I had a pretty miserable experience lately and I wanted to share the simple lesson I learned. I have an external FW/USB2 drive case into which I swap a few ATA drives. It was unplugged for a while and when I plugged it back in, I used the FW cable which came with my 1G iPod. The long white one. Anyway, All the drives I plugged into the case appeared unmountable, or unreadable, or unverifiable/repairable (Disk Utility), or unrecoverable (Data Rescue), or unfixable (DiskWarrior). I was not happy. Long story short, I replaced the cable with another one and everything returned to normal. It was such a huge relief. So, kids, when you experience krazy external drive behavior, don't rule out the cable (even a cable which seems to work normally, say, tranferring songs to a 1G iPod.)
