This head change tool (Head Comb) is made for safe and easy head replacement on Western Digital hard drive models BB, BD, JB, JD and all other models with 1 platter from Marvell families:
MAMMOTH
SABRE
UNICORN
This tool will also work on some of the pre-Marvell hard drives.
During the whole procedure of head replacement, heads and platter do not have contact. Heads are lifted over NON-data area and safely guided over the platter. In process of installing back the donor head, same procedure needs to be done. Heads are guided over platter with no contact and safely deployed in non-data area.
This tool doesn’t solve the head compatibility problem. It will only assure that the head replacement goes easily on supported drives.
*This tool comes as a single piece, not in pair.
