pkg) and extract the files you need to recover. Use Pacifist to open the Mac OS X Update Installer package file (which ends in. You should really both be on the latest OS, but none the less, download the Apple software update (this may have changed since writing this article, so please do a little checking around).ĭownload Pacifist and install the app. Skip this section if the two machines are the same. Step 3 and a half - Manually Getting a Copy of the System Files You will need to get these files manually (explained below). Akin to a shortcut, but it's the UNIX name (plus, they're smarter than shortcuts, but that's another conversation).Ĭaveat: The following all assumes the happy mac is the same OS as the sad mac. * A symlink is a file that points to the original file. Ingeniously named, this directory contains symlinks * to the individual files that are corrupted. The Disk Utility had created a handy directory pointing out all the corrupt files. Some system files had been sitting on the corrupted part of the disk, meaning that it still wouldn't boot up. Once the Disk Utility has done it's job, the disk might be all good to boot with. it's not connected to another machine), but repair would hang and in fact, not repair :-( Step 3 - The Manual Recovery Magic Note that from the tests we did, booting the sad machine from the Mac OS installation disks allows you to run the Disk Utility (i.e. If all has gone well, the bad sectors on your drive have been flagged, and the Disk Utility has told you that some of the disk had errors but they're repaired. It can take quite a while, so go get a coffee, make a sandwich or whatever takes your fancy. Select to 'repair' the firewire drive, and let the Disk Utility go about it's business. You should find the external firewire drive listed.ĭon't, repeat: don't, go and nuke the happy machine's drive. While the sad machine is connected to the happy machine, open Disk Utility (hiding in the Applications -> Utility folder). Depending on the severity of the problem, you may find this is only happening on a single file or two. Start the process again and avoid the area that caused the backup to hang. It'll be fine, it's likely that the bad part of the disk has been accessed and the drive can't be read. If you find that the backup crashes or hangs at any point, pull the firewire out and reboot the sad machine. Copy anything that you can't recover else where to the happy mac. The worst outcome is you can't recover the drive, and you'll need to buy a new one.īack the f*** up. Now that you've got the drive available, assume the worst. In particular, target mode (holding 't' on restart) will boot the machine up as a hard drive accessible via the firewire port.īoot the sad machine up in target mode and the other (happy) machine will see it as an external firewire drive.
