External HD permissions?

I have an external HD connected but I do not want to format just yet. How do I allow permission to remove things off of the external HD? It keeps telling me that I cannot do so.
Any ideas?
When I looked at the disk utilities it is showing the drive as read only.

Hi IBG2,
most likely the HD is coming from a Windwos PC, right ?
Use Disk Utility or get Information in Finder to verify that the HD uses the NTFS file system.
OSX can only read from NTFS drives not write from them and therefor can't delete anything on it.
You have to reformat the drive using HFS+ (OSX file system) or FAT32 (MS-DOS in Disk Utility) if you need it to connect to Windows PC also.
If you don't want to reformat you can use Paragons NTFS for OSX for full access http://www.paragon-software.com/de/home/ntfs-mac/

  • Can't Read/Write to External HDD-Permissions Problem

    I have external Seagate HDD, formatted as FAT32, connected to Airport Extreme Base Station. I am unable to Read/Write to this Drive because Finder says I "Don't have permissions" to do so.
    Following are details that may be important:
    1. I was able to read/write to this drive under Leopard but lost the right under Snow Leopard, after upgrade to SL.
    2. In Airport Utility, I set up (2) accounts for the External HDD, "Dad" with "Read/Write" access and "Mom" with "Read" access only. I have Guest Account privileges set to "Read Only". It has been this way for (2) years.
    3. Under "Get Info" in Finder, the only account listed is "everyone" with "read" permission only (this is same as Guest Acount in Airport Utility). I am unable to add new accounts because I get error message "The account name is not valid" even though I am using the account name that I am logged in under.
    4. I can change the Permissions on the "everyone" account (in Finder) by changing the permissions on the "Guest Account" in Airport Utility. When I do this, "everyone" in Finder now has "read/write" access but my two accounts, "Dad" and "Mom still don't show up in Finder.
    5. I also upgraded internal HDD to 1Tb and used Restore from Time Machine. I hhad problems with the restore and did new install of Snow Leopard.
    Any ideas on how to make Finder show the two accounts I have set up in Airport Utility?

    My apologies for bumping this but I still don't have a solution...any help would be greatly appreciated!

  • External HDD - Permissions

    Hello everyone,
    I share an external hdd and the files on it with a lot of people. What ails us: the whole permission mumbo-jumbo.
    Is there a way to automatically strip all permissions (or like chmod 777) and the ownership from a the file, when it's copied to the ehdd?
    Thanks!

    As BaconPie said, change the fstab of every computer that connects to the drive.
    create a line for your usb drive or add to the existing line _one_ of the following in the options column:
    dmask=0222,fmask=0333
    umask=0222
    uid=1000,gid=1000 (check with the 'id' command that this matches your user and group id)
    You might also want to add the option 'user' to allow you to mount and unmount that drive without being root.
    Lastly, you are able to write to the drive right? Else see https://wiki.archlinux.org/index.php/NTFS_Write_Support

  • External Drive Permissions Locked to Read ONLY - HELP!

    Hello:
    I have recently moved from a powerbook to an imac. The external I used with the powerbook was working fine until I began to use it with the imac. Once I hooked it up to the imac, I only had read permissions. I have never set any of the permissions on the disk and have always left it open. Thinking it was just the imac, I plugged it back into the pb, to find it was also appears locked to read only. I have gone through the web looking for solutions and I cannot seem to find a solution.
    When I open get info about the disk, under sharing and permissions, its says "you can only read"
    under the list of name: wkim has read and write privlige, staff and everyone get read only. I am wkim, so what gives? Any help would be greatly appreciated!

    ok. my problems were probably not related and were fixed by reinstalling 10.5.2 with the Combo Updater found on (www.apple.com/downloads)...this probably won't help you but won't hurt so may be worth a try...
    your permission problems probably have something to do with user IDs changing from one machine to the next. Try first to "repair permissions" with Disk Utility on your main HD. you can also go to Terminal and navigate to the problem directory and enter "ls -ln" to see what user ID and group ID own the files. then type just "id" to see what your local ID is. if they don't match then you'll probably need to change them with chown or chgrp.
    hopefully someone else will chime in here as 10.5 has created convoluted permission problems and I still haven't worked out my own...

