Mac OS Disk Format, claiming to be Case-Sensitive on a NonSensitive system.

I recentely swapped out drives on my 2009 Mac Mini. And for some reason, even though i specifically formated it to be a non-Case Sensitive drive, it still claims it is. I'm currently trying to load steam and it says that my drive is case sensitive. Can anyone help? My boot/main drive is formatted as Mac OS Extended (Journaled) PLEASE HELP!

You need to prep the drive as follows:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Time Machine automatically formats new external drive CASE-SENSITIVE?

I noticed a strange thing when I set up Time Machine. I'd bought an external drive that was presumably pre-formatted as FAT32 or NTFS, so when I connected it and told Time Machine to use that drive, it told me it needed to format the drive, so I told it to go ahead.
It happened so fast that I wanted to make sure it had worked, so I checked the stats on the drive, and I noticed that it was formatted "Mac OS Extended (Journaled, Case-sensitive)". I thought it was a bit odd that it was formatted case-sensitive. When I google for this, the only thing I find is people saying that the external drive should NOT be case-sensitive.
So what's going on here? Should it be case-sensitive? Is this a glitch? Should I be concerned? Should those who don't use case-sensitive be concerned?
Thanks!

Well, I've been reading through some other discussions in this forum, and some people have attributed problems with Time Machine to the disk being formatted case-sensitive. So the issue is still up in the air. So far, I've only done an initial backup, and that worked fine. I've also read about people having trouble with subsequent backups. Also, some people report that Apple's tech support instructions specify that you format the drive explicitly without case-sensitivity. There are inconsistencies here, and Apple is mum about the details. So this kinda leaves this up in the air.
BTW, you say the drive will only be used for TM. Is that necessarily the case? I mean, can't I use it to store other files? I got a 500GB disk because it was on sale (a My Book for $125), and I figure it'll take a while to fill up, so why not use the disk for other things?

I recent la format the drive and create a case sensitive jornal and put a password. How I undo it if I just see the whole drive as the recovery disk

I want to format my computer and I start to do that but I fondo a copy of the boot folder on the drive, not the recovery drive. I formated and make it case sensitive jornal with a password. Then I put a password in main too. So the drive the entre drive become my recovery drive.So I have two recovery drive I think.I learn almost all the diskutil comando and I don know how to fin it. The disks are not showing the one with the passwords.

Hi Kappy,
Just wondering if you had any advice for my situation . . .
My time machine backup was backing up to a drive that was "Mac OS X Enteded Journaled, Case Sensitive." I had no idea what this meant, or that it would even cause issues.
I took my computer to the Apple store yesterday, and they wiped it clean. When they tried to restore it from the Time Machine backup drive, it would not work. Their guess is that Time Machine cannot restore from a drive that is "case sensitive."
Any thoughts on how I can convert my time machine backup data from a "case sensitive" state, to a "non-case sensitive" state? I've tried to just drag and drop the files from the case sensitive formatted drive to a new drive that I have that is formatted non case sensitive, but I get the following error message:
"The volume has the wrong case sensitivity for a backup"
I just really want my data back - I thought TimeMachine was the way to go (and was supposed to work) but unfortunately it is not.
Any help you can provide would be greatly appreciated.
Thanks,

How to convert case-sensitive to extended journal format

I have two apple computers (extended journal format) that have been backed up via a time capsule. I have just noticed that the TC is formatted as case-sensitive. I do not know why case-sensitive. In an effort to ensure consistency of file format then I seek to somehow remove case-sensitive formatting. I presume no/minimal underlying case-sensitivity issues within file names as source data is not formatted in case-sensitive manner.
I have tried SuperDuper to clone the TC to an external HDD but the application cloned the formatting in addition to the data.
I have attempted use of Disk Utility to copy content from source (TC) to destination (HDD) but this yielded error messages that noted different file format types.
It there a way to convert/remove case sensitive formatting from TC?
I appreciate that I could simply reformat TC to extended journal format but this would presumably erase all my backup data.
Any guidance most welcomed.

