I have a DP 2.7 PowerMac with 5 external Lacie hard-drives. I can get two of them to show up via firewire 800 (chained together), but my other 3 won't show up now, even though they showed up this morning. I moved my computer from my home (where all 5 were working this am) to my office where the additional 3 are now not showing up. I've tried everything from running each wire independently from another firewire 400 port directly to the HD, to switching the cords around, to switching the chain order and nothing is working. I have a full head of hair, but am now in the danger of going bald - HELP! Thanks in advance!