  • External HD Permissions over network

    I have a mac formatted external hard drive on my mac pro system. Via my wireless network I have a macbook pro connected to the same hard drive. I can read, but can not write.
    The permissions are all set to read and write for everyone, and the ignore permissions box is unchecked. No matter what I do, I get an error that says I don't have the required permissions to copy a file to that drive via the network.
    Any ideas?

    Hi azaxman, and a warm welcome to the forums!
    Try checking that Ignore Permissions box, if that doesn't work, the easiest way is likely With Sharepoints...
    http://www.hornware.com/sharepoints/
    Explicitly choose that Drive as a Share, then set Perissions how you like.

  • Need help repairing bootable external drive permissions

    I, like some of the other posters I have read, have messed up the permissions on a bootable external drive.
    I don't have direct access to my home computer right now so I set up an external bootable copy of my personal account, so I can basically run a copy of my own personal computer from anyone elses mac. And when I get back home I will be able to copy back across any new files.
    The set up was working great till I realized that my external drive was completely readable, and writeable by anyone who turned it on as a peripheral disk while logged in on the main computer if the computer was booted up on it's own startup disk.
    If my external was set as the startup disk, then my password and account kept everything secure.
    So anyway, not really knowing what I was doing I, using the show info command, changed the group permission for the whole disk/volume from admin to my username. Now unfortunately I cannot startup using my external disk; the whole system goes straight to Kernal. And all my files are still totally assesible to any one logged in on the computer using its own start up disk.
    Can you help me with the commands, to first repair the group permission so my disk is bootable again, then second so that I can prevent anyone with out my password access to any files on the disk?
    Thanks alot!

    Can you help me with the commands, to first repair the group permission so my disk is bootable again, then second so that I can prevent anyone with out my password access to any files on the disk?
    On another machine, open the Disk Utility in the /Applications/Utilities/ folder, select your drive in the list of disks, and then click on the Repair Permissions button; other solutions are available if this doesn't work.
    Your two goals are mutually exclusive; there is no way to restrict access to an entire disk to yourself while maintaining the ability of that disk to boot Mac OS X. Your home folder can be protected in this way by changing the permissions on the item inside /Users/ with the house icon, or by turning on FileVault in the Security pane of System Preferences.

  • External HDD permissions differs from Mac and Win

    I just bought an external Hard Drive LaCie which asked at the first setup if I was going to use it for Mac, Windows or both.
    Of course, I picked both as I will be moving around with it.
    I can read, write on Mac. However, I only can read on Bootcamp.
    I was not able to change the permissions on the Windows side (right button on the HDD does not display me any permissions options like mentionned in my research).
    In my permissions on Mac, everything in Read & Write.
    PLEASE HELP, it has been driving me crazy
    Cheers,
    PacoSG

    Easy fix, this will erase everything on it no other way
    Connect to OSX, open disk utility, select external drive on left hand side
    Click partition tab, select 1 under options - this is KEY - change to MBR
    Format will be exfat
    Run it

  • Problems with external storage permissions

    When i plug in an external storage i don't have read write permissions as user. Is it correct to run chmod -R 777 /media and chown -R du:users /media to solve it? (du is my username)
    Last edited by jacopastorius82 (2010-12-08 09:55:09)

    By default if you plug in a usb storage device only an item in /dev is added, but nothing mounted. The permissions and mount point depend on the application that does the actual mounting (pmount/udev/thunar/.../).

  • EXTERNAL HD PERMISSIONS PLEASE HELP!!!

    My Friend Changed Some HD Permissions on His Computer while my HD was connected... Now I don't have permission to access it, and it won't let me change the user permissions, even when logged into root.
    PLEASE HELP!!!

