Mechanical problems can be related to physical and/or electrical component failures. If there is nothing logically wrong with the drive, then it is definitely a mechanical issue. A clicking hard drive is usually a sign of a major mechanical problem, except in cases like the one mentioned above where System Area corruption can also be a cause. That is the common term used to describe a hard disk that is clicking. This doesn’t mean there is a physical problem with the drive, such as the heads, it just manifests itself in a similar manner.ĬLICK HERE TO GET YOUR DATA RECOVERED FROM A FAILED HARD DRIVE. And even if you have the original PCB, the drive can click if any of the other critical modules become corrupted within the System Area. That’s why just swapping out PCB’s doesn’t work on most hard drives, because the data stored in the modules doesn’t match. The data that is stored on the chip has to match up with what is stored on the platter. For example, in many hard drives defect lists (known as G-Lists and P-Lists) are stored on the platters and on a chip mounted to the PCB. Corrupted firmware modules can cause a drive to click, because as the heads sweep across the platter looking for the data they need to calibrate, it’s either not recognized or doesn’t match up with what is stored in other areas of the drive. Sometimes it can be a much easier, but still complicated fix. Just because your hard drive is clicking doesn’t always mean it has a major mechanical problem with it. A Clicking Hard Drive Is Not Always As Bad As It Sounds If the drive cannot detect the data it needs to in order to calibrate, it will usually spin down after a few tries. As the heads sweep back and forth across the platter surface they hit the limiter that keeps them from going too far in either direction. The clicking sound is mostly the base of the actuator arm hitting a limiter.
A hard drive that clicks or makes any unusual noises can do so for a variety of reasons.
When they hear the familiar repetitive clicks coming from their computer or external hard drive. That is probably the first thought that might run through a person’s head.
