What are the body parts of hard disk drive?
The hard drive, which typically provides storage for data and applications within a computer, has four key components inside its casing — the platter (for storing data), the spindle (for spinning the platters), the read/write arm (for reading and writing data) and the actuator (for controlling the actions of the read/ …
How does a hard disk work?
The hard drive contains a spinning platter with a thin magnetic coating. A “head” moves over the platter, writing 0’s and 1’s as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0’s and 1’s.
What is the hard drive similar to in the human body?
HARD DRIVE = BRAIN – Subconscious All knowledge of programs, files and data is stored on the Hard Drive. Just like the brain, it is sectioned off for various purposes. The hard drive stores and retrieves all of our precious information and programs for use by use whenever we wish. Just like our long term memories.
How is the human body like a computer?
Just like your skeleton does for the body, the motherboard is the main structure of a computer and holds everything together. The motherboard can also be seen as the nervous system because it connects to various parts of the computer and by connecting something to each part something different happens.
What happens if you shake a hard drive?
Yes. Excessive vibration, shaking, shock, and impacts can damage the hard drive. At the very least you can bounce the read head against the surface of the platen inside the drive and physically damage the surface.
What are hard disk platters made of?
The platters are made from a non-magnetic material, usually aluminum alloy, glass, or ceramic. They are coated with a shallow layer of magnetic material typically 10–20 nm in-depth, with an outer layer of carbon for protection. For reference, a standard piece of copy paper is 0.07–0.18 mm (70,000–180,000 nm) thick.
How can I clean up my hard drive?

What is the RAM like in the human body?
The motherboard. The motherboard is the main structure of the computer similarly to the skeleton is the main structure of the human body. The RAM. The RAM is a hardware which has the role of short-term memory of the computer; similarly the pre-frontal lobe in the brain plays the role of short term memory in the body.
How the human body is like a computer?
How many GB of RAM does the brain have?
Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).
Is your brain a computer?
The brain is a biological organ, and not a digital computer. Neuroscience has discovered that while the brain mediates between the body and the environment, it does not command the body.
How do you permanently erase a hard drive?

Click Next, then choose Fully clean the drive to ensure everything is deleted. Click the Reset button and your drive is wiped, your PC is reset, and Windows is reinstalled.
What liquid will destroy a hard drive?
Melting hard drives involves dipping them in acid to destroy their platters and housing. Although this is one of the most effective hard drive destruction methods, it is also one of the most dangerous. This is because the process involves using hydrochloric and nitric acids.
Can a hard drive survive being dropped?
Drops can render head crash in the hard drive. It means that the drive heads will get close to the drive platters and lastly drive will be unable to work any longer. When a hard drive fails, its internal data will be at risk as well. Hence, it’s always suggested that users should take good care of their hard drive.
Why do hard drives break so easily?
Because external hard drives contain moving parts, this makes them more susceptible to physical damage. If you factor in the portable nature of external hard drives, the chances of a physical fault like a head crash or motor failure occurring are higher.
