Well, it appears that I have isolated the problem quicker than I had expected. My first choice in testing out various configurations was the simplest: to detach the LaCie drives, leaving only the Seagate/Icy Dock. When I did that and rebooted, the Seagate/Icy Dock again did _not_ show up on my Desktop nor in Disk Utility, and appeared to System Profiler as an Unknown Device. So, it looks like there's something wrong with the drive, the enclosure, or the cable. Inasmuch as I swapped the cable with one of the LaCie cables, I think I can rule that out. Beyond that, I don't know how to isolate the problem any further. -- iMac (27", 3.06 GHz Intel Core 2 Duo, 4 GB RAM, 1 TB HDD) � OS X (10.6.3)

However, upon reflection, this machine (which is brand new) apparently arrived with the Finder prefs already changed from the default settings to display the external HDs on the Desktop, inasmuch as they showed up immediately when I plugged them into the machine. >> If it was me, I would be trying several combinations of the devices and >> cables to see which configurations don't work. >> >> I'm inclined to suspect some kind of fault with one or two of the >> devices you have connected, which is causing them to conflict with each >> other. >> >> A full dump of what you see in System Profiler > Firewire for a "good" >> and "bad" configuration (with details on the order in which everything >> is connected) might provide some hints. > > > > Well, it appears that I have isolated the problem quicker than I had > expected.

I spoke to LaCie re: the problem suddenly occurring after I inserted the 2nd of the two brand-new LaCie HDs in the daisy chain. They assured me that there is no cause and effect going on -- that there is no way that the insertion of that drive could somehow have killed the Seagate/Icy Dock. But I'm having a difficult time accepting the notion that the sudden "Unknown Device" nature of the Seagate/Icy Dock and its unavailability (i.e., vanishing from both the Desktop and Disk Utility) is a complete coincidence. -- iMac (27", 3.06 GHz Intel Core 2 Duo, 4 GB RAM, 1 TB HDD) � OS X (10.6.3) |