So I guess my choice is to "leave well alone" as Pondini suggests and accept the fact that cloning TC onto HDD has now formatted my new HDD as case-sensititive.
Actually, you may have two choices, depending on how you're going to be backing-up to the new HD:
Your best bet, by far, is to back up to it directly, rather than connecting it to the TC. That's much faster and more reliable. If so:
* Leave the TC backups alone. Reformat the HD as case-ignorant and let Time Machine start fresh on it. You can always see and restore from the old ones via the Browse... option, per Time Machine - Frequently Asked Question #17.
* Format the HD as case-sensitive and copy the backups from the TC to it. But don't copy the whole sparse bundle; copy the Backups.backupdb folder from the sparse bundle to the top level of the HD. (Sparse bundles are used only for network backups.) See #18 in the FAQ; you'll need the 4th procedure (copy network backups to be used locally.
But if you're going to connect the HD to the TC and back up to it that way, it doesn't matter how you format the HD, since the backups must be in a sparse bundle, that has its own format. Two choices for that:
* Leave the TC backups alone. Connect the HD to the TC and select it as the TM destination, and Let Time Machine start fresh on it. You can always see and restore from the old ones via the Browse... option, as above.   (There is a way to speed up the first backup; see the blue box in #Q2 of Using Time Machine with a Time Capsule.)
* Copy ("Archive") the TC's internal disk to the external HD, per the green box in #Q6 of the same article. Then select the external as your Time Machine destination via Time Machine Preferences.
Is this simply deferring a problem issue to another time (aagh)? Or to somehow try and remove this inconsistency and remove case-sensitive formatting from all tech items, even if this might mean reformatting and losing old backup data?
No. There's not really a problem, unless you change the case of file/folder names and try to restore the old ones to the same place via the TM browser, per the link in my earlier post. That's the only possible downside.
Does Time Machine require case-sensitive formatting on its destination drive?
No. It's the default, but case-ignorant is fine, unless you ever want to add a case-sensitive volume. Then you're in a pickle.
Or does Time Capsule only function witih case-sensitive formatting?
No. The TC's actual disk is case-ignorant; it's only the Time Machine sparse bundle that's case-sensitive by default.
The benefit of case-sensitive formatting as Apple default seems rather unclear to me
It's the default only for Time Machine backups. Everything else defaults to case-ignorant.
The advantage is, once you've been backing-up your internal HD for weeks, months, or years, and want to add a case-sensitive external HD to be backed-up, you can.   If the backups are case-ignorant, you can't.

Time Machine suddenly refuses to backup to non case-sensitive drive

There is another thread on this which for some reason is marked as resolved, so I thought I'd post a new thread. Suddenly after months of no complaints I get the following error:
*+Time Machine Error+*
+A volume you are backing up is case-sensitive, but the backup volume is not.+
+To Select a different backup volume, or to choose not to back up the case-sensitive volume, open the System Preferences and choose Time Machine.+
The only thing I've changed is that yesterday I ran Software Update. Unfortunately I can't remember exactly what was updated, but I suspect Quicktime was one of them since I needed to reboot. So now I'm at 7.4.5 in Quicktime.
Time Machine refuses to backup my drives now complaining about the case sensitive filesystem. The thing is, *NONE of my drives are case sensitive.* Looking at the Change Drive window in Time Machine, I see that most of the drives on my system say "reforat required" if I am to use them with Time Machine. All drives on my system are *Mac OS Extended (Journaled)*. The fact that some drives are not requiring a reformat and some are, even though they all are the same format is quite puzzling.
I took a spare drive and allowed Time Machine to reformat it for it's use. It has now reformatted the drive as Mac OS Extended (Journaled, Case-Sensitive).
Can anyone shed any light as to why TM would suddenly require my backup drive to be case sensitive when none of my drives are?
This make no sense...

Ok - Running Disk Utility Verify on both the system disk and the TM disk seems to have magically stopped this error. Note that Disk Utility didn't actually find or fix any problems with either disk. The problem just went away....
It doesn't make any sense.

I am unable to reinstall Photoshop CS6 (I do have the serial number) on my Macbook Pro 10.9.5 (Mavericks os). and am getting the message "Installation on case-sensitive volumes is not supported. Please choose a different volume for installation." I am further told that "Adobe apps cannot be installed on case-sensitive drives, you need to Install the product onto an HFS+ or HFSJ non-case-sensitive drive."
What I don't understand is this: I originally bought and installed Photoshop CS6 back in March 2013, and it worked fine. Yesterday my hard drive had to be replaced and my computer person salvaged as much of what was on it as he could, but now I have to reinstall Photoshop. 1) Why did it work before and it's not working now? 2) Is there anything I can do that does not involve reformatting the hard drive?

