The operation is not supported on removable media. <— USB2 is intented for external hard drive/ portable hard drive only. (warning all data on your portable drive will be erased) so please make backup first.
you will need a USB hub with AC power to provide enough juice for the external hdd.
take caution, when i installed fresh windows 8, the diskpart accidentally remove my android partitions, i don’t know how it happened.
now my android is gone, but i can live with it, more space for windows, 16GB free !
