You cannot use a standard Windows format tool for an FA00 error. You need the Alcor Micro Production Tool.
Alcor Micro is a massive manufacturer of USB bridge controllers. Their chips are found in everything from high-end Transcend drives to unbranded "freebie" sticks. alcor micro unknown fa00 - f w 3613
This is the firmware version currently flashed onto the controller. If this is appearing as "Unknown," it means the firmware is corrupted or the software version you are using is too old to recognize it. Step 1: Identify Your Exact Chipset
Before downloading tools, you must confirm the hardware details. Using a generic formatter can permanently "brick" the drive. Download a tool called or Flash Drive Information Extractor
This is the controller ID. It tells the software which instruction set to use.
To fix this, you generally need to perform a "low-level format" using the specific Alcor Micro Production Tool (MPTool) designed for this chipset. Understanding the Hardware You need the Alcor Micro Production Tool
The NAND flash chip is wearing out. You can try setting the "Scan Level" to a deeper cycle in the AlcorMP settings to "wall off" the dead sectors.
The "Alcor Micro Unknown FA00 - F/W 3613" error is a common headache for users dealing with corrupted USB flash drives, generic thumb drives, and SD card controllers.
