HD constantly needs repair

If I were to run VERIFY DISK every day on my MacBook I would get the same results: files differ by one file and folders differ by one folder...requiring a REPAIR DISK. This is getting old...how can I determine which file is the culprit here?
I obviously don't run REPAIR DISK every day, but I've verified it may days in a row and it always needs it. It seems to hold for maybe 8-10 hours before something goes wrong with this one mystery file.

V.K....I know I have to repair from the OS disk...been in the computing business since 1983 Just thought there might be some trick to finding the offensive file, since there is always just one file and one directory. Every other Mac I've had has never given me this specific problem.
I'll try Disk Warrior, but won't hold my breath. If I end up having to reformat, I'll just move off my data, reinstall SL and updates, then all 97 app (yuck) as bringing back a clone just might bring back the problem. Remember, it's a "file" causing the problem...not a sector on the drive.
what is the exact error message? does it say that the number of files is different by one? then reformatting (not just erasing ) the drive and cloning the clone back will fix the problem and won't reintroduce any back. file system error of that sort generally means one of two things
1. an orphaned file that lost its place in the directory. running disk repair should fix that and the orphaned file will be placed in the lost+found folder at the top level of the drive.
2. a leaking inode that's pointing to a nonexistent file or folder. this again ought to be fixed by disk repair. but either way doing a file level cloning can't carry over problems like this to the clone. just don't do a block level cloning and you'll be fine.

Disk Permissions constantly need Repair

Hi,
I've just upgraded to 10.6.5 and noticed that each time I log in, my disk permissions need repair. I've updated everything, but still seem to have permissions problems. Any help would be appreciated. These are the errors.
Many thanks!

Yeah, that advice is all over the place. It certainly won't hurt. But the benefits of doing it are, IMO, greatly exaggerated.
Repairing permissions can be a useful task if you are having a problem that can be traced to incorrect permissions on an application, folder, or file that is installed with the Mac OS X installer. Because those are the only things (and only a subset of those at that) that repairing permissions fixes.
But somewhere along the line, people starting using Repair Permissions as some sort of magic pill that can fix any ailment. Computer slow? Repair permissions. Screen flickering? Repair permissions. E-mail message won't go on the trash? Repair permissions. That advice is handed out (ill-advisedly IMO) on a daily basis on these forums. And, of course, there are those who advocate repairing permissions both before and after any system update. IMO that advice too is based on urban legend. I never do it.
If you do repair permissions, and it finishes with "Permissions repair complete", then it's done and you don't need to worry. The "errors" it returns are not errors at all and nothing needs to be fixed. They're just "messages", not errors. If you don't want to see them, simply uncheck the "show details" box.
If Repair Permissions finishes with "permissions repair failed", or "the "underlying task reported failure on exit", then worry.

My iMac crashes using iPhoto, the database constantly needs repair, and upgrading software patches causes the screen to hang

I am not sure what is going on. I have kept current with all upgrades and now when I attempt upgrades my system will hang on the white screen, forcing me to turn the machine off and on.
iPhoto has been really buggy (latest version) - keeps telling me that I need to repair my photos. Last night I was working on a photo book and it crashed twice.
Once it rebooted the iMac, the second time while uploading the book it crashed iPhoto.
Since this is past apple care - I am not sure what to do. I am in the US and I can't find any information on pricing for a visit to the genius bar.
The only thing I have going on with this machine is two seperate user accounts that access a shared iPhoto and Music library on the shared portion of the HD.
Thanks for any help.

Back up all data, then follow the instructions in the support article linked below:
iPhoto '11: If you see a message that iPhoto can’t access one or more photo files
If you still have problems, try the other options in the "First Aid" dialog.

Volume needs repair AND hard drive problem...

OK so I have an Intel Based iMac and its about 1 year old. Randomly I got a message saying that the hard drive disc space is almost full, which makes NO sense. I have a 250 hard drive and I use it mainly for video editing. Before I got this message, I had about 100 GB left on my hard drive. I have NO CLUE where 100 GB went to, and i know it was not from video. Also I went to the disk utility and it said "Volume needs repair" and it gave me an "The underlying task reported failure,". Im not sure what to do and I'm hoping you guys will.....if this has been asked before, I apologize.

Yes, you can delete it, but it indicates a bigger concern namely your maintenance scripts aren't running regularly to clean up the logs or you have a problem in the system or an application that is writing huge amounts of information constantly into the log file. You should check the log using the Console application (Utilities folder) and examine its content to see if this is the case.
You should also read the following for information on installing utilities that can assure the maintenance scripts are run as well as other information on system maintenance that can help keep your computer running better.
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.0 is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.6.1 is Leopard compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. The current version, 1.5.1, is Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that presently AppleJack is not compatible with Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
8. Data Backup (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.

