Random Access memory (RAM). It only holds data while the computer is powered up.
It is the Random Access Memory (RAM) that is a volatile memory. Unless the data is saved to the hard drive before switching off the computer, the data on the RAM will be lost.
RAM (Random Access Memory)
ROM
Because any data written to a hard drive will be retained almost indefinitely after the power is removed.

You will only lose data during the duration your hard drive is removed. As soon as you reconnect it your data will be restored.
A hard disk drive (HDD) is neither an input nor an output device. It is a Storage Device. It helps to store the data in a Non-Volatile form (i.e Data stored in Hard Drive is not lost even after it's power source removed) and data can be retrieved at any time by enabling power for the Hard Drive.
The HDD, or hard disc drive is one example of a drive that does not require power to hold its stored data.
An internal hard-drive fits into a bay inside the computer's tower. A power cable from the power unit is plugged into the hard-drive. A data cable plugs the hard-drive into the motherboard.

Data held on the hard drive, is considered to be permanent. It will still be there, after the power has been removed for many years. Random Access Memory (RAM) is the working memory, held on microchips and needs power to keep the data. It will be immediately lost when the computer is switched off. This usually of little consequence as important data is always held on the hard drive. The RAM is only used for temporary data whilst working.

If you want an example, all 'RAM' (Random Access Memory) is volatile - once power is removed the data is lost. Compare this to a CD or your hard disk drive.
No, hard drive is a non-volatile device. Volatile memory devices store data temporarily and lose data on power cut. However hard disk retain its data and hence is non-volatile memory.
Yes, Surely it will remove everything on hard drive. Formatting a hard drive means to remove everything on hard drive. If you are formatting only a specific drive like C:\ or D:\ then the data in only that drive will be removed.
