OS X :: How To Repair Startup Volume?

Feb 12, 2010

I have Onyx and I did the usual diagnostic. It then says that "startup volume needs to be repaired" and that I need to boot into my Mac Os X install DVD and go to Disk Utility. I put in the DVD, press restart, and hold C. While my mac is rebooting it ejects the disk and takes me back to my normal desktop. What did I do wrong? Or what can I do to fix it?

MacBook Pro :: Startup Volume Keeps Need Repair?

Jan 14, 2010

I'm using Onyx every so often when things start to get sluggish. Recently, things keep flying out of whack for no obvious reason. Like, USB ports stop working, or icons won't load. When I run Onyx, it tells me that the startup volume needs repair. I'll put in the Snow Leopard disk, repair the startup volume and return to Onyx, which then says everything is fine and goes about its business. Then, after not too long, things fly out of whack again and I'll need to repair the startup volume again.

What causes the startup volume to need repair? Is there some way I can avoid this kind of thing? Is there something I'm doing that's making this happen?

This would be an obnoxious problem to try and recreate for the Apple store people. Taking it in there, they'll probably just repair the startup volume and send me on my way.

OS X V10.4 :: Ipod (and IPhoto) Not Working After Tiger Startup Volume Repair

May 19, 2012

Ive recently had to repair my startup disc volume/reinstall Tiger and now my iPod doesnt store songs after I sync it. All of my music is in iTunes and everything else seems to be working however once I disconnect my iPod NOTHING is there.

Ive been looking through all the previous discussions but cant seem to fix this on my own. And Im not even sure if I should be posting this question on here or in another forum...because Ive also noticed that there are no pictures in iPhoto .when I did the repair...it asked me if I wanted to save a copy of the previous system which I did.

Info:
PowerBook, Mac OS X (10.4.11)

OS X :: New HD Not Showing Up In Disk Utility - This Volume Is The Startup Volume And Cannot Be Erased

Aug 10, 2009

I have my imac apart right now and replaced the internal HD as it was not working. I assume the problem is the new one is not formatted with OSX, so from the INSTALL CD I opened the disk utility and see only one drive called "MEDIA".? Or is that just part of the install dvd that looks like a HD? In the system it shows as not formatted, 0 bytes. When selected in Partition it says :

"This voume is the startup volume and cannot be erased. Size 7.1 GB The disk is not writable and cannot be partitioned"

So i guess thats not my new HD I am seeing? Other than that there is only the two OSX install CD icons.

What does that mean? In disk utility it says I need to repair it. However after I click "Verify Disk" and it spits out their information, it doesnt let me repair the disk still. So, how do i repair the Volume? What is the volume? This isnt a hardware failure is it?

OS X :: Volume Repair Options At Start Up With A System

Dec 11, 2010

I have a MacBook that is running leopard. After running a volume repair that failed I tried to restart my laptop, but when it gets to the blue loading screen, it takes forever and then shuts off. I can still run the Mac os x installer. When I go to disk utility, the Macintosh hd tab is visible, whereas it wasn't available before. Okay scratch that it isn't available anymore. Though, I just clicked on startup disk and it is visible there.

Desktops :: Disk Repair - Volume Structure Failed

Feb 11, 2010

I have recently purchased an iMac (21.5" - 3.06 GHz Intel Core 2 Duo - 4 GB 1067 MHz RAM - 1 TB harddrive) with OS X 10.6.2 installed. I have to say that after over 20 years with MicroSoft I am enjoying the stability and quality of the MAC. Anyway, as part of my education in the care and feeding of a MAC I ran the TechTool app yesterday. I had no indication that anything was wrong with the computer - but, I would like to become familiar with the various utilities for the care of the machine "before" a problem occurs. As the app ran I was pleased to see that all the tests passed (Processor, RAM, Video RAM, etc.). However the computer failed the last test: Volume Structure.

Here are the directions I was given at the end of the test: Volume Structure Failed
TechTool Deluxe can scan volumes for problems related to the numerous structures that are necessary for the volumes to operate correctly. If problems are found, TechTool Deluxe can attempt to repair the damage to help reduce the chance of future problems. If TechTool Deluxe has discovered problems with the structure of a volume, allow the program to repair the problem. Quite often these issues are minor, but sometimes they can be indicative of a more serious problem. If the problem persists, consider backing up the device, reformatting the media, replacing the data, and then testing again.

