[SOLVED] external hard drive permissions

I have a seagate external hard drive (/dev/sdb1), formatted as ntfs. Whenever i try to make something in the drive, or copy something, i get a Permission Denied error. How can I give rw permissions?
I have tried searching around, but i can't find an answer that will work.

Have you installed the driver to allow you to write on ntfs filesystems? I use ntfs-3g (http://wiki.archlinux.org/index.php/NTFS-3G).
Maybe you can find something that may help you out at the thread: http://bbs.archlinux.org/viewtopic.php?id=94863.

External Hard drive Permissions changed to "read only"

I use a Seagate Slim Drive (500GB) on my Macbook Pro (Late 2012, Retina, 13"), to store movies and tv shows and whatnot. Last night, I was watching a movie and everything was fine. I ejected the drive after use and it stayed that way overnight. This morning, I tried to connect it, but the partition refuses to mount. I got a friend to help me run command prompt diagnostics using terminal, which revealed that the permissions had suddenly changed to "read only". I really need to access the data on this drive because some of the movies in there are part of an important project that could hopefully land me job. Any help is welcome.

1. Select the external hard drives icon
2. Right-click > Get Info (cmd + i)
3. Expand the Sharing & Permission column
4. Click on the lock at the bottom right
* You will be prompted for an administrator name and password *
5. Once unlocked change the permission for user, group & everyone to read & write
6. Click the little gear right below and select “Apply to enclosed items…”

Can't update iPod - external hard drive permissions error

I'm trying to change file permissions on an iTunes folder on an external hard drive. I'm able to get to the folder, but when I open the documents info screen, the Ownership and Permission section of it is disabled and I can't change it. I'm the administrator of the computer- there are no other users other than me, so I assume I can change permissions for a folder.
The problem is that all the easy options (I'm no UNIX tinkerer) are grayed out. I don't have the option to lock/unlock, change permissions, etc... because there is no way to access these options. See the screenshot of the folder here:
http://digital-goddess.com/img/itunes_screengrab.jpg
I have tried changing permissions on the parent of this folder and applying to all subfolders, but that didn't change this folder or my access to it. This folder holds half my iTunes library and throws up an error that I don't have sufficient permissions to update my iPod. This is very annoying and worrisome. Any help?

Sorry, I forgot one step.
When you expand 'Details' a button called 'Apply to enclosed items..' appears. Click on that to apply all permissions to the files inside the folder.
You can also use a free (donationware) utility called BatchMod to set the correct permissions.
Hope this helps.

Edit:
Just realized, you have that folder on an external HD.
Apply the Ownership & Permissions to all contents of the drive to prevent possible trouble with other applications.

Partitioned External Hard Drive - Permissions.

I have an external hard drive that is partitioned into two volumes. Recently one of the volumes has not been showing on the desktop. I tried repairing and verifying the drive with Dick Utility (this second partition is visible with a generic icon) and says everything is okay. I think this might be a permissions issue - this problem appeared shortly after changed volume permisions for differnt users. Problem is no user can see the drive (Admin or others). Is there any way to revert, delete or fix this so that I can access the second volume?

External Hard drive permissions

I have a 4 TB external hard drive which is formatted as NTFS - when I load it on my mac I can only read the drive and cannot edit, add, delete etc. therefore obviously making it useless!
This problem hadn't occurred to me before purchasing my mac so I guess I have 2 questions,
1. Is there a single format that I could use which would allow me to read and write on my Windows PC and Mac.
2. Is there a stable and reliable way of changing the permissions on this drive so that I can read and write on both my mac and PC? Also as it is several TB in size and I do not have a larger drive to back it up to is there a way I could do this without losing the data??
Thanks

Great I'll try formatting it to that - will I be able to use Disk Utility to do that??
I've downloaded paragon which has worked a treat for now but I don't particularly want to pay for it... needs must perhaps though.

External hard drive permissions frozen to "read only"

Hi
I have an external hard drive (windows formated) and I am using it on my imac but the permission won t change from read only
I need to copy files into it and I can't right now...
Thanks for your help if you have an idea!

If it's in the Windows NT filesystem, you need to install a driver such as this one or reformat the drive, which erases everything on it.

[Solved] External Hard Drive mount point in fstab crashes launch

Hi there,
I have an external hard drive that I'd like to automount when I plug it in. Sometimes it seems to work, but other times I have to manually mount it. In order to make this a little easier, I copied the mounting info into my fstab file so that I could just run:
mount /dir/to/mount
However, now I can't actually boot up my machine unless the external drive is plugged in. I get some error from systemctrl saying one of the drives couldn't be loaded.
An obvious work around would be to write a one line script that mounts the drive for me, however, I'd like to learn how to do this correctly. I think the rules have changed a bit with systemd, as I didn't have this problem a few years ago.
Thanks for the help!

Thanks for the answer, that fixed it.
You're welcome but I think Mr.Elendig's post gives the actual solution (my proposal is just a workaround -- using fstab for a filesystem that is not permanently attached is sub-optimal)

How do i get my external hard drive permissions changed from read only to read and write?

