Motor problem on WD Sadle G6 drive
Western digital drives are known for their motor durability and lack of problems with the jamming. However, there can be other problems that can happen with the bearing and no hard drive is immune.
The video below shows two identical Western digital hard drives, but there is a significal difference between them - platter rotation speed.
What could cause this kind of problem? Our analysis shows that the motor was non functional in a way that caused the loss of the ability to spin at the appropriate speed.
We think that the source of this mulfunction can be caused by unevenly distributed fluid inside the bearing. The consequence is increased friction and reduced rotation speed of the hard drive platters.
What do you think?
