Drives Locked can't change prefs

Ever since upgrading to SL, my external FW800 drives have been locked to 'read only'. When I open the 'Get Info', the option to unlock or change permissions has been disabled. I can unlock the disks by running Disk Warrior, but each time I restart, the disks are locked again. Is this a bug?

hi VK, I'm also having a problem with both HD, I did what you recommended and here is the results:
1TB:
iMac:~ Daniel$ ls -ladeO /Volumes/iomega\ 1TB\ HD
drw-rw-r--+ 11 Daniel staff uchg 442 4 Sep 19:52 /Volumes/iomega 1TB HD
0: user:root allow list,addfile,addsubdirectory,readattr,writeattr,readextattr,writeextattr,readsecurity
1: user:Sandra allow list,addfile,addsubdirectory,readattr,writeattr,readextattr,writeextattr,readsecurity
500GB:
iMac:~ Daniel$ ls -ladeO /Volumes/iomega\ HD
drw-rw-r--+ 17 Daniel staff uchg 646 1 Jun 08:25 /Volumes/iomega HD
0: user:root allow list,addfile,addsubdirectory,readattr,writeattr,readextattr,writeextattr,readsecurity
1: user:Sandra allow list,addfile,addsubdirectory,readattr,writeattr,readextattr,writeextattr,readsecurity
I can acces any of them, even logging in root, could change the privileges, which are set to "custom", however I could open the drives in finder and see that the content has another privileges.
By the way, when I try to change the privileges from custom to another one, I can change it but immediately changes to custom.
Cheers,
Daniel

ThinkPad USB 3.0 Secure Hard Drive - I can not change Default admin password

I followed all the instructions from the manual guide but the password cannot being changed.
enter in admin mode, then hold lock plus 9 until led flash in blue
input a new password (of course between 8 and 16 digits lenght)
then the led flash in green three times, but then the led flash in blue and then flash in red and then in blue again as the password had wrong length.
The manual does not provide furthe action to troubleshoot.
is the device wiht defect?
Any hint would be appreciated.
Thanks,

Hello Denmark calling.
Solution for you’re:
ThinkPad USB 3.0 Secure Hard Drive problem.
In order to set the Admin pass, you will have to do the following
1. Press 0+OK for 5 sec, enter "12345678" and OK       = BLUE LED   (Admin mode)
2. Press OK+9                                                                        = BLUE LED flashes
3. Enter admin code with correct fashion, and then OK = BLUE LED flashes   (and now most important)
4. Re-enter admin code, and OK                                        = BLUE LED.
This must be done before attempting to change user password. (Obvious reasons)
For User code change.
This can be changed by accessing the admin mode first = BLUE LED
And then
1+OK                                                                                            = BLUE LED flashes
Re-enter user code and OK                                                    = BLUE LED
For User code and Admin code there is not mentioned any reference online reference supplied by Lenovo, which tells the new proud owner the correct way to alter standard codes.
But let it be said that in my humble opinion this is a (almost) great product (SSD would make the difference for me personally)
Hopes it helps

Time Machine changed my driver permissions - can't change back

Hello,
I've been using my external hard drive for about 6 months to backup my work, never had a problem.
Today I mounted the drive, as usual, and a window came up asking me if I wanted to use it for time machine backup. I clicked OK, thinking I could backup my new work, then when I saw that I would have to format my drive, I decided it was not what I needed, since I have all my old work in it.
So I de-selected my drive from the window where it asks which drive to be used for time machine, and turned TM off before doing any operations.
Since then my hard disk has become "read-only"!! Luckily I haven't lost any of my work, but I am now unable to set the permission back to "read - write". The "Repair Disk Permissions" button is greyed out.. and if I do GetInfo, I can only see it is read only, but I have no option to change that.
Any idea why time machine changed my settings before I even used it??
How can I change it back?
Thank you

I was searching on all kinds of website and I realised one thing:
Yesterday I took some files to the printer, and the guy (he was using PC) took the files off my hard drive, and DISCONNECTED the drive without doing the "Safely remove hardware".
Not it all makes sense. I should go kill him.
I rather suspect that TM is at fault. TM drives have to be formatted HFS and by what you describe it sounds like it started reformatting the drive when you stopped it.

