What is Hard Disk Drive (Know Details)
Hard disks are essential components of computers. They store data and provide access to files and programs. If they fail, then your computer won’t function properly. Hard drives come in various sizes and capacities, from 2GB to 128TB. The larger the capacity, the more expensive the price.
When a hard disk fails, it might seem like a simple fix. However, repairing a hard disk isn’t always straightforward. There are several steps involved, such as removing the old hard disk, installing the new one, and testing it to ensure that it functions correctly. A hard disk has two parts: the platters and the heads. The platter contains magnetic material that stores information. When you turn on your computer, the heads read the information from the platters and write new information onto them.
You might also hear the term RAID (Redundant Array of Independent Disks). This refers to multiple hard drives working together to increase performance and reliability. Hard disk failure rates are high, so having backups is important.
The head reads and writes information by moving over the surface of the platter. It uses an actuator arm to move back and forth across the platter. A motor rotates the platter at high speed, causing it to spin. The platter spins at 7200 RPM in most cases.
