Note: Some mini PCs may have weaker USB signal output, which can cause random interruptions during file read/write operations during data transmission.
When this occurs, it is recommended to:
1) use the rear USB ports of the computer, as they typically provide a more stable signal;
2) test the device on another known-good computer to rule out hardware issues on the original PC;
3) use a 10Gbps USB-A/USB-C hub or splitter with a short 0.3m-0.5m cable to reduce signal loss.