"Documents" folder is suddenly locked, can't change HELP!!

Help!!
All of a sudden my Documents folder, in my home folder has a little "lock" in the icon and its marked "read only". The attributes ar "dr-xr-Sr-- " I've never seen the "S" before, no clue...
Nothing I do will change this. What could have possibly happened and better yet how do I fix this. It's the Documents folder and ALL the sub-folders. I've tried changing the permissions in Finder and it won't stick. Nothing I try seems to work and now I'm desperate.
Please help!
Peter

As well as the advice posted above, enter the following into the Terminal:
ls -Aol drag enclosing folder into Terminal
Both instances of l in the command are lowercase Ls. Post back with the results of the command, which can be done before or after changing the permissions on the folder. The S permission in that place means that the setgid bit is set on that folder but not the execute/search right for the group. This bit causes all items created in the folder to have the same group as the folder if the underlying file system supports this feature.

Can't mount external Hard drive and Can't change the ownership and permiss.

Hello everyone, got a problem and maybe someone here will know. Apple care can't help because this is due to an external piece. I have a hard drive external. I partitioned it into two hard drives. Long ago, I opened the information window for one of my partitioned drives. And changed the ownership and permission to "no access". I do this all the time to keep my files from being read if its not the administrator (me). Just recently I plugged in my hard drive (firewire and USB). Only one drive mounts on the desk top. I cannot see my other partitioned hard drive and I can' access it to change the ownership and permission with "apple key and I".. I can see a trace of the two partitioned hard drives when I use disc utility. But again it won't let me change the ownership so I can mount this again. How do I access my harddrive without refomatting? I have tried to mount this with both of my apple laptops..no luck yet. Please help, anyone.

Hi, Donnie. Welcome to the Discussions.
What part of "No Access" was unclear?
"No Access" means no access for anyone.
To fix this:
1. Launch Terminal, which resides in the Macintosh HD > Applications > Utilities folder.
2. At the Terminal prompt, type the following command:
sudo chmod a+rwx "/Volumes/partition_name"
where: partition_name is the name of the affected partition.
3. Press Return.
4. Type your Admin password when prompted, then press Return.
5. At the Terminal prompt, type exit and press Return.
6. Quit (Command-Q) Terminal.
7. Relaunch Finder: Press and hold the Option key, click and hold mouse button 1 on the Finder icon in the Dock, select "Relaunch" from the Finder icon's contextual menu.
You should then see the volume, or be able to use Disk Utility to Unmount it, then Mount it and see it.
Reset the permissions for Group and Other on the partition as desired. Do not change the permissions for Owner.
If you want a volume / partition unmounted at startup, see:
• this tip Mac OS X Hints, or...
• this tip on the OSX86 Project forums.
Good luck!

Hi just bought an external hard drive and can't change the sharing and permissions from read only status. How do i change it?

Hi new to macs and dont know how to change the sharig and permissions to my external hard driive from read only mode. please help

Get Info on your drive from the Finder - you'll see a dialog box like this:
If the Privilege is set to Read Only for the user, simply click on the "Read Only" and change it to "Read & Write".
Is that what you're looking for?

How can I change the BlackBerry Link Network Drive mapping from Z: to something else?

Hello,
I generally have a mapping to my NFS server on Z:, and my iTunes library has a relative path to Z: for all of my music - the fact that Link is automatically picking Z: as my network sync target for my device does not work for me to sync music, or anything really. I can't figure out how to change this value to something else.
I found the registry key: \HKEY_CURRENT_USER\Software\Research In Motion\Device Manager\Device Settings\<DEVICENAME>\VolumeMapping with a default blank REG_SZ - can I use this key at all to manually change drive mappings for my device? If so, what is the key/value pair I need and will this mess up any assumptions taken inside the Link software for synching?
... Also, I have a Feature Enhancement Request to go along with this issue: Add a "Change drive map letter" button beside the "Turn on wireless connections to my computer" button in Link, and add the same option in the context menu to the 'Device Manager' for the mapping (which currently just says 'Explore').
Thanks for the help,
- Jeff

