A volume you are backing up is case-sensitive... but it's not

New mac Pro Quad core. Ran Time Machine for the first time on March 12th. Loved it. Used it several times to recover small files. May 31st was my last successful Backup. Since then I only get the "A volume you are backing up is case-sensitive, but the backup volume is not" error. I have three internal drives: main - HFS+, Time Machine - HFS+, and an NTFS Drive for windows/bootcamp (but that drive is excluded from the back up.) I run VMWare, but that didn't cause any problem early on. I do mount a server drive automatically, but can't exclude that, so presume it is not included. Can't see any problems in Disk utility. Any suggestions as to what to look for or do would be appreciated.

Use Disk Utility (in your Applications/Utilities folder) to look at each partition: the line(s) indented under each drive, showing the name shown on your desktop/Finder sidebar. Towards the bottom, the Format should be +Mac OS Exended (Journaled).+ If any are +Mac OS Extended case-sensitive (Journaled)+ or +Mac OS Extended case-sensitive,+ that's the culprit.
If they all show correctly, Click here to download the +Time Machine Buddy+ widget.
It shows the messages from your logs for one TM backup run at a time, in a small window. Copy and post the messages here (be sure to get them all, as sometimes they overflow the small window).

10.5.5 Update Now: A volume you are backing up is case-sensitive

Since the 10.5.5 patch, Time Machine will not backup. I get the following dialog:
A volume you are backing up is case-sensitive, but the backup volume is not.
To select a different backup volume, or to chose not to backup the case sensitive volume, open System Preferences and choose Time Machine.
Here is the problem. All my drives are formatted the same way including my backup drive.
Mac OS Extended (Journaled)
In fact, I can navigate through my older Time Machine backups (both in Finder and through the Time Machine UI) and see that previous to 10.5.5 backups were case sensitive. Or, at least they are showing proper case when I manually view the filenames.
A couple of days now without any backups has me very concerned about Time Machine. Thank goodness I have a Drobo as my primary storage.
Anyone have any recommendations?

