Help, MBP Hard Drive is Read-Only, Can't access or unlock any user preferences

I could really use some help. I have searched and tried what I could but I am at a loss with what to do. I first noticed this last night when I was trying to switch users and after entering the correct password nothing would happen. I then went to Preferences to reset my password and the lock icon was closed so I clicked to unlock it and it prompted me for my password and after entering the correct one nothing happens. It simply reverts back to the same window without unlocking.
I am unable to switch users, unlock any locked preferences, install any software, etc as anything that requires my admin password won't work. I am entering the correct password because if the wrong one is entered it "shakes" and the correct one looks as if it will be accepted but it doesn't.
I have tried running repair in Disk Utility and rebooting multiple times to no avail. I finally decided to try and reinstall Lion however once I get to the page asking for admin allowance it again won't go past the password screen so I can't even do that.
After reading tons of threads I came across one that pointed to my Macintosh HD. I chose get info and it turns out that I am now Read Only. The only one with write access is System. Therefore I can't do anything.
I am completely at a loss and really need some help. Some threads I've come across mention running scripts in Terminal but I have no idea what is actually relevant for me and would really prefer some specific help. I was on 10.7.1 so I upgraded to 10.7.2 but the issue is still very much present.
Any help is greatly appreciated. Thanks.

Reboot and hold down the option key at the startup chime. Select Recovery HD. Launch Disk Utility. Try repairing permissions. You can also reinstall from there if you wish.
What have you been using to make backups? Time Machine or some other program?

External Hard Drive Becomes Read Only

I have a LaCie Hard Drive that Time Machine has been backing up to for about 4 days now. All of a sudden, the external hard drive is read only. When I go into Get Info for the hard drive, I can't even change the read/write permissions - it's all grayed out. This is the second time it's happened. The first time was on a Western Digital MyBook. TM fried that drive. At least this drive hasn't disappeared like the last time.
I've now changed the Time Machine backup to my second hard drive on my Mac Pro (which is screaming along, as opposed to the FW800 [!!] backup on my La Cie, whose file transfers are slo-o-o-w).
The idea behind backing up onto the external was so that if I ever needed to leave during a fire or earthquake, I could bring this with me and not worry if my computer was destroyed. Insurance would replace the computer, and I could replace my system.
If it weren't formatted properly, it wouldn't have been backing up for the last few days.
Can anyone help?

Thank you to everyone who has posted about this issue -- it just happened to me AGAIN this morning (this is my 3rd time), after I installed the 10.5.2 update. The first two times were right after I hooked up my external Iomega 500GB drive to use with Time Machine and I thought it was something I was doing. Then it seemed to work fine for a couple months so I thought the problem was over. Guess not! It is frustrating because I just lost about 2 months worth of backups. So finally I searched Apple's discussion forums and saw that I am not alone. However, no one was really posting a solution other than to say "reformat the drive".
So I did a Google search about this topic and encountered the following article. I have just gone through the steps he outlines and although I won't know for awhile if it works, I figure at this point it can't hurt to try. I hope this proves useful to others as well. (One note -- in his article, he says to skip the Erase tab and go right to the Partition tab. If you don't see the Partition tab, first erase your corrupt Time Machine backup disk and then follow his steps.)

My external hard drive is read only

Hey guys,
I'm just transferring stuff from a windows pc and i had all my music on my external hard drive. Well i set my default iTunes folder back to my external on my new mac but my hard drive is read only so it won't let me download anything after i buy it. How can i change it from read only?
Thanks

If the external drive is formatted NTFS, OSX can read but not write to it.
MacFUSE is supposed to add NTFS write support to OSX
<http://julipedia.blogspot.com/2007/03/ntfs-readwrite-support-for-mac-os-x.html> , but it may be safer to copy the data from the drive, the re-format it to Mac Extended (or FAT32 if you still want to use in on Windows). Re-formatting will erase the disk, so save the data first.

I lost my images from my hard drive and now I can not access them in Lightroom. What can I do?

I lost my images from my hard drive and now I can not access them in Lightroom. What can I do?

Your images are truly no longer present on the hard drive(s)? Have you had your operating system do a search for them?
If such a search fails to find them, here's what I would do, in order
Look in the trash can/recycle bin
Restore from backups
If you don't have backups ... well, why not? ... find a program on the internet called an "undelete utility" (free versons are available) and then download and install it and run it. If you are going to do this, then do not perform any other tasks on your computer except find the program, download it (if possible to a different drive than the photos were stored on), install it (if possible to a different drive than the photos were stored on), and run it. In the future, you will need to commit to making regular backups of your photos and of your Lightroom catalog file, no excuses.
If that doesn't work, but the thumbnails still appear in Lightroom, you can probably recover the thumbnails from Lightroom via a plug-in, but these would be low-resolution versions of your photos, if you really need instructions on this step, write back

Time Machine once worked, now external hard drive is "read only"

I have a 2005 iMac G5, running OS X 10.5. Had some power issues, and reinstalled (and archived) my OS a couple of time.
Recently purchased Western Digital 1TB external hard drive for back up. It worked once or twice, but now shows "read only" status.
Disk Utility won't do anything, because it's read only (can't repair, erase, partition or convert).
Hard drive works on PC running Windows 7, and newer Mac with Snow Leopard, just not the one computer I need it for. Any suggestions?

