Some FA00/FA04 devices appear as a CD-ROM (fake) first. That is mode-switching. To make it work:
This process will completely erase all data on the USB drive. It cannot be used for data recovery.
Technical reviews and community discussions suggest the following regarding these specific identifiers: alcor micro unknown fa00 f w fa04 work
: Reflashing firmware using mass production tools like AlcorMP will permanently delete all data on the drive.

Download a trusted flash diagnostic utility like (Version 4.21 is highly recommended for accurate Alcor detection).
If your software tool displays and a false size of 0 Bytes , standard flashing tools will not detect the device properly. You must force the Alcor controller into its baseline hardware Test Mode before opening any software. It cannot be used for data recovery
To resolve this using (Mass Production Tool), follow these specific actions: Configure Driver Settings : Open AlcorMP and locate the Driver button.
This specific combination signals that your flash drive's microcontroller has lost its pathing to the NAND flash memory, tricking the computer into thinking it is empty. To fix this, you must bypass standard Windows software and use a low-level to reprogram the controller. Understanding the Technical Anatomy of the Error
