Harddrive reverted to "read-only"

Hi, my external hardrive has reverted back to it's read-only form after a few weeks of running fine using tuxera so i can use my hardrive with my mac. Now tuxera or similar programs don't even recognise the drive- Can anyone help me?

That means OSX has already determined it can't fix it.
It's possible a heavy-duty 3rd-party disk repair app, such as DiskWarrior, can. These are expensive (DiskWarrior is about $100), and probably a good investment, but there's no guarantee it will work.
If you decide to do this, be sure to use only a version that's compatible with the version of OSX on your system.
If DW can't fix it, or you don't want to spend the money, about your only choice is to back up or copy off what you can, then try to reformat the drive. If you do that, take the time to click Security Options, then Fastest (Lion) or Zero Out Data (Snow Leopard or earlier). That will take quite a while, but if it fails, you know for sure the drive has failed. If it succeeds, the drive may be ok.
If all else fails, you might be able to recover some of the data, but it’s "iffy" and expensive. See Data Recovery.

External drive reverts to read-only on airport extreme

I have an external drive that works fine (full access read/write) when connected directly to my Macbook but reverts to read-only when I connect to it through my airport extreme. It also won't let me change the permisssions over the network. I have another drive used for Time Capsule connected to the Airport Extreme and it works fine, as well as the printer. The problem drive is formatted OS X extended (journaled).

What causes this to happen, and what can I do about this problem?
A number of things. Most common is probably a power loss; second is probably disconnecting without first ejecting.
It's not permissions; try running +*Repair Disk+* on them, per #A5 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum).

HT4796 why are all the files on my external harddrive showing as read only?

I have a harddrive (Seagate) that I have used with my PC to store files. When I plug it into my Mac, all the files are read only. How do I fix that?

Most likely, the drive is formatted NTFS, which OS X can only read natively.
If you don't want to reformat the disk into something you can use on both, try exFAT.
If you want to reformat it only for a Mac, use Mac OS Extended (Journaled).
Either way you'd have to move the files off the drive, format, then reload them
There are several programs which will allow you to write to NTFS, Paragon, Tuxera, and NTFS-3G (free).

External drive reverts to read-only on reboot

My 2TB firewire drive becomes a read-only drive after a computer reboot. From a cold start, drives boots to read-write. How do I fix this?

When a win7 users accesses a file on the server the permissions on the file revert to read only.

Hi there,
Originally my enviroment was 100% Mac, but now we have merged with another company who are all PC users.
The issue I'm having is when a Windows 7 client accesses a file on the Snow Leopard server the file becomes Read Only, and I have to manually propergate the permissions to fix it. This isn't an issue with XP users.
So far this is only happening with Excel files.
Is anyone else experiencing this issue? Any help would be greatly appreciated.
Cheers,
J

I'm having a similar issue as well. Excel 2007 appears to be the culprit, but hard for me to say. Running 10.6.8 here as well.

External harddrive limited to 'read only'

I have a hard drive that is set to 'read only' and is formatted as NTFS. How can I change this so that I can save files to the disk, without reformattin and losing everything on the drive?

Best is to connect that external to a Windows PC, Copy all the files off it then format it either FAT32 or exFAT on the Windows PC. That way both Windows and OS X can write and read from it.
3rd party software will work but can be problematic.

My external harddrive has switched to read only

i have a western digital 1 tb hard drive which is formated to fat 32.
everything was going perfect on it until one day i was copying the whole drive to an older hard drive to create a back up when it came to my attention that my current external harddrive had become read only.
it made no sense.

Select the drive on your Desktop and then Get Info (command+i) In the window that opens, down at the bottom, are the permissions.
Click the small padlock icon and enter your admin password then change the Privilege to Read & Write, if you're asked to apply the same setting to sub-folder say yes. When that's done close the window.

Received error message 213:11 upon installation of CS5.1 upgrade from CS2 in Windows 7, unable to change SLStore to read only as administrator as suggested elsewhere. SLSstore reverts to read-only after changing, applying and clicking OK. Same problem after reinstallation.

Time Machine appears to be "read only"

My Time Machine suddenly turned into a Read Only device.
"Files can't be copied onto the backup disk because it appears to be 'read only.'"
"you may need to repair or reformat the disk using Disk Utility. If the disk can't be repaired, you must use a different disk for backups. Open the TIme Machine Preferences to select a different backup disk."
My computer Hard Drive is still running fine. Can I save a backup of the TIME MACHINE backups and load them into a new Time Machine drive.

Why not first repair the drive using Disk Utility?
Open Disk Utility in the Utilities folder. After DU loads select the TM hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your TM volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU.
The problem of having a TM drive revert to read-only is not new. There is this past fix:
What to do if Time Machine reports you don't have permission
This was posted in the Apple Discussions by V.K. I have only modified it slightly to be more generic.
The problem seems to be that 10.5.6 changes permissions on a file so that even the root user doesn't have write peivileges. I have no idea why they did this. The workaround suggested in [an]other post will probably work, too, but i did something less drastic. Instead of deleting the file I changed permissions on it, and it worked just fine. An added benefit is that the permission change seems to stick, so you don't have to delete the file every time you change a drive.
[Open the Terminal application in your Utilities folder. At the prompt [enter] the following command:
sudo chmod 644 /volumes/"TM drive name"/.xxxxxxxxxxxx
The name of the file .xxxxxxxxxxxx is based on the MAC address of your computer and will be different for every computer. Put the name of the TM drive in the above and keep the quotes.
You'll have to enter your admin password (which you won't see) which is normal.
This was edited by Kappy just for cleanup.
Enable Finder to Show Invisible Files and Folders
Open the Terminal application in your Utilities folder. At the prompt enter or paste the following command line then press RETURN.
defaults write com.apple.finder AppleShowAllFiles TRUE
To turn off the display of invisible files and folders enter or paste the following command line and press RETURN.
defaults write com.apple.finder AppleShowAllFiles FALSE
Alternatively you can use one of the numerous third-party utilities such as TinkerTool or ShowHideInvisibleFiles - VersionTracker or MacUpdate.
Also, see User Tips for Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.

