10.5.5 sets external volume to read-only

Bizarre.
I have 4 external volumes (2 FW800, 2 USB 2.0) and one of the volumes suddenly shifted to read-only status after updating to 10.5.5 this afternoon. At least, that's the error message I get when I try to touch a file anywhere on the volume.
Problem started when I tried to open iTunes and got the error message "The folder 'Music' is on a locked disk or you do not have write permissions for this folder." Get Info indicates that this user account does, in fact, have Read & Write permissions. Group and Other permissions are set to Read Only. Get Info does not allow me to select the lock to make changes, however, but nor is the "Locked" checkbox selected.
In Terminal, permissions for Volume "Little Brother" are indicated as:
drwxrwxr-x 11 <adminuser> staff 442 Aug 13 13:11 Little Brother
The Music folder in question appears to have the appropriate permissions as well:
drwxr-xr-x 14 <adminuser> staff 476 Sep 18 11:17 Music
Aside from the 10.5.5 update there have been no changes to the filesystem, and no files written to this drive.
I can touch files on each volume except for "Little Brother". Aside from chmodding the **** thing, does anyone have any recommendations for what I can do?
Thanks.

I think Ill just keep responding to this, every time Apple issues an update (patch) that causes the problem to resurface. I have contacted tech support. And they tell me they no nothing about this and have never heard about it. Then I tell them to check my support records. The issue is well documented there and goes back for many, many months.
So, today I came home to find that apparently my software update utility (which is set to NOT update the software) has updated my software. My brand new Western Digital external 2TB disk is off line and my Time Machine drive (1.5TB Maxtor) now appears to be completely after being kicked from the USB ever friggin time there is a software patch.
I'm trying one last time to recover following the procedure above - but once again I am running the procedure above against my 2TB user disk - so hopefully in 8 or 12 hours Ill know something. Thanks again to all the Windows developers who are now obviously working at Apple.

Time Machine backup fails w/error: Backup Volume is Read Only

This is another Leopard Bug! My Time Machine has always "just worked," but tonight, backup failed. Looking at the error message, it says, "Backup Volume is Read Only." My Time Machine was set up correctly, and has been working fine for quite some time. Now what?

Update: The next scheduled backup succeeded. I didn't change anything. Doesn't exactly give you that feeling of confidence in your equipment. The whole point of Time Machine is it is supposed to work in the background. If I have to think about it, and check up on it, it is useless, and I may as well return to my old manual backup methods.

I have an iMac(mid2010) running Pages v5.5.1 on OS X 10.10. Why can I not save or share documents. The error message is You can't save the file "TEST.pages" because the volume is read only.

I get the same message when using Numbers so I presume it is a OS problem

Some of your user files (not system files) have incorrect permissions or are locked. This procedure will unlock those files and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Back up all data before proceeding.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button
Select
 ▹ Restart
from the menu bar.

Time Machine reported 'volume is read only' & rolled back to old state

I've been in love with Time Machine ever since Leopard arrived. This has all come crashing down over the last few days...
Firstly I got a new 1tb drive, so I mirrored my old TM drive (using SuperDuper), and all seemed to be fine – backups were chugging along for a week or so as normal on the new, bigger drive.
A few days ago I got a time machine error stating that "The backup volume is read only". I thought this was strange as the drive was working without issue for a week. I checked permissions, format, etc and all were set correctly. I restarted and Time Machine kicked back in and all seemed to work fine other the fact that there seemed to be no backups created for 6 hours before I got the error message. Then I made a scary realisation, somehow the files on my computer had been restored to a state from 6 hours prior, all the work I'd done for the morning was gone.
I put this down to a one off glitch (stupid, stupid, stupid). I've today got the same "backup volume is read only" message again, and this time around my files have been restored to a state from 3 days ago. Fortunately this time around Time Machine has a backup of the important stuff a few hours ago.
I am now very worried about using the same disk with Time Machine. I also have no idea if Time Machine is the culprit (but logic tells me with the rolling back of files it must be). What should I do? How can I figure out what is going on?

This may fix the "read only" problem:
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.

External hard drive read-only?

Just got a Macbook Pro last week and I have found that my external drive is read-only, where it used to work perfectly on my old Windows laptop.
I can assume that the drive is formatted as NTFS from reading other posts, and that I must format it as FAT32 (I believe), but in the Disc Utility I do not see this option.
Can someone aid with this slight problem? I seem to be heading in the right direction as I'm not too keen on using third-party applications to enable writing.
Additionally, sometimes the drive will not connect (light stays red) but I assume that this is possibly related to the formatting issue at hand. Any suggestions?
Thanks in advance

It is FAT32. For some reason, OS X refers to it just as "FAT".
As AussieDJ indicated, you can use NTFS 3G. This allows your Mac to write to NTFS formatted drives. I personally have used this for quite a while and have never had issues. I have seen some posts from people saying it can be problematic. As I have never had a problem, I can't say specifically what issues might arise. Apple does offer it directly on their download pages:

External Hard Drive Read-Only Issue

I have a Samsung M3 portable 2TB hard drive which i used to back up my iMac to take travelling with my Macbook Pro. Today it has turned to read only and everything in the disk utility is greyed out. I haven't used this hard drive on any other machines. I've tried running this in Terminal as advised by KAPPY and here are the results:
sudo chown root:admin
chown: /Volumes/SAMSUNG: Read-only file system
sudo chmod a+rwx
chmod: Unable to change file mode on /Volumes/SAMSUNG: Read-only file system
killall Finder
When opening get info it says 'you can only read' in the sharing & permissions section. This is the first time i've tried to copy anything from the Macbook to the Samsung device since transferring all the data. Also sometimes when I connect the drive it doesn't appear in the sidebar in Finder. Macbook Pro with Retina display running OS X Yosemite v10.10.2.

