Failed volume structures test using TechTool Pro

Tech tool pro not recognizing main hard drive, only the eDrive! How can I initialize the corrupt main drive?

No only the internal drive I installed in Bay 2 shows up in D.Utility, or I could erase the disk1s2 from there. Checking Sys. Profiler,and comparing the data there to original hardware overview, the only thing different is the Boot ROM version, but that may be due to a system upgrade fom Tiger to Snow Leopard??

Using techtool pro found problem with "volume structure". What to do?

Using techtool pro found problem with "volume structure" and this was not fixed by TECHTOOL PRO. What do you suggest I do?

I would boot from my gray install disk (put the disk in the drive and restart holding down the C key). Then choose Utilities and run Disk Utility and click Repair Disk. As always, be sure you have a back up of your data first.

Failed Volume Structure on TechTool..

I was doing the tests on TechTool and failed the volume structure test. It didn't tell me why and when I tried to repair it, it didn't allow me to. Is this something I should worry about. I just got the computer and don't want problems right away.

I hope you aren't using the PowerPC version 4.1.x because it will not work on Intel Macs.
MicroMat has a beta of their universal binary 4.5 available. I would, however, recommend using the Disk Utility that came on your MBP.

10.5.8 update corrupted the Volume Structure of my MacBook Pro and iMac

After installing the 10.5.8 update on my Macbook Pro AND my iMac, BOTH computers refuse to boot up. If I boot from a TechTool Deluxe DVD and run the system scan, It fails both the Directory Scan and the Volume Structure test. The only common application on these computers is the Fusion PC emulator. I was reading that the newest update fixed problems with this application. PLEASE HELP!!!

Some general advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site.
The Combo updater of Leopard 10.5.8 can be found here:
http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 4.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
If you are updating Safari (or just have):
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very first thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
• /Library/InputManagers
• ~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).

Using Techtool Pro 5

Hi, I just finished setting up my new Mac Pro. Pretty amazing upgrade from my old G5 dual 2.0! I was wondering if anyone has advice for using techtool pro to repair,defragment and rebuild drives from time to time. I certainly used it on my old power mac and it was helpful in optimizing performance.
Thanks in advance.
Howard

stuck in an elevator with an insurance agent.
I am in fact the designated elevator emergency operator at my Insurance office...
I figured out one mystery, why I couldn't find the same options as before. I had been using TTP 4.
There is a host of clear cut specified options for creating ones own set of tests in TTP4, that in TTP5 may, I don't know yet, be only possible by clicking the "next" button, which seems to be the one on the right.
But the commands begin very slowly it seems. One click and wait half a minute or so might do it. I'm getting too annoyed to tell.
If anyone can tell me where the old interface like structure is on TTP5, please do.

Is there such a thing as a Volume Structure Test for my Imac?

When I purchased my Imac-Intel in 2009, a program came with it called "Techtool Deluxe-ver. 3.1.3" by Micromat,Inc. It tests all the hardware features on my harddrive with other diagnostics. One test is the "Volume Structure Test" which is the only test my Imac failed to pass. Is this serious enough that I should do something, and if so, do what? Is it an issue I can resolve or would I need an Apple Techy? This program is out of circulation now and a replacement in its place that needs to be purchased from Micromat (which I have not done). Appreciate your thoughts, anyone...
Vfp

If your computer is working OK then I'd ignore it. If you suspect a hardware problem the computer came with Apple Hardware Test, in order to get the most comprehensive results from AHT it's best to run in Extended Mode.

Volume rebuild using TechTool Pro 5 - How long??

We put the OS X 10.5 install dvd in our Macbook with the intent to edit the administrator password and instead triggered what our Macbook thought was some kind of upgrade. We were afraid to cancel it, but about a minute in the "upgrade" ended up failing. We lost our ability to boot to the desktop and so we took it in to the Apple Store where they advised us that the node structure became invalid. They told us to either get Diskwarrior or TechTool Pro. We opted for the latter.
We've been doing a volume rebuild now for the last 27 hours. Is this normal?? We did not have an external drive, but there's no indication that this is required. In further searching, we noticed that it's recommended to have one, but we don't. The program has been sitting at "repairing directory structure" and occasionally the dvd drive spins. There's no progress bar, so we don't know what is going on. Does anyone have experience with this who can shed some light on what's going on??
Thanks!