    Hi DJ Young Dirty;
    You might want to find better friends in the future.
    Do you have a backup?
    As far as your Mac goes are you able to change the permission if you boot with original DVD that came with the Mac?

  • Changing external hardrive permissions.

    i recently had to erase my harddrive and restore from a time machine back up. however, once mountain lion was reinstalled i did not restore right away and instead created a new user account on my harddrive. let's call this account "p". i then i used migration assistant to restore to my original system, account "x". my computer now has both accounts on it and my external harddrive is now linked to account "p". when i am using account "x" everything on my external is listed as "read only". if i use account "p", the account that i don't want to use, that has none of my applications on it, and created by mistake, everything is "read & write". how can i fix this?! thank you!

    When logged in as x, select the external drive, choose Get Info from the FIle menu, and either give yourself write access to the drive or set it to ignore ownership.

  • ExFAT external drive permissions problem

    Hello,
    I have a new iMac running Mountain Lion. I have setup an external drive (iomega 1TiB) with two partitions, one for time machine, the other for sharing and storage purposes formatted with ExFAT. Few days ago, both partitions went unexplicabily into read-only mount mode. While the time machine partition had low occupation I just reformatted and restarted time machine. The other partition I would like to solve without reformatting as I don't want to copy everything to the iMac and then move it again to the external drive. Moreover, I'm afraid it will happen again. Any hints on why this happened?
    Thank you
    RL

    I've tried everything I can think of to reformat this disk.  Originally it was formatted for MSDOS but reformatted for the Mac.  I can access the files on the drive but I don't delete them or erase the drive and reformat.  I can't partition the drive.  Everything is greyed out.  I've tried booting to recovery drive and trying to reformat it there wihtout success (still all greyed out).  At a loss to understand.  Verify reports it to be okay:

  • Exchange permissions between 2 domains, separate forests

    We have a partner division on our network, they have thier own domain(s) but we provide email for them. We have no control over thier domain at all, we have a two-way trust and thats as far as our connection and access goes.
    Our Domain (A) has accounts and mailboxes, we add thier users to the mailboxes using associate external account permissions (Exchange 2003).
    Domain (B) is thier users accessing mail using outlook. Working well at the moment.
    Exchange 2010 migration - from Exchange 2003,  some accounts were not migrated as Linked Mailboxes, we need to convert them.
    Here is the question:  What permissions do we need on Domain B if any, to be able to carry out mailbox additions (linked mailboxes) and conversions of the few that need it.   Domain B owners are reluctant to give us any rights other than a basic
    user (AD read).

    We setup a domain user on both partner domains, when using the create mailbox and the linked conversion powershell commands this was enough permission to do what we needed.  Least is best!  just a read only account needed in their AD to create
    mailboxes in our domain.
    Perfect!

  • Sharing iTunes on a single computer with multiple users

    Greetings,
    I have been troubleshooting a problem sharing iTunes on a single computer with multiple users that cropped up a few weeks ago and have not had very good luck.
    Several months ago I successfully set up my wife’s G4 Laptop (PowerPC processor) so that we could share iTunes on that computer. I had just gotten her an “My Book” external hard drive (Western Digital). The iTunes Library will go on this new unit because the internal drive was running out of room. I successfully set the privileges, moved the entire library onto a “Share” directory and everything worked fine.
    In this way, when I got a new CD I could add it to iTunes (under my login, administrator privileges) and she could access it (under her login) to listen to while working on the computer or using her iPod. This arrangement went well for quite awhile.
    About a month and a half ago, when I tried to launch iTunes from my login I received this message:
    “The iTunes Library file is locked, on a locked disk, or you do not have write permission for this file.”
    I think the permissions must have changed when there was an update because my wife is pretty careful about what she does on her computer. Updates were the only thing I could think of that had changed since I had set her computer up. I also noticed that some of the iTunes defaults were different from the last time I had used it to add a CD.
    So, I did some reading and went back through the motions of trying to set it up again. I re-formatted the My Book hard drive to Mac OS Extended (Journaled) added the files back to the external, reset permissions on the external hard drive. (Owners: System, Access: read and write - Group: wheel, Access: read and write – Others: read and write).
    When I now launch iTunes under my login I get this message:
    “The operation cannot be completed because you do not have sufficient privileges for some of the items.”
    What gives? I am the original owner and have always had top-level privileges.
    Can someone point me to any articles or clues as to how I need to set-up iTunes on a single computer to be shared by more than one user? Also, I am considering upgrading to the newer system in a few weeks, so if a solution for OS X 10.5 is available, that would work too.
    Tim

