Data recovery from bad hard drive

It’s quite nature that the hard disk has some problems after a long use. But frequent hard disk failure is unusual for hard disk normally has a service life. Why you always have data loss from hard disk failure? It may due to some improper operations.

Cut the power off by force may cause physical damage of hard disk. Current power supply and ATX  motherboard  design has achieved the function of a soft shut down. However, you still need to close the running programs as many operations may cause crashes after cutting off power for compatibility. That may for the unfinished reset.

When crashes happen in soft shut down, the correct way is to press RESET key to enter window again and then finish the operation of shut down.

What are the hard disk failures?

1.    CMOS cannot recognize the disk

2.    The crash sound of head occurs

3.    The motor does not work

4.    The head dislocation causes dislocation in data reading

5.    Difficulties in starting, read and write; frequent crashes; format error.

6.    Apparent burn marks on circuit board

The categories of physical failures:

1.    Disk body Faults: head burnout, head aging, chip damage of head, motor damage, head offset, zero track bad,  bad sectors, the disk scratch.

2.    Circuit board failure: circuit board damage, chips burnout, broken needles and lines.

3.    Loss or damage of firmware information.

The  troubleshooting methods for hard disk physical damage.

Opening hard disk must be carried out in a super clean environment, and then use special equipment to positioning the head. For the hard disk has a body failure, you can use the hard disk of the same type as replacement parts.

Adopt the method of hardware mirroring, and recover data on a good hard disk.

To recover data by yourself is risky when there is a physical damage Therefore, you’d better ask the professional data recovery center for help. Hdata recovery engineers provide professional hard drive data recovery services for you.
