Disk structure issue

I'm getting disk structure corrupted and unreadable when trying to update iOS or iTune sync

I've had experiences with node issues that would just never go away. What I did to fix it was to use Carbon Copy Cloner to clone my disk to a backup drive, reformatted my drive with Disk Utility, then cloned back the drive. Its a long process, but its the only thing that worked.

Significant Disk Structure Damage - Any Ideas?

I just suffered fairly catastrophic disk structure damage that is very to a similar situation I experienced back in January. I was running 2 Windows XP VMs via VMware Fusion that popped up error dialogs to the effect that they were having trouble with disk access. I wasn't actively working with the VMs at the time this happened, one I had just logged into, and the other had only Outlook and a proprietary messaging app running at the time. The Mac OS disk they were hosted on was still visible in Finder, including the top level directories. When clicking on the folder that contained the VMs, no icons were present. When viewing the same folder via the ls command in Terminal all of my VMs were present (at least their .vmwarevm directories showed up in the results of ls). I brought everything down as gracefully as I could think of under the circumstances (using Fusion' boot.sh --stop to bring it down), and a normal shutdown of the Mac that was uneventful. I cycled power on the External Firewire drive that hosts the VMs and then started the Mac back up.
Finder reported the external disk as unreadable and I chose to ignore that message, hoping to recover the contents of the disk. I ran Disk Warrior on the disk and it recovered the entire directory structure and all other files, but everything except the runtime lock files of the VMs were gone, no virutual disk files, no config files, no useable pieces of the VMs. The external disk is used primarily for hosting VMs. I do have a small number of files on it for archive purposes, but at the time this occurred the only user driven I/O was the running VMs. The system logs (attached) do indicate that Spotlight was having some issues accessing the disk as well.
I have my Fusion Preferences set to Optimize for Virtual Machine Disk Performance, which I believed to be the safer setting for Disk I/O given issues previously with the Optimize for Mac Application Performance. Is that understanding correct, or am I taking more disk integrity risk with this setting?
I'm attaching the Mac OS log & VMware Fusion log sections that document the issues with the disk. The particular disk in question worked flawlessly from when I purchased it in January 2008 to January 2009 (the last time I had an incident very similar to this), and then again from January 2009 until today. I recognize there may be some sort of intermittent issue with the disk, and the next few days or weeks will tell me if it is somehow failing.
I have posted a similar question on VMware's Fusion Forums, but wanted to solicit ideas from both camps. I had a full backup of both VMs such that I only lost yesterday's work, the biggest loss is to my confidence of the safety of my current configuration. FYI, I have a late 2007 MacBook Pro, 2.6 GHz, 4 GB RAM, Leopard 10.5.7, Fusion 2.0.4, both XP VMs are SP3 and I keep up with patches. Anyone able to glean what might have happened from the referenced logs I would appreciate your ideas.

[Fusion Log of Failure|http://www.gmginnovators.org/files/shared/MBPDisk-VMwareFailLog.txt]

I think the net result is the same for January and now. In January I believe I had one of two VMs running, the whole disk took a hit and Finder wanted to initialize it on restart. At that time Disk Warrior recovered everything but the VM which was running, in that case I don't think it even recovered the folder the broken VM was in, but not positive about that. This time both VMs were running and all of their files were lost. To Mac OS and disk warrior the VM virtual disk is just a collection of files (2 Gig each) that are admittedly probably pretty busy (they would be subject to whatever I/O a typical Windows machine does in the background).
The same disk has worked fine all day since the recovery which causes me to lean more towards a software issue than a hardware issue with the drive itself. I also can not rule out something with the Firewire interface or controller, but so far this is a really low occurring problem. Very dramatic when it does occur though.

Org structure issue

Hi,
I have a question related to an org structure issue. Let me explain by taking an example:
The Org set up we have goes like this, let A1 be the VP of a particular division, he has a director B1 reporting to him. B1 has four different employees C1, C2, C3 and C4 reporting to her. The interesting part here is, C1 and C2 belong to a different cost center (say CC1) and C3, C4 belong to a different one (CC2). Both CC1 and CC2 are managed by B1. The tricky part is CC1 comes under the VP 'A1' while CC2 does not have any supervisior above. B1 is the final supervisor.
The problem is, when I run the Org report to find all the employees coming under A1, C3 and C4 also show up. How to correct this?
In our system, the org structure is driven by position of the employee and not by the cost center. However we have an relationship record (A011) in HRP1001 between the Org unit of the employee and the cost center but it does not serve the purpose because B1 is placed in one cost center CC1 and manages the other cost center CC2 too. Since she can be in one cost center at a time say CC1 there is no record pertaining to CC2 for her.
How to resolve this? what kind of config change needs to done?
Any leads or suggestion would be helpful.
Thanks in advance,
SG

Hi,
You can define your organization structure except the cases you have exceptional .
For the exceptional Objects create them in Expert mode and maintain infotype 1001 depending upon the requirement.

