Spindle bearing And Motor replacement Tool
Spindle motors are the devices that spin the platters. They can spin these disks at a set rate, ranging anywhere from 5400 RPM to 7200 RPM! Some spindle motors are located in a position below the head disk assembly, while others are built into the hub of the platters. The modern ones are usually all built into the hub because this takes up less space and thus allows for more platters to be built in. More platters equal more storage space.
The object of the present invention is to provide a spindle motor of high accuracy of rotation irrespective of the temperature differential for driving the hard disk or disks of the hard disk drive device.
Hard drives that have failed due to spindle motor and bearing problems are not recoverable by many data recovery companies. The issue is not that the data on the hard drive is damaged; rather the problem is the lack of specialist equipment to correctly remove a seized / damaged motor assembly whilst maintaining the integrity of data on the platter surface. Actually Data are remains same as in the platter surface but not in the readable mode. Some Data recovery specialist give up saying damaged Hard-disk. But in this situation data still can be recovered by Exchanging the spindle bearing and motor. HDRC have developed a hardware device that safely removes the motor assembly from hard disks, allowing the platters to then be transplanted to a donor drive.
