Samsung 2TO disk drive when unexpectedly to read only

I have been using a Samsung 2TO hard disk connected directly on the firewire of my Mac (27" of late 2009) running under Snow Leopard and it has been running properly with read/write and delete capabilities. I migrated to Mavericks yesterday morning and could use the external drive as before.
This morning (16-10-14) came as a surprise that I could not write anything anymore on this disk. After a check (information), the Share and permissions indicate "Read only". The format also indicates NTFS. It also shows that my last update is of 15/10 2:54 PM. I have no access at all on the properties of this disk, cannot look to the owners, group etc...and cannot configure it at all, even with disk utilities. I attached some screenshots. It seems that the only remedy is to reformat the disk! Is this true? No other means to avoid me exporting more than 1.5 TO of data?

Install updated Tuxera NTFS, your problem will be solved. The software u were using till update is may not compatible with Mavericks. Try the software.

Bring it to an Apple store or AASP and have them check out the optical drive.

My disk drive will no longer read my disks being inserted how do i fix this?

Take it in for repair.

I purchased a IMac in Feb later I added a Seagate ext. hard drive. On April 29 I received an errors that the ext. Drive may be a read only and not backing up files. I'm unable to check disk permission or correct errors. Help would be appreciated.

Click on the hard drive on the desktop, then File > Get Info. What does it say about permissions? If this is just a data drive you may want to consider "ignore ownership on this volume".
Otherwise I can only say I have not been reading good things about Seagate drives recently. I have some of their rock-solid ones from about 10 years ago (still running well), but now...?

External hard drives suddenly changed to read only

Three of my external hard drives suddenly changed to read only. These hard drives have been working on my macbook pro for months. When I click on get info 'read only' shows up and there is no lock icon nor is there a window that shows name | permissions, also in disk utility the 'verify disk premissions', 'verify disk', 'repair disk', and 'repair disk premissions' buttons are ghosted and I can not select them. I have not made any changes to my computer and I have read many other posts and have not been able to find a solution.

About a hundred times with no luck. Some of my research is leading to Western Digital, there may be a problem with the drives' 'smartware' software. I've been using this drive for months and I never used the 'smartware', but I tried it anyway with no luck. I just remembered that four days ago I had this drive plugged this drive into an Iomega wireless storage device and it seemed to work fine. Now the wireless storage device can't find the drive at all. I just need to know if there is a way I can change the permissions back to read/write, otherwise I will have to buy another drive and transfer all the data to the new drive and re-formatt the wd drive.

I have an external hard drive but it is read only on my macbook.

I have an external hard drive but it is read only on my macbook. I have tried my friends which works on his macbook but this is also read only on mine. Do I need to change any settings?

Here's my lo-tech solution (if you have Parallels) to this frustrating problem:
Eject your hard drive.
Unplug (USB) your hard drive from the MAC .
Start Parallels.
When Windows has started, plug your drive back into the MAC.
You should get a little screen asking if you want the drive to be utilized by MAC or Windows. Select Windows.
Use Windows to copy your files over to the hard drive.
This is less than ideal and not a long-term solution, but I was afraid of attempting any reformatting since I have many files on my hard drive.
Just remember that Windows has to be running first, before you plug in your hard drive.

My external drive keeps setting to read only, why???

Periodically a 1TB external drive suddenly switches to read only and won't let me save edited documents to it any longer. It shows as read and write for my access but still won't accept written items. I'm curious as to why. It's getting a lot of files but still has significant space. Is this an address space issue? Has anyone else encountered this on their Mac?

The drive is malfunctioning.

[solved] External drive automatically mounted as read-only

Hi folks,
I have a strange issue with an external drive automatically mounted as read-only whenever I plug it to my laptop :
[sclarckone@archLaptop ~]$ mount
/dev/sdb1 on /run/media/sclarckone/dd type ntfs (ro,nosuid,nodev,relatime,uid=1000,gid=100,fmask=0177,dmask=077,nls=utf8,errors=continue,mft_zone_multiplier=1,uhelper=udisks2)
And I can't remount it as read-write :
[sclarckone@archLaptop ~]$ sudo mount -o remount,rw /dev/sdb1
mount: cannot remount /dev/sdb1 read-write, is write-protected
But of course, I'm able to mount it as read-write on other operating systems.
I have udisks and udisks2 installed on my system. I also belong to the storage group so I thought I could mount a filesystem as a normal user but I can't :
[sclarckone@archLaptop ~]$ mount /dev/sdb1 dd/
mount: only root can do that
I don't know whether it is relevant to this problem, but I have systemd and polkit installed as well... Does anybody has an idea of where the problem could come from ?
Thanks for your help !