This may help:
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.

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.

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

1 TB Seagate hard drive, USB connected
i can see and move files FROM it to my MacBook Pro, but i cannot copy files back to my Seagate drive

External hard drive becomes "read only" and won't let Time Machine back up

I have an external hard drive for back up, and it has been working fine until recently.
There is a version of 10.6.6 loaded on it also.
The back up will fail every few days. When I do some checking, the back up drive is "read only" but I am not able to switch it to read/write. I cannot repair it with Disk Utility as the repair buttons are grayed out.
I can run DiskWarrior and it will fix it, but it runs super slow and takes all the memory to do it. I can barely use my e mail while it's running.
Anyone know what's going on?

System log says:
3/27/11 8:01:19 AM com.apple.backupd-auto[1559] Not starting scheduled Time Machine backup - time machine destination not resolvable.
It's read only because:
A: I cannot do repairs under Disk Utility, the buttons are grayed out.
B: I right click and "Get Info" and if I click on the lock icon, nothing happens.
C: The disk is not listed in the Time Machine backups.
I will try to take better notes the next time it happens and give you the exact messages.
There is another drive daisy chained to this external drive which holds my music. The music drive does not have a Mac OS installed on it and is only for storage. It works properly.

NTFS External Hard Drive now read only

Hello Everyone,
For months I have been connecting a NTFS 1 TB Phantom Labs external hard drive to my mac book, to access my music collection, as well as store additional large files. Today, however, I found my external hard drive to be "read only," rather than read and write. Interestingly, the folder where I keep my music, also includes the lock image as the external hard drive icon.
When I look in Disk Utility, the Phantom Drive is originally listed as read/write. However, the mounting point, named disk2s1 is listed as read only.
Does anyone have any idea how to resolve this situation and return to the read/write status I originally enjoyed?
Thanks.

I have got the exact same problem!!
have a 320 seagate ext HD formatted as NTFS that I have been using for the last 3-4 months that suddenly became read only.
I'm running macfuse with 3G to read and write to the drive and prior to this have never had an issue.
Have another ext HD formatted as NTFS that reads and writes fine. I have tried disk utility but verify and first aid are greyed out for the seagate drive, One minute I was writing to my drive fine and next time I plugged it in Read only (yes I ejected properly as always)
Any ideas?? I hope it's not a re format and start again..

Error says my External backup hard drive is read only

I have a WD External drive that I use for my Time Machine backup. I turned on the computer today and it says it cannot backup because the drive is read only. It appears on the desktop and in the Finder window. When I open Time Machine preferences, it's identified as the backup disk. But when I choose "backup now", I get that message (it's read only).
Do I have to partition this again using Disk Utility or is there a simpler solution? Thank you,

[Solved] Laptop Suspend puts Hard Drive into Read-Only

My problem is that s2ram brings back X (and the virtual console, if I'm on one), but never the hard drive.
s2ram -f -a 1 suspends just like s2ram -f. -a 2 and 3 just make a high pitched sound.
I tried both http://wiki.archlinux.org/index.php/Suspend_to_RAM and http://wiki.archlinux.org/index.php/Pm-utils methods.
I updated my BIOS drivers but that didn't help

I need a step-by-step plan: my WD external hard drive is 'read only'

Hi,
I hope someone can help me, because i'm in quite a pickle. I bought a WD 500 GB external hard drive a couple of months ago. I have a MacBook Pro version OS X 10.8.5. The problem I have now is that I haven't used my external hard drive for a couple of weeks now, until today (note: I bought this hard drive and used it for the first time on my macbook pro, never on windows before or any other laptop/pc), and all of a sudden I can only 'read' my hard drive, it suddenly seemed to have changed it settings by itself to 'you can read only' whilst I never did anything to the permission settings....
So i read a couple of questions about this online, and apparently im not the only one with this problem. but all the answers i read are way too complicated for me, with too much computer jargon. Therefore i just need a simple step-by-step answer, whatever i need to install or 'configure' in order to make this thing work again!!
Please can somebody help me??? I never used this thing for more than a month and only my macbook pro....help!! It cant be that i used this hard drive once and then all of a sudden it changes it's settings??
Thanks,
Daphne

If you can see the hard drive in Finder, select it, do a Get Info (command - I) and see what permissions you have in Sharing and Permissions. It should be Read/Write. If it isn't, unlock the padlock, and change it. Then look towards the top to see how the drive is formatted. It normally should be Mac OS Extended (Journaled).
If it is not that format, go to Applications/Utilities/Disk Utility. Open Disk Utility select the drive, select the erase partition, and after making sure the correct format is set, erase the drive. At the bottom the current format is shown. This will remove anything that was on the drive.

