do, the data disappears instantly, but the data is still there, just the directory of the file system is destroyed. We can rebuild this directory.

USB flash drive/memory card recovery process

The recovery process for small storage devices is similar to that of hard drives but has its own characteristics:

Step 1: Evaluation: Describe the fault (prompt formatting/disc-recognition/error deletion), and judge whether the logic fault or the main control physical fault.
Step 2: Professional testing: logic fault direct read recovery; master damage need to read flash chip.
Step 3: Data Extraction: Reassemble file system or read chip data, export files.
Step 4: Verify Delivery: Check the integrity of the file (especially whether the photos and documents can be opened normally) and copy them to you.

For physically damaged USB flash drives (broken, main control burned), we can rescue data by flying lines or reading Flash chips, but the cost is relatively high, suitable for data is more important.

⚠️ USB flash drives and memory cards are consumables in themselves., especially miscellaneous cards and long-term use cards, may be bad at any time. Important data (graduation thesis, wedding photos, work documents) must not only exist in a USB flash drive or a card, at least in the computer or cloud have a backup. Recovery is remedy, backup is fundamental.

FAQ

About USB flash drive and memory card recovery, we are often asked

USB flash drive prompt format, click what to do? Can you restore it?

Click format also don't panic, immediately stop writing data. Quick format only rebuilt the file system, the data body is still there, there is still a chance to recover. But if you copy the file after formatting, the overwritten part will not be found.

Yes. As long as the Flash memory chip inside is not broken, we can extract the data by flying wire or directly reading the chip. The cost is relatively high, suitable for situations where the data is important.
