i have tried this. it pops up " the drive is write protected"  the drive worked perfectly, i never disconnect it from the computer without “safely removing hardware”. if i loose the information on the drive it wont be the end of the world. i just  want it to work again. im pretty sure i dont have a warrentee anymore since its been over a year.
