don't leave cd's and floppys in the drives if they are important.
Create a Windows XP forgotten password floppy disk
You need some form of boot disk - a floppy of DOS, a Windows boot floppy, a bootable Windows CD, and sometimes Linux can be used to make a plain MS-DOS 16-bit fat) partition.
Every version of Windows, even Vista, bundles a copy of MS-DOS. You can create an MS-DOS boot floppy by formatting a floppy disk, and checking the "Create an MS-DOS startup disk" box.
If you know the password, go to the control panel, click the User account and Security, in the left panel, there is a option to Create A Password Reset Disk, insert a USB drive or Floppy drive, now you can create a password reset disk. If you forget the password, you can use other tools like Windows password Unlocker to create a password reset disk, see a tutorial here: http://www.passwordtech.com/how-to-crack-windows-7-password.html
No
There are no partitions in flash memory that is used in USB port or floppy drives. Usually windows will not allow you to partition these. A CD-rw, which is a CD that can be erased and re-written, can not be partitioned. These can not be partitioned in a sense that they will create two separate drive letters. There is some software made that will partition a flash drive, but it might void the warranty unless it is allowed by the MFG.
My Computer, right click on floppy drive-> Format... In the next windows choose Create a MS-DOS startup disk
As with all Microsoft Operating systems, they can support a maximium of 23 drive letters. This is excepting A & B for the floppy drives (old DOS support) and C for the first primary hard drive.

The computer management feature in Windows can be used to partition a drive and create logical drives within these partitions. There are also commercial and non-commercial programs available for the same purpose.
USB is a standardized bus for connecting exernal peripherals (printers, scanners, keyboards, mice, flash drives, hard drives, etc...) to a computer. A floppy disk drive is an outdated method of storing data. It uses a thin sheet of coated plastic, usually inside a firmer plastic shell, to store data.
The similarities depend on the platform. But generally the only similarity is they are drives in a drive letter access system. On Wintel machines that had them back in the day, A was the designation for floppy drives and C was the designation for the first hard disk. Keep in mind that how a drive is actually exposed to the user is entirely up to the operating system. While Windows will have an A: C: D: drive, etc. Linux allows access to them by mounting their device files right on the directory tree and there ARE no drive letters. For example, a floppy drive is likely going to be /dev/fd0. One can insert the disk, then as root: mount -t vfat /dev/fd0 /media/floppy (Assuming there is a directory /media/floppy.). Then you can just change to that directory using a shell or file manager and access it as if it were just any other subdirectory on your filesystem. Today floppy drives are nearly extinct. The high dendity floppies we had just a decade ago just plain don't have the capacity to be useful, and with DVD-RW and flash media being the standard removable media there's no motivation to create a "new floppy."
