I've found Windows firewire hard disk support to be flaky on some machines.
I have a Maxtor 80 gb firewire drive that all of a sudden is not recognized by Windoiws XP. I powered off and restarted and it was recognized, then the computer acted as though I had shut off the drive, which I hadn't. Most of the time I restart the drive my computer won't recognize it though the lights are on indicating the drive is getting power. Every few times my computer recognizes the drive for a second, then loses it. Same scenario when I tried the drive on another computer. Any ideas how I can at least run the drive long enough to move everything off to another drive? Any ideas would be appreciated. Thanks
