IMac repeatedly corrupting file system.

Right. This is a REAL head-stractcher I've got on my hands.
I've got a white intel iMac that killed a hard-drive. Replaced that with a new WD disk. Then updated to 10.6.6 (EDIT: this is a known issue with some machines...), that ruined the file system. Did a clean install & updated to 10.6.5, restored user files & clean installed apps. This worked well for a few weeks.
Now... here's the real bugger...
It has gone down again. Similar to what 10.6.6 did. fsck reports 'invalid node structure'. Nothing can repair it, Disk Utility, Tech Tool, Diskwarrior. All failed.
Not a file-recovery issue, I have a TM backup.
TechTool 5 tells me that RAM & HD are fine (extended tests) same with Hardware Test on OSX disk.
I CANNOT FOR THE LIFE OF ME figure out what is going on here. Nothing out of the ordinary happens. Shut it down, come back to it the next day: boots, Apple logo, spinning progress indicator, powers off.
Verbose / single-user show 'invalid node structure'.
My last resort is that it could be the death of the machine: maybe the processor is handing off corrupt commands = ruining the file structure?
Basically, I just don't know. It seems fine for a while, then dies suddenly & mysteriously.
HELP?!

Addendum to my last post (I was in somewhat of a hurry):
If you will take a look at this:
http://www.alsoft.com/diskwarrior/details.html
The last time I ran it on my current iMac, the directory was 36% out of order. That appears strange - I have a 1 TB hard disk and so far, only about 100 GB data on it. So, my non-techie take on it is that it will simply write all over the place - wherever there is room - and that is how you wind up with messed up directories. My suggestion is that if you use your machine heavily to run it occasionally.
Note that 1) you cannot run it from the boot disk and 2) the current version of DW is unable to boot the new iMacs. Since booting from the DW disk is a pain anyway, the simple solution is to install it on your internal and then create a bootable clone of your system (which will obviously include DW) on an external. Then, when you want to run it, simply boot from the external, run it and when done, choose to restart from your internal. Done and all is well with your hard disk.

Help! Corrupted file system....

Hi all,
One of the partitions on my external hard drive (Mac OS Extended Journaled) has a corrupted file system. This occurred right after I installed the latest NTFS-3G driver, which allows read/write of NTFS drives (http://macntfs-3g.blogspot.com/). The external HD was accessed via my Airport Extreme (so it was an "Air Drive"). When I connected it directly to my MBP and used Disk Utility to Verify/Repair, I got the following error messages:
*Invalid node structure*
*Invalid B-tree node size*
*Volume check failed.*
*Error: Filesystem verify or repair failed.*
What is going on here and how can I fix it??? I should note that I've already uninstalled NTFS-3G but the problem persists. Also, it's not a physical problem with external HD, since the other two partitions on the disk appear fine.
Any help would be much appreciated!

It would have to have been a pretty big coincidence since it happened immediately afterward...but you're right, I have no way of knowing for sure. I've never had a hard drive do this; I've been a windows user until about a year ago. I thought the HFS+ file system was supposed to be better...Ironically, the good old FAT32 partition on the same drive is still going strong.
Disk Warrior is a $99 purchase. Does anyone have any other suggestions for me to try before I plunk down the cash? BTW, Drive Genius 2 and also failed to repair it.

Recurrent corrupt file system of internal hard disc

Hi,
on my MacBook Pro Late 08 I get some file system corruption over and over again. Normaly I would guess having a defect hard disc but I have already tried three different discs. The problem always comes back.
I recognize the corruption by having multiple crashes of several applications (Firefox, iPhoto, iWorks, ....) having some exception type of EXCBADACCESS. This type seams to indicated that something cannot be read correctly anymore. After repairing the disk everything works fine again.
Is it normal that MacOS filesystem is not that stable and gets corrupt from time to time? I cannot find out any reproduction pattern so far.

I have exchanged the original disc to a larger 500GB/7200 2 month after getting the new MacBook. To narrow down the problem I switched to a 500GB/5400 another 6 month later. I always moved with a SuperDuper Backup from disk to another. My disc usage is about 90%.
I tent do believe it has something to do with the power management of the Mac. Between a healthy file system and a corrupt one is always one or more system sleeps.
But the output of the disk utility is also weird. Three successive runs state at the end:
1)
Invalid node structure
The volume MacBookPro internal could not be verified completely.
Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
2)
The volume MacBookPro internal was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
3)
The volume MacBookPro internal appears to be OK.

I'm just surprise you say this used to work at all. You should never copy a file INTO another bootable disk, as it immediately messes up the permissions on that disk.
Sharing is fine for accessing files on another mac and copying files FROM that machine back on to the machine you're currently booted into. If you want to send a file to the other machine (the one you're not booted into) you should boot into that machine first, and then copy it FROM the first machine.
The other way to do it is to set up a shared Dropbox folder on each machine and place your files in there, which will update the files on the other machine when you boot into it.
Anything else is going to keep giving you permissions problems, I'm afraid.