Disk Space Issues

Does anyone out there have best practice insights on how to deal with disk space issues on the database server? Can we copy the files onto different drives and then rename the drives? Will everything with the BPC application sync up again?
Is there anything tricky in dealing with this issue?
Thank you,
Grant

Hi Grant,
I once had to move the SQL database files from one drive to another. The only thing that I did was 'Detach the SQL database' in Enterprise Manager, move the files and 'Attach these files again. Everything else was automatically changed.
You can attach/detach using sql statements or using the graphicall user interface from SQL.

SCCM 2012 R2 DP - Reserve Disk Space issue

Hi Team,
Issue with SCCM 2012 DP. Reserve Disk space issue.
During DP installation I have given 100000 MB as Reserve disk space, now my DP Share drive reached below 97 GB of free space, now I’m unable to distribute packages to the DP.
Below is the error Message in Smsdpprov.log
Failed to find space for 105874160 bytes.
Solution tried:
Tried changing the reserve disk space value in Registry (HKLM- Software – Microsoft – SMS- DP- ReservedDiskSpace),
But the value is getting auto reset to old value after a restart.
Is there any way where I could change the Reserve disk space without reinstalling the DP Role?

Hi,
>>Is there any way where I could change the Reserve disk space without reinstalling the DP Role?
We need to edit the reserved free space in SQL database. But this is not supported by Microsoft.
Steps:
1) Run SQL query:
select SCR.ID, SCR.Name,SC.NalPath, SCR.Value3 from sc_sysresuse_property SCR join sc_sysresuse SC on SCR.SysResUseID = SC.ID where SCR.name = 'MinFreeSpace' and SC.NALPath like '%<DP_Name>%' and SC.RoleTypeID = 3
Note: you need to replace the <DP_Name> with your actual remote DP server name.
2) Use the returned ID in step 1). Run the below query to update the 'MinFreeSpace' value.
update sc_sysresuse_property set value3 = 'set desired value in MB' where name = 'MinFreeSpace' and ID = 'ID retained in previous select query'
Example:
update sc_sysresuse_property set value3 =20480 where name = 'MinFreeSpace' and ID = 75340198761234567
3) In the next package content update cycle, the reserveddiskspace registry value (under HKLM\software\Microsoft\SMS\DP) will be changed
to 20480.
Or you can restart the SMS_SITE_Component_Manager service on SCCM site server
to update the “reserved free space” value on remote DP.

Joyce

Restore Oracle with brtools to a Windows server with different disk structure

Hello gurus,
Is it possible to restore Oracle to a Windows machine that has different disk structure than a source machine?
E.g. source machine had disks C:, D:, E: (on which Oracle data files were distributed), but a target machine has only disk C:
Database is backuped with brtools.

Hi
I did some mass changes using a script... to be honest I'm not sure if I did it to restore FROM a different location, or TO a different location.
You could also use Brrestore option -m|-mode to restore the datafiles to a new location.
Check online help -m|-mode - SAP Database Guide: Oracle (BC-DB-ORA-DBA) - SAP Library
For instance the here under command will restore datafiles #10 to #20 to the /tmp directory
brrestore -u / -b beokfyeu.pnd -c -m 10-20=/tmp
You could find datafile ID by querying view dba_data_files
select FILE_ID, FILE_NAME, TABLESPACE_NAME from DBA_DATA_FILES;
Regards

Disk Repair Issue on iMac G4 Flat-Panel

A few months back, I started up my computer and received the endless loading pinwheel, with no progress since. After visiting this site and getting some info, I was able to discover I had a number of catalog and directory issues which I was told could really only be resolved by purchasing Disk Warrior.
I bought the program and booted it up from CD. It took awhile, but finally it told me it was able to repair the issues it found. I got to the screen that would allow me to Graph or Rebuild the drive. At this point, it told me the disk did not appear on the desktop. I couldn't select any options and I was stuck. So, at that point I let it run for a couple of days and nothing.
From there, I ran TechTool Pro from my Apple Care CD, I ran the Hardware Test CD, and I ran Disk Utility. All stated that there were no physical issues with my drive.
I tried DW again. I can load from CD, agree to the license, and just as it starts the process of "Scanning for disks..." it COMPLETELY freezes, stationary beachball and all.
I've spoken with the DW people and they have concluded that the hard drive probably has physical issues in addition to the directory issues. But, I have run 3 different utilities that all say its fine, and I didn't have any physical issues prior to purchasing Disk Warrior. The only alternative they have given me is to boot from an alternate startup disk (I have no firewire capabilities or external drive) or in target disk mode (again, I don't have another Mac lying around).
So now I am stuck with this new program I can't use. I can't boot the computer normally because of the issues I had which led me to purchase DW. When I try to reinstall the OS, I don't have a disk available to load it to (only the CD from the install disk shows up).
Any thoughts? I swear I have tried everything!

