I worked with a Dell agent online last night to help me create a USB to save original factory settings in case i ever need to reload the Windows 8 operating system. After hours of formatting the USB stick i have, it still wouldnt work. She said she would send a "DUSB"....what is a "DUSB"? Today I got an email saying i was being sent "replacement parts". I thought a DUSB was just a USB stick with the OS loaded on it for me to keep and use if necessary to reset my computer to factory settings.
