Direct answer to the question
- Your flash drive is in the controller’s ISP/boot (recovery) mode: VID=FFFF, PID=1201 and the generic strings “Manufacturer: NAND / Product: USB2DISK” are typical when FirstChip firmware cannot load.
- Controller: FirstChip “chipYB2019” (likely the same family as FC11xx; the “YB2019” tag is often a build/series code).
- NAND: Micron MT29F64G08CBCGB, 64 Gbit MLC, single CE/single channel. True physical capacity ≈ 8 GB (not 16 GB).
- Remedy: Reprogram (low‑level format) the controller with a FirstChip Mass‑Production Tool (FC MPTool) using a Flash database/profile that explicitly matches your NAND ID 2C 84 44 32 AA 04.
- Data warning: All data on the stick will be irretrievably erased by the repair.
Detailed problem analysis
- Symptoms and root cause
- VID/PID = FFFF:1201 and “USB2DISK” indicate the FirstChip controller enumerated in its internal ROM/ISP state because operational firmware or flash translation layer (FTL) parameters could not be read from NAND/OTP. Common triggers are corrupted firmware tables, invalid capacity configuration, or a badly worn NAND map.
- The tool string shows “1CE/Single Channel [MLC‑16K]” for Flash ID 2C 84 44 32 AA 04 (Micron). This Micron part number is a 64‑Gbit (gigabit) device; 64 Gbit / 8 = 8 GB. Any 16 GB report is a misconfiguration or a prior “fake capacity” setup. Your target capacity after repair should be 8 GB.
- How FirstChip USB sticks boot
- On power‑up the MCU’s mask ROM enumerates with a fallback VID/PID and waits for a loader if the external NAND tables are unreadable. With a proper MPTool and FlashDB entry, the host pushes a RAM loader, interrogates the NAND (ID, timing, geometry), builds an FTL map, scans and excludes bad blocks, and then writes controller parameters so the device can later enumerate with a normal VID/PID and present a valid LUN.
- Controller identification nuance
- “chipYB2019” is commonly seen in ChipGenius/FDIE readouts as a controller family/firmware branch, not the exact silicon marking. If possible, open the casing and read the top‑mark (often FC1178/FC1179 or similar). A precise marking improves your chance of picking the right MPTool build and FlashDB line.
Current information and trends
- Community practice (2023–2025) for FirstChip recovery relies on FC MPTool builds redistributed by repair communities together with FlashDB/param packs. Success depends far more on a NAND‑matching FlashDB entry than on the exact MPTool minor version.
- Many low‑cost “USB2DISK” drives ship (or are resold) with overstated capacities; repair generally restores truthful capacity aligned to the actual NAND density.
- Security hygiene has become important: MPTools are frequently flagged by AV; professionals now run them in disposable VMs or sacrificial Windows installs to mitigate malware risk.
Supporting explanations and details
- Why FlashDB matching matters
- The FlashDB entry encodes NAND geometry (page, block, planes, CE count), ONFI timing sets, read‑retry schemes, ECC strength, and bad‑block handling. A mismatch can lead to “FlashID not found,” “Erase/Program fail,” silent corruption, or unstable capacity.
- Geometry/ECC (typical for this Micron class)
- Density: 64 Gbit MLC; CE=1; single channel.
- Page and spare sizes vary by revision; the MPTool/FlashDB should auto‑select. Avoid forcing page/ECC values unless the tool vendor notes instruct you.
- Capacity configuration
- Set capacity to approximately 8 GB. Do not force 16 GB; doing so yields a drive that “looks” larger but corrupts data beyond 8 GB.
Ethical and legal aspects
- Firmware/MPTools for FirstChip are proprietary OEM utilities; public copies are unofficial. Use them only to repair hardware you own.
- Many public archives bundle unsigned executables; verify hashes and contain them in a VM to avoid infecting your system.
- Do not clone another vendor’s VID/PID/strings; use generic IDs or your own branding to avoid misrepresentation.
Practical guidelines
- Confirm hardware
- Optional but recommended: open the enclosure and read the controller’s top mark. Photograph the PCB (both sides). Confirm the NAND marking “MT29F64G08CBCGB”.
- Collect identifiers
- Record: VID/PID (FFFF:1201), Flash ID (2C 84 44 32 AA 04), CE=1, Single Channel, reported current 100 mA.
- Obtain tools safely
- Use a clean Windows 7/10 system or a VM. Expect AV false positives; isolate the environment.
- Acquire a FirstChip MPTool release known to support the FC11xx/chipYB2019 family together with a FlashDB that includes your Micron ID. The FlashDB is the critical piece.
- Run procedure (typical)
- Start MPTool as Administrator.
- Connect the device directly to a rear USB 2.0 port (avoid hubs/front panels).
- Enter Settings/Advanced (passwords are often blank or simple defaults; try blank, 1234, 12345 if prompted).
- Verify the tool detects your Flash ID. If it shows a close but not exact Micron ID, pick the exact line for MT29F64G08CBCGB; if absent, you likely have the wrong FlashDB.
- Set output capacity to ~8 GB; leave ECC/timing on Auto from the FlashDB.
- Enable full scan / low‑level format so the tool performs a deep bad‑block scan.
- Start (often F9). Expect several minutes to tens of minutes. Do not disconnect.
- On PASS, unplug/replug; Windows should enumerate with a normal VID/PID and capacity ≈ 7.2–7.6 GiB.
- Verify stability
- Run a full‑span integrity test (H2testw on Windows or F3write/F3read on Linux/macOS). Only accept the drive if it passes a complete write/read verify.
- If errors occur
- “FlashID not found”: wrong MPTool or FlashDB—try another build/DB.
- “Too many bad blocks” or repeated program/erase fails: NAND is worn/damaged; further attempts may succeed only with reduced capacity, or not at all.
- No detection even in ISP mode: try another PC/port/cable; if still no go, the controller may be dead.
Possible disclaimers or additional notes
- Data recovery vs. repair: If you need data back, do not run MPTools. Seek a NAND‑level recovery lab (chip‑off or in‑circuit read) before any low‑level format, since MPTools will irreversibly overwrite translation tables.
- Success is not guaranteed. Low‑cost controllers may fail permanently, and some firmware/FlashDB combinations are OEM‑specific and not publicly available.
Suggestions for further research
- Search terms: “FirstChip MPTool YB2019”, “FlashDB 2C844432AA04”, “MT29F64G08CBCGB FirstChip”, “VID FFFF PID 1201 FirstChip”.
- Communities: USB flash repair forums and databases that catalog controller/FlashDB matches for FirstChip devices.
- If you can photograph the PCB and post the exact controller marking and any test‑pad labels, experts can often point you to a matching MPTool/FlashDB set more quickly.
Brief summary
- Your stick is in FirstChip recovery mode. The NAND is a single‑die Micron 64‑Gbit MLC, so the real capacity is about 8 GB. To fix, you must run a FirstChip MPTool with a FlashDB entry that exactly matches Flash ID 2C 84 44 32 AA 04, perform a full low‑level format, and then verify with H2testw/F3. If suitable FlashDB files cannot be sourced or if the NAND is worn out, recovery may be impractical. If you need data recovery, stop now and consult a professional.
If you want, I can help you shortlist MPTool/FlashDB candidates—please share a clear photo of the controller’s top marking and, if possible, the full ChipGenius/FDIE report.
