right now if there are errors with Expandrive, it just continues to try the last command. For instance, if permissions on an S3 bucket are incorrect, Expandrive will keep trying over and over. The calls it continues to make are being charged back to me. It is a small amount but if a user has an issue and leaves their computer on overnight, Expandrive will keep trying those calls all night and AWS will keep charging me for them. Now multiply the issue on 10000 computers and the charges will become substantial.
