The following user guide will give step-by-step instructions on how to change read/write heads with HddSurgery head replacement tools on Western Digital hard drives.

More details can be found on our website http://www.hddsurgery.com

Western Digital hard drives from families Sabre, Hawk, Starling, Raider and Zeus belong in the category of disks that "park heads" above the magnetic platters. That way of functioning implies that, in a situation when the drive is powered off, the heads are located on the surface that has no sensitive magnetic material. This allows drive to start the motor to the required speed.

The purpose of HddSurgeryTM head change tools is to enable safe heads passage over the "data" area above platters surface, and to provide non-contact transfer to patient disc.

HDDS WDC BB/JB/JD/JS p2-3 (2 or 3 platters)

This head change tool is made for safe and easy head replacement on Western Digital hard drive models BB, JB, JD, JS and all other models with 2 or 3 platters from families: Sabre, Hawk, Starling and Raider.

HDDS WDC KD/KS/YS p4 (4 platters)

This head change tool is made for safe and easy head replacement on Western Digital hard drive models KD, KS, YS and all other models with 4 platters from Zeus family. As there is no conceptual difference between these two tools, we will explain only the functioning of HDDS WDC KD/KS/YS p4 tool. In the case of HDDS WDC BB/JB/JD/JS p2-3, apply the same procedure.

1. Step - Mounting the tool on actuator arm

Remove screws holding flat cable contact and with a finger push contact from the bottom upwards to release it. The pressure from below may cause flat cable contacts to pop out and possibly damage platters, so hold firmly top of a flat cable contact with another hand while pushing related plastic. Before applying pressure remove screws from their holes.
Carefully center the tool over the center hole of the hard disc head. Take care that the notch on the bottom of the tool coincides with the commas in the actuator arm base. Tighten the screw to perform tool installation.

With your right hand make sure that the tool shank with snouts remains in the area outside of the platters. Be sure to tighten the screw in order to ensure good contact and proper tool height.

2. Step - Lifting the heads

By horizontally moving tool shank we slide the tool over platters. Construction of tools enables heads to lift on tool snouts by relatively small force. If you feel that the necessary force is greater than the expected, check tool positions and possible damage to the HDA assembly. Push the tool as far as limiter is allowing.

3. Step - Securing the tool

The tool has a hole at its edge, which coincides with the hole in the head arm. Some Western Digital hard drives have this hole in their head, and some don’t. For drives that have this hole, place the securing pin as an additional measure of security. The leftmost position is necessary to ensure the bound between tool and actuator arm. If the connection of the tool and actuator arms is not properly engaged, heads slipping is possible during disassembling.

4. Step - Moving the tool outside of platters area

By vertical scrolling move the tool (previously secured by pin) to the initial position. If the head arm doesn’t have a hole in which you could place the pin, push the back side of the head arm (magnetic coil) together with the tool itself to prevent heads from slipping.

5. Step – Unscrewing the head assembly

Remove the screw that’s holding the head and tool attached to the drive itself. Now the head assembly can be lifted. When this screw is removed, heads and tool are not having a tight connection anymore. Do not try to dismount the heads by pulling the tool.

Image

6. Step - Dismounting the heads

To lift the head assembly, tweezers are needed. Use tweezers to grab the head assembly through one of the holes on the head arm. Pull the head arm up using the tweezers. To make sure that the head assembly goes straight up, use one finger to pull the back side simultaneously (side where the coil is). Don’t try to dismount the heads by pulling the tool.

Image

7. Step - Mounting the heads in a new drive

Place the tool with head assembly to its place in new hard disk using the tweezers. Screw the screw to tighten the tool with head arm to the disk.

Image

8. Step – Moving the heads to the parking zone

Push the tool to scroll the heads back to their place above the platters.

Image

9. Step - Removing the pin

If your drive had the hole for the securing pin, carefully remove it when heads are above the parking zone.

Image

10. Step - Moving the tool outside of platters

Horizontally push tool shank with a finger to return the tool outside of platters. With your other hand, hold back side of the head arm (magnetic coil) to prevent heads from moving.

Image

11. Step - Dismounting the tool

Take out the screw and remove the tool.

Image

Put the lid back and close the disc. Put PCB back and clone the drive.

The purpose of our tool is just to transplant the heads from one hard drive to another the safest way possible.
