Help me pls, data storage device error/damage - Flash drive

I bought an original 2GB DataBar flash drive two years ago and i have been enjoying it ever since until today when i inserted it into a computer and the OS saw its memory size as 120KB, practically empty. I checked further and noticed 0kb memory space due to an absence of physhical partition. What do i do to revive it? I already did somethings i tot would work but all to no avail. Things like formatting, trying it on different computers, scandisk and so on but it still remained the same. It's really urgent, pls help.