Check out following file :
/usr/share/polkit-1/actions/org.freedesktop.udisks.policy
Look for mount a device and It should have configuration like :
<action id="org.freedesktop.udisks.filesystem-mount">
<description>Mount a device</description>
<description xml:lang="da">MontÃ©r en enhed</description>
<message>Authentication is required to mount the device</message>
<message xml:lang="da">Autorisering er pÃ¥krÃ¦vet for at montere et fil system</message>
<defaults>
<allow_any>no</allow_any>
<allow_inactive>no</allow_inactive>
<allow_active>yes</allow_active>
</defaults>
</action>

My External Seagate Hard drive just changed to read only

my External Seagate Hard drive just changed to read only on its own?
I went to get info and scrolled down to the Sharing and Permissions
But there is nothing there but a greyed out : You can only read
There are No boxes to check or uncheck, No options to change to read and write, No name of owner or ignore ownership box. NOTHING ELSE IS THERE
HELP!
I have recently upgraded to Mountain Lion and am having other problems as well

Click on the external HDD icon COMMAND+I. You should see a display such as this:
You should be logged on as the administrator. Click on the lock icon. It should open and allow you to make the required changes.
Ciao.

TS5376 For "The program can't start because MSVCR80.dll is missing from your computer", I followed the steps and there is no C:\Program Files\iTunes and look for .dll files..Also, after the update, I no longer show my disk drive when I load a CD.

After downloading the new Itunes update, my compter now shows error: "The program can't start because MSVCR80.dll is missing from your computer". I follwed the Apple fix / steps but it did not correct it. Also, after the update my disk drive is not recognized on my computer. If I load a CD, I cannot even access it.

See also Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes (similar to the advice above) and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies. E.g. TS2308: iTunes for Windows: Optical drive is no longer recognized, or "Disc burner or software not found" alert after install.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

External Hard Drive changed permissions to 'read only'

I have been searching everywhere for a solution to this with no luck, so I figured I would start my own post and see what comes of it.
Computer: iMac Intel 24" /3.0ghz/4gb ram/1TB WD hard drive
External Drive giving me issues: Western Digital 1.5TB (has been formatted for Mac)
I recently installed a new main hard drive into my iMac after the original one began to die. I have an external drive that I had been using for achiving files for a long time, with no issues at all. After I installed the new drive, it has suddently become 'ready only' - thus, I cannot write to the drive at all, but can pull information off of it.
When I go to 'Get Info' and down to the permissions section, it is completely 'greyed out' - I can't change or click anything. It reads:
sckenyon (me): read & write
staff: read & write
everyone: ready only
Which is normal, but given that I should have writing priveledges, shouldn't I be able to change those permissions? Or that I should have writing permissions since it shows that I should have them?
I have tried some commands in terminal under other discussions, but I just get a statement that says the volume is 'ready only'.
I have tried Verify Disk in Disk Utility - doesn't do anything, just tells me the disk is OK. I have no option to repair permissions - they are greyed out.
So, can anyone help me out here? I'm at a complete loss! I'm not a complete noob at this, but I am definitely not an expert. I'm capable of following terminal commands if that's what it takes, but I do not want to format the drive if I don't have to (it's already formatted for Mac, so I don't see why I should have to).
Thank you

The problem may be an erroneous flag for the volume of the external drive that puts it in read-only mode. When I had a similar problem, the following steps corrected it.
1. Open Disk Utility and Verify the Volume.
2. If the verification shows that the volume is OK. If so, run repair disk. If the verification does not shaw that the volume is OK, STOP. Copy the drive immediately to oanotehr drive before proceeding. Failure to do so can result in permanent data loss.
3. After the repair function completes, close Disk Utility and start Terminal. It is located in the System Utilities. Type in the following command:
sudo chflags nouchg /Volumes/[Volume Name]
For example, assume your external drives are named Mary X where X is a sequential Arabic numeral. The command line for one of those volumes will be "sudo chflags nouchg /Volumes/Mary\ X" where X is the drive number. You will be prompted for your administrator's password. Note that when you type in the password, it will not be echoed in the terminal window for security reasons . Press "Return"
If your experience is similar to mine, your external drive will no longer be in read-only mode. Hope this is helpful.

Seagate 500 GB external hard drive allowing me to "read only"

Hi Everyone -
Well, I'm a Mac greenhorn - so I'm still learning the ropes of this wonderful world of Macs - after living with PCs my whole life.
I have a 500 GB Segate Free Agent Drive - I have tons of files on the drive that I would like to go through and delete - but I am only able to "read only" in the permissions. I've followed the help menu's instructions to do everything from change the settings in the files permissions to "read & write" - but the option is not available. I've gone into the applications/utility to try and repair the drive - but so far no luck. When I look at the information for the Free Agent Drive the specs tell me: The format is for the Windows NT File System. I'm guessing this is part of the problem?
Long story short: I need to be able to access/ add&delete files to the external hard drive on my Mac and my laptop. Is this possible? My software was all pre-loaded at the Apple store so if anything regarding reloading software is needed - I'm going to be clueless on that too. I'm usually clueless anyway
If anyone has knowledge - I'd greatly appreciate a suggestion.
Thanks for reading guys!