It means what it says. The "computer person" formatted it wrongly/ unsuitably. it needs to be formatted again.

Installation of Photoshop CS6 (Extended) on Case-Sensitive Drives

I understand that under the "system requirements" the Adobe website says that you can't install PS CS6 (Extended) on case-sensitive drives (I'm using a MacBook Pro, OS X v. 10.7.4). This seems to have been the case at least since CS5.
I didn't see this, and I bought (quite excitedly) the update from CS PS5 (Extended) to PS6. I had NO PROBLEM installing PS5 on this drive.
Of course, as other users have indicated, the installer refuses to let you install on a case-sensitive drive (e.g., no options to install on another disk). There is also no mention that CS6 must be installed on the boot drive.
Requiring installation on the boot drive has serious implications for those of us who require case-sensitive drives for other work; I don't want to have to reboot from another drive when I use PS, and switch back and forth -- that's simply foolish.
From my point of view (as a user, granted), this is lazy programming, and this needs to be fixed ASAP. At least in my case, I have a $400 lump of software just taking up space, when I want to be up to my eyeballs enjoying PS6 in all it's glory.
Outside an Adobe fix, I don't see a solution to this problem. If I wipe my drive, format it as not case-sensitive, then I lose functionality for other critical work. Further, I'm not sure that the process of wiping the drive, formating it as non case-sensitive, and restoring everything from TimeMachine would even work (since the backup material is coming from a case-senstive drive and trying to go to a drive that is not case-sensitive).
The REALLY frustrating part is that I've installed Photoshop 3, 4, and 5 (and from much, much further back) on case-sensitive disks -- all with no problems. It's only now that the issue smacks me in the face.
There's got to be a work-around, if not a "real" solution.
Whatever help you might be able to offer would be greatly appreciated; details can be sent to cdretk at gmail dot com.
I have hope, and I thank you in advance.

Whether it is Apple or Adobe's work flow isn't the issue. Between the two
of them, if they are going to support both naming variants, then at both
Adobe and Apple:
1. You MUST use the same case file names. (E.g. FrameWorks and not
Frameworks) EVERY time. And refer to them in your programs and
configuration files the same way EVERY time.
2. You may NOT in your development code use different but case invariant
file names for different files.
3. Your libraries must do the Right Thing.
What gets me is that few others seem to have this problem. Perhaps Adobe
needs to abandon Apple development software, and roll their own outside the
standard system libaries.
Further searching shows that it is not a problem unique to Adobe. The
games BeJeweled, and BZFlag have this issue, as does the Steam game support
systems.
In every case I've run down to date, it has been a violation of #1.
Now there are workarounds: A script that creates appropriate symlinks on
case sensitive file systems would be fairly easy. It would impose some
minor amount of extra overhead.
I bought a copy of Adobe Creative Suite. I returned it unopened. You lost
a sale. Furthermore, until it is fixed, I will mention this at every
opportuity as an exampled of a combination of sloppy workmanship, and
customer indifference on the part of Adobe.
Tell your bosses, Chris, they need to fix this.
Respectfully,

Time Machine Case Sensitive Restore to Non-Case Sensitive

I have a MacBook 2.4GHz white laptop with OS X 10.5.5. Previously I formatted the drive as Mac OS Extended Journaled Case Sensitive. I have determined that I cannot install Photoshop CS3 onto this drive without doing some fairly tricky work-arounds.
To fix this problem "fast", I used my Time Machine backup to restore my primary drive after I had reformatted it as Mac OS Extended Journaled. However, as part of the restoration process, time machine formatted the drive again (as case sensitive) and copied the software. This puts me back where I started.
Is there a way to alter the settings of time machine such that it does not format the drive or does not format the drive as case sensitive?
Is the only way for me to do this to reinstall OS X 10.5 on the formatted drive (not case sensitive) and copy the files over from time machine? Is is possible to copy (not restore) files from the time machine drive?
I would appreciate any help. Thanks for your time.

