Hard Disk & Disk Utility

I was installing Boot Camp. Once I have set the partition sizes and clicked partition, I got the message "Your startup disk cannot be partitioned because verification failed." So I started from the Install Disk 1 and used the Disk Util to verify the disk and this is what I got
Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid extent entry
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
And when I tried to repair the disk, I got the message "Disk Utility stopped repairing Macintosh HD because the following error was encountered: The underlying task reported failure on exit."
In addition, when I start my MB, an folder icon with question mark at center shows up briefly before the Apple logo.
Any suggestion. Hope do not have to erase the HD.

Boot from the OS CD and run the disk utility from there.
It is likely that a file/area of disk needs repairing but is in use.

Time Machine appears to be doing back-ups, but they do not appear on the external hard drive. The last one I can find is June 30. I did a utility scan of the hard drive disk and it is fine.

Click the Time Machine icon in the menu bar. The time of the last backup is shown in the drop down.

When I restore my Mac with Time Machine and then want to partition my disk, Disk Utility always says incorrect number of extended attributes

When I need to restore my Mac from a time machine backup and then partition my hard disk (the disk inside the computer not the time machine disk), Disk Utility always says "Incorrect Number of Extended Attributes". I then boot into Recovery HD and run disk repair. The result? "The volume Macintosh HD appears to be OK". So then I reboot into normal OS and try the partition again, still Incorrect number of extended attributes. I have even tried /sbin/fsck -fy in single-user mode but it still says the volume is ok. I have tried partition my disk in the recovery HD and it still fails.
Can anyone please help me solve this problem?

Try something stronger, such as DiskWarrior or TechTool Pro.

Drives stopped mounting with FW800, but FW400 is OK. Worked OK before, but won't now. Tried new cables, zapping pram, Disk Repair Utility. Any suggestions? Thanks.

If your external drive does not have an independent power supply, you may wish to consider a couple of lower-cost options before tossing the drive. Bus-powered drives have no external power source and must get all their power from the computer. They can exceed the computer's USB energy budget.
Cheapest option:
1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
This gets power from two of the computers USB porst sna can provide enough power to wake up an under-performaing bus-powered drive.
If you don't have enough ports to use this, try the next cheapest option:
Newer Technology 7 Port Hi-Speed USB 2.0 Hub with Power Adapter for Mac & PC
Such a hub has a an independent power supply to make up for wahat the comptuer fails to provide.

Disk Repair Utility Full Disk Error

Today, my MBP froze, as in it no longer responded to keypresses or moving the mouse, so I held the power button until it powered off. Whenever I try to power it back on, it comes up with the apple logo on a gray screen, and a progress bar briefly appears beneath the apple logo, flashes a few times and dissappears, then the computer turns off.
By running the disk repair utility from the OSX install disk, the OSX partition of my hard drive needs to be repaired. When I try to repair it, it gives me an error saying that the disk is too full to do a repair on (I probably have ~10GB free, so this makes sense), and I need to wipe my disk and reinstall OSX .
I have windows installed via bootcamp and I can still boot into that and see my contents of the OSX partition (e.g. I can play my music, watch movies, open documents all of which are on the OSX partition, I just can't boot to it.).
Although probably unrelated, I've run the diagnostics, and everything came up okay. I've also tried holding shift during boot (trying to get OSX into safe mode) and holding command-option-P-R (clear the PRAM) during boot, neither of which helped.
My current strategy is copy a lot of data off my OSX partition from within my windows partition to an external HDD, in order to free up space on my OSX drive, so that hopefully disk repair can do its job. Does anyone know if this will work, or if not, can anyone recommend an alternate work around?

Backup your files, if possible. Your only recourse is to reformat the drive and reinstall OS X. Do not copy or backup files from Windows. If at all possible boot from another drive like your external HDD by installing OS X on the external drive (unless it is already a bootable drive.) You can then copy your data from the faulty OS X volume before erasing it.
You should never permit your free space to drop so low. One should maintain 10-12 GBs or 10-15% of the volume's total capacity, whichever is greater.
Since this problem will likely recur I suggest you consider just replacing the drive with one that is considerably larger. I would also be sure to arrange to maintain a bootable backup on an external drive in case problems such as this one occur.

Is DSC Citadel compatible with the Windows 7 disk defragmentation utility?

Is DSC Citadel compatible with the Windows 7 disk defragmentation utility? I'm seeing gaps in trace data, and noticed Win7's defrag utility was scheduled to run weekly (default setting for Win7). I didn't see such gaps when running DSC 8.6 on XP.
- Andrew

Hello andrew johnson,
Based on your description the Windows 7 disk defragmentation utility may be limiting write operations to the Citadel database. Does your current setup defragment part of your hard drive on a weekly basis? In order to get more information regarding this issue, you could turn of this utility in order to isolate where the gaps in trace data are occurring.

10.8.4 Logic Pro Hard Drive (Disk I/O) issue

Hey,
since yesterday my Logic Pro (9.1.8) has a big problem. After I installed the Update 10.8.4 the Hard Drive (Disk I/O) Display overloads everytime, when i start to play my vocals/tracks. Even older projects (i never had problems) with just 20 tracks and without third party plugins the HD Display goes up and with the latest project (49 Tracks) i cannot even create a new track anymore. It says "not enough memory" and then it crashes.
I bought my Imac some months ago. Just some informations about my Imac.
- Late 2012, 21,5"
- 16 GB Ram
- 2.7 GHz Intel Core I5
- Hard Disk 5400 revolutions per minute, Sata (still 900 GB free)
Basically I bought my Imac to create music and to use logic pro - its very frustrating .. i cannot work anymore.
I tried everything - change the settings, change the buffer size, not to use my interface, 32bit to 64bit, to delete Autotune (my only third party plugin) from the AU-Manager. I even had a call with the Apple Support (2 hours long) and they couldnt find a solution ..
If they cannot find a solution, i think its even harder to find someone here, who can help me. So my question is just, is there someone else who has a similiar problem with the update?? .. I'd say a problem shared is a problem halved :-)
thank you & nice greetings from Austria :-)

Hello Stefan,
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...

