Main motto: keep calm
If you ask a professional data saver like Lars M Mller of Recoverylab, then the affected people should first stay calm and not make wrong decisions. Especially in the case of strange noises, it is reasonable to think that this is a mechanical defect on the hard disk. However, the cause of this damage is not immediately obvious to laymen. For example, overvoltage, electrostatic discharge, material wear? Or the vibration of the internal or external data carrier may be caused by strange sounds.
To avoid worrying about losing data, do not panic and frantically try to access the hard drive again. Instead, turn off the device and disconnect the power. M Bangle explained: ※ The new read and write access do more harm than good. Therefore, it is also not recommended to use the conventional recovery tools on the Internet.
Don't worry about data loss
In most cases, if you follow the prompts, you do n’t have to worry about files. ※ The data rescuer said that we can almost always save the apparently lost data§, and he also maintains the delivery point of the data carrier in Stuttgart. M Bangle and his team use special software, some of which is individually programmed to skip sensitive hard disk areas, thereby protecting components. Free tools on the Internet cannot do this.
If necessary, replace the defective component and repair the defective hard drive. ※ After data recovery, we do not recommend that you further use the data carrier. M Bangller said another data loss is almost pre-programmed.
Do you fix the hard drive yourself?
People who want to restore photo memory, save their favorite music in MP3 form, or even save important files by themselves, usually only make things worse. "In the past few years, we have seen everything possible here," M Bang Lele explained. ※ Sometimes people use a traditional screwdriver to open the hard drive and damage sensitive components.
However, in a professional data recovery laboratory, the conditions are different from the home. On the one hand, data rescuers use special tools, on the other hand, only open the data carrier in the so-called clean room. It can be ensured that even the smallest dust particles will not cause further damage to the HDD read / write head and the disk.
Information: Hard drives are not the same hard drive
HDDs with moving parts usually produce cracks, clicks, or other strange sounds. The acronym HDD stands for Hard Disk Drive. SSD hard drives (SSD = solid state drives) have no moving parts, but are composed of several flash memories. These are digital memory chips and are also used for USB memory sticks. Clicks and rattles are unusual here.
If data loss occurs on the solid state drive, it should be attributed to logic errors, such as the drive being disconnected prematurely, the computer infected with a virus or accident, and sometimes deliberate data deletion.
Prevent data loss
In order to minimize damage in the worst case, data recovery experts recommend regularly backing up important files to a second external hard drive. On the other hand, it makes no sense to make a backup on a hard disk partition. "For portable devices, such as laptops or external SSDs / HDDs, temperature fluctuations must also be avoided," Lars M Bangller explained. In addition, you should occasionally turn off the computer to make the hard drive slightly quieter. Mueller: ※ Internal or external HDD / SSD for private use is not a permanent user.
