Hey everyone. Has anyone tried using these drives with OSX? I just received (2) of the 250 gb variety. My plan was to use both of these drives in a RAID 1 array for all of my important documents and files. I've created the RAID1 set and all appears to be well. When I try to copy several large files (3 gb total) and then try to open up another program such as Safari, the file transfer stops and then my Finder will stop responding if I try to stop the transfer. The only thing I can do it shut off the hard drives. I found the following in the Console system.log: AppleRAIDMember::synchronizeCacheCallout: failed with e00002bc on ABAD5338-8DEC-44E2-97FA-32B863668FC4 Is using both drives at once too much for the system? I have an Imac G4 USB 2.0 model. I thought maybe it was firmware, so I downloaded the latest Lacie firmware and when I launch the Updater is just closes within 5 seconds while scanning the bus for the drives. Any suggestions? Thanks!
