That error code indicates that the M: drive that you are trying to write to is a Removable drive of some type and is in the process of being removed, but has not completely been removed (otherwise you would get an error that the location does not exist).

You should not be running Sierra Chart from removable media, or even have your data stored to that location, as they are too slow and items like the above can occur.

If this is not removable media, then you need to reboot your computer, and look into why you would get that error with that particular drive.
For the most reliable, advanced, and zero cost futures order routing, use the Teton service:
