Artificial Intelligence Response

Direct answer to the question

• Use AlcorMP (Alcor Mass-Production Tool) – the only utility capable of rewriting the firmware and performing a low-level re-initialisation of an Alcor Micro controller (VID = 058F / PID = 6387, code FA00, FW F103).
• First identify the exact controller family with ChipGenius or Flash Drive Information Extractor; then download a recent AlcorMP release that explicitly lists FA00 / AU6989 support (e.g. AlcorMP 16.03.25.MD, 15.09.15.MD, or newer).

Key points
• Ordinary format/chkdsk tools cannot fix firmware corruption.
• Wrong MP-tool or wrong settings can brick the drive; follow the procedure precisely.
• All data will be destroyed – back up first if the stick is still readable.

Detailed problem analysis

1. Symptoms
   – Generic VID/PID string and controller code “[FA00]” indicate the MCU dropped into boot/ROM mode after a firmware fault, a classic Alcor failure.
   – File-system repair utilities only touch the logical partition table; here the NAND translation layer itself is corrupted, hence a mass-production (MP) re-flash is mandatory.

2. Hardware decoding

   VID 058F = Alcor Micro
   PID 6387 = Generic Flash Disk (boot mode)
   Controller family code = FA00
   Firmware reported = F103

   Probable silicon: AU6989SN-GT or close derivative; all are serviced by AlcorMP “FA00” builds.

3. Why AlcorMP is mandatory
   The tool accesses the controller’s boot ROM via vendor-specific USB commands, re-creates:
   • internal bad-block map
   • Flash Translation Layer (FTL) tables
   • User capacity & over-provisioning
   • Optional secure / CD-ROM partitions
   – No standard OS API exposes these regions, therefore Windows, Linux or macOS format commands are useless in this scenario.

4. Typical AlcorMP workflow
   a) Controller detect → NAND ID read → die count & bus width auto-learn
   b) Low-level scan (erase / write / verify every block)
   c) Create logical address map, mark weak blocks, write fresh firmware
   d) Expose a single FAT32 partition to the host OS.

Current information and trends

• 2023-2024 AlcorMP builds (19.xx.xx.MD series) add Windows 10/11 driver signing and improved TLC/QLC NAND tables; they still recognise FA00 devices.
• Increasing share of counterfeit USB sticks shipped with deliberately modified firmware; MP tools are now used not only for repair but also for forensic validation of the true NAND size.
• Industry is shifting toward UASP (USB-Attached SCSI) and NVMe-based USB SSDs, but legacy MP utilities remain essential for thumb-drive servicing.

Supporting explanations and details

Example settings for FA00 in AlcorMP "Setup (S)":

Tab	Parameter	Recommended value
Flash Type	AutoDetect (leave default)	—
Scan/Format Mode	Low Level Format → Capacity Optimise	full scan (slow)
Partition Setting	1 partition, FAT32, full capacity	—
VID/PID	058F / 6387	original
Strings	Manufacturer = Generic, Product = Flash Disk	optional

Password prompt: usually blank; if required try ALCOR, 123, or 320.

Progress colouring:
Green = pass, Red = fail + error code (e.g. 0x3050 TooManyBadBlocks).

Ethical and legal aspects

• MP tools are internal factory utilities distributed informally; legal status varies. Use strictly on hardware you own and accept that warranty may be void.
• Firmware binaries may be proprietary; redistributing them can infringe copyright.
• Always scan downloads (many archives originate from Chinese forums and can contain malware).

Practical guidelines

1. Preparation
   – Use a direct USB 2.0 port on a desktop (no hub).
   – Disable antivirus just for the flashing session to avoid interference.
   – Prefer Windows 7/10 32-bit for best driver compatibility (or run a VM with USB pass-through).

2. Step-by-step

   1. Identify controller with ChipGenius.
   2. Download matching AlcorMP build (see usbdev.ru or dl.mydigit.net).
   3. Extract, run AlcorMP.exe as Administrator.
   4. Enter Setup, choose Low-Level Format → Capacity Optimise.
   5. Press Start, wait until OK (can take 5–60 min).
   6. Safely eject, reinsert; Windows should present a healthy 32 GB volume.

3. Troubleshooting
   – Not detected: try another AlcorMP version or another USB port.
   – Error 40100/Flash ID mismatch: wrong MP build, download a newer/older one.
   – Capacity shows 8 GB: fake NAND or mismatched die list; rerun with correct flash table, else NAND is defective.

Possible disclaimers or additional notes

• Drives exhibiting >4 % bad blocks after LLF will soon fail again – consider replacement.
• If NAND is worn-out or cracked, no software fix is possible.
• Some FA00 sticks were sold as fake 32 GB while physically containing 8 GB; after honest re-initialisation they will reveal the true smaller size – this is not a tool fault.

Suggestions for further research

• Examine SMART-like statistics AlcorMP can export (PE-cycles, ECC counts) for remaining endurance.
• Study open-source FTL projects to understand translation layers (e.g., OpenNFM).
• Evaluate newer controllers (e.g., Phison U17, Silicon Motion SM3282) that expose public MP utilities with better documentation.

Brief summary

Your 32 GB USB stick is stuck in boot mode; only a factory mass-production utility can rebuild its firmware layer.

1. Detect controller with ChipGenius → confirms FA00.
2. Download a FA00-compatible AlcorMP release (16.03.25.MD or similar).
3. Run a full Low-Level Format in Capacity-Optimise mode.
4. On success the drive re-appears as a normal 32 GB FAT32 device; on persistent failure the NAND is physically damaged and the drive is beyond economic repair.
