What is a removeable hard drive?

Answer 1

Hi,

All hard drives can be removed. Normally Hard disks are connected inside the computer to the computers main circuit board called the Mother board. They connect to the IDE connection point using IDE(Integrated Device Electronics) cable. Since the box must be opened to take these out they are considered non removable. Removable Hard disks connect to the computers USB (Universal Serial Bus) point outside the box making them easy to put in and remove. The device themselves are the same. They are like old record players. They are a series of metal disks called platters stacked one on top of the other that take electric charge to store data. Not to be confused with Memory sticks that also act like Hard disks. These are really just Memory modules with batteries to prevent them losing information when you take them out of the computer. Memory modules (Ram) are your computers short term memory (Thinking power). When programs run data is not stored but short term memory is enabling all the functions that are happening in real time like calculations and what you see on the screen are stored. Hence when you turn off or get a power cut these short term things are no longer as the ones in the computer dont use batteries to make the information more permanent. Hence why Memory sticks are not proper hard disks. Because a loss of power to the printed circuits and chips means Information loss. But with a Hard disk you can send the disk away to a specialist to take the platters apart and read the physical changes in the platters to be read. Information recovery. Hope this was'nt too long winded & i hope it was helpful Michael

A removable hard drive is hard drive that you plug in with USB plugs to your computer, and it acts like a hard drive. It can be unattached an attached easy and they are small enough to carry around, so it's like a very big memory stick.
