One of the physical problems experienced in hard drives is the disintegration of the drive motor. The failure is usually caused by the hard drive’s fluid dynamic bearing seizing.
It is possible to detect the following symptoms in situations like this: the hard disk starts to fade and immediately stops. Other types of hard disks often record recurrent signals.
The hard drive with the listed above problems was recently presented in our laboratory for technical inspection. Standard diagnostics revealed that the read/write heads went stuck on the magnetic surface, and, most importantly, the spindle motor went dead as well. The client assumed that the disk had been physically impacted before.
Successful recovery required several donor drives. More than 86% of the data was recovered, which is impressive for such a damaged device.
Thus, our team does not recommend running a drive when noticing similar symptoms. In such a situation, delegate the issue to professionals.
