How to recover files from hardware failure?

Hardware failures are the most common causes for data loss. How can we deal with these computerhardware problems? What are the common hardware failures?

1.    Hard drive circuit boards damage

Generally speaking ,this damage can be caused by the external power supply line problems, the power failure  of hard disk, or a computer poor quality circuit board, which lead to burning out the circuit board and breakdown  of the chips. The data loss in that case is relatively easy to deal with. But the burn out of BIOS chip on some circuit board may cause difficulty in repair, even cannot be repaired. Most of this case always shows that the medium has no any reaction after electrify. And the motor does not rotate, or has obvious burn marks.

2. Hard drive firmware damage

Hard disk firmware damage are the failures of its factory information, including location information, the defect table, hard disk parameters, the drive module. When the hard drive is in using, it may cause some firmware loss or damage which lead to read and write error or unable recognition. In that case, you do not need to open the hard disk for data recovery. You just need to use the same model of hard disk to read the hardware and then write on the damaged hard disk.

3. Hard disk bad track

The long time using of hard disk, improper shutdown or sudden power loss may lead to the hard disk getting hit, then there will be bad tracks and the data cannot be read. In that case, we need to make a hardware mirroring to get the sectors of damaged hard disk are mirrored to another good hard drive, and then to recover data on this drive. The bad track always present with slow read and write speed, frequent crash and blue screen.

4. Hard disk encryption

Many users may use encryption to protect and maintain their hard disk. However, once you have lost the password, you may have no way to read data. The head damage, offset, no addressing, abnormal noise of hard disk may need to open disk.

These are the common hardware failures. You need to pay attention that if the medium has a problem, you should cut off the power first when have no idea how to deal with. Then you can contact with Hdata recovery engineers for data recovery.
