Please describe your issue in as much detail as possible:

When attempting to format a drive via Steam > Settings > Storage, the option will remain available while formatting is in progress. Attempting to do so a second time will lead to an error message and cause the spinner (indicating progress on the initial format) to revert to a MicroSD card icon.
