Recover Data from a Mac without Target Disk Mode
I was recently trying to pull data off of an iMac for a friend, but didn't have any Macs around with FireWire ports to get at the iMac HD in target disk mode1. This method does require an external hard drive.
Check the filesystem /sbin/fsck -y Mount the root volume mount -uw / Create mount destination mkdir /Volumes/backup Get a list of available drives df -h Plug in USB backup drive, look for new drive name df -h Mount the drive with the name you got from last step. Probably looks something like /dev/rdisk2s2. Note the rdisk / disk name difference. mount -t hfs /dev/disk2s2 /Volumes/backup rsync data to your backup rsync -ahz /Users/you/ /Volumes/backup/
