    After upgrading my 2010 Mac Mini to Lion, I started having performance issues with my FW800 connected drives. Serious lag and beach ball issues, none of which existed on 10.6.x. Now, after applying 10.7.1, I can't even boot the Mac with the FW800 drives connected... you can imagine how long it took to figure that out after updating. ARGH!

    I'm forced to use USB. Anyone else seeing issues with Firewire?

    BTW, my enclosure uses and Oxford Semiconductor chip.

    I have five on my MBP's single FW800 port - all seems well after update. Two are Rosewill (Oxford, iirc), 2 others (I forget brands, but also home built - bare drive + case), and a Seagate Desktop Mac (the white model). Four are 1TB, one 750MB. Early 2009 17" UB. I have several boot partitions among them, but haven't tried starting up on them. No problems at all booting on internal.

    I would suggest resetting the PRAM, then SMC, and see if that helps.

    Thanks for sharing your situation... I'm perplexed as I have reset PRAM and SMC several times to no avail. I'm going to try one disk than the other and maybe a different FW enclosure to try and isolate the problem.

    Meanwhile, if anyone else has Firewire issues, or success, please share. :)

    I have 2 firewire enclosures, one is the vantec drive dock FW800 version on a MBP (3,1) 15" the other is a LaCie sold as a bare empty enclosure on the latest 17". Both have WD 7200RPM 2TB drives in them and both work.

    The power management on the LaCie is a bit wonky but it has been identically wonkey under snow leopard (when it powers down it does not want to come back up, but only happens once a week or so) the other one is perfect.

    Both machines are on 10.7.1

    Three 1TB LaCie firewire drives on my 2010 mini, and 10.7.1.
    I boot off on of the drives, and have had no issues with any of them.
    Attaching a 1TB iomega drive to the chain does make waking from sleep unreliable, but I've always had trouble with that drive.
    Booting off a Unitek USB/SATA drive dock has also been reliable.

    No problem

    I haven't had any problem yet. I have a:
    - WD portable 500 Gbytes. FW-800.
    - Mercury Elite-AL Pro mini 1TByte fw-800.

    Both take power from computer.

    Have you called Apple about this issue that you are having?