Thanks, but it looks like I have a few more hurdles to overcome before ugrading
As suggested by the Mac Tech from the store, I was able to successfully reinstall OSX on the drive that he magically partitioned and got working for me. I had no issues there.
After the install, I ran Disk Warrior from the CD and inspected/repaired my directory. I got a clean report on the repair. I also ran the hardware test from DW and it stated that my HD was functioning properly. Even the S.M.A.R.T. diagnostic said it was fine. To be safe, I also checked the files and folders to make sure there were no issues there. So essentially I ran all the tests that DW offers and everything came back fine.
However, when I boot up normally, I still get the flashing Finder/Question Mark folder icon that continues forever and never boots. I've searched the forums and tried all the options listed here: http://docs.info.apple.com/article.html?artnum=58042
Nothing has worked. The only other suggestions I have seen indicate hard drive failure and the need for replacement. But, I JUST ran the diagnostic on my hard drive and it came back without errors. Unless the diagnostics are wrong, I would assume my hard drive is fine.
The only thing I can thing of (again) is that my disk is not mounted on the desktop and its not being recognized at startup. It should be absolutely clean considering I reinstalled the OS and rebuilt the directory with DW.
Any ideas?

Report structure issue

EPM 10 SP15
I have a requirement to build a asymmetric column axis and dynamic row expansion input form to be done. If i can do this, that would avoid unnecessary building the same structure with 7 different reports to construct the asymmetric columns. But i am facing an issue that the rows not expanding.
Based on Vadim static report blog i am convinced that we can have a static asymmetric col axis and have a dynamic row axis but looks like in my report build it is not expanding on the row.
Here is what i did
1) Build the column axis as below resulting in EPMOlapMemberO cells referring to other excel cells. Basically I wanted to show i have a asymmetric column axis need.
ACTUAL        PLAN           PLAN            ACTUAL
PROD1         PROD2        PROD1          PROD3
2013.JAN      2013.FEB     2013.JAN       2014.JAN
2) Row axis should expand based on parent node like
Customer Group
---Customer 1
---Customer 2
---Customer 3
3) Of course i need some page axis overrides
What i did:
By enabling member recognition i created the col axis cells referring to the cells i already constructed manually
I manually entered a dummy member in row axis cell with member recognition on
It automatically recognized col and rows and created a default report
So far so good.
Now i went to row axis selection and made the member selection to Customer Group (member & children selection).
Then i refreshed the report assuming it would expand on row but it didn't do anything
Am i doing something wrong? Is it possible to have a static col axis with dynamic row axis?
I also want to ask if this is a safe approach to build a report with static col axis and dynamic row axis. Would it prevent me from inserting local members in col axis later?
Any help is appreciated..
~Dilkins

You are doing something incorrectly. If you have row axis Customer member definition as:
Context (Member and Descendants)
Then if you change context to some parent and refresh - your row axis will be expanded to Member and Descendants of the context parent.
You can also use =EPMDimensionOverride for Customer.
"If I follow this construction, can I add local members in between the columns at later time?" - yes, you can insert local member columns.
"I plan to do PageAxis override" - what do you mean by override? EPMDimensionOverride is applicable only for row and column dimensions! You can use Excel formulas as it's described in the blog.

Interesting Twist to the disk failed issue.

Hello,
I have read the article for the following error:
"Attempting to copy to the disk <iPod name> failed. The disk could not be read from or written to."
However, nothing is working. The interesting part is that my iPod Mini will sync songs, just not the playlists. I have no playlists except for the one that's created when the ipod was built.
iPod Mini Windows XP

Hi Jeff,
Thank you for your help. Your last suggestion helped me get to the answer. Basically I had two issues going on. First, when you mentioned the drive letter, I noticed that My Computer didn't list my iPod as a drive letter. That let me to the Microsoft fix that's outlined in the 5 R's that Apple suggest check. I was lucky to get the fix quickly.
The second issue was that iTunes was losing the preferences that I set for my music location. I have a server where all the music is stored (so when I rebuild a system, I don't have to reinstall all the music, etc.). For some reason, iTunes lost the settings in the middle of all of this and it was saving my music that should have been saved to my iPod to my C: Drive. When I changed the network drive letter of my music (as you suggested) everything fell into place.
Thanks again!!

