Well, while the master is working fine (it correctly detects a currupt 
mailbox), it seems as though the drive is not acting correctly. 

Contact the drive manufacturor. It is not unusual that the manufacturor says 
"but it works with TwinCAT", wheras there are still are protocol 
implementation errors.