Open Console in Utilities & see if there are any clues or repeating messages when this happens.

Disk Defrag Utility

HI, I have a G5 and have just
installed Final Cut Studio
I am wondering what the best
Disk Defragmentation Utility is
I already have Disk Warrior, but is
there something better
I notice that my fans start up randomly and stop
and I may need to erase my Hard Drives eventually
and start fresh
thank you

I notice that my fans start up randomly and stop
and I may need to erase my Hard Drives eventually
and start fresh <
No, they don't. The fans come on for specific reason and the only way to know is to have Activity Monitor or another Terminal window/app open.
The idea that defragmentation can solve anything is a holdover from the ancient days of 60meg hard drives. Disk Warrior is a directory rebuilder only, that's al it does, it does not defrag anything. The risk of something truly horrible happening while you are defragging is greater than the perceived benefits but you do this at your own risk. Be sure you have a battery UPS on your machine. The best way to defrag a system drive is to use a cloning tool, make a clone, erase the drive, and clone the clone back to the source of the clone.
Get on the Net and research defragmentation. Make your decision carefully. And then post your experiences for the rest of us.

Disk repair utility & printer issue

I will admit right now that until last night, have never touched an iMac but I have a friend that due to health issues, needs a hand. Can I ask a couple of questions of this forum?
1: She has an external Lacie H/D that is making wierd noises after being knocked over. Her backup software says to run the Disk Repair Utility. I haven't the slightest idea where to find this Disk Repair Utility, nor if I can run it on an external drive.
2: Her printer, mac book and iMac were recently moved from one location to another home. I need her printer connected wirelessly to both computers. I was able to get her Macbook connected but I am having issues with iMac. Can I uninstall her printer and reinstall? Not even sure how to do that basic process so advice would be appreciated.

Disk Utility should be able to check the LaCie - whether it will be able to complete any repairs that may be needed will become obvious when it's attempted. Disk Utility is normally in the Utilities folder within the Applications folder.
Regarding the printer, yes you can uninstall it in System Preferences>Printers & Scanners (or similar wording depending on version of OS X). The +/- buttons add/remove printers.
If you still have problems, post back.

Is it possible to put a 1TB hard drive disk in my mid 2009 13 inch macbook pro?

I want to upgrade my hard drive disk (macbook pro 13 inch mid 2009) from 160 GB to possibly a 1TB. If I bought a 1TB hard drive disk would it work in my computer and would apple install it for me? If not is there anywhere in manhattan thats an afiliate of apple that would do it? I checked out Ifixit.com and was looking at how to do it on my own but honestly I'd probably screw it up. Any help would be much appreciated.
Thanks

they would not install a hard drive you purchased somewhere else, however I'm sure a computer repair shop in manhattan that would be willing to. If you are looking for an Apple affiliate, or an AASP, here: https://locate.apple.com/service/?pt=4&lat=40.7902778&lon=-73.95972219999999. Call them and ask if they would do it for you.

Purchased Lion, installed it - once I log in - i get the curtain and message to hold the power button till it shuts down. Worked with the disk repair utility - fixed permissions - still can't get past the "black curtain of death" any suggestions?

My machine was patched to date 10.x.x. I was lucky to get an internet connection and I selected the option to re-download Lion... its curruently being downloaded. What if that doesn't work?
Any thougths would be appreciated.

There is a question mark on my hard drive disk, how do I get rid of it.

There is a question mark on my hard drive disk, how do I get rid of it. I recently went to the genius bar in Albuquerque, NM and they restarted it and did a partition on it and what I needed was fixed but I still have a question mark on my start up disk.

There is no startup system on it. Or, you need to open Startup Disk preferences and select a startup disk. Or your startup disk lacks a name such as "Macintosh HD," for example.

Running the Disk Cleanup Utility in Windows 8

Sometimes, inbetween uninstalling and reinstalling software/drivers, it is a good idea to run Windows Disk Cleanup Utility. The Disk Cleanup utility helps free up disk space by deleting unnecessary files from your computer.

Create PXI Format Hard Drive Disk

Hello,
Can i use a "Create PXI Format Hard Drive Disk" created from LV 8.5.1 ver for formating the PXI RT controller which is having LV RT 7.1.
Regards
Aks
(Appreciate answers by giving KUDOS)
Hit the stars.............. sky is not the limit.

Hi,
I think you can, but you'll need LV (RT) 7.1 on the host PC to install LV RT 7.1 on the PXI controller using MAX after formatting it.
(Unless you have an image created by the RT replication toolkit, but then other problems might arise...)

Disk Copy Utility missing

I understand that there is a Disk Copy Utility in the Utilities Applications in Mac OS X Jaguar V10.2. But I have the Mac OS X 10.4.8 (Tigier) and I cant find this utility. How can I access it ?

Disk copying is handled through Disk Utility. There is no separate utility in Tiger.