Does anyone know how to get an external drive to unlock the permissions from read only to read and write? Without reformatting or buying an app?

Hey P,
If you single click on your external drive icon on the desktop and then goto
'File > Get Info' a window will display the information for that drive. At the
bottom of the window their should be a check box that either allows you
to recognise users of not. You probably want to uncheck this box.
Or... You can keep the user option and just change the permissions
using the same Get Info window.

External hard drive permissions - altered?

I attached my (relatively) new external HD to do a full time machine backup after installing Yosemite, but the backup was refused as the drive was listed as "read only." This is a Mac OS extended format and I have been using it for about a month with no issues. It was not a read only drive before. Disk Utility will not allow me to change the permissions. My questions:
1. Why is my external HD now read only?
2. How can I change it back so I can do backups again?
thanks!

Hi John,
If you are having an unexpected read-only error on your Time Machine volume when trying to back up, you may want to try the troubleshooting steps outlined in the following article:

[solved] External Hard Drive Not Recognized

I bought a SATA-to-USB 2.0 external HDD enclosure today (found here), and plugged in a 320gb WD Scorpio Blue. When I first plugged it into my laptop, with Crunchbang Stalter on it, it worked perfectly. I partitioned it and everything. However, I then plugged it into my desktop with Arch on it, kernel version 3.4.4.2, and it was not recognized. lsusb returns nothing related to it, fdisk -l does nothing, and dmesg only displays "fuse init (API version 7.18)". I have tried multiple file systems, set up on my laptop, including ext4, fat32 and ntfs, with absolutely no luck. I would greatly appreciate any help.

I was actually having the same problem with a USB to SATA adapter that only occured on my arch box. When the device was plugged in it showed the event in dmesg and then it got registered as /dev/sde. If I tried to use the mount command though it gave me some error like "could not read from inode" or something like that. After upgrading to kernel 3.4.4-4 the problem seems to have corrected its self now. Are you using systemd or udev?

Permissions problem when copying files from external hard drive

Hi.
I have recently reinstalled leopard (wiped the hard drive clean) on my macbook pro. (10.5.4). I had used Time Machine so I have a complete backup. But I only wanted a few of the files so I didn't do a backup restore. I went into the file directory of the backup on my external hard drive and dragged the folders I wanted back over to my laptop.
But I'm in permissions **** though! When I want to copy them over I get an alert saying you may not have privilege to do this and asks for my password. I enter my password and it copies fine. But every time I want to do anything with those files (like move them, or delete them) I have to re enter a password.
So, inside of the terminal I do a "ls -al" command to see whats going on and find that everything is the same as a natively created folder except for a '@' on the permissions column. I do a "ls -al@' to see more details and I get this:
drwxr-xr-x@ 6 xenition staff 204 Jul 20 17:08 Assets
com.apple.metadata:_kTimeMachineNewestSnapshot 50
com.apple.metadata:_kTimeMachineOldestSnapshot 50
I did run repair permissions from Disk Utility and it didn't solve it. How can I resolve the permissions on these files?
Message was edited by: risingtiger

run ls -aleO on the copied files and see if there are any ACLs or flags.
BTW, another (and possibly better) way to restore files from an old TM drive is via TM interface. control-click on TM in the dock and choose "browse other TM disks" select a disk to browse and go at it. when you try to restore something you'll be prompted for a location to restore it to and maybe a password.

My external hard drive has "read only" permissions for me, how come?

i can see and move files FROM it to my MacBook Pro, but i cannot copy files back to my Seagate drive
its sharing and permissions are set to "You can only read"

How do I change permissions from read only on my external hard drive?

I'm a new convert from PC to MAC and I'm kicking myself because it's been **** ever since.
My music and business documents are all kept on an external hard drive and that hard drive is NTSF.
My MacBook is reading the whole drive as read only. I'm trying to add my huge library to the cloud but it's not reading it all.
How can I convert the drive to FAT without losing everything. I have 91 gigs of music that as a dance teacher, cannot afford to lose.
Please help!

If I'm only using Mac now, do I still follow #2 from above?
If you are going to use the external drive only with Macs now, you can consider the option to format the external drive with "Mac OS Extended (Journaled)". In this case, only Macs will read the external drive, but compatibility will be better.

If I go out and buy an external hard drive that's Mac compatible, will I still be able to transfer the files from my NTSF drive to the new Mac compatible drive or do I have to use a pc to solve this problem?
First of all, note that all external drives are compatible with Macs. If you find external drives which come as "for Macs", that's because they come formatted in "Mac OS Extended (Journaled)".
In that case, you will be able to transfer the files from the NTFS drive. Note that you can read NTFS drives and you can copy files from the NTFS drive to your Mac or other disks. The only thing you can't do is copy files to the NTFS drive

My external hard drive will no longer connect to my macbook pro via FW800........Any ideas on how to solve this??

Reset the SMC, see this Apple note: http://support.apple.com/kb/HT3964
Also reset the PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
In most cases, those two actions will fix the port issue. If it's still an issue, you may need to see if the external hard drive can connect to another system, to ensure it's not having problems.
