Procedure:
I had a 64GB Corsair Flash Voyager that showed "Please insert disk" in Windows. After identifying the controller (Phison PS2251-07) using GetInfo or ChipGenius, I downloaded MPtool v3.78. The first three versions didn't detect the drive. Version 3.81 did. I spent 45 minutes matching the flash ID (98 DE 94 93 76 D7 – Toshiba TLC). After editing FC1.ini and FF.ini, clicking "Start" rebuilt the drive in 12 minutes. It worked, but I lost all data. I'd rate the success rate at about 60% for first-time users. PS2307
