no one hard drive is "safer" than any other. I'll give an example. in the external's case, if it falls or is dropped at any time (especially while running!) it can and probably will cause damage to the data. for internal, it's usually the amount of use and age that does them in, but sometimes viruses, shock (power surges destroy anything not protected), or dropping the computer.
An internal hard drive will generally be faster than an external one.
There are external and internal hds
without a hard drive your PC wouldn't work at all. so you must have a hard drive, whether its internal or external...
No, you have to also delete what you want from the external hard drive. Remember, an external hard drive is just like a internal one. So, for example, if you delete picture a on the internal hard drive, that's all that is deleted. If picture a is also on the external hard drive (why would it be though), then you need to also delete it there.
Most external hard drives can be used as internal ones. Provided that the IDE, SATA, or SCSI interface of the external hard drive is the same as the desktop's system board hard drive interface. Users can remove the USB casing and proceed to plug the data and power cables into it. The external drive, just has an additional component, that's used to hook up with the USB port.
They make internal and external 500 gb HDD
You can safely name external and internal hard drives whatever you want on a Mac.
Generally speaking yes, but consider that hard drives can be either internal or external. It's like asking "Is the apple the same as the fruit?"
No, they don't disappear, unless you use the command move to...
Just click and drag.
Well as you may know an internal hard drive is inside your computer and stores just about all your computers' info. But you may have information on there that you want to take to your friends house, so you would put the info on your internal hard drive on an external hard drive, then put it on your friends computer instead of taking in and out your internal hard drive. So really bottom line here and external hard dirve is a more portable hard drive and easier to carry around.
It depends on your needs, but internal drives will be cheaper and more reliable.
