After you upgrade to Microsoft Windows XP Home Edition, the floppy disk drive may not appear in the My Computer folder. In Device Manager, the device status for the Floppy Disk Drive returns the following error message:
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
This behavior occurs because the SmartDisk FlashPath Monitor from Synchronized Technologies, Inc. is installed. When you start the computer, this program typically loads automatically and changes the registry settings that belong to the floppy disk drive.