Before I go on, I will say I'm not yelling at you - I'm venting in frustration. And, some of this is written tongue-in-cheek is it were, but perhaps you will get my meaning. All of it is factual.
I understand that much of Time Machine is smoke and mirrors until you are in the IT industry and understand what TM is doing. Trust me - it's not rocket science. Basically think of each file as your mailbox. When the file is altered, the operating system raises the mailbox flag to tell the postman (the backup application) "Hey - something is different here and this file needs to be copied". The backup application copies the modified file to a compressed file called an archive (or library) and then lowers the flag. The next time the backup application runs, it looks at all the files again to see if the archive bit (the flag) has been set (raised) and if it has ... you know the rest.
What is really frustrating is that we are growing more and more digitally dependent and we have no real reliable solution to data storage. It's not like I can send the drives back for warranty service, or even diagnostic - with all the digital information and continued identity theft. We were told that tapes were the solution, but they never work. Then CD-ROMs and DVDs were the rage and they were suppose to last a hundred years (cough cough) I mean months, (cough cough) I mean ....
And now we have TM.
Secondly, because digital data grows exponentially every year (those digital cameras aren't producing smaller images - for example) you have to grow your storage. Now Mr. Consumer is looking at 1 and 2 TB storage solutions for the home. So we need reliable storage and reliable backup. For example, I use Apple Aperture and am an amateur photographer. On my desk currently is nearly 6TB of storage. Now that may sound like a lot but I assure you it isn't. One disk is 1.5TB and is used to backup my 2TB primary disk (931GB used). A third disk was purchased as an emergency 3 weeks ago when the 2TB disk started to fail. Following instructions on Apples site, I used the DITTO command to transfer files from the original primary storage to the new storage. Unfortunately, the new storage unit had to be placed on a USB 1.0 chain. The transfer took WEEKS, yes WEEKS to complete and even then failed to apply proper user and group ownership. Just when I was about to try and clone the disk again, the latest patch came out and kicked two of the drives off the USB and placed the third into read only mode. Just like it does every time. And yes, I have turned auto update OFF and no, no one at Apple can tell my why it is automatically applying updates. They swear they are not doing a silent push.
As to the MS Windows approach of telling a user to "reinstall" their system frequently to resolve such problems - that is simply asshattery at the highest level. As an MCSE it is that kind of resolution which shifts the problem from the vendor to the client that I found unacceptable and why I moved from MS to Apple in the first place.
If I were to tell any of my customers that I'd quickly be without employment! We need to put pressure back on vendors to provide reliable solutions. I should not be expected to run verify and repair on each of my disks every time Apple comes out with a patch for some minor applications - which is what is happening.
Such actions (against TB drives) take hours to run and it's just plain unacceptable.
Luckily for me I use Drobo as my primary storage device. If it wasn't for Drobo - I would have lost all my data long ago. Through all of this, Drobo has continued to be (pretty) rock solid, despite the fact that I have to verify the volume every time there is a software patch and it takes all night. Oh, and by the way - before any of you run out and buy a Drobo for your users files (which I highly recommend) you should know that the folks over at Apple state that "the operating system does not support relocation of Users home directories" - which flies in the face of UNIX design.
In fact, the tech support rep who told me that directed me to relocate all my user files (all 931.45GB of them) back to the 150GB boot disk. I tried explaining to him that I had over 900GB of data, but he couldn't grasp that. I also explained that the reason my user directory was on an external drive was because some of the applications (when they were installed) required the files to be native in your home directory path, and my internal SATA disks were limted in size (apparently by architecture design) to 150GB. No one at Apple can explain this to me, the reasoning is also apparently quite a secret. But, I always understood that one of the reasons to migrate to SATA was that it reduced the need for the operating system to ... oh never-mind.
Now, I'm no math major but the last time I checked 931GB of data won't fit on a 150GB disk .... I could be wrong. If I am, I'm a big enough man to admit it so someone please explain it to me.
There, now that all of that is out of my system. I am truly a reasonable man. Please feel free to tell me why I'm wrong here or what I'm missing in the picture.

HT201250 error: a disk you are backing up is case sensitive, but the backup disk is not.

Time Machine error: a disk you are backing up is case sensitive, but the backup disk is not.
How do I reformat my backup drive to backup a case sensitive hard drive?

See here, for example. Do not select MS-DOS, but use the default "Mac OS Extended".

HT3275 Time Machine couldn't complete the backup to "My Passport Studio".. A disk you are backing up is case-sensitive, but the backup disk is not.

Hi,
Time Machine won't back up files on another external hard drive as it says it is case sensitive. The other drive contains mainly music and pictures.
Thanks for any suggestions,
Lisa

You are opening for the first time, but I'm not

Recently I have been getting this message sporadically with some applications after a restart. Parallels even asks to be re activated sometimes. Also, more often than not after a restart my Safari home page has defaulted back to the apple web site.
I have done a complete reinstall of the OS from the retail SL disk and run the software updater. I have repaired permissions and verified the disk. Lastly I have dumped the com.apple.luanchservice.plst and cache.
Please... any other suggestions. Its a macbook pro.

OK, I can concede this point. You need to disable APE when you do an install or update.
I have gradually got used to the lack of Fruitmenu. For my workflow its main function is available on the sidebar. My objection to the sidebar is that it is on every open window and constitutes a waste of space.
HoudaSpot is an excellent remedy for the loss for the shortcut for find-by-file-name in ML.
Does anybody know of a way to replace the functionallity of WindowShade, which is the only OS9.2 feature I still find indispensible?????????????????????????????????
Apple's minimize function is inferior to Windows because the minimized items are tiny due to sharing dock space with all the other things you have in the dock. However, I think it unlikely that Apple will return the functionallity of the dock back to the Apple Menu and provide a Windows-esque minimization function. This is why WindowShade is an actual requirement on an Apple OS, not just a mere whim.

