On a whim I decided to hook up an external FireWire drive to the new Mac, then daisy-chain the old Mac to that drive. Presto! It worked, and it seemed to be just as fast as a direct connection.

A workaround for a Firewire Target Disk Mode issue
Aug 16, '07 07:30:00AM • Contributed by: blubbernaut
While trying to transfer loads of stuff from an old Mac to a new one via FireWire Target Disk Mode, for some reason the target Mac just would not mount on the desktop of the new Mac. I tried everything: different cables, different ports. I checked other computers -- they worked correctly. I even tried mounting the new Mac on the Old one -- that worked, too. But using the FireWire cable, the old Mac would not even show up in Disk Utility or Terminal.

A workaround for a Firewire Target Disk Mode issue
be careful when plugging in other devices when using TDM. I guess daisy chaining works but if you have other devices plugged in (either FW or USB) to a computer that has a mac connected to it in TDM then anything copied off the TDM mac can get corrupted. I found that out the hard way.
http://docs.info.apple.com/article.html?artnum=58583 "Important: Unplug all other FireWire devices from both computers prior to using FireWire target disk mode. Do not plug in any FireWire devices until after you have disconnected the two computers from each other, or have stopped using target disk mode." it doesn't mention corruption or USB, but thats what happens.

I don't know how old the 'older' mac was, but did you try 'hot-plugging' the old mac

I was unaware of Apple's warning, but I've never had a problem.

If the old Mac was running OS 9.0.x, it has to be updated to 9.1 or 9.2 in order for TDM to interface with 10.4. A couple months ago I tried this with an old iMac G3 and got nothing, until I updated OS 9 on it, then it worked fine.

Just a quick update in case anyone stumbles across this while searching.

This hint worked in my case. I encountered exactly the same problem in my new iMac (2007). It worked with this daisy chain fix... Weird....
A workaround for a Firewire Target Disk Mode issue
Thanks for posting this work-around. I just experienced the same problem on an eMac. I put the eMac into Target Disk Mode and its HD would not mount on a new Intel iMac. I tested cables, ports, other computers, etc. Nothing worked. The tests pointed towards some odd glitch in the eMac. So, I followed the suggested work-around and connected an external firewire drive to the iMac via FWire 800. Then I connected the emac to the external drive via FWire 400. Suddenly the eMac's hard drive mounted. I'm currently using Migration Assistant to copy the data off of the eMac.
