If the device is being disabled by Windows to save power, you can disable this feature.
A: Yes. In Device Manager, right-click the unknown device and select Disable device . This will stop the error message and free up a small amount of system resources. You will lose SD/microSD card reading functionality.
Carefully crack open the plastic housing of the USB drive to expose the circuit board.
Because Alcor Micro updates its firmware libraries constantly to support newer NAND memory wafers, there is no single file that fixes every device. You will need the tool suite.
Find the NAND flash memory chip (the larger rectangular chip).
Reflashing firmware via AlcorMP is a destructive factory-reset process. It clears the translation layer of the controller and runs a low-level format across the NAND sectors.
Because Alcor Micro produces components for other companies, the best driver is usually found on the laptop manufacturer’s support site. Search the Lenovo Support site

Once your Alcor Micro drive completes the flashing cycle successfully, confirm that the hardware is stable. Download the tool and perform a complete write/verify cycle. This test writes mock data across the total volume to confirm that the drive holds its full capacity without corrupting files or hitting bad sectors. Share public link
This is the specific firmware version installed on the controller.
: Select Capacity Optimize to rescue the maximum available space, or Speed Optimize if the flash cells are heavily degraded.
Visit specialized flash drive repair archives like USBDev or FlashBoot. Search for the specific Alcor controller part number you found in Step 2. Download the AlcorMP version that explicitly lists support for your firmware generation (3613) or your Flash ID. 2. Configure AlcorMP for Recovery
