Unlike standard Windows formatting, MPTools physically restructure the NAND, setting aside bad sectors and initializing the controller firmware.
This process will completely erase all data on your USB drive. There is no undo button. Back up all important files before you begin.
The FirstChip MpTools tool has been updated several times, each version addressing specific bugs and adding support for newer flash chips. Firstchip Chipyc2019 Mptools
This utility is primarily used by technicians or advanced users to recover "bricks"—drives that are write-protected, showing "no media," or reporting 0MB capacity. It works by performing a "low-level" format that maps out bad sectors and re-flashes the controller's firmware. Preparation Steps
ChipGenius will display a list of all USB devices connected. Locate your USB drive from the list. Back up all important files before you begin
: In the architecture of FirstChip Technology Limited, the chipYC2019 hardware profile corresponds directly to the FirstChip FC1179 controller series.
If your 64GB drive turns into a 16GB drive after repair, do not panic. The tool automatically isolates corrupted, unstable sectors to make the drive safe to use again. A smaller, stable drive is always better than a larger, unusable one. Conclusion It works by performing a "low-level" format that
: If you are repairing a "fake" drive (e.g., a 2TB drive that is actually 32GB), the tool will restore it to its actual physical size . FirstChip FC1179 MpTools V1.0.7.2 (2024-02-21) - USBDev.ru
|| Likely Cause | Solution | |---|---|---| | "No Drive Detected" or Tool Doesn't See My USB |Driver conflict, poor USB connection, or the tool is not running as administrator. Try a different USB port (especially a USB 2.0 port directly on the motherboard).|Always "Run as administrator." Try a different USB port. Close and reopen the tool. If still not working, restart your PC. If the drive is completely dead, it may not appear.| | Repair Process Fails with "Error 2" or "Error 6" |Flash memory is incompatible, damaged, or the wrong Flash ID is selected. Or there is a problem with the drive's partitioning.|Re-enter settings and manually select your Flash ID from the list using ChipGenius. Switch from "Capacity" to "Quality" priority in optimization settings. Low-level "Clear + Factory" scan is the most thorough option.| | Drive Capacity Shows Only a Fraction of Expected Size (e.g., 7.5GB out of 32GB) |The tool has detected an excessive number of bad blocks and has "blocked" them. This often happens with heavily used or counterfeit drives. It is safer to use a reduced capacity than to risk data loss.|Run a "High Scan" or "Clear + Factory" scan. Select "Quality" in optimization mode to prioritize stability over capacity.| | "Please Insert Disk" Error Still Appears After Repair |The low-level formatting or partition table creation was not completed successfully. The drive may still have a RAW file system in Windows.|Re-run the tool using a "Clear + Factory" scan level, then after completion, use Windows Disk Management to create a new simple volume and format it as exFAT or NTFS.| | The Flash ID Can't Be Found in the Tool's List |Your Flash ID is newer than the tool version you are using. This is more common with highly recent counterfeit drives that use non-standard Flash IDs.|Download a newer version of MpTools (e.g., V20220601 or V20240221). Use the "Spec Flash Name" field and try an older or similar Flash ID, or set the "Flash ID" to "Auto" to let the tool guess.|
Unlike a standard Windows format command, which only clears the file allocation table, MPTools communicates directly with the Firstchip microcontroller chip. It can rewrite the chip's internal firmware, execute low-level formatting, partition the drive at a hardware level, and isolate degraded memory cells. When to Use Firstchip ChipyC2019 MPTools
Here’s a common procedure to restore a chipYC2019 drive that is showing the wrong capacity.
