When a device is plugged into the system, what happens is dependent on what the device is, and what its capabilities are. If you plug in a USB HUB, it will not appear anywhere. If you plug in a camera, it depends on whether the camera has a file system that can be read by the computer. If you plug in a printer, it will appear in the system prefs under printers. It won't appear on the desktop. If a hard drive or memory card or thumb drive has a readable file structure, it will appear on the desktop. So, what happens depends on what is connected to the system. Just plain old thumb drives usually work fine in any computer.

After you are done installing the system, you can connect the other drives again and not having the 200 mb partition.
Bootable devices are pieces of hardware that the BIOS can load an operating system or special program off of. These can be floppy drives, CD drives, hard drives, USB flash drives, tape drives, SD cards, and certain ROM chips.
