This head replacement tool (Head Comb) is made for safe and easy head replacement on Seagate 7200.9 and Maxtor DiamondMax 20 hard drives with 1 platter.
These hard drives have a similar casing as other 7200.9 hard drives with 2 or 3 platters, but the height on which the platter rests is different. This is why a new tool was needed to support these specific hard drives.
During the whole procedure of head replacement, heads and platters have absolutely no contact. Heads are lifted over the NON-data area and safely guided over the platters. In process of installing back the donor head, same procedure needs to be done. Heads are guided over the platters with no contact and safely deployed in non-data area.
*This tool comes as a single piece, not in pair.
