Can not log in after upgrading to snow leopard 10.6.5???!! help!!!!!

May be of help to some...

After re-installing my system from time machine I could not access my 2TB LaCie FireWire Drive anymore. System said: "You don't have the rights to access". Drive was locked.

A little but very helpful App called "BatChmod" saved the day - it is very powerful on changing file rights. Google for it, and be careful using it.

I only know the german interface of BatChmod, but some hints:
on the button on the top left, you can not only choose files but a whole drive to change permissions
permissions can be set to "owner", group", "everyone" and a long list of other optional assigns in dropdown boxes
OPTIONS: be careful, I just ticked "Change owner and permissions" and "unlock" and it unlocked my LaCie Drive.

Best luck
Chris

VK said for locked HDs and volumes at http://discussions.apple.com/thread.jspa?threadID=2329689

sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*

This is my exact situation. Although I never use two leads. Don't have fileVault running, nothing unusual about the iMacs setup. Has happened before and I'm sure I found a way to fix it without restoring or recreating users. Somehow reconnected the user or something.

P.S. Couldn't find information posted by a "lludes"...

Oh sorry. I did a search and for some reason it didn't come up in the results. Thanks for the link.

Hi, I would like to offer this. Today I had this problem occur and with some research found easy solution, really it's much simpler than all the other ways I read. I wrote up what I did and posted it in a reply to my own call for help. Link bellow:

Sorry about the poor editing in that.

Step 5 does not work for me.

When I enter
+xar -xf dslocal-backup.xar dslocal/nodes/Default/users/username.plist+
The message i get is: "no files matched extraction criteria".
I think the problem is that there is no file username.plist . At least I do not see it in de directory dslocal/nodes/Default/users/username.plist
(Of course username is replaced by my name)

When I only enter
+xar -xf dslocal-backup.xar+
I get a lot of error messages like this:
Error whil extracting archive: (dslocal): perm: could not chmod file (red-only file system) - ignored.

I sincerely hope someone can help me.

By the way, I am on 10.6.6.

Hey MacAppie,

Before booting into Single User Mode, go to terminal and do:

+defaults read /Library/Preferences/com.apple.preferences.accounts+

Scroll up in the terminal buffer and copy and paste the entire output of the command into a textedit doc. You will then have all of the short names of your deleted users. If there are any you DON'T want to restore, you need to make a note of that and not do so, although you could always delete them later.

Then when you boot into Single User Mode and get to Step 5, you sequentially put in:

+xar -xf dslocal-backup.xar dslocal/nodes/Default/users/bjones.plist+
+xar -xf dslocal-backup.xar dslocal/nodes/Default/users/rsmith.plist+
+xar -xf dslocal-backup.xar dslocal/nodes/Default/users/andsoforth.plist+
+xar -xf dslocal-backup.xar dslocal/nodes/Default/users/fortherestofyourusers.plist+
+xar -xf dslocal-backup.xar dslocal/nodes/Default/users/yougettheidea.plist+

Once you've done a line for each of your users, then do the single command:

+xar -xf shadow-backup.xar+

Then for Step 6 there is a typo (you need ".plist" at the end):

+rm /Library/Preferences/com.apple.preferences.accounts.plist+

llude is the MAN (or WOMAN)! Upon finding my webserver local DS completely empty (short of the Unix accounts like root) this morning, I was ready to sell my 10.6.6 final-gen Xserve on eBay and buy a Dell with Server 2008 R2. Thanks to llude, Apple has kept me as a customer for a while longer! In my case, it did it out of NOWHERE. I ran a 10.6.6 update weeks ago and last night added a user to my perfectly fine local DS and came in this morning to find my local DS EMPTY. I could see in the log the xardirectory errors where it deleted all the "external" accounts. I hope this bug has been fixed in 10.6.7, although I will wait until April 21st to install 10.6.7. After the major bug in 10.4.7 (if I recall) that took two weeks to fix, I always wait a month before installing the major updates.

Thanks llude...you truly rock! You saved my Friday!
