External PHANTOM Drive (no access) Permission, Disk Utility, Mounted, Terminal Code

NEED HELP BAD!!!

i have a external firewire hard drive with absolutely nothing wrong with it except the fact that i set the permissions on it (through the "get info" window) to "no access". i do this with folders all the time that i don't want the average joe taking a look at. very light protection because all you have to do is get info and switch the access.

well on a drive that needs to be mounted in order to see in the first place, this trick doesn't work so well. so i take complete blame for the fowl up.

so, i have talked to a mac friend and after a bit of time got me back into the drive by clearing up permissions through the terminal and remounting the drive.

sudo chmod -R +rw /Volumes/liQuidAPOGEE
sudo chown root /Volumes/liQuidAPOGEE
sudo chgrp wheel /Volumes/liQuidAPOGEE

after this i remounted the drive through Disk Utilities, and it seemed to mount and i could look at the files inside. wow, i was stoked.

well after that i didn't need that external drive for a week or so, because it is a backup drive that has files i don't access often.

so finally, today i tried to acces the drive after purchasing a new internal HD and backing up my entire system to my second internal HD. i needed more space because my client folder just keeps growing. that's a good thing.

at the point i had a complete duplicate (using Super Duper!) i switched over to the new HD with the cloned system, fired up the external that had been giving problems last week, and it was once more invisible. it shows up perfectly fine in Disk Utility. But will not allow a repair of permissions. same is true when i boot from the OSX install CD.

i am running a Dual 2Ghz G5 running OSX 10.4.2. the external drive hardware doesn't seem to be the problem. but it is a Maxtor 250GB External HD.

the mount point for the drive is: /Volumes/liQuidAPOGEE

that's it. i am looking for a guru to help me find the "too protected" already mounted yet "invisible" external hard drive.

A quick thing to try is to run the same chmod commands you used last week so the drive shows up. Then once its visible again, do a Get Info and set the permissions properly. You could even choose to make it accessible to you only. That way other users should not be able to do anything with it.

Are you saying that you had previously changed the permissions on your external disk list the original poster?

Or is the problem perhaps that the disk's filesystem is damaged and it is not mounting?
Does Disk Utility see the disk?
Try repairing the external disk's filesystem with Disk Utility's "Repair Disk".

Hi,
Yes i had previously changed the permissions to write only and then No access, but when i tried to change it again it stayed stuck on no access

the disk shows in Disk Utility but as an unknown file, when i try to repair it i get "repair not necessary"

After i tried to change the permissions in terminal and i connected the firewire disc again spotlight started to index the disc,
In the spotlight window (show all) the name of my disc is standing by locations
spotlight also shows some of the files on the disc but as unknown files , when i try to open it the spotlight window closes

I hope you can help me out

1) What version of OS X do you have?

2) When you do File / Get Info on this disk's icon in Finder, does it have the "ignore ownership" checkbox unchecked?

3) Pick one file as a sample for detailed investigation - e.g. suppose that file is called "foo" and is in the folder called "Docs" that is in the folder "MyStuff" that is at the top level of the external disk. And suppose that your external disk is called "MyDisk".

Please launch the "Terminal" application (under /Applications/Utilities) and copy & paste the following commands, press Return, then copy & paste the results back here so we can see (change the names to conform with the actual names of the sample file you have chosen to look at):

id
ls -l /Volumes
ls -ld /Volumes/MyDisk
ls -ld /Volumes/MyDisk/MyStuff
ls -ld /Volumes/MyDisk/MyStuff/Docs
ls -l /Volumes/MyDisk/MyStuff/Docs/foo
echo ---------------

I'm using Mac Os X 10.4.4

2) When you do File / Get Info on this disk's icon in Finder, does it have the "ignore ownership" checkbox unchecked?

I can't do file/get info on the disk icon because it doensn't show up on the desktop

I couldn't remember much of the files on the disk so i had to adjuist the terminal script a bit (i hope it's still works so...) i made this of it

id
ls -l /Volumes
ls -ld /Volumes/iLios
ls -ld /Volumes/iLios/Backup
ls -l /Volumes/iLios/Backup/iPhotoBackup.dmg
echo ---------------

Then i get

Code:
random:~ random$ id
uid=501(random) gid=501(random) groups=501(random), 81(appserveradm), 79(appserverusr), 80(admin)
random:~ random$ ls -l /Volumes
total 8
drwxr-xr-x    9 random  random   340 Oct 20  2003 DISK PERMISSIONS UTILITY

ls: /Volumes/iLios/Backup: Permission denied
random:~ random$ ls -l /Volumes/iLios/Backup/iPhotoBackup.dmg
ls: /Volumes/iLios/Backup/iPhotoBackup.dmg: Permission denied
random:~ random$ echo ---------------

The above shows that the permissions on the top level folder of that disk are not correct. It lacks "search" permissions for owner.
To fix this run the following command:

chmod -R u+X /Volumes/iLios

See this Unix FAQ for more info on permissions.

Okay, try it again but preface the command with 'sudo':

sudo chmod -R u+X /Volumes/iLios

Internal "Maxtor" Drive (no access) Permission, Disk Utility, Mounted, Terminal Code

Hi hayne

Having read the posts on this topic, I have exactly the same problem as Random_d, having set the permissions to No Access also. Having never used Terminal before, could you possibly talk me through what to do. The partition I cannot mount on my desktop is the Disk 1 partition, the Software Disk partition mounts fine. Having tried one of you lines I am seeing this.

d---r-xr-x 26 Paul Paul 986 Jan 31 23:53 Disk 1
lrwxr-xr-x 1 root admin 1 Jan 31 23:19 G5 HD -> /
drwxrwxrwx 17 Paul Paul 680 Jan 31 23:46 Software Disk

I would really appreciate any help.

regards
Paul

Launch the "Terminal" application (under /Applications/Utilities) and copy & paste the following commands, then press Return, then copy & paste the results back here so we can see:

sudo chmod -R u+X "/Volumes/Disk 1"
ls -l /Volumes
echo "done"

Then restart your Mac and see if the disks mount properly.

You are a hero. After restart the disk reappeared on my desktop, with a folder icon and a little no access symbol next to it. So I was able to Get Info on it and change the ownership and permissions, and paste a new disk icon over the folder.

What did the commands actually do? And what does the sequence of symbols as in "d---r-xr-x" mean?

Before posting I had tried Diskwarrior, Techtool and also Disk Utility without success.

I have looked at your website and will try and make a donation via Paypal.

Many thanks
Paul

Its terrible, I wanted to change the permission and ownership, and by doing so, I locked myself out of my own external Lacie mini 250G.
Cannot get to it from another computer either
tried to restart my computer, and the Icon vanished from my desktop, A what U call, Phantom Drive.
I've checked out various forums, and the nearest one to it seem this one.
Next I tried the Diskutility, mounting, unmounting, etc...
Then Hayne's Tip:

The problem with the above is that your drive's name has spaces (and other special characters in it) so you will need to put the full path inside double-quotes:

ls -ld "/Volumes/Laurent's Drive"

Similarly for the other 'ls' commands. See the Unix FAQ referred to above for discussion of why this is necessary and other basics of Unix.

And as for the fix, you probably will want to run the command I recommended above. In your case it would be:

sudo chmod -R u+X "/Volumes/Laurent's Drive"

(But I'm guessing here - to be sure we would need to see the results of the 'ls' commands referred to above.)