Firefox is already running. "Check access rights" - Read Only, revert back and selected automatically!

I Have follow the steps releated issue "Firefox is already running, but not responding. To open a new window, you must first close the existing Firefox process, or restart your system".
However, issue is solved for sometimes by following steps (1 & 2) but the issue created again. Regarding step 5, I cannot applied it, because when I uncheck "Read Only" it revert back again!!
Please advise.
Note:
We are running the Firefox through Citrix XenApp Presentation 4.5.
Thank you

Do you get that all the time or only if you close Firefox and want to restart Firefox?

Read Only Harddrive problem

I have a WD Elements Drive and just bought my first mac product! Mac Book Pro Retina. I transfered files from my friends mac onto the drive and now I want to work on it on my laptop but it says I can not write any files onto the disk. I tried to change the permissions to the drive and there are no options on the GET INFO screen to let me write to the drive. It says READ ONLY.
I have searched Apples support and all the options they suggest I CAN NOT DO! There is NO LOCK ICON and the disk utility options are greyed out. Please help so I can start work again.
Love being a new mac owner!

Do you have any WD software installed? WD drives are currently having issues on Mavericks
https://discussions.apple.com/thread/5475136?start=255&tstart=0
Also verify same on the WD boards
http://community.wd.com/t5/External-Drives-for-Mac/bd-p/passport_mac
What format is the drive in?
Verify the HD on another Mac if you can.
Congrats on the new Mac, great choice. The WD not so much. If you have an option to return the WD, you might consider same.
Did you install any WD software when you hooked the HD up? or downloaded same?

All new files and folders show up as READ ONLY

I am new to the iMac, and am having problems with files an folders. My account is an administrator's account, but when ever I create a new folder, or move a file into it, it shows up as READ ONLY. This is really annoying as I am moving hundreds of files from my PC to the iMac. How do I set things up so that new folders and files are not READ ONLY? Thanks!

How to remove "Read Only" attribute on folders

Hi
I am logged in with my User account which has full control over my folders.<o:p></o:p>
I have a folder that I tried to add modifications to, however i could not do so because the folder was classified as read only. I have full permissions to this folder. Previously the app that
uses this folder could write to it quite happily, but today it fails. <o:p></o:p>
The 'attributes' for the folder shows a solid square in the read-only box. If I 'un-box' the read-only and apply > ok, when I look at the attributes again the box is still checked.<o:p></o:p>
So my question is, if it's not (which it shouldn't be) some sort of protected Windows folder, and I have full permissions on the folder (supposedly), why does Windows not respect my wishes,
get out of the way, and let me set it to what I want it to be?<o:p></o:p>
I have tried the following methods to fix this issue, but none of them work:<o:p></o:p>
-Adjusting permissions and control, and changing security options<o:p></o:p>
-Using a third party application such as "clear read only" to remove the check on the box<o:p></o:p>
-Using the "attrib" function on the CMD prompt<o:p></o:p>
-Boot Scan for virus/malware that is affecting folder attributes<o:p></o:p>
-Running applications and CMD as administrator<o:p></o:p>
I have heard that if using a NTFS harddrive, then all folders will be automatically “Read Only” and that it is impossible to change that attribute. I find this hard to believe, as all folders
should have some way of being modified, regardless of what HDD I’m using. I obviously cannot change to FAT32, so how else can I get my folders to get rid of this ridiculous error!
<o:p>I have also noticed that this problem is very common amongst Windows users. If this problem has been around for a while, how is it possible that no solution has presented itself.
Regardless, we need a solution to it, because i can't do the things i need to while the Read Only attribute remains a constant on my folders. I thought it may be a virus, but my avast anti-virus did not pick up any infected areas when the scan was done. I
have searched the internet, and no "fix" has solved this issue. The only fix i have not found is a reg edit that could completely remove this read only attribute from all folders. Though i feel this is not neccesary, as i only need the attribute
to be removed from certain folders. Please kindly assist me with this issue, hopefully it will help many others too...</o:p>
Many thanks.

Have you taken ownership of the folder? Please first take ownership of the folder, then change the security options

If you have already did this, then run a scan with this tool,

or copy this folder to another location, test again.

Read Only Permissions Error

Hi Guys
I have a major problem with file saving permissions
Current setup:
- 5 imac (10.6)
- 1 mac book pro (10.6)
- mac xserver
- Direct attached Raid Array
Issue:
When user "A" creates new files and folders to the shared drive on the raid array it automatically defaults to read only for all other users, and any time they try to add/delete/create files or folders in the fold user "A" created they get a permissions error. Therefor everybody else cannot edit the files
E.g. user A and user B quite often work on documents together and when user A stores it in the folder user A created then user B can only read it
has anybody come across this error before?
also i have tried changing permissions in get info as it defaults to read only soon as i change it to read and write and close the get info box it reverts back to read only ( the permissions group in called everybody)
Any help would be much appreciated

You can try propagating the permissions on the root of the share, new files should inherit permissions from the parent folder, if that doesn't help, maybe try something with the umask
