It can not be formatted on any windows or mac computer or on any other digital mediaplayers device and settop box.

The current data files on it can be read/copy with no problems.

No.  It is a electrical problem not a software problem.

“can someone explain why this happens, what action makes the usb drive to goto selfprotect mode by itself technically?”

Power surge and/or heat are the most likely suspects.

I hope that this is still under warranty and I would suggest for you to check if you can go ahead and ask for a replacement to this.
