This tool only works on an Indilinx drive (Agility, Vertex, Solid2, Onyx) it does not work on Sandforce (Agility2, Vertex2, Vertex-LE, Vertex2 Pro) This process does not require a jumper, you simply boot to your USB Stick and run the program. This process does require you to be in IDE mode, AHCI mode will block the utility from seeing the drive. THIS PROCESS WILL NOT WORK WITH JUMPER FITTED OR IF THE DRIVE SHOWS IN ENGINEERING MODE AS A YATAPDONG DEVICE
