How do I restore the hard disk data?

Filed under: computer knowledge — admin @ 6:26 pm

Q: my Hitachi 40GB laptop hard drive suddenly can not be identified, I installed it to the USB mobile hard disk box can not be used. Now the hard disk does not matter, mainly the data inside is very important, what are the ways to restore the hard disk data?

Answer: this situation is more complicated. First of all, it is necessary to judge whether the circuit board of the hard disk is damaged: if the hard disk does not rotate when it is powered on, then it is likely to be a fault in the circuit board. As for the hard disk which is damaged by the circuit board, the data of the hard disk can be saved completely after replacing the circuit board. If it is not a circuit board fault, then it is likely to be a hard disk internal problems, such as head and motor failure. For individual users, such failures are almost impossible to deal with and can only be assisted by professional data recovery providers.
