How Does an External Hard Drive Work?
As the name implies, external hard drive uses hard disk drive as its storage media. Compared with internal hard disk drive on computer, external hard disk drive is connected to a computer via USB cable while hard drive is connected to a computer through IDE. Both hard drive and external hard drive are used to store data. External hard drive can also be used to transfer data because it can be easily unplugged out from one computer and be reconnected to another computer.

worked as an internal hard drive but it must be connected with the computer
through USB cable. However, for some reasons, an external hard drive may not be
recognized by computer after connecting it to the USB port.

Other Causes for External Hard Drive

If the front USB port on case of some
low-quality mainboard is short of power supply, the external hard drive will be
unrecognized by computer. In this case, you can connect the external hard drive
to your computer through back USB port. The external hard drive will be
recognized normally if you can ensure the enough powerful supply and data will
not be lost from the drive.

to be lost and might be unrecoverable. Therefore, you had better spend a little
more money buying a good-quality external hard drive.
