Correction: the "A" Drive is a floppy disk dirve that holds, reads and writes on the floppy disk.
CD drive, floppy disk, disk tray.
Normally a floppy drive interface can be used to connect two floppy disk drives. However this may vary from system to system, some systems may also have two interfaces. It may be necessary to purchase a floppy drive cable with two connection headers.
The only floppy drive system commercially available today is the 3.5" floppy disk drive. Previously there were both 5.25" and 8.00" disks/drives also available for PC's.

The best way to disable a floppy disk drive is to disable the floppy interface from the system BIOS. This should remove all traces of the floppy disk drive to the operating system. It is also easier to reverse should the disk need to be enabled again later,
The drive might not be recognizing the floppy disk. Start up your computer, and go to the BIOS menu (usually you have to press f2 or f3), and make sure the optical drives are enabled. Also consider using a flash drive instead of a floppy disk.
That would be a floppy drive. Information is passed from the software and/or the operating system to the drive controller. From the drive controller, it is passed to the logic circuits on the drive and to the drive heads. The logic circuits also turn on the drive motor for an appropriate amount of time.
There are several guides online for formatting a floppy drive. WikiHow has step by step instructions with visual aids to complete the task properly. The website BleepingComputer can also help.

Secondary storage can be used to restore a backup of your files if you have to format. You can use it if you run out of room on your main hard drive. If it is external secondary storage you can also bring it with you if you need to access files at work or somewhere else. Commonly used types of secondary storage are the USB drive and Floppy Disk, as referred to in the joke 'Can you turn my floppy disk into a hard drive?' which is impossible!
Failed FDC means that the Floppy Disk Controller is no longer responding. Possible solutions to this issue are to replace the FDC (not so easy on integrated MBs) or possibly replace the floppy drive. This can also occur when the ribbon cable connecting the floppy drive is not inserted correctly.
Normally the second removable drive, A = first removable or floppy drive, if a second floppy drive is installed it is drive B. First hard disk is Drive C, second Hard disk is Drive D, etc. You can also map the drive letters to the virtual network connections, so that Drive P could be used as a network connection.