Illustrator CS6 Repeatedly Corrupted Files?

hello --
thank you in advance for your time as i am quite in a predicament. i have lost 2 full days of work due to file corruption and i cannot isolate or fix what the problem is. here is how my files are set up:
i use multiple artboards (16-20)
i use graphs to simulate segments in a dashboard view (pie charts)
i use 2 font families
i have tried every solution under the sun so far:
reset preferences
saved recovery files
tried editing the postscript files to remove offending commands
saved as PDF, which worked, but the files are essentially unusable since in many separate files
any possible fix i found in this forum i could think of
after opening the file i get the error message, and if i open the file, most of the layers are gone and it stops with a "graph" object layer, which cannot be selected. it suggests to me that it might be something with the way i use them (i use several of them), that caused the issue. i have tried to isolate that element and it's occurrences in the postscript file, but probably not doing it right.
has anybody experienced such problems using pie charts in CS6. the last 2 files i worked on both used pie charts & both have become corrupted.
any help would be much appreciated!
thanks,
patrick.

Patrick,
Are you saving to own harddisk? If not, I believe you should.
It is always recommended here to open/save your documents from/to your own harddisk, then copy to external media/servers/whatever as backup.
You may be lucky (for a while), but the chances of file corruption and other unpleasantnesses are immensely greater when you use anything but the harddisk.
To rescue what may be rescued:
One thing often tried first is to create a new document and File>Place the corrupted one to see how much may be rescued that way (remember to tick Paste remembers Layers in the Layer palette flyout/dropdown first, and to untick it afterwards).
Here is a website where you can see whether it can rescue the file, and if it can, you may pay for a subscription to have it done,
http://www.recoverytoolbox.com/buy_illustrator.html
and another similar website,
http://markzware.com/adobe-software/fix-illustrator-file-unknown-error-occurred-pdf2dtp-fi le-recovery/
As far as I remember, the former is for Win and the latter for Mac.
Here are a few pages about struggling with it yourself:

Repeated corrupted files: implication?

Hi
I had trouble with corrupted fonts and now I have had to delete some caches from work. It seems that two files have recently become corrupted and messed up unrelated programs. Does this mean my had disk or computer is becoming unreliable? Is my computer about to die? Is it just a coincidence? Should I be more worried about North Korea?
My suystem is as follows
MacBook Pro
13 inch, Mid 2010
2.4 GHz Intel Core 2 Duo
4GB
10.8.3
One problem happened before I updated to 10.8 and one after.
Thanks!

IMac repeatedly corrupting external drive directories in sleep mode

When putting my iMac into sleep mode or when it goes into sleep mode after a period of inuse I keep getting the "improper eject" message. After waking the iMac I sometimes get the "disc not initialized" message and discover that the directory has been lost. It's happened to 4 different external drives in the space of a month.
The disks are connected via firewire 800. I have recently added a firewire hub but the problem was happening prior to and post this addition. I can't think of any other changes I've made to my set up that may be causing this behaviour. Previously I've had no problems of this nature in the 2 years since I purchased the iMac.
The drives run without this problem when connected to my MacBookPro.
Does anyone have any ideas or suggextions for running any diagnostic tests I coulod run?
Thanks in advance.

I have the same issue on my 2011 MBP. I have three FW800 drives daisy chained together. The first drive in the series disconnects when my computer goes to sleep and I get the error stating the drive wasn't dismounted properly. The other two drives stay connected fine. I don't have to close the lid, it will do this after the computer goes to sleep based on my power saving settings.
The drive that disconnects is a 500GB G-Drive. The second drive is a 1 TB Hitachi drive mounted in a IcyDock. The third drive is a 500GB G-Mini Drive.
I had the same three drives connected to my previous 2007 MBP and never had the issue. The issue started when I purchased my new MBP in July. My software is up to date and I'm use OS X Lion.

Time Machine corrupting file system

I've been using Time Machine on an external hard drive for a long time with success. Recently the volume got corrupted and I could not repair it from disk utility. After formatting the drive I did backups for a few more days and it happened again. I used diagnostic tools from the disk manufacturer and they did not indicate any physical failure in the equipment.
Has anyone had a similar experience?
Thanks in advance!

That misbehavior is typical of a failing disk, diagnostics or not. Replace it.

RAC using templates /u01 corrupt file system

Hi,
newbie to the forum - please be gentle ;o)
Trying to install RAC using virtualbox and templated. Get to the point of just before first boot interview when vnc'd into the virtual machines. But the boot fails with a corrupt /u01. ANyone had corrupt /u01 before ? How to stop it happening ? I tried to continue by using "fsck -a" but it would not allow automatic fix. So I tried manually going through each error ( but there are thousands ). Also tried taking /u01 out of fstab to get first interview. But then the installed failed after doing buildcluster.sh due to same issue ( corrupt /u01 ).
Have tried creating new VMs - always getting corrupt /u01.
Any thoughts / ideas welcome.
Thanks.

