In the case of using Target Disk mode between computers, a similar restriction is also present. Since Thunderbolt devices have a Thunderbolt connection and controller in them, if you attach the adapter to them they will likely detect the presence of it in one way or another however, they will have no means of using it since the RAID array does not have the appropriate drivers to interface its services with FireWire. Inverting it and attempting the connection in the opposite direction will not work. The Thunderbolt adapter is a unidirectional bridge from Thunderbolt to FireWire that requires a computer host with software drivers to interface with the controller it contains. While these ideas seem reasonable and would be nice to have, unfortunately they cannot be done. to connect a Thunderbolt RAID array to my Mac Mini." Apple's Thunderbolt FireWire adapter can connect to Macs via both ends, but can only be used in one direction. Can I use the Thunderbolt/FW adapter in reverse, i.e.

I am now looking at adding a RAID storage unit. MacFixIt reader Keith writes: "My current Mac Mini server came out before Thunderbolt, so it has FW800. In addition, some people have wondered about using the adapter to allow systems with FireWire to use various Thunderbolt-based devices such as RAID arrays and even some new docking stations that are becoming available. MacFixIt reader Charles asks: "Would adapter allow a MacBook Air to connect to another computer's FireWire port in FireWire target disk mode, via the Air's Thunderbolt port?" Given that some new MacBook systems do not have FireWire, people with older systems who have purchased one of these new MacBooks might benefit from using an adapter to mount the new system's drive on the older computer. In some cases people have wondered about the options for troubleshooting systems using Apple's Target Disk mode, where the hard drive of one can be mounted as an external drive on another system through either FireWire or Thunderbolt connections.

Since the adapter links both FireWire and Thunderbolt and can be connected to from either end, several readers have been hoping to use it as a bidirectional bridge between systems with Thunderbolt and those with FireWire. This adapter offers FireWire connectivity to the latest MacBook Air and MacBook Pro with Retina Display, which do not have built-in FireWire connectivity. Recently Apple made its Thunderbolt-to-FireWire adapter available, which was announced along with Apple's latest MacBook systems at this year's WWDC.
