2nd and 3rd hard drives not detected

[pedplar]

I awas running beta 4 and everything was working fine.  did a fresh install of rc1  and my 2nd and 3rd drives doesn't get detected.  if i hook them up to my desktop they work fine.  if i start up kde on the core i am able to mount them. but linuxmce wonn't do anything with them. anyone have any ideas why
