Hello everybody!

I have a sporadic problem with my user accounts on my snow leopard machine:

from time to time all user accounts get deleted. I am able to restore them by logging in as root and simply re-adding these accounts with their respecting parameters. After this, all data is there again, so i would say it is no hardware failure.

I would like to attach a corresponding console output but it is very long. Is there another way to share it with you?

thx in advance!

    Im getting the same thing.
    We had 200 Macs all running snow leopard. One Mac done the same thing this evening.
    the local Admin and workstation account were deleted. It did not effect root.
    We have network accounts via OD for the majority of users, but some require local accounts for Final Cut Pro access for other students. Here is my log, any help very much appreciated:

    I've had the same problem this morning. Before leaving for class, I've accidentally rebooted instead shutting down my MBP. While on login screen, I've unplugged all the peripheries, including external HDD. I noticed, that the login screen changed from my name to Other...

    I could not log in anymore, so I rebooted into single-user mode and found out that my account is marked as deleted. After "restoring" the account using root, i was able to log in normally, so I checked console, and I found a lot of entries with xaDiskDisappeared. One of them was also my account.

    I think Apple should fix this ASAP, since my account was not external, and my external HDD contains only TimeMachine backup (just user files) and some data.

    Console log is here: http://cl.ly/1m2z2y42132Q2O3z2M2T

    So this is a Mac OS X bug? Same with me, no external accounts, just a External HDD with TimeMachine backups on it. Could it be that this came with the latest update (10.6.5)? I never had a problem with 10.6.4.

    Yeah, it is possible...I don't want to reproduce it again - it was quite a PITA to fix it from single-user mode:)

    What did you do before the accounts have disappeared?

    Not quite sure, i just remember that there was a problem with a unmounted external device after restart (there is something in the console log). Another thread refers to our problem, seems to be an issue with Mac OS account manager, mixing up external and non-external accounts. As mentioned in this post (http://discussions.apple.com/message.jspa?messageID=12731083#12731083) disabling external accounts could be a workaround until apple releases a patch.

    Hi there,


    2+ weeks ago, I had the same problem at work on my MacPro.

    After restarting, system log told me trying to delete every accounts on my mac.

    Here an extract of the log :

    Feb 4 18:34:53 MacPro ManagedClient[107]: -xaDiskDisappeared error attempting
    to delete empty home account '_coreaudiod'. localUserMCXRecords count = 53

    I dont have any MCX, i use local account on the principal HD.
    Only my account was delete, not my homefolder. Phew !

    I have had the same problem, the additional issue I am having is that I am currently in Afghanistan and I have no way of contacting Tech Support.  Can someone tell me please how to re-add my Admin account as a user through the root drive?

     

    Thank you, Dan

    Hi Dan,

     

    The solution you have is to boot on single user mode, mount your hard-drive as written on the terminal, then delete the file /var/db/.AppleSetupDone

     

    This will launch Setup Assistant on the next restart, that permits you to create the first admin account
