When a USB flash drive stops working, shows a "Write Protected" error, or reports "0 Bytes" of available space, the issue is rarely hardware destruction. Instead, it is usually a corruption of the drive's firmware. Devices powered by —specifically the highly popular AU6989SN-GTC and AU6998SN chipsets—frequently encounter these software locks.
Once the program confirms completion, close the AlcorMP processing panel entirely. Wait five seconds, then physically disconnect the USB drive from the port. Reinsert the drive back into the computer. The operating system will recognize the device as a brand-new, healthy storage disk. Troubleshooting Common Errors
