A) your USB key is flakey

B) your systems USB ports are flakey

C) the cabling between the mainboard and the USB port is flakey.

I've run into C) quite a lot, where front panel USB ports don't work 
reliably at USB2.0 speeds when doing large and/or complex operations.  I 
suspect the internal wiring is inadequate for the task.
