Permissions broke on external HD

[Ashy90]

Ever since I re-installed Lion and used migration assistant my permissions have been goosed on my external HD (Mybook 2tb).

I don't know any terminal commands other than - ls -alOe /Volumes, that could help.

Here is the output:
total 8
drwxrwxrwt+ 5 root admin - 170 13 Jun 14:10 .
0: group:everyone deny add_file,add_subdirectory,directory_inherit,only_inherit
drwxr-xr-x 34 root wheel - 1224 13 Jun 10:06 ..
lrwxr-xr-x 1 root admin - 1 13 Jun 10:05 Ashy -> /
d---------+ 19 501 wheel - 714 4 Jun 01:26 Backup
0: group:everyone allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity
drwxrwxr-x 7 Ashy staff - 306 12 Jun 15:39 Untitled 1

I don't want to nuke my HD and start again as I have 1.7tb of data on it.

Please help.

Are you an admin on the machine? Will the hard drive mount? If so, you could try Repair Disk Permissions via Disk Utility. If that doesn't work, you could do "Get Info" on the drive and then try to modify the permissions there or even Take Ownership and make sure child objects are included if you have trouble accessing sub-folders. Taking ownership of child objects may take a while.

Of course there are Unix commands that could be used. I can look some up, but I don't know them off the top of my head.

Also i've tried to de-crypt the volume but with no success

Yes I am the Admin.
I'm sure if I just apply permissions through the GUI to all sub folders it will cause more harm than good, I think my best option is fixing it through terminal as i can't use disk utility to fix permissions.

The drive is encrypted as well?

 

[Ashy90]

Yeah

Ewww, I didn't get that at first. What was used to encrypt the drive? FileVault or some other 3rd party tool/software?

Also, how did you upgrade to Lion? Was it a clean install?

Nothing has helped, tried various methods. Permissions are just ****ed, bit pissed off really seeing as all i've done is clean install Lion an then use migration assistant.

Going to have to lose over 1TB worth of data.

Lesson learnt, DO NOT USE TIME MACHINE.
