Error using mkdir, device not ready

I have been running this script many times over the last 6 months with no issues, all of a sudden i can not run it on any of my machines that ran it before due to 2 erros

One machine gets the following error "error using mkdir, device not ready"

so i try my laptop and i get "error can not use + sign"

this are new errors to me in matlab.

thanks

You appear to be using some kind of network drive. You will likely need to shut down the network drive and restart it -- typically by rebooting. If that still does not work then something is wrong on the network drive side.

this is a local drive on my windows machine. It is not mapped or on the network :) hope my drive is not going out

I would recommend running hardware tests on the drive.
