Alcor Micro Unknown Fa00 F W 3613 Updated

Why? Because the is a relatively late firmware revision for this chip family. Most public drivers available on the internet (versions 1.0.6.0, 1.0.19.0, etc.) were written for older firmware like 3510 or 3520. When Windows queries the chip and receives "FA00 F/W 3613," the older driver's INF file does not contain a matching hardware ID. Hence, "Unknown Device."

The firmware often triggers write protection—particularly on SanDisk-based configurations with FW 3613—where the drive becomes readable but unwritable. This protection mechanism can sometimes be bypassed through appropriate AlcorMP reconfiguration.

The "FA00 F/W 3613" is the firmware version. There is no publicly available "updated" firmware file for the 3613 revision circulating on legitimate sites. The firmware is stored on a small SPI flash inside the Alcor chip (or masked onto the die). Tools like AlcorMP (for USB flash drives) or AU637X MPTool (for card readers) exist, but they are:

If the device shows a "Bad Block" error (e.g., code 30400 or 30700), go to and select Low-Level Format with Capacity Optimize .

Fixing an Alcor Micro drive with an unknown status requires low-level Mass Production Tools (MPTools). Ordinary Windows formatting tools cannot fix a corrupted controller. Step 1: Diagnose the Exact Hardware Profile AU6989SN Controller Chip Pins +-------------------+ | 1 2