How to fix failed volume structure

I ran tech tool deluxe and got the diagnostic that the volume structure failed the test. Tech Tool Deluxe doesn't offer an option to "fix" this problem.

Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...
http://docs.info.apple.com/article.html?artnum=106214
Just recently I ran into a problem when I tried to Verify my hard disk and when it tried to verify the catalog, it responded "Invalid sibling link." Repair Disk didn't work. I searched the web and Apple's site, and couldn't find anything useful except to buy DiskWarrior or reformat the drive. Knowing that OS X is built on Unix gave me a few clues on how to proceed. The solution is pretty simple:
Boot off the OS X CD (reboot, hold C while booting).
The installer will load up, go to Utilities in the menu and run Terminal.
Type df and look for the drive that has your Mac system mounted---you'll have to unmount this. On my MacBook Pro, it was /dev/disk0s2.
Type umount /dev/disk0s2, replacing disk0s2 with whatever disk your OS lives on.
Type fsck_hfs -r /dev/disk0s2. If you umounted the wrong thing, it will complain that you can't repair a mounted drive. Go back and umount the right thing and repeat this step.
Just for fun, you might want to run another fsck_hfs on your disk (use the -f option because your drive is probably journaled). Hope this helps someone so they don't buy a program that's going to do pretty much what we did with fsck_hfs, and so they don't waste time searching for an answer to no avail. By the way, TechTool Deluxe (3.1.1) didn't find the Catalog problem for some reason (you'll have this on a CD if you have AppleCare), which is why I resorted to fsck.

Your best bet is DiskWarrior, you need the CD/DVD though.

Failed volume structure on tech tool deluxe

i tested my mac book pro with tech tool delux and the volume structure failed. what should i do? i don't have a way to back up my files right now.... my volume sometimes takes a few seconds to work when i play music. is this a related problem?

hi tcbc59 - Welcome to Apple Discussions!
your hard drive is in bad shape..... playing music uses your hard drive so, yes, that can certainly be related....
you need to try to back-up whatever you can. can you not go buy a blank DVD and burn a disk using your superdrive?
(i don't use tech tool deluxe) have to tried to repair the drive using that app?
if not, Diskwarrior can probably fix the problem(s).
if TT and DW cannot fix it, then you're looking at reinitializing your hard drive and reinstalling everything. sometimes this is all one can do....
but again, back-up whatever you can before doing anything else.... post back if none of this helped. good luck! cheers

Tech Tool Deluxe Volume Structure test query

Hi,
Sorry if this is elsewhere, but my searches have not supplied a definitive answer.
As part of my regular maintenance routine on my iMac (mid 2010 i7 quad core) that I purchased just before Christmas, I have run the AppleCare Tech Tool Deluxe scans at regular monthly intervals with no problems, until about a month ago.
When the program does it's stuff, all tests pass, except the volume structure one (in the window showing the image of the volume structure, it says fail! above the "icon"). The final report that Tech Tool Deluxe comes out with says everything has passed. What's going on?
Because of this, I''ve also done a surface scan in the program and it was OK, as was verifying the disk in Disk Utility from the Snow Leopard DVD. I've repaired permissions and even reformatted the Macintosh HD and done a complete reinstall of the OS (not from backup), all of which come up with the same result in Tech Tool Deluxe - volume structure fails, but final report passes.
The version of Tech Tool Deluxe I have installed from the AppleCare disc is 3.1.3, which according to Micromat is the current one, but this is from 2009.
So my question is this:
Has the updated Snow Leopard (10.6.6) changed it's volume structure slightly meaning that Tech Tool Deluxe thinks there's a problem as it's scanning, but then ignores it for the final report, or is my HDD failing?
I've not noticed any issues whatsoever with the iMac and I have both Time Machine and bootable SuperDuper backups, so I'm not worried about my data.
Would you guys recommend ignoring it for now, or should I get Diskwarrior to check it out further?
Thanks for any help, or light that can be shed on this issue.