Arf,
I am new to RAC. I analyzed Alejandro's script. He is main connection is to the first instance; then through sql*plus, he gets connected to the second instance. he exits the second instance and starts with RMAN backup to the database . Therefore the backup to the database is done from the first instance.
I do not see where he setenv again to change to the second instance to run RMAN to backup the second instance. It looks to me that the backup is only done to the first instance, but not to the second instance. I may be wrong, but I do not see the second instance backup.
Kindly, I request your assistance on the steps/connection to backup the second instance. Thank you so much!! Terry

Can iMac not waking from sleep be caused be a corrupt file

I have had my 27" iMac from July of 2011 (running Montain Lion, 8 GB RAM, 2TB hardrive, 3.4 GHz,Intel i7) for over a year and a half and ever since I bought it, it has had a problem waking from sleep. I can hear the computer running, but when I click the mouse, keyboard, or power button, it stays asleep and I am forced to do a hard shut down. Apple has been trying to fix the issue, but to no success. They have replaced the hard drive, logic board, usb ports, RAM, mouse and keyboard, but it still happens. They finally threw in the towel and are replacing the machine. They offered to transfer all of our files (jpgs, mp3s, docs, videos, etc), but one thought occurred to me... what if the sleep issue is caused by a corrupt file? I highly doubt that is the case, but wonder if any of the experts out here would know better than I.
If we didin't have the data transfered, we would just keep it on an external hard drive instead. But, I would assume that it wouldn't matter if the files were on internal vs. external because either way, the computer would access the files. That being the case, if the sleep issue was caused by a corrupt file, the computer would still access it on the external and the sleep issue would resurface.
So, 2 questions:
Can a corrupt file cause the sleep issue?
If it is true that a corrupt file can cause the sleep issue, would it matter if the corrupt file was accessed from an external drive vs. internal drive?
Thanks so much!
Chris

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Please help! My Itunes says corrupt file and will not open (IMac 2010). I couldn't fix it by reinstalling so I moved it to trash. It will not delete from my trash as it is saying "Japanese.lproj" is in use. I can't delete or open to close it, what do I do

Please help!
My Itunes says there is a corrupt file and will not open (IMac 2010). I couldn't fix it by reinstalling ITunes so I moved ITunes to trash. It will not delete from my trash as it is saying "Japanese.lproj" is in use. I have never opened or used "Japanese.lproj". I can't delete ITunes or open ITunes to close the Japanese.lproj, what do I do? Thank you for any help you can provide..

It will not delete from my trash as it is saying "Japanese.lproj" is in use. I have never opened or used "Japanese.lproj".
Interesting. This sort of thing is more common on Windows systems. Taken at face value, one of the iTunes program files (one of the Japanese language resources) is damaged.
I'd try running your Disk Utility over your startup disk. Does it find/repair any damage? If so can you empty your trash and reinstall your iTunes successfully now?

Firefox corrupts windows file system

Since upgrading to Firefox 32.0, my Acronis Backup stops with the error message
"Backup of file or folder c:\Users\Robert\AppData\Local\Mozilla\Firefox\Profiles\<Firefox.Profile>\Cache" failed. File or folder does not exists."
The problem no longer occurs after running chkdsk which implies a file system corruption, but it re-occurs when opening and closing Firefox.
Note that I use hibernation (i.e. I open and close the browser, hibernate, wake up and then note the file system corruption)

Yes, I have checked that the folder is not explicitly specified. Also, after running chkdsk, the backup runs successfully, even if the folder does not exist.
I have run some more tests, and am now very confident that this is indeed a bug.
Reproduction:
1) Start & Close Firefox
2) Run Backup --> Error
3) Create an empty folder named "Cache"
4) Run Backup --> OK
5) Start & Close Firefox --> Folder "Cache" is renamed to "Cache.Trash<Number>"
6) Run Backup -> Error
repeat as desired
I have found a temporary fix: When I remove the delete permission on my manually created "Cache" folder, Firefox does create a "Cache.Trash<Number>" folder, but cannot delete the Cache folder. The backup will run in this case.

Oracle vm 3.1.1 server pool file system corruption

Hi
I have a small lab environment composed by 2 Oracle VM Servers and SAN access.
This morning somehow the OCFS2 Server Pool File System (the 12GB one) corrupted and the Server Pool seems dead. How can I recover from this error? I looked in the documentation and MOS but found nothing
Thank you

I know it would be a lot of work in such a scenerio. I don't know what you're using for storage but you could snapshot or replicate the pool storage to create a backup that can be restored.
I do wish they would let you select more than one VM guest in the VM Manager. Would be really nice to have such. Seems like it would be a rather easy feature to implement.

Hi there,
You're running an old version of Safari. Before troubleshooting, try updating it to the latest version: 6.0. You can do this by clicking the Apple logo in the top left, then clicking Software update.
You can also update to the latest version of OS X, 10.8 Mountain Lion, from the Mac App Store for $19.99, which will automatically install Safari 6 as well, but this isn't essential, only reccomended.
Thanks, let me know if the update helps,
Nathan
