    I've got a FW400 daisy chained to a FW800 drive that connects directly to my MBP FW800 port. This worked just fine for about 2 months and now suddenly the FW800 drive no longer shows up in finder or disk utility. I've reset the PRAM and turned off all drives for 5 mins, shut down all the drives, etc. I'm not sure what else I can do to get this drive to show back up. The only other thing that I can think of to be the problem is the controller in the ext. case - but I've tried plugging into both FW800 ports on the external drive. The kicker is that the FW400 works like a charm. Unfortunately, Apple doesn't have eSata option available and just the one FW800 port.

    Any ideas? Anyone seen this before? :confused:

    This happened to my WD 1TB hard drive, but its USB. The drive wouldn't mount at all, nor could it be seen it seen in Disk Utility.
    To fix it, I downloaded Disk Warrior (paid application) and it was able to recognise it and 'fix it' to a point that I could retrieve all my data then erase it. That did the trick. I've had no problems with it since (although it is quite loud - not sure if that's directly related to the incident. Ah well, it works.)
    I'm not sure there are free versions of this kind of software, but I'm sure a simple Google search will sort you out.
    Good Luck! :)

    Solution found!!

    I did a "verify disk permissions" to my drive while disconnected to all drives. I then reconnected when done and my FW800 drive is now working fine.:)