Hi Den,
Thanks for this, I emailed them and they are giving the usual story of "this product was developed for Apple, so you'll need to speak to them".
I've bit the bullet and purchased DiskWarrior 4.3 and by installing it onto my SuperDuper backup drive, I was able to check out the iMac's internal HD.
DiskWarrior was able to find errors in file structure and permissions etc (it didn't give details) and was able to repair them. After rebooting into the internal HDD, I ran TechTool Deluxe 3.1.3 again, and this time it said that it failed the volume structure during the test and then in the final report. It tried to get me to download the repair version of the software, but the web page that opened had nothing to do with TechTool's download. As a little self test, I ignored it and ran the test again. This time, it failed during the test (as normal) and then said that it passed in the final report.
I have therefore come to the conclusion that if Disk Utility AND DiskWarrior say that it's fine, then the issue must be with TechTool Deluxe. At least it doesn't seem to be an issue with the actual drive.
I admit that I was getting suspicious of TechTool when a fresh install on a reformatted HDD said that the volume structure failed and then passed. There must be something different about the current version of Snow Leopard comared to that at the time of release of version 3.1.3 of Tech Tool Deluxe.
Thanks for all your help guys.
Obviously, if someone can prove me wrong, that would help me ascertain as to what is going on.

Volume Structure Failed

I ran TechTools on a PowerMac (Dual 2.0ghz G5) that has many crashes and the "Volume Structure" test failed. Does this mean the HD needs to be replaced, or will reformatting the HD fix this problem?
Thanks

I do not use this Mac myself- another member of our design staff does- and she seems to only have this propblem when using Illustrator (CS2).
There are some (older) threads on how we ran into trouble early on with combination of plug-ins, PPC apps, and running Ill and CS2 together.
A lean mean system with 4GB RAM helps. And don't import from G4/5 PPC apps, those have to be reinstalled.
I would run Applejack + Memtest. TechTools Deluxe latest may be free and add more, but DW4 should be indispensable to your "arsenal" of utilities - a must have.
If not a new drive, every drive needs to have two backups, consider that a minimum "rotating sets" AND a solid system image, no extras or frills.
Catching errors immediately and not rebooting etc to avoid one error on top of another is essential, to catch it early. Install Applejack and have people run that immediately, and follow up with a SAFE BOOT.
If someone needs to work, with an image of the system that everyone needs, it would be easy to pull a drive for testing and repair, reimaging, and try to keep any and all data on a separate drive that is frequently backed up.

Is TechTools Pro worth the $$$

Hi,
I was just wondeing if anyone here has used TechTools Pro and if they felt it was a good utility to have and worth the $$$?

First would be extra drive and Disk Warrior 4 which are essential. I can't say that I've needed TTP4 in all the years of use and buying etc. though. Intech SpeedTools has some goodies that no one else seems to have though. And then a good backup program.

IMac i7 and TechTool Pro

I have TechTool Pro 4.5.1 on my iMac i7 (late 2009). I need to update to 4.5.2 or 4.5.3 in order to use TechTool Pro but Micromat says that I cannot bootup on the latest update because they still need Apple's start up files for the iMac i7. What are my options? Also, I have TechTool Deluxe 3.1.3 DVD but cannot get it to boot up.
Thanks for helping.

I do not own TT Pro, but checked their website and it seems that 5.07 is indeed for Snow Leopard:
http://www.micromat.com/index.php?page=shop.productdetails&flypage=flypage-ask.tpl&product_id=31&category_id=6&option=comvirtuemart&Itemid=80
You said you got the DW updated - I would simply install that on your internal and then create a bootable clone on an external drive (or, if you have a recent clone, just install it on your external). In any case, it is much easier to restart from your external and then run DW from there on your internal than actually booting from DW. And the result is the same: you do not have to be booted from DW, you just need to be booted from a drive other than the one you want it to work on.
Since I don't have TT Pro, I can't speak for that process, but can't see why it should work the same way (install on a bootable clone and run it from there).
Which brings up the question: you do have a bootable clone?? If not, you should have some sort of backup before running either of those apps just in case.

