I feel awful for a client that finds themselves in this situation.

engine difficulty on a hard drive

Once an external hard disk has been dropped, regardless of what the elevation, inner components will probably get the brunt of it. The first component to get the brunt of it’s the engine. This is really where I cringe. Of all of the things that can fail, we always hope that it is not the motor.engine difficulty on a hard drive I really don’t think anybody in data recovery business likes to hear about engine difficulty on a hard drive with multiple disks. Hey, if it is a single platter hard disk, we’d provide a bit of relief. We welcome a laptop hard disk with multiple platter disks with motor issue. Request why. The easy response is alignment.


Okay. Allow me to clarify what happen to the engine , and the alignment issue. The engine is the component that the platters sit on nicely and turns them at a given rpm. Inside the motor, we locate motor bearings. These bearings help the motor turn easily without a vibration. Storage Review has a great reference manual related to the ins and outs of disk drives. You need to read it if you want to understand more.


But once the best external hard drive is lost, and the motor does not spin, the bearings most likely are dislodged from their grooves and then clog the distance the motor should spin. Oftentimes, the motor becomes rigid that no torque pressure applied will do some good. Sometimes, the engine is less rigid, but won’t turn freely. In either scenario, it doesn’t look good.


About alignment: When the engine cease or become rigid after the fall, especially when the hard disk was operating, the disc platters may change. The sudden stop of this platters may shift them slightly off the engine. Hard drives with numerous platter disks are aligned at some time before dispatch.