Can I purchase Mountain Lion and make a flash drive bootable? I do not want to install it on my Macbook Pro. I have Snow Leopard on my Macbook Pro now, and due to my hard drive needing repair I need to boot off of another source, like my flash drive.

Mac OS X has a built-in disk diagnostic and repair program called fsck or file system consistency check. Here’s how to verify and repair your startup disk with fsck. As soon as you hear the startup tone, press and hold Command-S on the keyboard. Keep holding down those keys until you see a black screen with white lettering. This is called “booting into Single User Mode.” As the Mac boots in this mode, the screen reports each step of the process. The line should end in root#. Right after the root# prompt, enter the following: /sbin/fsck -fy
If repairing the disk in single user mode fails, it means one of two things. Either your hard drive itself is failing (a hardware failure), or the directory damage on your hard drive is beyond the capability of the built-in repair procedures in OS X.

My back up is not working. I get a error message, "internal disc needs repair" Any idea what this means?

Hi, as above, back up not working, message "internal disc needs repair". Can somebody help with the meaning of this.

Explanations:
Folder Depth: This number indicates how many folders are nested inside each other. If a disk contains only three
folders and Folder A is inside Folder B and Folder B is inside Folder C, then this disk has a maximum folder depth of
three. Folders nested too deeply can cause software compatibility problems.
Property List: This is a standard file format for storing data and is often used to store preferences. The names of
these files normally end with a .plist file extension. Corrupt property list files can cause system instability.
Resource Data: This is an older file format for storing data and was often used to store preferences. The names of
these files normally end with a .rsrc file extension. Corrupt resource data files can cause system instability.
System Symbolic Link Files: These are files used by the operating system that are similar to aliases. If these files are
damaged it may prevent startup or cause system instability.

Went back to Disk utility and now it says that my hard drive doesn't need repair! whats going on! can anyone help?!
Thank you

Two things off the top:
128MB are GUID partitions that are not user volumes.
There is also a 200MB EFI partition as well.
Drive Genius needs to get their program updated.
You need to work from an "emergency" boot drive to repair your boot drive, RAID or no. I hope you are and not from CD or DVDs.
Forget about Permissions. They are very minor. They only have to do with ownership and security and based on what is in
/Library/Receipts
Trying to verify? all you want to do is repair and rebuild.
If you ran DU and DW and did repair and rebuild and WROTE NEW DIRECTORY and the problem remains, erase and restore, or...
+I am useless with RAID and have no idea...+
Don't use it except to test, learn, experiment with. But not for system drive.
Above I asked, "are these a matched pair of drives" ie, same make, (looks like same size), vendor, model? they should be. Less chance of trouble if nothing else.
ON the boot volume, do a Get Info when you click on the drive, look for "Ignore Ownership on this Volume" and make sure it is NOT CHECKED. It can't be to repair permissions and be bootable.
The underlying cause of disk errors may be marginal or bad RAM. Test those FBDIMMs. Run Apple Hardware Test and Memtest (even Microsoft uses Memtest for Vista).
Drives rarely break. Systems do. Directory and btree catalogue and volume information blocks do.

After upgrade to Leopard OS thinks my External Hard Drive Needs Repairs

After I upgraded to Leopard on my POWERBOOK G4, on startup with my Seagate External HD 400GB (ST3400601-CBRK)hooked up with Firewire, The OS displays a message DISK REPAIR and locks the Seagate giving me "limited fucntionality," basically I can't use it.
If I run Disk Utility, I don't get the repair option, only verify. When I hit "verify" it tells me it can't do anything because the disk needs repairs.
On the Seagate already is an eDrive Partition with TechTool Platinum It shows everything is fine The Disk in 100% good shape - no fragments, The Files and Finder index are all fine.
Does anyone have an idea what's wrong?

Zap the PRAM and Reset the SMC, then try again. If the problem remains, update to 10.6.8 and repeat.

•The article suggests using a third party utility. Disk Warrior and Tech Tool Pro are the best utilities for this job. You will need to get one of them and run it, by booting from the CD, or installing it on an external firewire drive or on a second Mac which you can then run in Firewire Target Disk Mode.
Please do post back with further questions or comments.
Good luck.

Hard Drive Needs Repair - Cannot Be Fixed?

