Inside A Hard Drive

Taking a Hard Disk Apart

Next (Head Stack Assembly) >

The purpose of this exercise is to completely take a hard disk apart, show the different components inside the drive and explain the functions of each part of the hard disk.

For this purposes we have chosen a 320 GB Hard Disk Drive manufactured in December 2006. The photograph below shows the drive with its lid removed. Please note that this was done in one of our clean air cabinets and hard disks MUST NOT be opened outside of a clean air environment.

Note the reflectivity of the platters, compare that to this one below that has suffered a head crash. In order to function correctly, platters need to be completely flat and without any dents, scratches or dust contamination. When running they need to spin concentrically with minimum vibration.

The gouges and surface damage to this drive are so extensive that there is severe damage to the head suspension arm. The read/write head connection wires can also be seen at each side near the tip of the suspension arm.
