Tech-tool/volume

My macpro is running slow ever since I installed leopard! I checked HD w/tech-tool and was told to download the disk.
Ran disk at which point it showed discrepancies in catalogue B info and catalogue B extents. I then ran repair, at which it showed no problems.
Still slow, for a few days tech tooled again /Dev/disk1s2 came up, followed instructions to resolve those same problems as on main disk.
Still shows volume structure failed!
any help would be appreciated
Thanks Gary

Problem solved thanks to Klaus1! she runs like new now.
If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
Once that is complete reboot again from your usual start-up disk.

  • Hung during Tech Tool Pro volume rebuild- what to do?

    Working on my ex's messed up 2007 MacBook 2.2ghz OS 10.5.8.
    Extreme heat problems, was hanging a lot, and Disk First Aid failed immediately with volume errors. With some diffculty, i got his critical files backed up to an external drive (he had no backup... i have no comment) and booted it with Tech Tool Pro 5 -retail DVD, not the applecare version- with OS 10.5.7 and it also immediately found trouble with the disk directory, tho the SMART parameters were all PASS except for internal temperature (which has been high enuf to warp the bottom of the case).
    But when i clicked Run Volume Rebuild, it hung in Acquiring Directory Structures. TTP's Elapsed Time clock stopped at 07:18... an hour ago. Fan is running like crazy.
    does this indicate what i think it might... a non-repairable hard drive?
    meanwhile, how do i get out of the TTP volume repair hang, pref without further damage? (HD was at least mounting and files accessible)
    clicking the "X" to stop it just makes it "tink" with no change.
    Trying to quit TTP causes an endless "canceling running jobs" loop.
    Should i just force shutdown and call it a day?
    He will probably buy a new Macbook rather than replace the drive in this one, and it'd be nice if the apple store could migrate directly from this drive ... unless it's really easy to migrate across two generations, leopard to lion, from the Time Machine backup i got on an external drive after the internal drive was already having trouble...? (i've never restored or migrated from Time Machine).

    The Protection module of the Safety suite saves directory structure information from each of my four drives to each of the four drives. The Diagnostics module checks the volume structures of each of the drives, and the Smart module runs the SMART routines to check each of the two compatible drives for any impending troubles.
    When I asked whether I could be assured the new version wouldn't behave the same way, the reply I received was:
    "There are very few reports of problems with the features configured in the TechTool Protection system preferences pane as of version 5.0.7. The previously-reported problems were difficult to reproduce, and solving them required a substantial rewrite of the code in earlier versions in the TechTool Pro 5.0.x series."
    I'm not convinced that was a 'yes.'
    Your iCal idea sounds interesting, but keep in mind that the Safety suite of modules are within the Tech Tool Pro application itself and, when automatically launched, run in the background without the main application itself launching. Meaning, that iCal might launch Tech Tool Pro at the correct time, but will it launch the modules within?

  • 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.

  • 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 DVD won't boot with 10.5.6. How to fix volume structure?

    Is it just my newbieness, or is the Tech Tool Deluxe 3.1.2 DVD image not bootable with late 2008 MBP with OS X 10.5.6?
    I installed Tech Tool Deluxe 3.1.2 to Leopard 10.5.6. - ran it and it said I have problems with my volume structures. I followed the download button, gave my serial and downloaded the TTD.dmg image, burned it to DVD with Disk Utility (seems OK, as I can read the disk in OS).
    When I try to boot from the DVD, it just reboots in a while to my OS X (tried with c and opt buttons during start-up. I can choose to boot from DVD with opt, but again it just reboots in a while).
    Apple mentions that this version of TTD is not compatible with Late 2008 models - is booting one of the incompatibilities? If so, fine, but how can I fix my volume structure problems now, that tend to hang my Mac every once in while with big disk operations?
    Thanks for any possible help.

