HddSurgery™ head change tools
Seagate hard drives belong in the category of disks that "park heads" above the
magnetic platters. This way of functioning implies that, in a situation when the drive is
powered off, its heads are located on the platter surface, but in the area that has no
sensitive magnetic material. This allows the drive to start the motor to the required speed.
In order to replace the heads on these Seagate hard drives, it is required to transfer
the heads over the “data” area on the platters and then slide them off the platters so they
could be removed. After this, when installing the donor heads, they need to be “lifted” on to
the platters and then slid over the platters to the “parking area”. This procedure requires 2
types of contact: contact between heads and platters, and contact between the heads
themselves. During these contacts, both platters and heads could get damaged.
By using HddSurgery
TM
head change tools both these types of contact are
eliminated. The purpose of HddSurgery
TM
head change tools is to ensure a safe passage of
heads over the "data area”, and to provide a non-contact transfer to patient disk.
HDDS Sea 7200.12/.11/.10+ p1 Set
This set of head change tools is made for safe and easy head replacement on Seagate
7200.12, 7200.11, 7200.10, SV35.5 and LP, but also Maxtor DiamondMax 23, DiamondMax
22 and DiamondMax 21 hard drives with 1 platter. The package contains 2 tools: for drives
with 1 platter and 2 heads, and for drives with 1 platter and 1 head.
During the whole procedure of head replacement, there is no contact between the
heads and platters or between the heads themselves. Heads are lifted above the “parking
area” and then safely guided over the platters. Same procedure needs to be done when
installing back the donor heads. Heads are guided over the platters and then safely
deployed in the “parking area”.
