Hard Disk Drive Diagnostics

Motor change is a highly complex process that requires sensitive handling. You can see loads of repair tutorials on the Internet regarding motor replacement that seems too easy, but it only seems like this.

In fact, this process requires a specialist’s approach performed in technical facilities.
The spindle motor is the most important component of a computer hard drive, responsible for the rotation of the drive platters on the axis and the uniformity and stability of rotation. The spindle ensures trouble-free operation of the hard drive for a long time.

As a result of power outages or an accidental drop of the drive, the drive is damaged, the hard drive will be useless, and the essential files will be inaccessible. Only a company specializing in HDD recovery can help in such cases.

HDD Spindle Motor Failure

In one of our previous posts, we discussed our case of a hard disk drive with a dead motor. Our client found out that the system does not boot because the hard drive has stopped spinning. It was likely that the problem was in the hard drive spindle. This is often the reason why the platters stop rotating, and the read/write heads lose access to data.

Listed Below are Potential Causes of Spindle Motor Problems:

Shock and Vibration

With strong mechanical stress on the hard disk, the spindle drive or axis is at risk of breaking or bending. Similar problems are also typical for external hard drives.

Power Outage

Power surges and power outages are fraught with damage to the electronic components of the spindle drive. As a result, the hard drive fails and needs to be repaired.

Hydrodynamic Bearing

Modern hard drives have begun to use hydrodynamic ball bearings instead of traditional. If a bearing fails, the spindle motor stops rotating, and the hard disk becomes unusable.

Motor Chip Failure

Spindle motor chip controls the spindle speed. With power surges, there is a possibility that the microcircuit will fail, which will entail the failure of the spindle motor.

Data Recovery from HDD with Damaged Spindle Motor

The client’s hard drive failed as the magnetic block of read/write heads did not receive any signal. It restricted the spindle motor from rotating. After getting approval from the customer, we started the recovery case. The spindle motor was started after complete internal diagnostics of the drive. 

First, we spun the spindle motor in a forced mode without analyzing the speed of rotation of magnetic disks, so the computer’s power supply should have a margin for peak power, and after our engineers removed the magnetic heads from the parking area, the speed of rotation was controlled by the signal of the servo-marker recorded in the manufacture of the storage device. 

By using electronics, we distinguished servos located between sectors from the total flow of readable data and, for them, stabilized the constant speed of rotation. 

Stability of rotation is essential when increasing the density of recording information on the magnetic surface of discs. It is crucial not to cause damage to the fragile device, so we work only in a controlled environment.

Hence, engineers of PITS Global Data Recovery Services perform the restoration process from physically damaged hard drives only in ISO Certified Class 10 Cleanroom. 

We have successfully replaced the hard drive motor using state-of-the-art repair tools in our recovery case. As mentioned before, the process was performed in specialized facilities, which helped us safely restore lost files.

The client was satisfied with the results and expressed his gratitude. When having a similar problem, contact us at (888) 611-0737 to request our professional help, and we will gladly provide you with it.