External Hard Drive is read only?? how do i change this?

ive just gotten a new external hard drive which i use a giant usb pretty much,
only problem is when i drag files into it to copy it tells me that "untitled" cant be modified.. also when i check its info im told that it is read only... how do figure out how to change this...
i need help please

Hi jami01
You need to reformat your new external drive in Disk Utility. Currently it will be formatted as NTFS which is a windows format and the Mac can read that but not write to it, hence your problems.
If you wish to use it solely with your Mac and not share it with a PC, then then choose the HFS+ format
Open Disk Utility,
-Select the external disk in the left panel. make sure you have selected the correct disk.
-Click the Erase tab
-Give the disk a name
-Select the Volume Format type to be HFS+
-Click Erase
If you wish to share it with a PC then Choose MS-DOS(FAT32) format

[SOLVED] Strange Hard Drive Errors - Read Only Filesystem?

Solution: Discard old laptop, buy new laptop
I have an Acer Aspire 5103WLMi. For about 2 months now, Arch has been running smoothly. Until 2 weeks ago.
It all started when I tried to install and configure autofs on Arch x86_64. On the next reboot, all manner of errors were printed to the screen, to the effect that the internal hard drive was only being mounted read-only, rendering the system unusable. I tried to find a solution, but there were no references to read-only anywhere; fstab, grub etc. None that I could find.
I tried reinstalling. However, x86_64 Arch refused to boot properly first time due to the exact same error; and I *know* that I'm configuring everything correctly. I managed (somehow) to coerce i686 Arch to install, and things "work".
Seemingly out of the blue, during normal operation, all running applications will stop, and spit out error after error to the effect of "Cannot Write to Read Only Filesystem!". Sakura won't load (Input/Output error, apparently), and the only way to shut down the laptop is a hard reset (I can't log in as root or use sudo because it wants to write to the filesystem first, which it obviously can't.
Now, I'm going to be giving the insides of this laptop a good cleanout this weekend, and I'm in the process of backing up all of my data, but I was wondering if anyone else has come across a similar form of misbehaviour; or (with a bit of luck) some potential solutions?
This is very peculiar, because there seems to be no reason why the laptop suddenly loses write permissions to the hard drive. Cheers.
Edit: I think I should point out that my /boot partition is Ext2, and / and /home are Ext3

Everything being either Old_age or Pre-fail is not encouraging. Additionally, in the output is what I believe to be records of what caused my strange read-only behaviour:
Error 19 occurred at disk power-on lifetime: 3287 hours (136 days + 23 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
ER ST SC SN CL CH DH
84 51 01 11 18 6a e1 Error: ICRC, ABRT 1 sectors at LBA = 0x016a1811 = 23730193
Commands leading to the command that caused the error were:
CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name
c8 00 48 c4 17 6a e1 00 04:43:08.023 READ DMA

c8 00 20 5c e5 69 e1 00 04:43:08.009 READ DMA
Could this truly be referring to my problem, since the 'logs' show that the *exact same* error occurred many times.
Not that this tells me how to fix it...
Well, if anyone knows if there is a solution, I'd love to know. If the only solution is to ditch the Hard Drive, fair enough. Either way: I'm backing up all of my important data ASAP.
Cheers.
Oh, and kclive18, after I noticed that I couldn't get onto my Drive, I reinstalled arch, leaving no trace of /etc/autofs/auto.media.
Additionally, somehow I have now been able to install Arch x86_64, but the problems still occur...

External Hard Drive Is "Read Only"

Hi,
I'm currently running OSx Lion on my MacBook Pro and I recently wanted to use my external hard drive to transfer some files from my Mac to my PC. The problem is, after plugging my exxternal into my Mac, I noticed I only have the ability to "read" the files on the external. The external hard drive is a Maxtor OneTouch 4 and it is a Windows NT File System (NTFS).
When I do "command+I" and go to "Sharing & Permisions" it just says "you can only read". There are no other options, no padlock icons... Nothing.
Is there any way I can fix this? If so, can it be put simply (I am still struggling to use a Mac, as you can see, haha).
Thanks in advance!

Mac will not write to a NTFS volume. There are third-party apps out there which can fix that, but I've no idea if they'll work with Lion.
If you need to transfer files between Mac and PC regularly, re-format the drive as FAT32 (or exFAT, aka FAT64, if the windows version supports it).
exFAT would be preferable if it's available as FAT32 has a file size limitation of 4GB.

Hard drive is read only now

My brother hooked my external hard drive to his computer and now that I plugged it back into mine, it is read only. How can I change it back? I need to access all of my info.

Without know what he did to screw up your drive we would only be guessing.
If you would post a screen shoot of the information pane for the drive that might give a clue as to what he did to you.
