Board disconnects when copying bin files in

As the description says, I'm having problems with the board in which the board will disconnect momentarily then reconnect every time I copy bin files into the mbed drive. It doesn't happen with the OpenSDA method but it does after I put the s19 files into bootloader. Any help would be appreciated, thanks!

Does the program you copied work? If so i don't see a problem. If it doesn't you might need to restart Windows without unplugging the USB. I don't know what OS you are using, but i was getting SWD ERROR on my Windows 10 until i did that. It still disconnects, but at least it works now. Much like any computer it likely needs to reboot to load the program, so i doubt you can "fix" that.

I have the same issue. I can't even load a sample code from this site because it disconnects the moment i try to paste something. Also, the disconnection/connection happens at random times every few seconds as well.

Also,I want the original demo code to run upon startup. How do I do that?

In windows 10, I solved this problem by stopping the StorSvc service from the task manager.
