Disintegration of the Spindle Motor
One of the physical problems encountered in hard drives is the disintegration of the drive motor. The failure is usually caused by the hard drive’s fluid dynamic bearing seizing. In that kind of cases, it is possible to detect the following symptoms: The hard disk starts to fade and immediately stops. Other types of hard disks often record recurrent signals. Recently, one of the hard drives with similar problems listed above was presented to our laboratory for technical inspection. The client assumed that the disk had been physically impacted before. Standard diagnostics revealed that the read/write heads went stuck on the magnetic surface, and most importantly, the spindle motor went dead as well. Successful recovery required several donor drives. So, more than 86% of the data was recovered, which is quite challenging for such damaged drives. Thus, having noticed similar symptoms, we do not recommend to start a drive-rather delegate the issue to professionals.