    Was your wife logged into the libray at the time you tried to log in? I have had a similar problem and it was because another user was logged into the library when I attempted to. I got the permission denied banner.

  • After installing 10.7.2 from scratch, permission errors remain

    Hey, this is a summery of what have happened:
    1. upgraded to Lion from SL (via AppStore)
    2. have played with 'get info' > 'apply to all enclosed items'  :/
    3. things have gone messy, slow, permission errors. example:
    (Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.)
    4. booted from DVD of Lion dmg.
    then, formatted and performed a clean install.
    (backed up to a new disk image with CCC, just in case)
    5. Notice that I did not copy anything or downloaded/installed a single file/application yet.
    after the so called 'clean' install, I've ran the disk utility to verify permissions again (both from DVD and from cmd+R - recovery partition).
    still I get the warning about ARDAgent, still verifying and repairing permission takes 2-3 minutes. with only the OS X installed on HDD.
    6. Got this advice from several boards:
    Open Terminal as an admin user.
    type in the following:
    sudo chmod -RN ~
    you will have to authenticate with a non-blank password.
    then follow the steps of resetting the ACLs.
    I have done this, and got: Failed to clear ACL on file ubiquity.socket: Invalid argument
    Then, booted from DVD, in terminal typed: 'resetpassword' and chose the HDD and "user" and clicked on 'reset password and ACLs'.
    restarted, Spotlight did index againg.
    7. still permission errors, so I didn't copy anything back yet, waiting for help to get the right way or restoring to default/formatting again.
    My questions are:
    1. Did I do everything right? Is it possible to perform a clean install from the DVD that I made?
    2. If so, shouldn't it cancel all the ACLs problems and reset them to the default?
    3. Is there a way to make a real 100% clean install of 10.7.2, with erasing even the recovery partition (if it has to do with ACLs)?
    4. if and when this will be solved, I will need to copy back my files and folders from external FW800 WesternDigital,
    will I need to reset their permissions too somehow? It could cause more problems with the ACLs.
    thank you very much.

    baltwo,
    I have a lion clone. so I guess there is no reason to install lion upon it's own clone.
    anyways, how is it possible that after the complete format, the ACL problem remains.
    what about removing the recovery partition.
    the reason I want it to be done is to get rid of the problems I had with the new installation, tham I'm afraid will not be fixed otherwise: crashing apple applications (safari quitted unexpectedly), slow performance, computer freezes, GUI lags (copying 138 items to another folder stucks and I have to relounch finder) and other animation bugs at almost everywhere on the system.
    restoring lion clone and turning on the time machine sounds like the last option right now...
    and I'll be happy to hear opinions about what to do with the backed up data on the external hdd permissions.

  • Hard drive and windows 7

    I brought the Toshiba PX 1394u external hard drive. It worked amazing on my windows XP computer however i recently moved and brought a windows 7 laptop, and my hard drive doesn't want to work as well as it did on my windows XP (unable to copy files and at times doesnt recognise it). It works on my xbox 360 but not my laptop.
    Is there ainyway of getting my hard drive to work with windows 7?

    Is this an NTFS drive? If so I think you have an issue with its security settings. Pull up the properties of the drive and click on the security tab and look at who can do what - I expect you will see "names" relating to your old laptop. I would suggest a google for "NTFS external drive permissions" and I would expect you will find some step by step guides to sort it.
