If your drive has fallen victim to this glitch, your data is locked, and the drive is bricked. Fortunately, a SM2259XT firmware fix is entirely possible using specialized Mass Production Tools (MPTools).
Configure the drive settings (set the target capacity, vendor name, and serial number if desired). Return to the tab and click Start (or Spacebar).
Fixing SM2259XT firmware is not a click-and-run process like updating a graphics driver. It typically requires entering the controller’s ROM mode (often achieved by shorting specific test points on the PCB), which forces the drive into a low-level state where it can accept a new firmware image. The most common tools used are or SMI Debug Tool , which were originally designed for factory flashing. sm2259xt firmware fixed
