Hope this helps leave a comment if you lie the article.
The hard drive is not included. This is just an enclosure. Once you add a drive and plug it into a USB port, It would show up under my computer as a drive letter.
drive letter of an USB drive can be any letter from E to Z, It also can be D if you don't have DVD drive connected to the computer &C is the hard-disk drive needed for the Windows. It depends on the hard disk partition you had made.
Hard Drive, USB, thumb drive.
Assuming your Compaq laptop has a USB port or two, just plug in the new drive with the USB cable. It will show up as another drive, using the first available drive letter, in Windows Explorer (or equivalent).

You can use your laptop to back uup your hard drive but your USB is not the thing getting backed up.
It depends what you are copying them to. If you are copying them to another hard drive, it will have a different drive letter. it is the same with USB drives.

No it will have no effect on the life of the mechanical hard drive, the only difference is that the full speed of the USB 3.0 device data transfers (5 Gbps) will not be available, data transfers to and from the hard drive will happen at the slower USB 2.0 speed (about 0.5 Gbps).

Sometimes USB drives are not fully recognized by a computer. First, check under My Computer. If the drive letter shows, try stopping the drive first. If no drive letter is there, you can safely unplug the USB cord, wait a minute or two, and plug it back in. Let the USB drive run through, do not hit cancel. If it never recognizes, you may need to restart your computer with the USB cord not attached, and once Windows finishes loading, plug in the drive and try again.
Each hard disk can only have one Drive letter. You can't have two drives labeled "C" for instance. However, if you are asking about a USB device getting the same letter, then the best way to make sure you get the same letter is to keep that device always connected. Once you disconnect such device, then all bets are off. Say that you have for example an external hard drive (assigned to F) and a USB flash drive (assigned to G). If you disconnect them both and tomorrow (or even today) you connect the USB flash drive first and the hard drive next, then the flash drive will get the letter F and the external hard drive will get the letter G. This is based on the fact that the computer assigns letters based on what is already connected and goes down the alphabet in order from there on regardless of what you connect next.
