Post-Flashing Verification: Ensuring a Successful Restore

After using the usbfirmwaretoolalcorau6366au6371 verified, perform these checks:

1. Capacity Check – Windows should show correct size (e.g., 8GB, 16GB). 0MB or RAW format means failed flash.
2. Write Test – Copy a large file (e.g., 1GB). Speed should be consistent (5–15 MB/s for USB 2.0).
3. Volume Serial Number – Use vol in CMD. It should not be all zeros.
4. CrystalDiskInfo – SMART data (if supported) should show low error rates.

If any test fails, rerun the tool with "Low Level Format" enabled. If still failing, the NAND flash may be physically dead.