Hello and Welcome to Apple Discussions.
Macs can only read NTFS drives at this time. You should reformat the drive to HFS+ ("Mac OS Extended" in Disk Utility) for sole use with a Mac; or to FAT32 ("MS-DOS" in Disk Utility) if you need to use it with a Windows laptop and iMac.

MY Hard Drive says_"YOU CAN READ ONLY" for the OWNERSHIP AND PERMISSSIONS!

I cannot add anything to my EXTERNAL (SimpleDrivePS) hard drive. When I try to copy something to it, it says "The item cannot be moved because SimpleDrivePS cannot be modified."
Upon control-clicking this external hard drive's icon, under "Get info" it says "You can read only" for it's "Ownership and Permissions."
I have used this hard drive with Windows-based computers, but not with this new Apple yet.
What do I need to do so that I can move or copy things to this external hard drive?
Also, is there a discussion room for just general questions? - There are many little things that I wonder how to do from time to time as I am trying to become accustomed with Apple, like shortcut key for desktop, or where is control panel or link to "my computer" or other shortcut keys - things like that.

Hi newsppler;
Since I have never had a disk that was formatted NTFS, I am not absolutely sure exactly how you can discover how it is formatted. I think if you look at the disk with Disk Utility that should tell you.
Yes. If you reformat you will lose everything that is currently on that disk.
To reformat open Disk Utility and then select the disk. You then click the partition tab. This will allow you to select what format you wish to use. I would suggest Mac OS Extended +

External OS X formatted drive keeps switching to Read Only

Since completing the upgrade to 10.7.2, my generic external eSATA drive case holding a Caviar Green drive decides randomly that it should be read only, despite having been formatted as OS X Journalled. Disk utiliy says that permissions have errors but I cannot repair them. It also says taht the drive is not journaled which it was set up to be.
Using Get Info shows system as Read & Write, wheel and everyone as Read Only. Unlocking with the admin id does not allow changes to be made to the Read Only settings and consequently my Carbon Copy Clone update fails every time as did the Super Duper method I was using previously.
The point of an extra backup is to keep it up to date, not to have to format the idiot thing every couple of days.
It happened again today and given the lack of any kind of solutions found with Google, I tried to add an authorized user. I clicked the plus sign and selected my own id. After accepting, the id was not added, nor was the Administrator group when I tried to add that. However for reasons I do not understand I was now able to change wheel and everyone to Read & Write. I was able to get CCC to do its update but I continue to have issues making the privilege correction stick.
Once I was able to filter out all the dreck about NTFS mounts, I discovered that A LOT of users were complaining about this happening and all the "helpful" advice was to reformat and start over. That's not particularly helpful as it does not fix the problem or prevent it from happening again.
I don't know if the workaround I discovered will work again and I suspect that since both Super Duper and CCC actually call the open source service called rsync, there may be a bug in rsync in OS X 10.7
Anyone know the root cause and the permanent fix?
Thanks!
Ross

More info. It's not RSYNC. My LaCIE USB3 drive that has worked flawlessly as a RW volume decided that it is Read-Only. My trick above does not work. What a pain in the butt this is, and no answers from Apple as to why this happens.

Can I show correctly formatted text areas when they are read only.

Hi all,
I have an application that allows users to enter large blocks of descriptive text in a TextArea field. This is a simple TextArea field with no spell check etc and is not an HTML editor.
As part of this entry I use the normal 'return' key to enter line breaks / new paragraphs as you would expect.
This works fine and the data is stored correctly. When I extract this text, via XML, into a BI Publisher PDF document, the text is correctly formatted with line breaks where they are expected.
However, when I try and display this information on the screen, in read only mode, the line breaks are lost and all I see is a continuos block of text with no line breaks.
I am displaying this as a TextArea in a read only form (basically the page is a copy of the entry/maintenance page with all the fields set to ReadOnly = Always) and I cannot get it to display correctly. As soon as I make the field ReadOnly = Never the text dispaly OK, but then the user can go and change it.
How can I get this field to display correctly?
Many thanks,
Martin

Hi Dimitri,
Thanks for your reply.
I tried changing the field source to:
select replace(replace(MANUAL_STEP_TEXT,CHR(10),'
'),CHR(13),'
from tpa_rel_patches
where patch_id = :P40_PATCH_ID
and now I get:
1.Take a backup of existing jdbc driver files In all the Tiers (Admin, External & Middle Tiers)
cd $JAVA_TOP
cp jdbc111.zip jdbc111.zip_4899697
cp jdbc12.zip jdbc12.zip_4899697
cp jdbc14.zip jdbc14.zip_4899697
2.Apply the Oracle JDBC Drivers Patch using ADPATCH
u4899697.drv
Any ideas?
