Identify the square controller chip and the larger rectangular NAND flash memory chip. Look closely at the rows of silver pins extending from the sides of the NAND flash chip. Step 3: Short the Pins and Connect Take a sewing needle or a pair of precision metal tweezers.
When AlcorMP displays , it means the software cannot identify the Flash ID (FID) of the memory chip. This happens for a few reasons:
Understanding and Fixing Alcor Micro Unknown [FA00] F/W FA04 Top Devices
The "Unknown FA00" error wasn't a hardware failure. It was an intentional lock. The chip had been programmed to look "broken" to any standard computer to prevent anyone from seeing what the station had found. alcor micro unknown fa00 f w fa04 top
Locate the string (e.g., EC 5C 98 BF 84 CC for Samsung TLC). Document the Controller Part Number and Flash ID. Step 2: Download the Target MPTool
The program should now list your drive in one of the slots. Click Start (or F5 ) to begin the flashing process.
Often reported by diagnostic tools, indicating the controller part number is unknown or corrupted (often actually an AU6989SN-TA or similar).
It doesn't roll off the tongue. It isn't in the manual. If you try to Google it, you might only find a handful of confused users asking, "What is this?" and "Why is my CPU usage spiking?" Alcor Controller Chip +-------------------+ | | | |
To bring the drive back to life, you need an . This software "re-flashes" the controller to its factory state.
This specific combination indicates that your operating system or mass production tool recognizes the microcontroller family, but cannot identify the precise controller revision or read the Flash ID (FID) of the memory chip.
If a 16GB drive suddenly shows as 4GB after repair, you likely had a "Frankenflash"—a fake-capacity drive that has been restored to its true, smaller size.
Always use a USB 2.0 port on the back of your PC motherboard. Front-panel ports or USB 3.0 ports often cause communication failures during low-level formatting. When AlcorMP displays , it means the software
controller fails to communicate with the flash memory chip, often due to a corrupted firmware or a physical connection issue. Understanding the "Unknown [FA00]" Error
If you are seeing this string, your USB drive is likely malfunctioning (showing "No Media" or "0 bytes"). Firmware Mismatch
When a USB stick reports this specific string, it means the computer recognizes the controller (Alcor Micro) but cannot communicate with the memory chip properly due to missing or corrupted firmware. Alcor Micro Controller Part-Number: Unknown [FA00] Firmware (F/W): FA04