I've been having trouble with my MBP as of late.
The problem first originated when I was having trouble with some DJ equipment that uses an external hard drive. When I called the tech support for the DJ equipment, I was told to run Disk Utility on both the external and laptop hard drives. The external came back clean but the hard drive on the MBP gave reason for distress.
I clicked "Verify Disk" and it begins to run. It finds a few issues and says "Volume Macintosh HD needs repair." and allows me to input my password. However, at that point, a new window pops up saying that "Underlying task failed to unmount" and then goes back to the Disk Utility window. My concern is that after that window closes, the "Repair Disk" button is still grayed out so not only is there a problem, I cannot fix it.
The computer has been acting weird lately as well, like deleting all shortcuts on the left side of the Finder except my user shortcut, desktop, network, and Macintosh HD (ie: Apps, Docs, Music, Pics, and Movies disappeared).
Any suggestions? I have AppleCare till mid-2009.

You try Disk Utility first. Insert your Tiger installer disk and restart while holding down the 'c' key. Select your language and then from the menu>Utilities>Disk Utility. Select your hard drive and then Repair Disk.

Disk Utility - Partition map needs repair because a data partition needs loader space.

I just finished setting up both my OSX and Windows installs from scratch after fitting an SSD, which in-turn was right before my logic board died and Apple replaced it, now it looks like I have some sort of hard drive issue brewing.
This was my plan for the SSD, and how it currently displays in Disk Utility although that wasn't the case earlier:
And in Terminal:
My intention was to have two boot partitions for each OS, 'Macintosh HD' and 'Win 7 Pro' and a third shared data partition 'Projects' on the SSD, which I made in Drive Genius after installing Boot Camp. I don't want Macintosh HD accessible from Windows because I'll be using Paragon HFS+ or MacDrive to give write access and don't want OSs stomping on other OSs turf, hence needing three partitions. Everything looked fine until I just checked Disk Management under windows and realised it couldn't see the Projects volume. Even though it's fine in OS X, it was just marked black/unallocated space.
So I booted back into OSX, all my files look fine so I ran Disk Utility and the Partition tab looked really odd - unfortunately I didn't get a screenshot. All volumes reported their size correctly but visually, Macintosh HD took up most of the drive. I could see 'Windows 7 Pro' under this, but the Partition Layout section had a scrollbar, which if I scrolled down showed 'Projects' squished into a tiny gap at the bottom. I ran a Verify, which reported no problems, and at some time since the Partition Layout has reverted to how it should look (as in the screenshot above), with 'Projects' book-ended by "Macintosh HD' and 'Windows 7 Pro'.
Now when I run a Verify on Macintosh HD or Projects volumes, it says there's no problem, but if I run one on the drive, I get this message:
Volume Macintosh HD on disk0s2 has 0 bytes of trailing loader space and it needs 134217728 bytes
Problems were found with the partition map which might prevent booting
Error: Partition map needs repair because a data partition needs loader space.
I've only managed to find one other mention of this error here, but the fix is not relevant to me because I don't have Sophos installed. I've tried Single User/Safe Mode but it just boots into normal mode, so I can't do a fsck -fy.
** /dev/rdisk0s2 (NO WRITE)
Can't open /dev/rdisk0s2: Permission denied
That value in bytes is exactly 128mb, so I suspect the problem lies with one of the invisible partitions that show up in iPartition and Disk Management under Windows, but not in Disk Utility. I have backups and I suspect the root of the problem is partitioning in iPartition after installing Boot Camp, but I've never had issues with this approach in the past so I'm wary of just giving up and reinstalling Windows again will be massive hassle because I no longer have a SuperDrive and last time it refused to install from USB.
Anyone have any idea what's going on? It seems like the sort of issue Disk Utility should just handle, at least in Recovery mode, but it's not playing ball. It also doesn't seem like a massive problem since my files all look fine and performance is OK, so I'm reluctant to do anything major.
I'll update with a shot of the drive in Disk Management from Windows in a few minutes, in case that sheds light on anything. Thanks!