    I had the same problem myself. The TechTool bootable products on DVD won't startup an October 2008 release MacBook or MacBook Pro.
    From the Micromat website:
    Our current bootable products support all PowerPC and Intel Macintosh computers capable
    of running Mac OS X 10.5 or greater, except for:
    • MacBook (October 2008 Release)

  • Internal hard drive/repair: SMART status; Disk Utility, Tech Tool & More

    machine: 12" PowerBook 1.5 GHz PowerPC G4 (Aluminium) with 80GB internal HD
    internal hard drive (original): Hitachi Travelstar 5K100 series HTS541080G9AT00
    hard drive firmware: MB4AA5AJ
    ATA version: 6
    ATA standard: ATA/ATAPI-6 T13 1410D revision 3a
    I have monitored the SMART status etc. of my internal drive with smartmontools for some time. Occasionally, I would see an error or a failed self-test but later testing always succeeded and things did not seem to be problematic.
    At the beginning of this week, I started to see a lot of failed self-tests (though some still passed), a rising number of bad ("pending") sectors and reallocation attempts (though no reallocated sectors) and various other errors. The computer seemed to have trouble reading from the disk at times and Carbon Copy Cloner reported two I/O errors when cloning (a later clone succeeded). fsck showed errors although running fsck -fy repeatedly seemed to resolve them.
    The Apple hardware tests initially reported an error (2STF/8/3:ATA-100 ata-6-Master) but I hadn't realised I should disconnect peripherals before running it so I did that and repeated the test which found no issues. I ran the extended test a total of three times with no errors.
    As I continued to have problems, I booted from my clone and had Disk Utility wipe the drive by writing zeros to it. (I thought trying to get it to write everywhere would either finish the drive off or force it to reallocate the bad blocks. As I understand it, in normal use, the drive won't reallocate the blocks unless it can recover the data in the hopes of reading it at a later time.)
    I then continued monitoring the disk using smartmontools. At this point, short self-tests succeed but extended self-tests "disappear". They don't fail, they simply vanish. They begin and smartctl shows the test in progress but then no error or result is logged - it is as if the test was never run. The first time I did this, I got an error saying the SMART attributes could not be read but subsequent tests do not trigger even an error. Short self-tests continue to pass.
    There are now (according to SMART) zero bad ("pending") sectors but zero reallocated sectors, which seems odd. The raw read error rate fluctuates (zero one minute, many thousands a while later) although I am not sure it did not do this before.
    Disk Utility claims the disk does not support SMART status even though smartctl clearly shows it does. Disk Utility claims the volume is "OK".
    I ran Tech Tool Deluxe 3.04 from CD and 3.1.1 from my clone. In both cases, I ran all available tests on the drive. No problems were found.
    I am seeing some problems even while booted from my clone - yesterday, the system froze completely and I had to force a shut-down by switching off the power (fsck then found a minor error but repaired it). Just before this happened, I was unable to mount a disk image and was trying to rectify the situation when the system froze. It is possible that the errors fsck corrected were implicated in the freeze, rather than caused by it, since Disk Utility found and repaired similar errors for the other two clones I have (on different partitions of my external drive - yes, I know this is sub-optimal).

    Self-tests 1-8 were all run after I erased the disk. The others were run before I did so. Not listed are the extended self-tests I've started since erasing which, as I say, have simply disappeared.
    The checksum error regarding the log is normal for this disk. At least, I've got that error ever since I started using smartmontools for monitoring so I assume it is normal. (I installed this version of the software in about April 2008 and have used it since.) Also, starting offline testing has never succeeded on this disk (I think I checked into this at the time but can't quite remember - this is not new, anyway).
    Questions
    how should I interpret all this? (Why does Disk Utility say SMART is not supported while smartctl clearly shows it is at the same time? Why do the extended tests simply vanish? Is the drive definitely dying?) I do not want to replace the disk unless I absolutely have to because I understand that replacing disks in 12" PBs is no small matter and cost is an issue. I do not want to replace the machine unless I have to because cost is an issue and, also, I really like this computer and have no idea what I would want in its place, even if expense were no obstacle.
    if it isn't clear whether the drive is dying or not, is there some further strategy I can use to establish this?
    if the drive is dying, is a machine of this age worth repairing and, if it is, under what circumstances is it worth doing so? For example, it might be worth doing if you can do the job yourself, but that might be quite impractical for non-expert (not to mention, inexpert) users.
    if there is a hardware problem (which I obviously think is very, very probable at this point), is it definitely a dying hard drive? (I've seen people write ominous things about disk controllers etc. which I gather are more serious - or less repairable - than a "mere" dying disk.)
    what questions should I be asking you and what are the answers to those questions?!
    Many thanks for your patience in reading this far.