Glenn Carter wrote:
Unfortunately, an Erase and Install is probably the only way you are going to fix this. As you have discovered, it appears that "Restore System From Backup..." reformats the destination drive to match the state in which the backups took place.
The TM backup may not have the ability to rename dupes that might occur if some files have identical names save their case.
Even a reformat and reinstall may not work unless any pseudo-identical files are first renamed.

Case Sensitive External Drive for iTunes

My iTunes Library is currently stored on a case sensitive external drive. I am moving it to another drive that I found out is formatted as a non-case sensitive (both areJournaled). When I tried to move my iTunes Library, it would not copy because there are apparently some duplications that are different in case and this causes a problem when duplication to a non-case sensitive drive.
I figure I have two options:
1) Reformat the new drive to be Journaled and Case Sensitive
2) Go through the tedious process of identifying which files in the iTunes Library would be duplicates in a non-case sensitive drive. There could be just a few or hundreds (or even thousands).
What is the disadvantage of using a Case Sensitive drive for iTunes (option #1)? I may also store some other files on this drive.
I noticed that all my other drives, on both my desktops and external are formatted as non-case sensitive.

If you can get to the two metadata files that iTunes keeps on the old PC, then you have several options. See: What are the iTunes Library files?
1) Use the 'iTunes Library.itl' file on the old PC to completely recreate your Library. You will have to place all the music files/folders in the exact same location on the new PC as they were on the old PC. That drive letter and directory path. Then copy the older ITL file over the current one on the new PC. Open iTunes and you'll have a clone of the old PC's Library. As you have been using an ExHD to store the music, this would be my preferred choice. It's easy to remap the drive letter of an ExHD, if needed.
2) The other way is to 'File=>Import' the XML file and recover the Playlists from there. They will not be in any folder structure as they were in the previous iTunes. Also, any playlists that depended on ratings, play counts and last played will be changed, as those attributes have not been carried over using this method.
Post back if you have questions.

How do I convert a case sensitive drive to a case insensitive drive?

I have recently purchased a MacMini Server, and installed the 2 internal hard drives in a RAID 0 configuration to obtain the speed and 1 TB capacity, but unfortunately (rather stupidly in retrospect) formatted the drive in case sensitive mode.
On installing the operating system and multiple applications, everything seemed to work well until I tried to install Adobe Acrobat X Pro. This application refuses to install on a case sensitive formatted drive, which I now understand is a common problem.
The question is how can I convert to a case insensitive format without reinstalling all of the software from scratch?
I have a Time Machine backup, and the easiest thing for me would be to reformat the drive, and then restore from the Time Machine backup.
Will this process work? Or will there be some complications and files that will not function if they were originally installed on a case sensitive drive?
Any help is appreciated....

iPartition can do it ( http://www.coriolis-systems.com/iPartition.php ).
from iPartition Help:
Make Case Sensitive/Case Insensitive
HFS+ now supports a case sensitive format as well as the usual case insensitive format. On a case sensitive volume, the names “Readme”, “README” and “ReadMe” would all represent different files, even if they were in the same folder.
This option allows you to non-destructively change a case sensitive volume into a case insensitive one, and vice-versa. If you are going from a case sensitive volume to a case insensitive volume, some of your files may be renamed automatically by iPartition so that they do not clash. If all of the files in the table below were in the same directory, the right hand column shows the new names iPartition would choose for them:
Old name New name
README.txt README.txt
ReadMe.txt ReadMe 1.txt
Readme.txt Readme 2.txt
README README
ReadMe ReadMe 1
Readme Readme 2
Notice that iPartition puts the number before any file extension.
N.B. iPartition does not transform filenames with numbers on the end back into their original forms. There is no way to tell which files were renamed by the user and which were renamed by the conversion process.

How to get Case Sensitive Check Box at Search Page

Hi Everyone,
I am trying to get case sensitive check box at the bottom of the search page, for that we have to set any propert or we ahve to do anything else.
Please Help!!!!
Thanks,
Amit

Have never really thought of it. One thing you need to do is set the Case Insesitive Searching Option correclty in PeopleTools Options. I can't find any other setings. But it might have to do with the fields that are on your Search record. My guess is if any of the Search Fields are of type Character and format Mixedcase then the Case Sensitive check box will be displayed automatically.

