Flash drive malfunctions that lead to a "Unknown [FA00] - F/W 3613" detection typically fall into a few categories:
: If the tool still doesn't see the drive, you may need to manually enter "Test Mode" by shorting specific pins on the controller chip (only recommended for advanced users). Change VID/PID : Sometimes changing the ID using the Alcor Change PID/VID Rework utility can help the software recognize the hardware. : Always use a USB 2.0 port alcor micro unknown fa00 f w 3613 updated
If your USB flash drive has suddenly become unrecognized, displays of space, or shows a "Write Protected" error, you are likely dealing with a corrupted controller firmware. When checking the device using a low-level diagnostic tool like ChipGenius or Flash Drive Information Extractor , it often surfaces with the specific error: Controller Part-Number: Unknown [FA00] accompanied by an internal firmware string like F/W 3613 or similar (e.g., F/W F103, FD00).
When a drive with this controller fails, it typically manifests in the following ways: Device Status
