I am running few computers attached to Buffalo HD-CE1.0TLU2, the windows XP machines have no issues saving files to the drive but all the Window Vista PCs receive an error while saving in Word, Excel or any other application that 'the save failed due to out of disk space or memory'. I have no issues drag and dropping files in explorer using Vista machines.
I have tried to reduce the LmCompatiblityLevel to 1 and did not have any impact.
Thanks