I do not know a lot about this subject but since Device Manager is not a Device and the BlackBerry Phone is not recognized as a Device in Disk management unless Mass Storage is turned ON it looks as if by design you cannot change the Drive Letter.
Also if Mass Storage is turned On in the Phone Settings File Manager and BB link will not work but the BB Phone will then be recognized as a Device in Disk Management and the Drive Letter can be changed, this has no effect on the Drive Letters for Device Manager.
Normally to change the Drive Letter and Paths of a Device once the Device is plugged you would go to Administrative Tools, Computer Management, Disk Management, right click the Device and choose "Change Drive Letter and Paths"
Changing the Registry or Uninstalling Device Manager but keeping BB Link or looking for a Utility that can change the Drive Letter such as the one that many XP users had called TweakUI (only worked in XP) or changing the Drive Letter for your Network may be the only way.

All my hard drives (internal and external) have a small lock in the lower left corner of the icon and I don't have permissions to access. Permissions are set to 'Custom' in the get info window and I can't change them.

All my hard drives (internal and external) have a small lock in the lower left corner of the icon and I don't have permissions to access. I have 3 user accounts set up and I cannot access any of them. Permissions are set to 'Custom' in the get info window and I can't change them. Originally I had Snow Leopard installed on one hard drive and 10.5.8 installed on another. I started to have some problems accessing data between them and so I tried changing the permissions on ONE hard drive partition. The next thing I know, all my drives are locked (except the ones with the systems on them), the small lock appeared in the lower left corner of the drive icons and I don't have permissions to access any of them. In the get info window, permissions are set to 'Custom' and I can't change them.

There is suddenly a lock icon on my external backup drive!

Locked Hard Drive / Can't Change Privileges or Permissions!

My non-bootup internal hard drive (a RAID array) is locked. I don't know how it happened for sure, but I can't view any of my files or change any of the disk's privileges or permissions.
Disk utility can't un-mount the disk, but says in the "Disk Check" that everything is okay. The option to repair permissions in Disk Utility is grayed out because OS X is not installed on this volume.
I have tried using terminal to CHOWN and CHMOD the volume, but for both commands it says "Operation not permitted." When I CMD-Click the mounted drive, this appears in the info pane:
Sharing & Permissions:
Name Privilege
(Me) Custom
admin Custom
(Me) Custom
admin Custom
everyone Custom
I can't change any of the "custom" settings, whether I unlock the padlock or not. All I can change is "Ignore ownership," which does nothing to help...
I already archived my OS and re-installed 10.5, then upgraded to 10.5.7 and still no luck. I'M TOTALLY STUMPED! Any ideas?

Okay, it looks like I've solved the problem. After LOTS of searching, I found a discussion that led to the solution... I first ran this command in terminal:
ls -alO /Volumes
This command revealed that the "user immutable flag" was set (the text "uchg" appeared with the problematic drive) and permissions looked odd. The following commands fixed both problems:
chflags nouchg '/Volumes/<drive name>'
sudo chmod 1775 '/Volumes/<drive name>'

My system drives locked up -- "custom" access can't be reset

My system crashed and it took be a day and a half to get it working again: Lion wouldn't reinstall from the DVD, from the internet or from the Lion USB stick I made. Finally I pulled out all the drives and put in only a Lion drive I had set aside as a safety. This worked.
My main system drive and the Time Machine drive display a little lock icon and when I open Info, their permissions are all listed as "custom." Worse, when I try to change them, I can't.
All my data is on those drives and Lion won't even let me open them to transfer files.
How do I change the permissions?

I've been wrestling for three days with being locked out of all drives except one. I've tried everything on the planet including variations on the following, with no success. I was stunned when these two simple commands, cut and pasted into terminal, worked. I repeat this from the archives since it took me ages to find it among all the other posts that were efforts to help. Frame this, bronze it, put it on the wall, worship at its feet. I'm not sure I'll ever be able to relax using my Macs again. V.K., you're a god. How about visit a bolt on Cupertino.