I was also instructed to access the Apple site and download the most recent version of TechTool Deluxe that can perform repairs. I downloaded the software and followed the instructions to open the file in the Disk Utility app and burn a CD. Following the directions I then booted up on the CD by restarting the computer while holding the "C" key. The computer booted up on the CD and loaded TechTool Deluxe. I ran the same tests as above and once again the Volume Structure failed. When I clicked on repair it seemed as though the program was trying to fix the problem - then it abruptly stopped and stated that the Volume Structure could not be repaired.

I removed the TechTool CD, rebooted the computer, installed the TechTool Deluxe that I downloaded from Apple, and ran the Disk Utility. When I tried to "Verify" the disk this is what appeared: Disk Utility stopped verifying "Macintosh HD". 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. Following these instructions I rebooted the computer using the Mac OS X installation disk - and the only option I found was for an installation of the OS.

Hardware :: External HDD Refusing To Mount - Volume Needs Repair

Jan 22, 2008

Last night I encountered a problem with my seagate FreeAgent external HD/D. I right-clicked on the desktop icon to eject it as per usual and once the icon had vanished I pulled out the USB cable. However, I then got a message saying that I didn't eject the device properly and might have lost data, etc. When I plugged the external drive in this morning I found that it wouldn't mount. I am in a state of panic at the moment because it is almost 150gb of data that I really did not want to lose! I read in one of the previous threads that this is a common problem amongst macs but I wasn't able to discern if this was a permanent error and if it means my drive is shafted. I ran disk utility and this is what it came up with:

Verifying volume "disk1s1"
Checking HFS Plus volume.
Invalid node structure
Invalid B-tree node size
Invalid node structure
Invalid B-tree node size
The volume needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair

I tried to repair it using disk utility but it wasn't able to do it. I am now using the demo of Data Rescue II to do a thorough scan which will take several hours but I'm wondering what options I have. Are there any other mac tools I can use? I am a total newbie when it comes to macs having only made the transition from PC to Mac several months ago and I don't know what tools I can utilize to fix this problem, if it even can be fixed.

OS X V10.7 Lion :: Disk Utility Can't Repair Time Machine Volume?

Jul 2, 2012

I have an external WD drive in a self-enclosed case, both purchased from OWC, used for my Time Machine backups. The disk and backups have been running just fine since I began using this disk over a year ago. 

When I plugged in my disk yesterday (USB), it didn't mount. I ran Disk Utility on my 'Time Machine' partition, starting with verify disk. It reported that it needed to be repaired. When I run repair, it runs for several minutes and I see information of what is being done -- incorrect block count for file shutdown_time, incorrect block count for file permStore, etc -- but I always ends with "Disk Utility can't repair this disk" and that it needs to be reformatted. 

I've run Repair Disk multiple times, all with the same answer so it seems running it again won't change the problem. Reformatting and starting fresh with Time Machine seems to be the only course of action 

What specific issues should I be aware of as I reformat my Time Machine drive/app partition?

Info:
iPhone 4S, Mac OS X (10.7.4), MBP, 2.4 GHz Intel Core i7

PowerPC :: Hard Drive Not Working / Repair Volume Failed Could Not Unmount Disk

Jul 17, 2009

So so annoyed right now. Today my 12" G4 powerbook started to become slow, lots of spinning wheel, delayed menus etc. I checked file permissions, rebooted and it just kept on getting slower. Eventually it wouldn't get past the white apple screen.

I booted off the Tiger DVD and ran disk utility to fix and repair permissions again. It wouldn't let me repair the disk as I kept getting this error:

'Repair volume failed with error could not unmount disk'

I had to reboot again, and eventually my hard disk no longer appears in Disk Utility. I tried to boot into safe mode and get this:

'"I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus"

So now I pretty much can't do anything with it. Failed Hard Drive?

OS X :: Volume Resetting To Max On Startup?

Aug 1, 2010

Sadly I have a feeling I will be here asking for help for most of the week (if not month) as I run into problems.

Everytime I reboot my system, my volume is set to the max. I can lower it without issue, and if I log out and back in, the volume stays the same. It only happens when I reboot. Anyone know why this is happening and/or how I would go around fixing the issue?

Edit: I think the issues I am running into are caused by bad permissions on most of the com.apple.* files. Will the file be recreated with the correct permissions if I move/delete the files? If not, what should the permissions be so I can manually change them back.

Before I forget, yes I have been repairing permissions, but not all the files are being fixed.

Software :: Startup Volume Is Missing?

Sep 29, 2008

The problem began with the Mac running slow and then freezing. Shutting down and restarting (if possible) gave some improvements until finally I got to a point where I could not open up anything from the desktop. I was able to open up my applications from a Firefox image on the desktop. If I placed anything in the applications folder I could open it up as normal. After doing some back up I then began to try different lines of appraoch for solutions:

First: I went into the Disk Utility and verified the disk and repaired permissions. This did not solve the problems.

