We probably never have to break down our hard disks to see what is inside or to fix it, except if some of us become computer engineers. But it is essential to know some basis of the HDD anatomy, so we know how to treat it. And to know the connecting slots is
useful even in everyday life. Here are the included HDD parts.
1. Actuator. An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve.
2. Actuator Arm. An actuator arm moves the heads on an arc across the platters as they spin, allowing each head to access almost the entire surface of the platter as it spins.
3. Read / Write Head. Disk read/write heads are the small parts of a disk drive which move above the disk platter and transform the platter's magnetic field into electrical current (read the disk) or, vice versa, transform electrical current into magnetic field (write the disk)
4. Spindle. The HDD's spindle system relies on air density inside the disk enclosure to support the heads at their proper flying height while the disk rotates.
5. Platters. A hard disk drive platter is the circular disk on which magnetic data is stored in a hard disk drive.
6. Debris Filter. Some hard disks have filters to keep the Platters clean
7. Interface Connector. Older type connection with the mainboard
8. SATA Connector. Modern type connection with the mainboard
9. Power Connector. This goes to the PSU.
10. Jumpers. In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. Basically we can make teh disk primary or secondary with jumpers.
11. Frame. The metal frame that holds the hard disk.
