Error Message - caller does not have execute access



I was wondering if someone else had this issue before and maybe can provide
some feedback.
I am using VS 200r R2 and a Buffalo terraStation. I would like to be able to
store the configuration and the vhd files on the TerraStation.
I created folders on the TS but when I try to start i receive this error
message :The following error occurred: The virtual machine could not be
started because the caller does not have execute access"
I know that it has something to do with permission and the fact the TS is
Linux based but I could not get it to work