Disk Utility Issues Wait to Install Leopard

Dear fellow Mac users,
Rather than a question, this is a recommendation to those who are wondering whether to install Leopard now or to wait until it gets really stable.
My experience in installing Leopard has not been positive and I chose to revert to Tiger. After discovering several issues and going to the "Genius Bar" of the local Apple Store, I fortunately have been able to restore all my previous settings.
The loss has been mostly time and money, and they frightened me up suggesting that I had to change my hard drive. For those who might experience similar problems, let me provide some details.
1. Installation of Leopard
After carefully making a bootable backup of my HD on an external drive, I installed Leopard choosing the Option "Erase and install." This occurred without visible glitch. After updating the system to its latest version, I migrated all my data and settings. The result was an incredibly slow system, completely useless. It cannot have been the results of my settings, because I also created a "clean" account called "Maintenance," with the same results. On the recommendation of the "Apple Genius" I also added 1 GB of memory, getting a total of 1.5 GB of RAM installed to the cost of $150. It did NOT improve the situation.
2. Disk Utility
Because I suspected problems with privileges, I tried to run the Disk Utility. The result was an endless spinning wheel. After waiting several hours, I had to force quit the application. Tried to run it from the install DVD of Leopard, with the same results. People at the Genius Bar also tried their disk utility after booting from an external drive, without any success. They diagnosed a probable failure of the hard drive and recommended that I replace it. Fortunately, I didn't trust this groundless recommendation and made a last attempt by erasing Leopard and reinstalling Tiger. Now it runs just fine, and there is not the slightest mechanical problem. Apparently, and I only discovered this today, the whole disk check procedure changed with Mac OS 10.5, and at this stage it is a complete mess, with enough bugs in Disk Utility to keep the developers busy for a couple of months. I came across discussions of this on the Mac FixIt Website.
Thus, my recommendation at this stage is that if you have Mac OS 10.4.11 running fine you JUST STICK WITH IT and be patient for a few more months. Upgrading at this stage amounts to loosing time, energy, and money. Of course, I am sure that Mac OS 10.5 has many promising features and look forward to using it in the future, but not now. I would be happy to hear contradictory opinions, if any.
Best wishes for patience.

Nerowolfe,
I have installed Leopard and have had nothing but problems as well. Perhaps you can help me. I am ready to roll back to Tiger. These are just a few:
1. I cannot mount my external firewire drives. I have separately tested each and they work fine, I booted with the Tiger disk and they mounted fine, I reset the firewire port and when I connected them they mounted on my desktop, but not in the finder window and when I tried to open one, it just hung. I have been unsuccessful after many attempts to mount one of them with Leopard.
2. I appear to get random hangs. I have a 160GB hard drive and 2GB memory. I have 42 GB space left on the hard drive....yet I continue to have random hangs, especially when I try to open disk utility
3. Spotlight just does not work, period
4. I keep finding locked folders. Right now my CS3 is locked and even after going into get info and unlocking it, it just locks back and I am unable to open the application. I am a photographer and have been unable to do any work for the past 2 weeks while I am messing around with my computer. Now I have Christmas photos to sort and can't access the photos on the external drives or even open CS3
I have searched the forums, tried many of the recommendations, but nothing is working for me....perhaps since you have been successful you could give me a hand with these issues.
I wait for help.......
Other than that, how do I uninstall Leopard and reinstall Tiger????

Shouldn't Disk Utility be able to repair all disk permission issues?

I am having some performance degradation issues on my 20 inch, 2.16 GHz Intel iMac so I tried to run repair disk permissions (after getting a clean bill of health from Verify Disk). The first two times I ran it, it must have made over 1000 repairs. I kept running it and it eventually got the number down to 29 to 30 lines in the repair log - but not without doing some peculiar things in the process. Subsequent runnings of Repair Disk Permissions report the same repairs - line for line - and I've run it at least 8 times now.
In the good old days, running Repair Disk Permissions would eventually give a clean bill of health. What gives?
Just for the fun of it, I ran Repair Disk Permissions on my brand new (relatively) 11" MacBook Pro. The log for the first run was at least a couple of hundred lines. The log for the second run was at least TWICE as long. I ran it two more times and - guess what - the repair log was almost identical to the log on my iMac, line for line. And additional runnings of Repair Disk Permissions didn't produce a different result.
I hope someone from Apple reads these posts because when things don't go right with their products and the tools they provide - more and more - don't work as expected, we have nowhere to turn to but to Apple to find a solution.
In the meantime, I would welcome any suggestions on what this all means.
Note: Both computer are running Snow leopard. The iMac has been updates to 10.6.8 and the latest Java update has been installed. The MacBook Pro is running 10.6.7 and has not had its Java updated. Both computers have 250 GB drives with at least 68 GB unused. The MB Pro has 4GB of RAM and the iMac 3GB.

