When I run your script, I get an error that the device is busy. I checked lsof grepped for my file but nothing comes up.

I'd like for this to work, and I'm willing to help but I'm not a coder. If there's anything that you would like for me to check on while I have it in this state, let me know. Otherwise I can think a few things to try like, reboot.
