Yes you have bought a fake drive which has been doctored to trick your computer into showing a huge 16gb capacity when the true capacity is only 1gb.
in use it will be very slow as it pretends to be saving all of your data.
So to sum up you wont be able to get your 15gb of lost data back, because there was not really any free space there for it in the first place!!
