Fengniu Tech focuses on data recovery services in Zhengzhou and provides professional on-site data recovery. We have an experienced team of data recovery engineers and advanced recovery equipment, respond quickly on site and solve all kinds of data loss.

Our Service Advantages

  • Fast on-site arrival: rapid on-site response in the Zhengzhou urban area, so you don't have to travel

  • Pay after recovery: you are only charged once recovery succeeds, so you have nothing to worry about
  • Safe and confidential: a confidentiality agreement is signed to protect your data

Deleted or damaged device: do these things first so the data isn't lost for good

After accidental deletion or formatting,
  • ✔ stop using the device immediately, and don't write any new files to it
  • ✔ Don't keep powering it on and off, and don't run disk cleanup tools
  • ✔ Don't scan it repeatedly with free software (this can overwrite the original data)
  • ✔ Send it for repair as soon as possible - the earlier, the higher the recovery success rate
After water damage or a heavy drop
  • ✔ After water damage, never power it on , and don't try to switch it on or charge it
  • ✔ Don't blast it with hot air from a hair dryer, which can speed up corrosion
  • ✔ After a heavy drop, don't keep switching it on to test it, to avoid further damage
  • ✔ Cut the power and send it for repair as soon as possible - the window for chip-level rescue is critical
When must you go to a professional? Strange noises from a hard drive (head damage), water corrosion, a shorted motherboard, a failed SSD controller or a collapsed RAID array - handling these yourself can easily cause permanent data loss. Cut the power immediately and contact us (15333715773) for a free on-site diagnostic assessment in the Zhengzhou urban area within 30 minutes.

Frequently Asked Questions (FAQ)

On recovery scope, success rates, turnaround and pricing

It covers chat data recovery, recovery of accidentally deleted files, data rescue after system crashes, data repair after virus infections, recovery from hardware damage, and recovery after partition loss or formatting.

The success rate depends on how badly the media is damaged and how quickly it reaches us. We inspect for free first and give you an honest assessment - you pay only when recovery succeeds.

We reach you anywhere in urban Zhengzhou within 30 minutes. The actual recovery time depends on the data volume and the extent of the damage; most jobs are finished in 1-3 business days.

You pay after recovery - only a successful recovery is charged, so there is nothing to worry about. The price depends on the device type and the extent of the damage.

Yes, but the key is to stop writing new data to that storage medium. After accidental deletion or formatting the original data does not disappear at once - it is only marked as overwritable. The sooner you stop using it and bring it to us, the better the odds. In urban Zhengzhou we can be on site in 30 minutes for a free assessment, and you pay only after a successful recovery.

Yes. For devices that will not power on after liquid or drop damage, as long as the storage chip (flash memory) is not completely burned out we can read the data at board level, either through chip-level jumper wiring or by removing the storage chip directly (chip-off). Never try to power on a liquid-damaged phone - contact us as soon as possible; the shorter the delay, the better the chance of saving the data.

A clicking sound usually means the read/write heads are already damaged. Powering the drive on again scratches the platters and destroys the data for good. Cut the power immediately, stop using it and hand it to a professional cleanroom for a head replacement. We have a Class 100 clean bench and PC-3000 equipment to recover as much of your data as possible.

We offer a 30-minute on-site response in urban Zhengzhou, with a free assessment. Simple deleted-file recovery is usually ready the same day, while complex jobs such as cleanroom head replacement or RAID reconstruction generally take 1-3 business days. Urgent cases can be prioritised.
