Hold the "T" key down on the keyboard of a mac during boot, and instead of loading the operating system it'll load a simple firmware that exports any attached hard drive(s) over the Mac's FireWire ports, making the Mac behave like a FireWire external hard drive. Unfortunately it's useless with most machines as it appears to require a USB gadget or OTG port, or a FireWire port.
This will make it much easier to produce bootable USB keys that export the host system's hard drives. UPDATE July 2012: Kernel Newbies reports that support for exporting SCSI over USB and FireWire has been merged into the Linux kernel. Unless you have an Apple you don't get it, and there's no longer any good reason for that. Target disk mode is great for data recovery, OS repairs, OS reinstalls, disk imaging, backups, accessing data on laptops with broken displays without having to rip the HDD out of them, and lots else. This is a tech support and service dream, and has been supported since Apple moved over to "New World" PowerPC machines with their Forth based OpenFirmware, ie for a very long time. If you do have to remove the entry from the registry, BACK IT UP FIRST.I'm not an Apple fan, but there's one thing that consistently makes me really jealous about their hardware.ĭespite generally scary-buggy EFI firmwares in their Intel CPU based machines, Apple's firmwares support what they call Target Disk Mode. The first fix (uninstalling and reinstalling 1394 host controller) worked for me, and I was able to transfer the files.Ī word of caution however, unless you have a OS install disk readily at hand I would not run the risk of removing anything from the device manager. Disable the 1394 connection in "Network Connections", restart, thenm re-enable the connection.
If the drive is not listed anywhere in the device manager there may be a problem with the FireWire port on the computer. At this point follow the instructions at the bottom of the page Here.ģ. If it is and you still do not have the drive mounted in your "My Computer" location, open the device manager and look for an "UNKNOWN VENDOR AND MODEL IEEE 1394 SPB2 DEVICE." If this is there the computer is at least seeing the Mac's HDD as an external drive. Verify that the 1394 connection in enabled in the Network Connections control panel. Here are is a list of things you should try, assuming you have XP.ġ. I opened "My Computer" and my HDD from my PB was "F \" Later when I was trying to transfer files I plugged it back in and it did not show up. The first time i tried it, it just worked.
