If we don't you might loose the Harddisk. If it is still writing data to the disk the disk might be corrupted.
Besides that, your OS is most likely running from it. You might also cause physical damage to the PC itself.
Just shutdown your PC and then replace the HDD.
A person should use disk defrag weekly to keep computer from slowing down but you only have to do it when it does slow down.
Yes
Upwind = tack, Down wind = gybe
While it's running, yes. It will not slow down you computer unless you are actively using it.
i think it is because you are planned a disk check in drive property or the drive or disk have a defect, otherwise because of a virus
No. Watching a movie, no matter if it is a DVD, an online movie or even one that is stored on the hard disk, will utilize the hard disk just like many other applications. As such, there is some amount of wear and tear, mostly to the ball bearings, and there is an increased risk of damage through excessive vibration and shock while watching, compared to the computer being shut down. This wear and risk is no different from any other computer use, so no, watching a movie does not reduce hard disk life more than any other computer usage.
There are 2 types of memory on a computer. The Random Access Memory or RAM is like the workspace you do things on. The other type of memory is the Hard Disk or HD is like a storage room where everything you will need is put away until you need it. RAM is cleared every time you re start the computer or the computer is shut down/ turned off. The Hard Disk lasts for many years and if you what to clear that you will loose everything on the hard disk. That clearing is done by using the install disk to reformat or completely erase the hard disk
you have to go to the start button on the side where it says your user you scroll down to computer and click on it on the side you should find the C disk and click on it
a computer is to remove power from a computer's main components in a controlled way. After a computer is shut down, main components such as CPUs, RAM modules and hard disk drives are powered down, although some internal components, such as an internal clock, may retain power.
rapidly changing gears in anything will hurt the vechicle but not slowing down will not
There are several reasons why the computer got frozen/ not working or hanging up. One of possible reasons are 1.virus -some of this are deleting files and reduce the performance of the computer. Once the virus is loaded in the main memory it's affect the speed in accessing data in the computer.2.Worm-worms,its occupy the disk space that sometimes if the disk space is occupied it slow down the speed of the computer.3. Users-sometimes the way we use can cause computer to hang or get frozen. Multitasking or opening of a 1 software at the same time can slow down the computer operations.We can compare it to ourselves eating while mouth is full is not good,we chew the food while putting another food while our mouth is full.
The shut-down command.
