Physically the first four drives in the top list (the two WDCs and the two Samsungs) are connected to the first controller. The two Seagates are connected to the second. > Try experimenting by changing which disk is connected to which port and see > if you can get the behaviour you want. I don't really want or nead any behaviour in particular. This is just a matter of what's in the fstab. I was more wondering how this could be and if this order (and thus the device names) will stay constant or if the OS could get funny ideas after a csup and change this again, which would certainly mess up my directory tree. I was also wondering about the "gap" there is in the device names. The first controller should get ad4,6,8 and 10. But then, the second should get 12 and not 14. What happened to 12? Regards, Chris
