When you try to boot from drive1 you said that you get all sorts of fsck errors, but what are the errors? Which drive(s) is/are fsck complaining about? My gut reaction is that when you boot from drive1 fstab is gettting confused about which disk is which, but there is no way to be sure about that without some more info.... I think if you sent along a copy of dmesg from a boot off drive0 and drive1 and a copy of /etc/fstab that would be a step in the right direction. There may be someone here who knows exactly what your problem is; if they pipe in, I defer to their superior knowledge.
