HDDS Sea 3.5” Ramp Set is a set of head replacement tools (Head Combs) which can be used to safely and easily replace heads on almost all new 3.5” Seagate hard drives which “park heads” on a ramp:
This set contains 6 pairs (12 pieces) of head replacement tools: Sea 3.5” Ramp p1, Sea 3.5” Ramp p2, Sea 3.5” Ramp p3a, Sea 3.5” Ramp p3b, Sea 3.5” Ramp p4 and Sea 3.5” Ramp p5.
These head replacement tools are used to ensure that the heads do not touch each other in proces of replacement and to enable their easy mounting back to the ramp.
These tools don't solve the head compatibility problem. They will only assure that the process of head replacement goes easily on supported drives.
