: Bypasses software-level write-protection locks that standard Disk Management tools often fail to clear. Bad Block Management
If the block turns , the tool will display a specific error code (e.g., Bad Block Error , Too many bad blocks , or Firmware mismatch ). This indicates either physical chip degradation or that you need to try an alternative software revision version. Common MPTool Error Codes & Fixes Error Code/Issue Probable Cause Actionable Solution Tool doesn't detect USB Non-standard VID/PID parameters.

| Error Code / Message | Description | Potential Solutions | | :--- | :--- | :--- | | | A generic error often due to a bad flash or problematic controller state. | Try low-level formatting; check flash seating if possible. | | Too many bad block error (50400) | Flash has exceeded the maximum tolerable number of bad blocks (often 2048/2048 full). | Use a newer version of the MPTool; apply a stronger or different ECC (Error-Correcting Code) algorithm. | | 30500: No support flash error | The exact flash chip isn't recognized by the tool's list. | Locate a newer version with an updated flash database. | | 30400: Unknown flash error | The flash chip isn't identified, likely missing from the database. | Find the correct MPTool version; try alternative tools like FC MPTool . | | Get Device Mode Error (0300) | The controller responds but is in an unexpected or locked state. | Select a different USB port (preferably 2.0) and re-insert the drive. | | 0x80003000 (purple text) | Hynix-specific flash error requiring a special handling routine. | Tick the "Special Flash" or "Hynix80003000Error" option in settings. | | Tool buttons greyed out | Tool won't recognize the drive. | Modify VID / PID in the INI file or run the tool as an administrator. |
One of the most common issues is a flash drive that suddenly becomes "write-protected." You can read files, but you can't delete them, format the drive, or copy new data to it. For the AU6989SN-GT series, this is often not a physical switch but a logical failure that occurs in (e.g., pulling the drive out while it is writing data). A correct "low-level format" using the MPTool is the standard fix for this.
MPTool is proprietary software owned by Alcor Micro. It is often distributed without a license by third-party websites. Use it only on drives you own. Rebranding devices by changing VID/PID to counterfeit high-capacity drives is fraudulent and illegal. Common MPTool Error Codes & Fixes Error Code/Issue
Scans the NAND flash memory, isolates degraded sectors, and maps them out so the controller ignores them.
Fix: The NAND chip is physically worn out. Go back to Setup, increase the ECC capability, and change the scan level to a deeper cycle. If it still fails, the drive has reached its end of life.
The computer detects the USB hardware interface, but the disk management console displays the storage capacity as 0 MB or 0 bytes. their policies apply.
A 64GB drive suddenly shows up as an 8GB or 16MB drive due to corrupted partition tables or damaged flash geometry data.
