You are trying to use an outdated version of AlcorMP that does not have the target database profiles or config definitions for newer FA00 chips.
This refers to the specific firmware version currently detected on the controller.
: Attempting to fix a drive with an incorrect or outdated version of the AlcorMP software tool can misconfigure the chip, rewriting its identifier into an unreadable state.

This is the manufacturer. Alcor Micro Corp. is a Taiwanese semiconductor company that produces USB controllers, card reader chips, and keyboard/mouse controllers. If you own a cheap or mid-range USB 2.0 or USB 3.0 flash drive, there is a high chance it contains an Alcor Micro controller (e.g., AU698X, AU699X, AU871X series).
: This indicates that the software tool can poll the Alcor controller, but the controller is refusing or unable to report its real hardware part number (e.g., AU6989AN, AU6989SN-GT). It defaults to the generic [FA00] hardware mask.
When a hardware diagnostic tool like or Flash Drive Information Extractor returns this error, it means the flash drive's controller chip is responsive but trapped in a generic boot ROM state. It cannot read the primary flash memory (NAND) configuration or load its standard runtime firmware. The breakdown of the technical signature is as follows: You are trying to use an outdated version
Alcor Micro provides a proprietary tool called (Mass Production Tool). This is a factory-level utility designed to flash firmware and low-level format Alcor controllers.
Keep the drive connected until the display box turns bright green, indicating success. If a red text error appears, note the error hex code (e.g., 0xE50B ) to find a matching version of the software on USBDev Support Forums . Phase 5: Hardware Test-Mode (The Last Resort)
Alcor Micro production tools are heavily chip-dependent. Because your drive reports [FA00] , it is highly likely built on an variant. This is where your actual data (photos, files,
Standard Windows tools cannot repair hardware-level firmware failures. Before downloading flashing software, you must gather the exact hardware identifiers of your controller using a utility like ChipGenius.
Standard Windows drivers will not fix a firmware-level "Unknown Device" error. You must use a "production tool" specifically designed for Alcor chips.
When the Flash ID (FID) reads as a repeating string like 89898989 or disappears entirely, the controller cannot talk to the memory chip. Windows will fail to format the drive, returning errors like "Write Protected" or "Please Insert Disk". Step 1: Gather Your Flash Drive Diagnostics
or similar variants. In a healthy state, these controllers manage the data flow between a computer and NAND flash memory. However, when the controller returns a status of "Unknown FA00" or "F/W FA04," it signifies that the device is in a bootloader or "test mode," unable to communicate with the internal flash memory chip. This is frequently accompanied by a "0 Byte" or "No Media" status in Windows Disk Management. Causes of "Unknown" Identification
