Improved products and new products:

HDDOR ST 2.5” Ramp Set is a set of head replacement tools which can be used to safely and easily replace heads on most of 2.5” Seagate hard drives which “park heads” on a ramp. Set contains 5 of head replacement tools: ST2.5” Ramp p1, ST2.5” Ramp p2a, ST2.5” Ramp p2b, ST2.5” Ramp p3 and ST2.5” Ramp p4.

ST2.5” Ramp p1

This head replacement tool can be used on 2.5” Seagate hard drive model Momentus Thin with 1 platter.

ST2.5” Ramp p2a

ST2.5” Ramp p2a head replacement tool can be used on the first type of Seagate 2.5” hard drive mechanics which includes models 4200.2, 5400.2, 5400.3, 5400.4 and Momentus PSD with 1 or 2 platters.

ST2.5” Ramp p2b

ST2.5” Ramp p2b head replacement tool can be used on the second type of Seagate 2.5” hard drive mechanics which includes models 7200.3, 7200.4, 7200.5, 5400.5 and 5400.6 with 1 or 2 platters.

ST2.5” Ramp p3

ST2.5” Ramp p3 head replacement tool can be used on older 2.5” Seagate hard drive model FreePlay which has 3 platters. These hard drives usually came in external FreeAgent Go casings and had capacities of 750GB or 1TB.

ST2.5” Ramp p4

This head replacement tool can be used on new 2.5” Seagate hard drive model FreePlay with 4 platters and 7 or 8 heads. These hard drives usually come in external FreeAgent GoFlex casings with capacities larger than 1TB.

They cannot solve incompatibility issues. They can only support hard disk drives, with easy and safe head replacement.

Head replacement tools (head combs) offer a safe and easy way to replace the magnetic heads of hard disk drives. These tools can ensure a non-contact head replacement.

That means there is no contact between the heads, or between heads and platters when you disassemble donor heads and install heads on malfunctioning hard disk drives.

Heads can be transferred from donor to malfunctioning hard disk drives in a few easy steps. During the process of head replacement, heads do not touch each other or make any contact with the platters. Each head change tool is designed for specific brands and models of hard drives, and these tools are not generic since mechanics of different hard drives doesn't match.

These tools offer as one-piece, not as a pair.

Supported models:

The list of tools may be updated as we get information from the market. HDDOR isn’t responsible if the producer change the architecture of a drive from the list above.

HDDOR ST 2.5 Ramp Set

Most of supported Seagate hard drives don’t have a definitive way to determine the type of mechanics only by their model name. Because of this, we will present a list of Seagate hard drives supported by the whole set.

*Due to the large diversity in 2.5” Seagate hard drive mechanics, some tools will have a limited function on some

models of these hard drives. Limited function will mean that the securing pin couldn’t be used because the hole

for it on the head arm has a slightly different shape or position.
