No...absolutely not. You can remove all sources of power to a PC and the hard drive will retain all information saved on it. You could even go so far as to remove the hard drive from the PC (always with caution and extreme care) and hook it up as a slave to another PC and still view files saved on that hard drive.
when any kind of information is received to you in any way weather hard disk or soft disk is known as output device .
I'm not sure exactly what the question is. If it loads Windows, obviously the hard disk WAS detected. Still, it may be a faulty motherboard or a failing hard disk or a corrupted installation of Windows or something. You may want to get it checked out by calling tech support.
Raid 1 suppports the Mirroring if any one hard disk faild one will get the copy of the data and fault tolerent. after replacing the hard disk you have to re create the mirroring.

On a desk top, it connects power from the outlet on the wall to the power supply in the computer. On a laptop. It converts the mains AC power at high voltage to a low voltage DC. Most laptops use around 19v DC. This is then used to charge the battery in the laptop. When the battery is full, the laptop is then powered by the mains supply, leaving the battery in standby. On a desk top the power supply is inside the cabinet. On a laptop it is separate. This saves weight and space when using the laptop totally portable and running on battery

Information is stored in the computer's hard drive, which is a magnetic disk read by lasers.
A hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile, they retain the data even when they do not have power.

Some games require that the game disk be present in the drive to play. Other games do not require this. The only way to circumvent the need for the disk to be present is to go on the internet and search around for a cheat that will allow the game to be played without the disk.
In the drive mechanism the part that does this is the head assembly.
