If I understand what you are saying then the reason for that is that the hard drive may be damaged when you need to use it or it can not be read properly
The first two floppy drives, if present, are A: and B:. Then, the first active partition on the first hard drive is C: If there is a second physical hard drive, it would be D: ... additional partitions on the hard drives, if active, would get letters after that. The optical drive is normally lettered after the last hard drive partition. So, if you have a computer with 1 floppy, one hard drive with a single partition, and a CD Rom drive, the floppy would be A:, the hard drive would be C:, and the CDRom would be D: In more recent operating systems, however, you can re-arrange drive letters using the storage management tool; but the above is the "normal" arrangement.
That would be your hard drive since it holds your operating system.

you would rather drive there
If you can, open up your computer and take the hard drive out. I would then take it to a computer store and have them transfer the data (If possible) to another hard drive.
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.
No it is not, the closest relation to a brain in the computer would be the Hard Drive and the CPU
There is software you can buy to add a Blu Ray drive to your computer. However, many software systems are only compatible with specific computers, so you should figure out if the one you want will work with your computer.
IDE 0 always has the designation C. Its a throwback to the days when computers were single or dual floppy drive only and they had (and still have) designations A and B. Hook up the external drive, go into the BIOS and select the external as the drive to boot from. Save the change and allow the computer to boot. Load the OS and it should defer to the external drive.
Computer viruses only affect the memory of your computer. Say you get a virus and your computer will not let you open programs. You would need to get a new hard drive or wipe all data from the hard drive, and then reinstall programs.

it depends on what kind of computer you have, butreally you just would open the computer case, then unscrew the hardrive from the bracket and there you go.