How do i get my contacts back? they are backed up by i cloud but when I "MERGE" only the new ones are there and not the old ones

how do i get my contacts back? they are backed up by i cloud but when I "MERGE" only the new ones are there and not the old ones

Hi sfuentes,
You need to check iCloud to see if they are actually there. Go to iCloud.com and sign in and then look at your Contacts there to see if the old ones are still showing on iCloud.
If they are not, then you can either re-enter them while you are on iCloud.com, or you can restore your device from the backup where you saved them:

I want to install an old airport express, the ones which are directly plugged into the socket - but it does not work with Maverick or Snow Leopard - can I configure it with a windows pc?

The Mac running Snow Leopard should be able to configure virtually any version of the AirPort Express.
Tell us what steps that you are taking to configure the Express and what happens after each step.

I have the kindle app on my I pad. How do I eliminate books I've already read? On a regular kindle, you can switch between cloud and device but I am not getting that option. Thanks

I have the Kindle app on my I pad
I want to eliminate the books I've already read (I have a LOT).
On the regular kindle you can switch between cloud and device but that is not working on my I pad.
HELP.
Thanks

The Kindle app has a menu on the very bottom center of the screen that allows you to switch from a device and cloud view. To remove a title from the device, tap and hold on it. a pop menu will apear that allows to add the title to a collection, remove it from the device, or download it from the cloud (depending on its current status).

Cannot install. Main volume is case-sensitive, but I have a volume that is not. How do I change the installation volume? Creative cloud does not support case-sensitive volumes.

I cannot install creative cloud on my macs main volume which is a case-sensitive volume. I have a second volume that is not case sensitive. How can I get the installer to use that volume?

YOu can't. The CC app itself will always install on the system volume. short of reformatting your volume there is no way to resolve this.

I'm deleting old back ups in time machine but it's not freeing up any space

Time machine cannot back up because it is full and is not deleting old backups.
So I delete back ups myself and it doesn't fire up any space!

The problem is that the backups of the old computer are still on the volume, and Time Machine won't delete them to make room for more backups of the new one.
At the top level of the folder Backups.backupdb, there should be a subfolder with the name of each computer that has ever been backed up to that volume. Delete the one with the name of the old computer by dragging it to the Trash and emptying. I warn you, though, that sometimes the Trash will fail to empty, and then you'll probably have to erase the volume and start over. Do this only if you have at least one other complete backup of all current data (which you should have anyway.)

I lost a lot of tracks while syncing my ipod touch with iTunes. I have managed to get some of them back with a free download, but iTunes will not let me dowload whole albums which I have paid for. It does recognise that they have been purchased. What do n

As I've already said to get this far: I have lost a lot of tracks while syncing my iPod Touch with iTunes. I have managed to get free downloads of some of the single tracks, but when I try to download entire albums the system informs me that I have already purchased them and a pop-up window informs me I can get them back from my "Purchased" file. I would not be trying to dowload them again if they were anywhere on the iPod, would I? The other problem seems to be that with single tracks I don't know before I hit the purchase button if I have picked it from the right album and I have had to pay for it again.
I feel that I have been totally ripped off by iTunes and, apart from ranting on this forum, I don't seem to be able to let my feelings known. It's like a guy from my local record store coming round and nicking my albums and telling me that it's tough!
The point here is folks, that it was syncing two Apple sites which caused the loss of these tracks and from what I've read elsewhere this is a regular fault. And please don't tell me that it's my fault for having a pc. Apple shouldn't sell a product for pc, when it doesn't work on pc!

- Are you saying that they are not listed in your Purchased section?
Downloading past purchases from the App Store, iBookstore, and iTunes Store
- Are they listed in your Puchases history when you log into your account on your computer?
- Are they still available now for purchase? If not then you are out of luck
If they are still available and listed in your Puchase History then contact iTunes
