How to recover lost data from HDD?

HDD hard drive is where user data is stored to work on the computer. Although hard drives usually have a very long life, sometimes they also have unexpected problems that cause user data to disappear. Even during use, sometimes when cleaning up data, we accidentally delete - format the hard drive, losing all important data. Most users who fall into this situation are often very confused. So is there any way to recover HDD data?

How to recover lost data from HDD?

In case the hard drive fails due to technical error or product error

Due to damaged circuit board

According to the structure of the hard drive, the HDD will include a circuit board and a read-write part with a magnetic disk containing data inside. Based on your judgment, or when you plug in the power, you see that your hard drive does not work, it is very likely that the hard drive control board is damaged.

Due to internal mechanical failure

When using the hard drive, you hear clicking sounds inside, it is very likely that your hard drive has encountered a mechanical error. This case is very difficult for you to handle at home. During the production process, your hard drive is assembled in an absolutely clean vacuum environment without a single particle of dust because even a small particle of dust inside will cause your hard drive to not function normally. Therefore, to be able to replace the mechanical part of the hard drive, you must remove the hard drive in a specialized room for replacement.

Of course, no matter how hard you try to clean your room, you can't turn it into a dedicated room at home. Instead, find a data recovery center to help you with this task.

Due to formatting the wrong hard drive

Formatting the wrong hard drive is not a rare error for users, especially for those who use large capacity hard drives and have the habit of dividing multiple hard drives. Although dividing multiple hard drives will be more convenient during use, making it easier to arrange data, but if you do not remember the exact data area when clearing the memory, you will encounter a lot of trouble. Many customers when discovering that they have formatted the wrong hard drive were shocked to find a way to recover the hard drive. 

In this case, it is also very difficult for you to recover data at home. Of course, there are some specialized software that are said to be able to recover data, but they can only save 60-80% and of course you also have to pay to use this software. Instead, you should find reputable data recovery centers to recover important data.

The absolute thing to remember is that after formatting the hard drive, you must avoid overwriting data on this hard drive. This will make things worse. And if you write too much data over that partition, even the most sacred centers will be helpless.
