ok so actually i now put back in the flash drive and it showing now lol....

past few days it wasn't showing but it seems like it working now
Might have simply been dirty contacts on the flash drive or port... light rubbing with a clean pencil eraser or several insertion/removals can clean the contacts resulting in what you experience!

Simple solution, if possible... Format your flash drive on the MAC using a Windows compatible format.