Time Machine error message - "case sensitive volume" conflict

After apparently working fine for a month or so, Time Machine is giving me an error message that reads, "A volume you are backing up is case sensitive, but the backup volume is not." I don't know what this means. How do I identify the case sensitive volume, so that I can exclude it from backup, assuming that's the correct action?
Help is appreciated! Thanks

I've had this occur to me too, but I think that maybe - and it's important that I underscore the 'maybe' part - I might have put my finger on the cause and, perhaps, the solution.
In my case, I happened to have had Disk Tools open when I downloaded a .dmg disk image. It seems that Disk Tools tends to 'remember' the disk image as a mounted volume, even though it's no longer on the desktop. I don't know what this might have to do with Time Machine, (and hopefully there is an Apple tech who is monitoring this thread), but when I deleted the disk image from the Disk Tools volume list, the "Case-Sensitive" error went away.
I don't know if this is really the root cause, but if anyone is experiencing the same "case-sensitive volume" error, try opening Disk Tools and see if there is a disk image volume appearing at the the bottom of the Disk Volumes list. If so, select it (or them, if there's more than one), and do a Command-Delete to remove them. Once the disk-image volumes have been removed from the list, try running Time Machine again. If the error is gone, post here so that other readers can try the same thing!
Best,
Tom

Web URL case sensitive

I am using iPlanet as my app server & web server. My URLs are seems to be case sensitive. How could I eliminate this?. My OS is Windows.
The actual folder name in windows in "AA", which in in the doc folder of iPlanet.
while accessing
http://localhost:81/AA/index.jsp, its working but
http://localhost:81/aa/index.jsp is not working.
Whats the prob.? How could I eliminate this?

domain names are not case sensitive.
the path after can be. I believe this depends on the server's file system. Windows machines are not case sensitive, so the path for a server on a Windows PC is usually not, but Unix system are case sensitive in the file system, so the path for a server on Unix is as well.
However, the general rule is to always define domain names in all lower case (they are case insensitive anyway) and to assume case sensitivity for the path in the URL. Case insensitive servers/file systems won't care, and case senstive ones will be correct.

Is Oracle9iAS Relase 2 case sensitive????

Hi all,
I am new to oracle9iAS. I wolud like to know whether oracle9iAS is case sensitive towards the JSP names accessed. If so, is there any option to make it insensitive.
Thankx in advance
kishor

Right. And for resource names, case sensitivity depends on operating system used. That's why it's better to use case sensitive system like Unix* than insensitive like Windows*. It cannot happen one resource has many different names and thus, your JSP compilations (you mentioned in another topic) will get always the same name.

Change from case-sensitive disk format to the normal Mac OS Extended.

Hi,
I need to change from a case-sensitive disk format to the normal Mac OS Extended Journaled version.
I have no external HD fitted, but I do have some DVD-Rs. I need to restore the data from 2 users, including iTunes and iPhoto files.
What's the best way to achieve this?
Many thanks,
Tris.

I just got off of the phone with Adobe support. They told me they knew the solution, but that they would not tell me tonight. I had to call back between 6:00 am and 5:00 PM tomorrow. That does not work with my schedule. So I googled some stuff and found that Adobe CS 3 is not supported with Case-Sensitive file systems. So OK, let me install this to my other MAC that has a non case sensitive drive. Same error. Even though I have a non case-sensitive drive, the OS is on a Case-Sensitive Drive and I am never prompted where to install like most all other Mac Software.
I have always formatted case-sensitive. So I am thinking to myself why not start using a non case-sensitive drive. Well, to start off I want it case sensitive. I enjoy web programming and like this feature. Sure it is not needed, but I am glad Apple offered me a choice. And I am sure there are many other reasons why to use it. Also I would be interested in knowing why non case-sensitive drives are supperior.
Why is this a requirement now? I have used Adobe software in the past without this specific issue. I also have Large TB drives and do not know how to 'safely' do this. You will not catch me jumping through this hoop. I will not risk the change to the file system. And I can not be expected to format my drive. I just wonder what Adobe would say tomorrow if I called.
The Direct line I was given by adobe is 800-642-3623 for support on this issue. You don't need anything else but to call this number and ask. You can not get through after hours though.
Wow, I just can't believe this and the lack of interest Adobe had with me.
I hope I can get a refund on the software. Until I am able to downgrade my file system format, I do not want to sit on Adobe's bill. I will buy it again assuming I learn I can't do without PS CS3.
