Cannot enter external firewire drive

There are four entries in the drive directory for the one drive. The drive has a Mac and a Linux partition on it. I get this error: Could not enter folder /media/ieee1394_sbp2-00d04b35e0022046-0-0p1 for three of the four entries (op1,op2,op3). /media/ieee1394_sbp2-00d04b35e0022046-0-0p3 is the one that I can access my Linux partition through. Before the latest online update (today) none of them would allow access to my Linux partition on this drive, now one of them will. Anyone know why there are four references to this drive and why three of them cannot be entered? Thanks, Jerome
