Almost all repair tools for the FA00/3613 error will permanently delete all data on the device.
The suffix F/W 3613 refers to the Firmware Version running on the controller. The firmware is the low-level software that manages the wear leveling, error correction, and logical-to-physical address mapping of the NAND flash memory. Version 3613 is a specific build configuration used by Alcor Micro for this particular controller steppings. It is part of a lineage of firmware numbers (others observed include 3613 , 368D , F0FB , F004 ), and understanding this version number is crucial for selecting the correct restoration tools later in the repair process.

Mass production tools require low-level USB drivers ( mpszfilt.sys ) that often fail or cause system stability issues on newer Windows 11 builds.
The string is a testament to the complexity hidden inside cheap USB drives. It serves as a reminder that not all storage is created equal. alcor micro unknown fa00 - f w 3613
: The F/W 3613 designation refers to a specific version of the internal firmware. If the controller reports "Unknown [FA00]" alongside this version, it often indicates the controller is alive but the Flash ID (FID) —the unique code identifying the memory chip—is missing or unreadable.
: The physical memory chips inside have a limited lifespan. Once they fail, the Alcor controller cannot load its operating instructions, leading to the "Unknown" status. Counterfeit Hardware Almost all repair tools for the FA00/3613 error