Re: Drives Locked!
Feb 8, 2010 10:52 PM (in response to CMathis)
run the following terminal commands (copy and paste, please)
sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*
you'll have to enter your admin password (which you won't see). that's normal. this should unlock your drives.

How can I change the source file so it is direct from external hard drive?

I am trying to make a movie on imovie of a snowboarding trip that I went on, there is around 80 to 100 gig of mp4 movies that will not fit on my computer that I have stored on my external harddrive. I had the movie half finished then found I could do no more as I had no space left in my mac. I had to delete everything and start again but I'm not doing this until I can find a way of changing the source file so I can take them direct from my external hard drive as to not use up all my computers available space. I have moved imovie to my external hard drive but it still tries to read from a movie file on my mac, how can I change that so it will read from a source file on my external hard drive, is it possible?? Can someone help me??

Hi Bengt, Thanks for your input, much appreciated.
I have a WD 1TIG hard drive and are using usb connection, is it possible to use fire wire with these? I have had trouble with a lot of the videos I Imported, once they downloaded the file in the viewer window showed up blank and when I mouse over them it places a picture of another file in the window and wont drag and drop into the movie window, like their corrupted or something? Had to delete just about all of them and start again. Also is it possible to select a bunch of videos in the viewer window as to change the dates to the correct dates? All I have been able to do is "select all" which is no help.

How can I change the default driver to OracleXADataSource in JDeveloper

Hello,
How can I change the default oracle driver: oracle.jdbc.OracleDriver to oracle.jdbc.xa.client.OracleXADataSource in JDeveloper Studio Edition Version 11.1.1.0.2, Build JDEVADF_MAIN.BOXER_GENERIC_090328.0229.5205.
If I modify the file connections.xml from jdeveloper\system\system11.1.1.0.31.52.05\o.jdevimpl.rescat2\connections in the sense that I change the driver class, then in JDeveloper when I test my connection I have this problem: Test failed: oracle.jdbc.xa.client.OracleXADataSource cannot be cast to java.sql.Driver
Why do I need this XA version of the oracle driver? Well I tried, from a book to reproduce the model of an application: entities, stateless and stateful session beans, mdb, web services and a client to test one part of the model.
And because of the JMS server I need an XA driver.
I deployed to the integrated wls 10.3 and when I test my client, if I use the default driver for the connection the an error message appears tell me either to emulate two-phase commit or to use XA driver.
My application works very well, if I configured in the console of the integrated wls 10.3 a datasource with the same name as my ide/application connection that has for the Driver Class Name: oracle.jdbc.xa.client.OracleXADataSource in the Connection Pool tab.
Thank you.

Open DIsk Utility and in the toolbar select Disk Image. The file selector will open and you'll have to do three things: 1) just as with any file, name it and point the file selector to where you want it to be saved, 2) near the bottom you'll see name - type iWork 2013 and 3) below that select the image size. Click on size, choose custom and type 1500 MB then click on the Create button.
Some time will pass and then you'll see an external disk pop up on your desktop and/or the Finder window sidebar. Drag the three programs into it and eject it like any other external disk. Now delete the programs from your applications window.
Where ever it was you pointed the file selector to you'll see the file you created. Double click on it and the disk image will mount again.

My iPhone is locked to ex's iCloud account (but to my credit card!). I don't have the password. How can I change it to my new iCloud account?

My iPhone 4S (iOS8) is locked to ex's iCloud account (but to my credit card!). I don't have the password. How can I change it to my new iCloud account?
My phone shows my name plus iCloud old iCloud account. My kids' new iPads show my name plus my new iCloud account. But both accounts show my children as "family" associated with them.
Basically, I need to change the iCloud account on my phone to my new one. But I'm not given that option.
Help and thanks.

Hi and thanks. The password on the old iCloud account doesn't work and my ex-husband says he doesn't know what it is -- and that he's not getting emails to reset the password. I tried using the rescue questions and even the birthdate isn't working. I think he's changed it to keep me out, but it's charging my credit card account.