Second: I booted the computer with TechTool Deluxe. I ran the tests and it found an error on the Volume it scanned---Error -4. I then did a repair of this error which went through successfully. The program then proceeded with another scan and uncovered Error -694. I let it run through the fix process but chose not to save the changes because it eliminated so much of my data. I was hoping I could find another solution before having to resort what appeared to me to be so drastic.

Third: I thought I might try and re-install Mac OS X 3.9 but there was no volume showing to write it to.

Fourth attempt: I tried to boot the computer with my Mac OS X installer CD and then to use disk utility from there. I noticed that my startup volume appeared in the list of options within disk utility but was 'greyed ' out instead of bold faced. I was able to select it and run the Repair function but that failed. I also noticed that when I selected that start up disk it said it was unmounted. I clicked on the mount button but that did not do anything. I then quit installer and it asked me to choose a startup disk, I chose Network Setup since it was the only option. After that when I would try and start the computer I would get a flashing world sign followed by the folder with a flashing question mark. I realize now it was trying to start from that Network Setup, but could not and afterward it could not find anything to boot from and thus the question mark

Fifth attempt: I tried to boot into Safe Mode. I could not. I tried to boot while holding down the Option key. Startup Disk Manager comes on the screen but there are no start up disks to choose from. It appears my Hard Disk has vanished.

Sixth attempt: I then booted again from TechTool Deluxe and ran through the whole process again, but for some reason the repairs could not be completed. I tried several times but the program keeps giving me the same message: "The Volume Structure Rebuild could not be completed"

The best I can figure is that I had a progressively failing hard drive which finally totally gave out. This seems to be the best explanation for all of the problems but I am hoping that someone on here might have a solution for me which I have not discovered yet.

OS X :: Time Machine Reports Incorrect Volume / Unable To Repair Incorrect Allocation Blocks

Nov 8, 2009

I am pulling my hair since friday trying to get my MBP's time machine work with a 1TB drive connected to a early 2009 AEBS. First I spent half a day doing the first backup by connecting the hard drive directly to Mac using USB and later when I connected that drive to AEBS, time machine would not recognize the drive as the same one and I had to spend a good part of yesterday backing up my complete drive again.... and just when I thought I can rest easy knowing that my eternal dream of getting time machine work wirelessly, I saw time machine complain that there is not enough free space left to backup my paltry 103 GB worth of data on just second day.

Turns out, the Time machine backup volume (volume created by time machine on the AEBS disk) shows that the used space is 1TB.... but the size of the sparsebundle is only 103GB and my airport drive mount itself shows plenty of free space (800GB).... I have tried to search for similar problem, but I couldn't find much help... can anyone help me out here....

Btw, when I tried to repair the volume in disk utility, it says something about incorrect allocation blocks and then says it cannot repair and I need to backup and reformat the drive or something of that sort....

MacBook Pro :: Repair Corrupted Hard Disk When Don't Have A Startup Disc Provided By Apple?

Feb 24, 2012

So my MBP was really making horrible clicking noise and I figured out that my start up Lion OSX disk partition is corrupted. I have three partitions. One for Lion OS X, another for Documents and another for Movies and Downloads. When I run disk utility and verify other two partitions(documents and movies/downloads), they appear to be okay but when I do the same with Lion OS X then it says: 

The volume Lion OS X was found corrupt and needs to be repaired.Error: This disk needs to be repaired....then use Disk Utility to repair this disk. Is my hard drive gonna die soon? Or will it be okay if I just format my 500gb hard drive completely and install the fresh copy of Lion OS X again? I don't have a recovery disc or what so ever provided by Apple anymore. I have a DMG installation file of Lion OS X and a USB flash drive(4 GB approx). How can I repair the disk partition without the recovery start up disc?

MacBook Pro, Mac OS X (10.7.2), 2009 17 inches

Windows On Mac :: Bootcamp - How To Delete A Previous Volume On Startup Disk

I'm retrying to install windows on my mac. It's the second time I'm trying, but it has somehow become way harder. The first time I installed Windows, everything worked perfectly, untill I noticed that SP2 wasn't installed, and I couldn't install it on my windows, somehow.

Now I'm trying it with a different version of XP (Pro), but Bootcamp is giving issues. I haven't deleted the old volume/partition (don't know the difference) of windows yet, as it is installed on my startup disk and Disk Utility won't delete it .
