This section describes the drive mechanism. Section 5.2 describes the drive
electronics. The Maxtor D540X-4K hard disk drives consist of a mechanical assembly
and a PCB as shown in Figure 5-1.
The head/disk assembly (HDA) contains the mechanical subassemblies of the drive,
which are sealed under a metal cover. The HDA consists of the following
components:
• Base casting
• DC motor assembly
• Disk stack assembly
• Headstack assembly
• Rotary positioner assembly
• Automatic actuator lock
• Air filter
The drive is assembled in a Class-100 clean room.

To ensure that the air in the HDA remains free of
contamination, never remove or adjust its cover and seals.
Tampering with the HDA will void your warranty.
