Self-Extracting Firmware Files
If you have installed IAA (Intel Application Accelerator) in your PC, the firmware update for PX-750A may fail during installation, resulting in failure of the drive. If IAA is installed, please uninstall it before running the Plextor firmware updater. In case of failure, please run the firmware upgrade again after uninstalling IAA and rebooting the drive.
You can uninstall IAA through "Add or Remove Programs" of the Control Panel.
