Use a (preferably Windows 7 or 10, run as Administrator). Most MPTools do not run natively on macOS or Linux. Run the tool and locate the (e
Manufacturers purchase low-cost NAND flash chips (often factory rejects or low-grade chips) and pair them with cheap controllers like MXTronics. They then "spoof" the firmware to report a larger capacity than the chip actually has. When the user writes data beyond the true capacity, corruption occurs.
| Reported Capacity | Real Capacity | User Experience | |------------------|---------------|------------------| | 64 GB | 4 GB | Works until you write more than 4 GB, then files become corrupted or disappear. | | 128 GB | 8 GB | The drive appears to work, but writes beyond the real capacity either fail or overwrite older data. | | 32 GB | 2 GB | Formatting “works”, but the drive quickly fills up and performance drops dramatically. |
