Drive size limits for target disk mode on older Macs

[jhmaughan]

I have a 2006 MacPro (Snow Leopard) that has a 3TB drive in it. All the drives are accessible over the network from other machines but when I put it into target disk mode to transfer some data to a cylinder MacPro (FW800 to Thunderbolt adapter) only the smaller drives showed up (250 & 750GB) and not the 3TB. Is that a limitation of TDM on older machines?

No idea about the TDM limitation , but you might consider setting up a PAN with gigabit Ethernet for transferring files . It'd be a lot faster than FW800 anyways . Theoretically , 125 MB/s transfer speed .
