I did something stupid. I pulled the plug out of my LaCie 2big 6 TB thunderbolt disk. As I'm currently using a 128 GB MacBook Air 2012 (which offer too little capacity), I moved my Home folder to the external drive. This worked pretty well for months. But then I suddenly pulled the plug of the LaCie when it was running and OS X froze (everything grey). This happened before and when I rebooted with the TB drive running, everything was fine again. But not this time. For some weird reason a blank account appeared after booting, with the default settings. My home folder was at /Volumes/3 TB RAID 1/Home-map/jeroen but nothing happened. It looked like the Mac had made folders named exactly the same as my external setup: '/Volumes/3 TB RAID 1/Home-map/jeroen'. I saw the folders when selecting it to change it to the original external location. When changing it to the external, nothing happened after reboot. Still a blank default desktop without any files (the files are still on the external). Changing the location of the home map didn't seem to have any effect. I then though the Mac got my home folder mixed up somehow, so I changed 'Home-map' to 'Home_map' on my external drive. After that I changed the location of the home map and pointed to this location. (/Volumes/3 TB RAID 1/Home_map/jeroen) But then I got an error while logging in. Just 'You currently can't login on account jeroen. An error occured so logging in is not possible' (translated, so it might nog be the exact words in English) And then changed it back tyo 'Home-map' but got the same message. So, I have all my account data, settings and programs (mail and such) on my external drive, but can't login. Luckily I do have a second user account with administrator rights (which I use when I use the MBA offsite). Does anybody have a clue about what to do next? I'm now considering to copy my external home map to my second user account, including all program data - but is this possible due to rights? Is there another option to restore my account?
