external hard drive locked with custom access

[Atmabhav]

Regarding the above post here is the results of ls -alOe /Volumes
id
diskutil list
df
echo "done"

MBP and HD are the disks in question. MBP is my macbook pro which I've accessed via firewire on my flatmates imac. HD is an external drive with custom permissions.

The external is easy to fix. Terminal Command.

sudo chflags nouchg /Volumes/HD

drwxrwxrwx 35 lyndamills staff - 1258 13 Oct 21:40 MBP
However it looks like you have tried to reset permissions on boot drive (MBP) manually already and probably messed up permissions on whole disk if you used "apply to enclosed items".Did you try and fix that ?

Permissions on boot drive should be

sudo chown root:admin /Volumes/MBP ; sudo chown 775 /Volumes/MBP

Then run permissions repair on MBP in disk utility and cross fingers !

The external called "HD" will need additional changes (due to drw-rw-r--). And there is an error in the "MBP" part (the second chown should be chmod).

To summarize...

sudo chflags nouchg /Volumes/HD
sudo chown 0:80 /Volumes/MBP
sudo chmod 775 /Volumes/HD /Volumes/MBP

[agentx]

@Hal, I am under the impression that when you remove the uchg flag the execute bit comes back.

Yes the chown should have been chmod. Doh !

Nope... two different animals altogether. [e.g., did you also think that locking an item would undo a file's ability to execute or a folder's ability to be viewed?]

I have read through this thread thinking that it might be the place to find the solution to my problem...however I am really not all that advanced with command prompt and my mac...so I do apologies if this it the wrong place for my question or if it has been answered else where.

I will be as concise as possible:

Mac details:

MacBook Pro
2.2 GHz Intel Core I7
4 Gb Ram
OS x Version 10.7.2

External HDD:

Maxtor Basics Desktop Media 1.5 TB

Partitioned:

200 GB time machine
1.3 TB Media etc...

Problem:

I was copying a folder of music (aprox 70mb) over to my HDD for back up. After 5 min the file transfer appeared to have crashed at 99%. I decided to eject the drive in an attempt to re-boot it, however it would not allow me to eject.

So in a naive manner I yanked the cable. Re-inserted and it appeared to load fine. Both drives were displaying on the desktop however when I went to open the media partition, the screen flickered and crashed the file explorer window in finder. I can however access my time machine drive with no issues. I have tried disc utility to repair and verify, however this has not solved the problem.

I have tried the drive on a windows PC and it allows me access to the drive and all my files and folders are still there. plus I have also managed to drag and drop files on to the drive icon and copy files to the drive.

I have tired all the steps "sudo chflags nouchg..." with no result.

Any one got any ideas?

I have a similar situation to the others here. My only difference is that the drive in question is a NAS, and I'm not sure what kind of an impact that has on any of this.

I have "custom" permissions on all of the files located on the NAS. Some of the directories allow me full access to rename, copy, add in files, take out files, etc. While others completely lock me out from anything but reading the files.

I am confused to say the least. I have tried to change the permissions (if thats even the problem) on several of the files, to no avail. I'm just kind of at a loss after hours of searching and trying things that I've found Please help ;(

Dear Trevor,

If you could walk me through this that would be amazing. I have read through your post and feel like I need some help to fix this.

I am running on a Macmini.

I have a Maxtor External Hard Drive that I use as a backup (not the bootable one - but the other drive). In trying to get multiple computers to connect via file share or bluetooth, I set permissions in the Get Info window of the Maxtor (admin - Read & Write, staff, everyone - all have read and write permissions) and then hit "Apply to enclosed items"....after this when I reopened the GET INFO window, the permissions still SAY "Read & Write" but above the Name/Privilege tag (and under the Sharing & Permissions: there is a line that says "You can only read". When I try to uncheck "Ignore ownership on this volume" I get the following error message "The operation can't be completed. An unexpected error occurred (error code -8076)."

I am now backing that drive up onto another drive because it has all of our nonprofit files on it. I am in Nicaragua and have no other access to IT help.

Thanks so much for any help you might have!

hello, i am not sure if any one can help but i am computer illiterate but hope someone can help, and explain in detail as i probably wont understand.

I cant access my external hardrives iphoto library, but can access other folders within it. This external hard drive was used to recover all my information off my old computer that died, (sorry i dont know the technical name). When i plug it into my mums computer (also a mac) and click on more info it comes up with me - Read and write
staff - read and write
everyone - read only

but when i go into my iphoto and click on get info if comes up with:
me - Read and write
staff - read only
everyone - read only

Also when i put in ls -alO /Volumes into terminal this comes up:

Hey, new user here, read enough of the thread to understand bits and pieces... What is wrong with my iPOD in the following case:

I cannot restore the iPOD because of a read/write error...

@granti_boy

Generally you do not mess with permissions on iOS devices.
You need put device into DFU mode and restore using iTunes to get things back to normal.
Once done you can either restore your data from backup or reconfigure the device from scratch.

there are loads of links and tutorials when you google ipod or iphone DFU mode.

I have a MacMini running Leopard 10.5.8 and have 3 external storage devices.

Yesterday, I turned on the one with my media files, Samsung Story 1GB, I got a warning.

screen1.JPG



Then, I tried Disk Utility but repairing options were grayed out except Verify Disk.



screen2.JPG



When I tried that, I got another warning. (I tried to get the screenshots)

screen3.JPG



When I click "Get Info" on the Samsung, everything is grayed out.



I can access the files, but can't edit or move any of them.



Going thru some forums, being very unfamiliar with Terminal, I nevertheless entered

ls -alOe /Volumes in the Terminal screen and got the following.

james-belgins-mac-mini:~ jamesb$



I can't reformat the disk as I would lose all data. The free space on my Mac's hard drive is not big enough for copying all files and I have no way of getting a new external soon.



Can anybody help me please?

[agentx]

Has the Samsung got a system on it ?
Ie. do you clone your system drive to it ?

Just remember one copy of data is never enough unless you are fine with losing it !

Overall if no system is on the SAMSUNG run this command and see if you get R/W access to your drive again. It looks like the ACL (access control list) is not letting you write.

sudo chmod -RN /Volumes/SAMSUNG

This command will remove all ACLs on all files and folder on drive.

Hello everyone and especially Trevor!

Here's my major problem:

I bought a second hand PPC G5 Leopard 10.5.8 installed.
After working on some files I discovered I didn't have certain permissions to perform tasks so I changed my whole internal HD with the "Get Info" pane.

After this I was locked out of all HD's, and couldn't even restart my mac. It stayed on the grey apple logo screen, fans roaring and all...

After reading a lot of posts here about the problem I discovered I have been really stupid changing permissions through the Get Info pane but still need help very very bad.

Point is my external LaCie drive (USB) is also locked for me. All my digital legacy is on there!

Please, please give me a clue on how to unlock my LaCie at least....

I will see how to do the other HD's when we get this one rescued. The other ones still being in my mac at home. I can't show you the Terminal results from these as it doesn't even startup anymore...

The LaCie is now at my workplace to be rescued.

Here's the result of the ls -alO /Volumes command:

I can see uchg in the output that you posted above.

If you reread this thread slowly and carefully, I think you will find the help that you seek. Many persons far more knowledgeable than I have contributed to this thread.

So, slowly, carefully.

Ufdah! That will destroy your operating system installation.

I've got to say that this time, though, it's a blessing in disguise. When you buy a second hand computer, you always always need to install a clean fresh operating system on it. You have no idea what the previous owner or owners installed on it, and it could be filled with malware, either purposely or because of a lack of knowledge of the previous owner(s). So, you'll need to reinstall OS X.

No problem. Connect your external LaCie to a different Mac (or this Mac after you've clean-reinstalled OS X), and issue the following commands:

sudo chflags nouchg /Volumes/FILES
sudo chflags nouchg /Volumes/FOTO&VIDEO
sudo chflags nouchg /Volumes/HD\ BACKUP
sudo chmod 775 /Volumes/FILES
sudo chmod 775 /Volumes/FOTO&VIDEO
sudo chmod 775 /Volumes/HD\ BACKUP
ls -alOe /Volumes
echo "done"

Because of the 'sudo', you'll be asked to enter your administrator password at the text prompt. Do so. As you type the password, nothing is echoed back to the screen. This is normal when entering passwords on the command line. Just type it blind and hit Return when you're done. If you've never used the sudo command before, you'll also get a warning about it's usage. This is normal too, for the first use of sudo only.

Trevor

[trevor]

Oh, and let us know what the results of the ls -alOe /Volumes command (in that list of commands immediately above) are. You only showed us the results of ls -alO /Volumes before, which means that there may be hidden ACLs that could still be problematic for you. This thread was started in the days before ACLs were built-in to OS X, so the appropriate command has changed over the years.

I've been reading pages of this thread for at least an hour, trying to learn how I might get my external NAS (an HP MediaVault) to unlock all the folders and files in the /Volumes/Backup which are now saying I have "custom access." I can mount the drive, see the files, copy the files to my desktop, etc. But I use CrashPlan to backup my MBP to this NAS, and since I installed Lion, for some reason these permissions problems are (so sayeth CrashPlan) preventing CrashPlan from backing up to the drive. CrashPlan support was really nice, but couldn't solve the problem, saying it was Apple's issue, or HP's. Apple support was really nice, but couldn't solve the problem. HP doesn't support this NAS any longer. I have reached the end of line...I'm grateful for any help!

I have tried a bunch of commands:

• sudo chmod -RN /Volumes/Backup/ -- I get lots of chmod: Failed to clear ACL on file /Volumes/Backup: Operation not supported
• chmod 775 /Volumes/Backup/ -- doesn't work
• sudo chflags 0:80 /Volumes/Backup -- doesn't work
• etc.

I'm overmatched...thanks for any help.
