Hello listers: I've seen messages herein the past advising other listers to run the check disk utility while the Braille Plus or Icon is in disk drive mode as a way to figure out what could be wrong with the device when some problems arise. Does this utility come with the unit? I notice that I can not invoke it while the Braille Plus is in disk drive mode and connected to my PC as my windows xp system doesn't have it, and it appears the unit doesn't have it either. How would one get this utility? Marta