"Volume Structure Failed" in TechTool Deluxe

I tried to run Disk Utility on my laptop last night and it said that it "stopped reapiring "XXX" because the following error was encountered. The underlying task reported failure on exit (-9972)" It said there was an invalid catalog record type and volume check failed.
I then ran the lastest update of the TechTool Deluxe CD. Everything passed except the Volume Structure.
There were some "used nodes" and "free nodes" that differed--those numbers showed up in green as "favorable changes". "Leaf Record Count" showed up in red as an "unusual change". When I go to repair, it says that "unusual values in the volume structure have been dectected. Before repairing the volume structure, it is suggested that you back up your data. FAILURE TO BACKUP YOUR DATA MAY RESULT IN PERMANENT LOSS OF DATA!".
I do have a Retrospect Backup on my external drive, but I'm still a little nervous about clicking the "repair" button. How likely is data loss with this particular error that it's trying to repair?
I'd like to call Apple Support (I'm still under AppleCare for another week or so), but I'm not sure if they have Saturday hours.

Okay, here's what I ended up doing. I did end up calling Applecare Tech support, but mostly only to inquire about potential coverage if I needed it--since I was one week away from the expiration of Applecare. They opened a "case" for me and Applecare would remain in effect for 30 from the opening of the case. This was good news.
I tried using Disk Utility to repair the problem but it wouldn't work. I had repaired permissions and attempted to run “Check and Repair Disk”. Disk Utility said that it “stopped repairing ‘xxx’ because the following error was encountered. The underlying task reported failure on exit (-9972)”. It then said that there was an invalid catalog record type-volume check failed-volume was not repaired.
A friend of mine has DiskWarrior for Panther so we were going to try that before trying the TechTools Deluxe CD that I had just updated from the Apple site.
Went over today to do that. Unfortunately, we couldn't get the computer to boot up with the DW disk. It would boot up with the Install disc & TTD, but not DW. We tried booting with the option key. It did show that we could boot from "utility CD", but the minute we hit the arrow key after selecting it, we got a circle with a slash through it. We called DW support and they said that my computer was newer than the CD. This was strange since my friend's larger G4 Powerbook was only a couple of weeks older than mine and DW works fine on hers.
Anyway, we ran TTD and let it repair. Ran DU again and it still showed a problem that it could not repair. Ran it again--same thing. Ran TTD again--just to test. It showed that there was nothing that needed repairing. Ran DU yet again--3rd time for the afternoon. Did repair permissions first, then Repair Disk. Strangely enough, now it said the volume was fine and needed no repairing.
So, at least for the moment, things seem okay. Not sure exactly which step worked or if it was just a combination, but I'm just happy that it finally passed DU check.
I will continue to monitor for the next few weeks.

TechTool Delux - VRAM Failed and Volume Structure Failed

So I ran TechTool Delux today.. my VRAM failed, as well as my Volume structure.
Now, it says that I should quit all apps, restart, check recently added hardware for proper installation, run the computer from another volume (if available), reinstall the OS, and finally contact applecare.
now, is it really necessary to reinstall the OS? i'm not even sure if I could, i'm not experienced with reinstalling an OS.
as for the Volume structure fail, it asks me to run techtool on boot, which is what i'm about to do.
anybody have experience with these fails? any help is appreciated.

When VRAM fails on a Powerbook, it means the logicboard needs replacement as the graphics chip is usually on the logicboard.
Volume structure failure may indicate a hard drive dying or simply a damaged directory. If your data isn't backed up, I'd get Prosoft Data Rescue and external hard drive to attempt to recover data from the drive. If your data is backed up, I'd get Alsoft Disk Warrior to attempt to repair the directory. To learn how to backup your data, see my FAQ*:
http://www.macmaps.com/backup.html
* Links to my pages may give me compensation.