    The 12" PB internals are a bit more complex, for PB's. If you don't want to replace the hard drive yourself or pay someone to install it, you could always get an external firewire hard drive, and use it to boot from and for general usage. Would have to be firewire, since the PB won't book from a USB device. One example of what you could get is a 160GB external hard drive: http://eshop.macsales.com/item/Other%20World%20Computing/MS4U5160GB8/ . All the choices with that case are listed here: http://eshop.macsales.com/shop/firewire/on-the-go
    Have you called any Apple Authorized Service Providers to see what they would charge to install a drive for you? Whether you bought it or they supplied it? You can find a local one in the US at http://www.apple.com/buy/locator/service/

  • Internal hard drive won't mount after running Tech Tools Pro 5

    HELP.
    We have an imac 2ghz Intel Core 2 running OS 10.6.8.
    I ran Tech Tools Pro 5 to rebuild directory, optimize files, optimize volume. It ran over nightbut seemed to hang up optimizing the volume.
    Now the HD doesn't mount.
    I've tried a few fixes. Including running disk utility from a CD. The disk utility says the directory is okay but doesn't see the HD to verify or repair permissions.
    I've tried zapping the pram and safe boot, neither of which worked.
    I've been able to use the computer by booting from an external start up hd.
    Oddly, I ran a Time Machine back up prior to running TTP, but for some reason the only back up I see is from 3 months ago.
    Not sure why the recent back up didn't happen, but were missing some very important recent docs.
    I downloaded a trial version of Stellar Pheonix Mac Data Recovery and it seems to be able to see all of the data on the main HD.
    I'm wondering whether or not to spend $100 for full version to attempt to restore content of HD to an external.
    If I do this, I assume I'll have to erase the HD and reinstall data from the Stellar Pheonix collection, hoping that it's all intact.
    Does anyone have any other suggestions to get the HD mounted????

    Hi, never "Optimize" a drive before Repairing it AND having a backup clone to boot from.
    I assume I'll have to erase the HD and reinstall data from the Stellar Pheonix collection, hoping that it's all intact.
    No, I don't think you want an erase at all, you want a freah external drive to recover to first off.

  • G5 will not boot from system disk or from Tech Tool Pro 5

    Hi everyone - Having a bit of trouble and hoped I might find some answers here.
    I suspect my system drive was having some issues as it sounded like it was being taxed and strained as I would open up applications from it. Upon verifying the disk using Disk Utilities, the test would stop short with the following message:
    First Aid Failed
    Disk Utility stopped verifying "Macintosh HD" because the following error was encountered
    Filesystem verify or repair failed
    In addition, an error message came up (in red) on the disk utility screen as well saying:
    Volume header needs minor repair
    The volume Macintosh HD needs to be repaired
    Error: Filesystem verify or repair failed
    Normally from here, I'd start up the computer from the Tech Tool Pro 5 disk (holding down C key upon restart). But when I did this, the computer never responded. Instead, the power was on but the screens went black and the computer went into a very quiet "idle" mode.
    After about a minute, the fans began ramping up pretty high (and loud). This went on until I finally had to manually shut down the computer by holding the power switch down for a few seconds. I didn't know what else to do. Those fans were not coming down (not even after 10 minutes).
    Anyway, I pushed the power button again and held the C key down. Still, nothing.... The fans stayed idle, for a little while and then ramped up again just like last time. I hit that same dead end and powered down the computer via the power button.
    Is there an alternate way to boot the computer from Tech Tool Pro or the original start up disks? I'm having no luck, here.
    I'm on my way into town to purchase a new internal drive (something with about 1TB of space) so that my pro apps can swim a little instead of being being bogged down on a 250G drive.
    Thanks for any assistance, folks!
    Oh yeah.... Happy New Year to everyone!!

