It's just a thought. I did the firmware check by pressing zoom 6 0 6 zoom on the remote and the firmware is displayed including HDD type. The HDD type is blank obviously but I began to wonder. Or is it just the case that the same firmware is used on the DR1 and XS30. I've only had the machine 3 weeks and don't want to invalidate the warranty by checking to see if there's an IDE interface.
