hi all, i'm back with a new problem again:grinthumb:rolleyes: when i connect my thumb/pen drive or my mobile to my machine through USB port, some times it gives me a problem while safely removing. it says "this hardware cannot be stopped now" or something similar message pops out. is this because of any virus or any problem with my USB port? can some one explain why this is occurring? this thing happens once in a while not a frequent problem!