Hate to burst your bubble but Apple does read these forums for problems.
Now that the others have replied that repairing permission is not the way to fix performance problems.
How much free space do you have on your system disk?
How large is your Desktop folder?
Either insufficient free space or an overly large Desktop folder can impact performance.

Repair Disk Permissions Issues

I'm not sure I am posting this in the correct community but here goes . . .
I have a 17" Macbook Pro running the latest version of Snow Leopard. It is almost 2 years old and I have 4 gb RAM.
Recently, it seems to be slowing down and I have to run repair disk permissions 2-3 times a week to recoup a little speed. I also delete my Firefox cache regularly to try to gain a little there. I do make a few videos in iMovie and initially I thought that was the problem but this week I have not really worked in iMovie much and it is still slow. There seems to be some issues in the log of the repair permissions. I hope they show in this image. I don't know what these mean or how to fix them. It is the "permissions differ" entries I am confused about.

You can ignore those permissions per support article
http://support.apple.com/kb/TA21090
Since you brought up iMove, I suspect your storage is nearly full as this most certainly causes the computer to slow down. video files are the biggest culprit.
Look in your Activity Monitor and reduce the drive space by copying to a external, Disk Utility HFS+ formatted external powered drive of unnecessary files so your boot drive is ideally below 50% filled (yea I know but the computer slows down after that) and not more than 75% filled.
Once you have done that. Get another newer external powered HFS drive and download the free Carbon Copy Cloner and clone the internal drive to the external.
Hold option and boot off the external clone, test it out then use Disk Utility to erase the internal and then reverse clone the external onto the internal, this will defragment and optimize your drive so the OS and programs are on the fast part of the drive, not the slow parts.
Reboot into the internal and run off of the free OnyX's maintainence and cleaning aspects and reboot.
http://www.titanium.free.fr/
Sir speedy machine here we come!
Now of course you may have other issues that could be causing your slow down, like not enough RAM or some sort of failed process or leftover program, tweaks or simply a slow Internet.
You can opt to simply reinstall OS X 10.6 ( by holding c and booting off the installer disk ) over your installed version (doesn't touch files or programs) then immediatly Software Updating until clear, that will clean anything hanging out in OS X.
If you still have slowdowns, then it's in what geeks call "User land" basically something installed outside of root, like a program or only runs in user, not in OS X.
For that you need to create a new user, transfer your files via the Shared Drop and wean yourself off the old user and finally delete it. Also install all new versions of your third party programs removing the originals first.
That should do it.

Disk repair issues on my mac pro. grrr.

I have a Mac Pro and am trying to install a 2 TB Hitachi hard drive. I put it in the second slot and when I start my computer it says that it doesn't recognize the disk. When I try to initialize the disk on disk utilities the repair disk and verify disk buttons are greyed out. Where do I go from here? I need the extra space pronto. :-) Thank you.

A new drive comes from the factory unformatted, or formatted for Windows, possibly in a read-only format.
You cannot "Repair" it into existence, you will need to use Partition tab to create a brand new Partition Table and related data structures. Do not use "as currently implemented", deliberately choose "One partition" from the menus. Make certain you are getting GUID Partition Table and Mac OS X Extended, (journaled) Volume.
If the drive is over 2.2TB, stay away from the ERASE tab, as there are bugs in 10.8.4 and later ERASE that have not been resolved at this writing.

Disk Repair Issue

Hey guys,
I'm trying to figure out if I need my start up disk to fix my following problem or not, or if I can fix it regardless.
So, I was running OnyX today to clean out my caches and history and just run general maintenance on my MBP. It asked me to verify S.M.A.R.T. status and so I agree to such task and it tells me my disk needs to be repaired. I open up Disk Utility and when I hit verify disk, at the end of the procedure, errors out and tells me "The underlying task reported failure on exit".
Anyone have any ideas? I want to prevent any sort of issues later on down the road and I don't have my disk on me at college right now. Thanks in advance!

Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
