Computers Run On Hard Drives
A computer cannot run without a hard drive. Hard drives store all the data the computer needs to be up and running, like the operating system, commands, and executions. Program files are also stored on the drive and so are personal computer files.
A hard drive is very fragile. The disc inside is always spinning when powered up and can be damaged if dropped or if something magnetic is close to it. It can be erased if that happens.
Anywhere from a hundred to a thousand gigabytes of space are on hard drives. A thousand is called a terrabyte. It depends on what types of files the user has. If it’s a photo collection or music they may only need a few hundred. Graphic designers will likely need much more.
An internal hard drive stays inside the computer, while the external type is stored outside. Internal ones are for the computer to run on, while external is more for extra storage space and backup. They can be hooked up by USB cord.
Hard drives do have a life, and after some years will grow old and die. Though some may last for many years, some may only last a year or more, depending on the brand and the workload of the drive. They do need to be replaced after some time though, so be sure to have two places to back up your data in case of failure.
A good way to take care of your hard drive is to perform maintenance every so often, such as defragmenting. This deletes old and obsolete file fragments that are cluttering up the drive and will free up space and memory.
A drive can also be reformatted which means it is wiped of all data and can be started anew. This erases all previous data, however, and anything else that is stored on it. Be sure to back up first before doing this.
