The benefits of the H.D.R.C Spindle 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 temperature of the
spindle motor will vary under the effect of the heat produced during the
operation of the motor itself, or the changing of the atmospheric
temperature, however, temperature variation of upper and lower ball bearing
is different. This will sometimes lead the temperature difference between
the upper and lower ball bearings.
In the spindle motor of the hard disk drive device, the lowered accuracy of rotation of the rotor
hub will lean the hard disk or magnetic storage medium, or drive the disk in
an eccentric manner to occur the disk crush to impair the reliability of the
hard disk drive device.
Accordingly, 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.
Some times Hard drives do not responses or crashed due to spindle motor and bearing problem. At that
situation data could not be recovered and recoverable by many data recovery
companies. 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.