    The Install disk has version 10.4 on it. I have also tried booting from my OS 10.5 disk but with no avail.
    However, here is an update on my plight.
    Apple tech says that after hearing the symptoms, he thinks that one of the processors is shot. Being that my particular model of G5 (dual 2.7 processors) is a liquid cooled machine, it's possible that some sort of leak has formed and has either taken out a processor or has caused a processor to overheat. He says that this model of G5 has been known to do that. In this case, nothing will boot which makes me think that my original system drive may actually be okay. I'm taking it in for the tech to look at it and just be sure that's the problem. However, if it is a dead processor, the part alone would run $799 plus labor to install it. Frankly, that's just too much for me to pay to keep this old G5. I'd rather put that money towards a new or reconditioned Mac Pro 8 core or quad core machine.
    I've owned several Mac computers in the past and perhaps this is the frustration talking but it seems that no matter how diligent you are in maintaining your Macintosh, these machines only seem to last about 5 years before something majorly wrong happens (mother board, processor, etc). Can I expect this same, limited time frame from a new Mac Pro? I mean, am I just being paranoid?

  • Tech Tool Deluxe 'Surface Scan Failed-'

    Surface scan repeatedly failing, no recent change to iBook settings, I suspect that this problem may have been caused by m-audio software, however I believe it has been properly uninstalled. Advice?
    Error message reads;
    'Surface Scan Failed - 212 errors
    The Surface Scan test will scan the disk for bad blocks.
    Media defects cause this test to fail. You should consider backing up the device, reformatting the media, replacing the data, and then testing again.'
    I am unsure as what this report is prompting me to do. What does the term 'media' mean in this context? Which data should I be trying to replace?
    Please forward any tips on how to resolve this issue.

    When I use the disk utility application the volume passes verification, is this contrary to Tech Tools or are they analyzing different elements of the drive?
    Yes, different, DU is just basically checking part of the drive, where Directory info is stored & such.
    Laptop drives are generally a lot shorter lived than regular drives, which now seem to last 3 to 5 tears.
    Although these errors are present it doesn't seem to be effecting my day to day running of things at the moment...
    There's a Train Wreck coming up ahead though, you can avoid it, or wait 'till it hits!
    Not certain which iBook G4 you have, but here's some ideas on HD replacements...

  • Help! Tech Tool Scan shows failures

    Tech Tool Deluxe show that Format Check failed, Directory Scan failed, Surface Scan was skipped and Volume Structure failed. Can someone help me understand what is going on and what I should do to fix these problems. I called Apple Support yesterday. The advisor told me to insert the install disk, go into Disk Utility and click repair and yet today when I put in the Tech Tool just to check if things were working properly, it showed the same issues are still happening.

    I don't have a copy of TTD, so I'm not familiar with it, but were you just scanning from problems, or did you try to have TTD repair the issues? Did you have Disk Utility repair the disk as instructed? If repairs are failing with both TTD and DU, then your drive may be in the process of failing, or it may be so badly corrupted that it can't be repaired. In the former case, you will simply have to replace the drive. In the latter, repartitioning it with Disk Utility and then reinstalling the system and all your data may bring it back to life.
    Note that your first order of business regardless should be ensuring that you have a good set of backups (a minimum of two backups). See my [Mac Backup Guide|http://www.reedcorner.net/guides/backups>.

  • Tech Tools for Intel?

    I spent time with a Genius at the apple store yesterday. He had no success, but advised me to download tech tools and use it to try to retrieve files before reinstalling system software.
    Is there a version for the Macbook (Intel)? I have not been able to locate it.
    Here's the history of what's been done since I got the dreaded grey folder/question mark:(
    I used the Disk Utility/Repair Disk and got the following report:
    First Aid Failed
    Disk Utility stopped repairing "disk0s2" because the following error was encountered: The underlying task reported failure on exit
    Verify and Repair disk "disk0s2"
    Checking HFS Plus volume.
    (red font) Invalid B-tree node size
    Volume check failed.
    ERROR: The underlying task reported failure on exit.
    1 HFS volume checked
    (red font) 1 volume could not be repaired because of an error.
    I also performed the Hardware test on the startup disk and the report said there are no problems.

