I am absolutely positive it was plugged in properly, and i am also sure the usb port isnt broken, i have tested all of them, though, this is first time i have had so many in use concurrently, maybe its a power issue? (which would be weird though, as flash devices shouldnt be using so much power)
as for faulty, i did use that exact drive again, when i reverted back to doing one by one.