Similar issue here. I manually partitioned my hard disk for triple boot (using Gparted on Linux), then everything was just fine until I ran bootcamp, to do something as simple as create a boot USB.
I get the same error as a result and have to work my way into booting, by resorting first to a Linux live USB, then restarting from the live USB, to finally reach my rEFInd boot manager, or whichever boot manager should be initialized at startup.
I suppose that the cause in my case is that some operation "scratched" the protective MBR. See this:
http://www.mactech.com/articles/mactech/Vol.23/23.03/APMtoGPT/index.html
I am hoping to fix it using an external Yosemite installation media: see this guide -
http://www.macworld.com/article/2367748/how-to-make-a-bootable-os-x-10-10-yosemi te-install-drive.html
And as a last resort to reinstall.
I'll admit I am negatively surprised. I need this computer for professional reasons, and for the sake of "preserving the integrity of OSX", measures defined by Apple instead tend to make partitions far easier to damage. And this problem seems to affect a number of users.
As for what I have to go through to fix it: a 5GB download, during which I have to register my credit card to the Apple Store. "Pay first, get your free software next."
IF Disk Utility can fix it, from the external media, then fair enough. The hassle is unpleasant but it files as "a choice".
Otherwise you can file it safely under software design calamity.

Yesterday I ran Disk Utility and came up with hundreds of permissions that needed repair. I hit the "repair permissions" button and waited until it said they were repaired, but just for fun I hit the "verify permissions" button again, and they all came back! I did this several more times and every time I would hit "verify permissions" I would get the same list. What's up? I've always suspected diagnostic programs, but this is Apple's own!

Ignore them. They aren't errors. You will keep seeing the same ones. As long as you get the message "Permissions repair complete," you're OK.

HD problem - disk utility says "1 HFS volume checked" "Vol needs repair"

This all started with very slow response when applications were opened on iMac purchased 10/07 - went to Disk Utilty and tried to Repair Disk - but not allowed to click on that option(still grey). So, went to Disc 1 of Installer set of disks , inserted in drive and attempted to reinstall Mac OS X that came with Oct '07 (Tiger-right before Leopard became standard) purchase. When I get to the Select A Destination part of the Install MacOS X directions, there are no choices(ie- HD not recognized). Went to disk utility option available with the Installer disk and did a Repair Disk option. Following messages in RED
Invalid Volume Header
Invalid Mode Sgtructure
The volume Mac HD needs to be repaired ( ie- Volume check failed)
then Disk Utility boxpops up andsays Error: The underlying task reported failure on exit
Finally
1 HFS volume checked VOLUME NEEDS REPAIR in red
Huuuum.
Next step? I am using my wife's PC to send this HELP message and it's painful. Rescue me as the song says! Is it time to box up for Apple store visit, or ......

Houston, welcome to Apple Discussions.
It appears you have some directory damage on your hard drive. Disk Utility cannot fix some of these type problems. DiskWarrior can probably fix your problem. DiskWarrior by Alsoft

A crash, volume needs repair?

Hi, I have no idea what has happened. It's embarrassing but I can't even tell you accurately what OS X I was using but all my software was up to date. When I try to open applications like Safari, it says "you cannot use the application Safari with this version of Mac OS X" The same goes for iTunes and other apps. Some programs just quit unexpectedly when I try to open them. Seems like it reverted back to a very old operating system I didn't even know existed. Even the JPEGs open with a different program I don't use. When I click "about this mac" it says the memory capacity is 512 MB when I know it usually 250 GB and I currently have 25 GB free. I tried Disk Utility and the error messages read exactly as followed: Volume bitmap needs minor repair. Invalid volume free block count (it should be 6873884 instead of 6873859) The volume Machintosh HD needs to be repaired. Error: the underlying task reported failure on exit. First Aid failed. Disk Utility stopped verifying "Machintosh HD" because the following error was encountered: The underlying task reported failure on exit. HFS volume checked volume needs repair.
I stopped messing with it because I have no idea what to do and I don't want to make it any worse. I have installation disks buried in storage but I'll get replacements if that's what it is. I'm panicked. Please help

Welcome to Discussions - boot from your install disc and use Disk Utility to repair your volume. If that fails, get hold of DiskWarrior and use that.
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
When you have finished, reboot and repair permissions from your hard drive.

Mac book pro spinning on startup but never gets to log in screen, repair disk says unable to repair, 2007 computer running Lion, how do I reinstall Lion to the Mac HD, which is the disk that needs repair, but cannot be repaired?

2007 MacBook Pro, was shut down properly last PM. Today on startup, spins and spins but cannot get to log in screen. Held option key with restart and using disk utilities the mac HD showing needs repair, but cannot be repaired. Says save as many files as possible and reinstall software. Can't save files, can't get into them. Willing to reinstall without saving, but can't because only disk option for the reinstall showing is the repair disk, and it is showing as locked. What to do?

Sounds like the drive is starting to fail. Have you ever change the drive in that system? If not then it is time to think about doing that, the sooner the better.

HD constantly needs repair
