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.

Do not unplug the drive until the box turns green. If it turns red, an error code will appear for troubleshooting. Troubleshooting Common Errors
This is the most generic error, meaning the process failed. It’s commonly caused by incorrect firmware selection. Double-check your Flash ID in GetInfo and search for a more compatible BN/FW file pair. Try the UPTool (e.g., v2.093), which is sometimes more effective for “black chip” (low-quality) NAND flash.
This is the most common hang-up. Your PC needs to see the controller before it loads any driver. Here’s the trick:
