HI Alex, Thanks very much for the link and letting me in on the "Panther + Firewire = Trouble" situation (I am reading into it right now). Sure enough, my drive was totally reliable under OS 9 and now it's been hosed the way the article suggests. I'm pretty horrified that my device has been turned into a death trap for my data. I bought my drive from PowerMax and they aren't listed under the group of mfr's who are providing firmware updates, but I will check their website and/or write them an email to see if they publish the firmware upgrade. I really hope I don't have to disconnect the drive and not use it anymore. It's only a couple years old. Details about my upgrade, fyi: I disconnected ALL my peripherals from my AGP G4 when I upgraded to OS X; I read a few articles on upgrading and one of them stressed doing this. I only reconnected the external HD after I was sure that the new OS was running alright (or so I presumed), and hoped for the best. At first, it looked OK and then I began to see the "Stepford Wife"-like replacement icons for my files (just black boxes), and noticing they had zero K... Also, I upgraded using v. 10.3.5 discs supplied with the purchase of Panther I mad some months back; Apple was running a special deal: purchase both Panther + iLife '04 and receive a rebate. The first thing I did, incidentally, after upgrading to X was let the computer check for new software, which is how I am now at v. 10.3.9. Again, thanks so much for your help.