I have found a solution!
http://www.cnet.com/au/news/how-to-manually-enable-ntfs-read-and-write-in-os-x/
"First ensure that your NTFS drive has a simple single-word name, and then go to the Applications > Utilities folder and launch the Terminal program. In here, run the following command to edit the fstab file (supply your password when prompted):
sudo nano /etc/fstab
The Terminal should now show an editor window for the fstab file, in which you can enter the following all on one line. Be sure to change the word NAME to the name of your drive (it is case-sensitive):
LABEL=NAME none ntfs rw,auto,nobrowse
When finished, press Control-O to save the file, followed by Control-X to exit, and then unmount your NTFS drive and attach it again. When you do so, the system will no longer immediately show it in the Finder, but you can go back to the Terminal and run the following command to reveal it in the hidden Volumes directory where the system mounts all attached drives:
open /Volumes
In the folder that opens, you should see the mounted NTFS volume, and should now be able to copy files to it, or otherwise manage files on it. If you need to access this volume more frequently, you can drag it to the sidebar, or make an alias of it in the location of your choice. You can also view the Volumes directory in Column mode to reveal it as a parent directory, from which you can create an alias instead of doing so on a per-drive basis."
This may only be a temporary fix but hopefully it will last me until I can afford to buy a new drive!

The back up volume is read only?

Can anyone help me with this? When time machine tries to run a back-up I get two errors and it fails. The first says:
Time Machine Error
The back up volume is read only.
The second one says:
Disk Repair
The disk was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible.

Error Backup volume is read only

Time machine is giving me an error message of backup volume is read only.
I am using a time capsule for the backup disk
How do I change from read only to read and write?

I erased my TC and started over. It seemed to work fine until I tried to see my backups, it crashed. I've switched to Déjà Vu: http://propagandaprod.com/
I've been using this back up software for years with out ever having problems, I switched to Time Machine because I liked the fact that you could replace one pictures from iPhoto or one Address instead of the hole library. But I can't risk my work, I was never a fan of using Disk Images as backup, they get corrupted to often. Déjà Vu Works perfect with TC so I'm going back to Old Reliable. Plus it doesn't hog up your Hard Drive space. It could Mirror your files, it has a safety net option where you could pick how many days to save, and it only backs up once a Day, Week or month. Which is better than every hour.

[SOLVED] Truecrypt mounts vfat volume as read only

Hey there...
After the recent upgrade to linux 3.0.6-2 truecrypt mounts VFAT volumes as read-only. The file that I usually mount is in a USB which is formated as NTFS (I can copy and delete files from the USB). I think is a problem with the vfat filesystem but I'm not sure.
Any help?
Best

I apologize because of this post... The problem was in the file (something was wrong with the container)... so the solution was to do a new volume and copy all the files to the new file.
Best,

Each class normally does have a method "FREE" named "Destroy"
Normally it should be enough to clear the object reference.
if it's still not working, try to copy your report and eliminate all stuff that has nothing to do with this problem. if you do not find the error then, pls post this coding.

What to do about Backup failed with error: The target volume is read-only

This is a weird story. My wife has a PowerBook G4/1.33 GHz that she uses in clamshell mode with a 20" Cinema Display. One day under OS X 10.5.6, her Time Machine backups (to a networked 500 GB Time Capsule) failed with the error: Backup failed with error: The target volume is read-only. So I upgraded her to 10.5.7 and erased the sparseimage file, starting a new Time Machine backup. And it just happened again. Any idea how this sort of problem arises? My wife was doing something at her computer when the Time Machine error occurred.
Please don't advise us to upgrade to 10.5.8, because her PowerBook freezes not infrequently with any OS later than 10.5.6, and I was just about to downgrade her from 10.5.7 to 10.5.6.

Try repairing the sparse bundle, per #A5 of the Time Machine - Troubleshooting *User Tip,* also at the top of this forum.
I've tried this before, but it can't be repaired, because it can't be mounted.

One possibility is, the HD in the Time Capsule is beginning to fail (all HDs fail, sooner or later).
I'm backing up to my own sparseimage bundle just fine.

Those two things may be related. Whatever's going wrong may very well be what's corrupting the backups.
I'd recommend finding out what's wrong with the Powerbook. It's impossible to tell, of course, but that may be the root of the problem.
There's a problem with PowerBooks and Cinema Displays. I've posted a lot about this. Even after a motherboard replacement, my PowerBook G4/1.67 GHz had freezes, and eventually Apple gave me a MacBook Pro, but I think there's a failure involving hardware/software design.
If you haven't yet, I'd start by dong a +*Verify Disk+* on it's internal HD (also per #A5);
That checks out fine.
if there are no errors, or they're fixed and the problem continues, run the +Apple Hardware Test+ from the disc that came with the Mac. (One of the discs should have that, and instructions for running it, printed in tiny type on the label).
If still no help, I'd be inclined to do an +Archive & Install, preserving users & settings,+ of Leopard, then download & install the appropriate "combo" update. That's a combination (thus the clever name) of all the updates to Leopard since it was first released, so installing it should fix anything that's gone wrong since then, such as with one of the normal "point" updates. Info and download available at: http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate (change the last "8" to the desired number). Be sure to do a +Repair Permissions+ via Disk Utility (in your Applications/Utilities folder) afterwards.