    Better check it with apple care, they maybe will offer a discount or give you the newer version for free.
    Or pre-owner tech tool pro might have upgrade discount from micromat (the vendor).
    Micromat is also working on an upgrade for TechTool Protege to support the new Intel-based Macs. Like the TechTool Pro 4.5 update, Protege owners will be offered a low cost update as well. Micromat expects to have this update available to Protege owners in approximately 30 days after the release of TechTool Pro 4.5. This update will include a convenient "flash" application that allows the user to quickly and easily configure Protege to the system(s) on which they intend to utilize the device. As with the TechTool Pro update, Micromat expects this update to ship on DVD media for $25.

  • Kernel panic and Tech tool

    I really did it this time. Problem described below ...
    I dowloaded some files off a flash drive. When finished, Idragged the drive icon to the trash and pulled the usb connection. After I restarted later I noticed the usb mouse wasn't working. Thought, rats, I pulled the plug on the drive too early. Then I compounded the problem by using techtool 4.0 to troubleshoot. (yeah, I know but I didn't check the support articles beforehand). Tech Tool identified a volume structure problem and I let it try and rebuild volume structure. Now I have a bad kernel panic on startup and the following really annoying problems
    Won't start up from the any cd.
    Starts up in target disk mode but my G5 won't recognize it - no icon appears
    startup in firmware required to eject cd - now that doesn't work either
    pram reset didn't resolve anything
    Wont start up in safe mode - same kernel panic
    "X" key to force startup in OSX displays drive icon but results in same kernel panic
    G4 titanium   Mac OS X (10.4.7)  

    Reformattting the drive and reinstalling everything on it is an option, given that unlike the common herd, you've had the good sense to back everything up. When doing that, it would be a good idea to use the option of zeroing the drive completely, even though it may take a long time. Doing so is likely to reveal any hardware defects in your hard drive; a simple erase would not. Replacing the drive would clearly be premature at this point: it may simply have a scrambled directory and no hardware problems at all.
    If you have a DiskWarrior CD, it would be worth trying to boot to that and use it to build a new HD directory. If successful, that would save you a lot of reformatting and reinstallation time.

  • Emac won't start up and tech tool doesn't recognize my hard drive.

    My emac's been running slow and crashing. Today it got to the point where I couldn't even use the finder when I started up. I tried to start up from tech tool and did so successfully. It recognized my hard drive and I ran the tests and repairs, but during one of the tests it got hung up. I restarted the computer and now all I get when I start up is a little folder in the middle of the screen with a question mark. I started back up from the tech tool cd, but it doesn't recognize my hard drive anymore. I'm really scared I've lost everything. I could sure use some help! The emac is running Tiger.
    Jane

    jamech,
    Welcome to the Apple Discussions!
    What version of Tech Tool where you using? If it was an older version, incompatible with OS X 10.4 Tiger, that could actualy make things worse --- see Only use Mac OS X 10.4-compatible disk utilities with Mac OS X 10.4 volumes.
    The version of Disk Utility that ships with OS X 10.4.2 and higher is more capable than earlier versions. Try booting from the Tiger install disc, then open Disk Utility from the Installer menu and see if you can run Repair Disk on the hard drive. Refer to Using Disk Utility and fsck. Take note of any errors reported and post back with the results. If errors are reported repaired, re-run Repair Disk until you either get a clean bill of health or a report of unrepairable errors.
    When you get the Mac running from the hard drive again, you'll need to determine why it was running slowly in the first place. Anything reported by Repair Disk is of interest here. You could try using a third-party utility such as OnyX to clear caches and logs, and to make sure the maintenance scripts are current (there's a timer in Tiger than will force the scripts to run if you normally have the Mac shut down or in system sleep overnight; the timer is based on elasped time and isn't exact).
