Alcor Au6370 Driver Windows May 2026

If you are downloading the driver to repair a corrupted flash drive, simply installing the driver is often just the first step. You will likely need the AlcorMP (Mass Production) Tool.

The Alcor AU6370 is a highly integrated USB 2.0 Flash Disk Controller chip manufactured by Alcor Micro Corp. It is commonly found inside USB flash drives, external hard drive enclosures, and memory card readers.

If you have plugged a USB device into a Windows computer and found that it is not recognized, or if you are attempting to "re-flash" a corrupted USB drive, you may need the specific AU6370 drivers and utility tools.

Warning: Using the wrong settings in AlcorMP can permanently brick your USB drive. Always backup any accessible data before attempting this.

If your device is not being detected, follow these steps in order.
