Blue Thunder (ThumbDrive) Problems

I just Buy This ThumbDrive few weeks ago

But Yesterday My Devices not work very well
I thought only computer mistake (cyber cafe)
but after change to another computers few times still get the same result

i try to go on troubleshooter but all my device did work properly
and most weird is after attach my device to USB pot he said that “device ready to use”

But when i wait about 5second the pop up section dint show up

After check to “my computer” i see my device been replace by "Removable Disk (E:)

Many Kinds Of Search have i done but all The problems Seem Not Likely Mine…Hope u guys can helps out~ :sad:
