external hard drive locked with custom access

[TheoWB]

Ye, it's been readable for a long time, it's formated in the Mac OS-Journaled thingy or something....

[ganbustein]

Look for a physical switch on the drive putting it into read-only mode.

[TheoWB]

As far as I can see there is no physical switch on the device... what were you thinking about??

[TheoWB]

Trevor, I installed the thing you posted, dunno what it does but as far as I can see, nothing's change... what would the step be to do now...

[Hal Itosis]

mount

diskutil list

df -h

Earlier today I was trying to drag and drop a file from a portable USB drive to an internal drive on my desktop computer to over write a file. I was getting a message that said I didn't have permission to all files required, so I set out to provide global permissions to the drive. For some reason, the computer when it was finished with the permissions of all within the folder, ended up instead locking all the drives in the desktop computer MAC PRO (including the HD - I had to reinstall Snow Leopard and start computer with disk), two other internal drives and the external drive that I was trying to copy the file from.

Now when I go to access any of the drives I get an error message that says "The folder “Black_Portable_Drive” can’t be opened because you don’t have permission to see its contents." (Black_Portable_Drive is the name of the external drive). I get the same message for each of the internal drives (except the HD as I can now access that drive after booting with a boot disk).

If I try to boot without the disk, the computer will not load the OS as it doesn't seem to be able to load from the HD.

Any help would be greatly appreciated!

Plug in drives, Open terminal and type this command and copy the output back

ls -alOe /Volumes

Please let us see the results of the commands that Hal Itosis gave in post #385.

Gentlemen,

Thank you for being here! As a foreigner to the USA with absolutely nowhere to turn for any such (Apple Unix) professional advice or assistance in this country , realizing there are indeed Forums such as MacOSXHints is of enormous comfort and value.

I would be extremely grateful if you could assist me. I have to the best of my ability followed closely along with all relevant posts of this thread however remain flummoxed as to proceeding further.

What on earth or where am I going wrong? Your valued assistance is sincerely appreciated.

Genlemen,

Your appreciated assistance. Thank you

I have followed nany posts contained in this thread however I cannot escape the reply:

sudo: can't open /etc/sudoers: Permission denied

In response I typed into terminal:

sudo chflags nouchg /Volumes/"G-DRIVE 1TB"; sudo chmod 775 /Volumes/"G-DRIVE 1TB"

as ADMIN and still get:

sudo: can't open /etc/sudoers: Permission denied
sudo: can't open /etc/sudoers: Permission denied


I followed this with:

ls -alO /Volumes

Hi

Please disregard my post above - literally three days of "Nightmare Hell" - all gone in under 10 minutes...

Within Apple Discussions I found this donation-ware that solved ALL my problems in a flash - unlocked drives and partitions, corrected the "custom" permissions and owners, removed ACL's etc:

For Leopard & Snow Leopard:
MacUpdate - BatChmod

After execution be sure to Log Out and Back In and VIOLLA all those problems are a distant memory.... OH! be sure to send the developer in France a bunch of cash through Paypal!!

Hi guys,

I am brand new to this forum and not totally across inner workings of Macs eg Terminal but from what I am reading it may be the answer to my problem
I have a DROBO (USB +FW800 model) connected to a MACPRO 2.8 GHZ QUAD CORE INTEL XEON but cannot access my DROBO as it has a padlock symbol on it and when i click on it it says
"The folder “DROBO” can’t be opened because you don’t have permission to see its contents."

Ownership says CUSTOM for me , staff and everyone. Wierdly enough i cannot access from my Mac Book Pro either so feel the problem lies with the permissions in my DROBO

I did do a force quit last time i had the mac running and was trying to run "apply to enclosed folders" on the mac (i know now how wrong that was) due to another permissions problem i had encountered when setting this machine up from a time machine back up of previous mac which had been damaged

Hopefully someone can help. Thanks in advance!

Vince

Same problem as all of the guys above. Even when I try the steps suggested, I still can't get the external hard-drive to let me write on it. Its a Windows NT File System (NTFS) external hard-drive. I'm connecting it via USB to a Mac OS X 10.6.6 Minimac. Any help would be really appreciated. I already spent like 2 hours trying to write on it, with no luck.

I downloaded the BatChmod, and it does not work for me. I already tried it manually with the tips listed in the previous pages of this forums. But not even the app works to allow me to write on this drive!

Just found out why everything was failing:

Myr external USB disk is formatted with NTFS. This is a filesystem used by Windows. OS X can read this type of filesystem, but not write to it. I need to back it up, format it to FAT or HSF(mac), and then write back to it all the contents. Here is the link I used to find this out:

thanks AgentX
Luddite as i am , would this terminal command just give us an overview of the problem? Then it can be worked out what to do?

thank you and i will also read back old posts again

Hi CTAztec, was wondering would this (acUpdate - BatChmod) fix my problem re DROBO permissions?
