Because MyDiskTest is an older utility, it is often hosted on third-party driver sites. Always run a virus scan (like Malwarebytes or Windows Defender) on the file before opening it.
：模拟长时间或高强度的读写操作，用于评估存储介质的持续稳定性和寿命预期，尤其适用于判断是否为拆机片或残次品颗粒。 Mydisktest V2.42
While MyDiskTest V2.42 remains an effective tool, several modern alternatives offer cross-platform support and updated testing algorithms.
: It can pinpoint low-quality, discarded factory chips ("black chips") that are highly prone to sudden failure.
：检测NAND闪存芯片中的坏块数量。坏块的存在可能导致存储的文件出现数据冗余或损坏，该功能可以帮助用户判断闪存芯片的质量等级（如是否为"黑片"）。
: It scans the hardware layer to determine if the storage capacity reported by the firmware matches the actual physical NAND flash memory blocks. mydisktest --resume /path/to/checkpoint
The primary function of MyDiskTest V2.42 is to identify "ghost" sectors. When a user copies data to a counterfeit drive, the initial files appear to save correctly. Once the true physical limit is reached, the drive begins overwriting previous data or simply discarding new bits while pretending the operation was successful. MyDiskTest addresses this by performing a rigorous read-write test across the entire advertised capacity. If the software finds that data written to specific sectors cannot be accurately retrieved, it flags the drive as a fake. Technical Precision and Versatility
