Superdrive replacement not working? Try "repair disk permissions"

Like many other folks, the superdrive in my iMac 7,1 died. I ordered a replacement from Powerbookmedic and installed it following ifixit's guides. Upon booting the iMac I found that the SuperDrive would accept a disc and the iMac saw the SuperDrive but OS X wouldn't recognize any disc I put in the drive and after trying to read it would eject it. After trying various things, I found that other users on my iMac were able to use the new drive just fine, it just wasn't working for me.
I tried various fixes but in the end "repair disk permissions" under disk utility did the trick. Posting here in the hopes of helping others. Joel

I cant access any of the files on the hard drive to back up. Do you know of a link on how to format and reinstall. It would be my first time. I have diskwarrior and it will not load at all.
Under the Erease tab I have
MAC OS Extended
MAC OS Extended (Journaled)
MAC OS Extended Case Sensitive
MAC OS Extended Case Sensitive journaled
MS-DOS Fat

  • Working while repairing disk permissions?

    Is it ok to do remedial tasks while repairing disk permissions, such as surfing the net, checking email,etc? As long as I'm not installing anything or making system changes?
    Thanks,
    Wesley

    yes, it's quite ok to work while repair permissions runs.

  • I Mac Not working, and Repair Disk not working

    I have been trying to help out a friend with his I Mac loaded with OS X. It will not load up just by pressing the power button. I have tried running the Disk Utility and get the following messages. I am probably at the understanding of this hard drive is just toast. My next step will probably be to Erease the hard drive completely and try to install the OS X. But i am a little leary about doing that. If anyone could suggest something before I do this, that would be great. All so I have tried booting from the install disk and reinstalling the OS X with out the Formatting of the disk and it does not Allow me to access the Mac HD. There is a big yellow "!"

  • Repairing Disk Permissions - Not Working with Lion

    I simply am not able to repair disk permissions when my Mac is booted normally - the disk utility hangs and never stops - when I boot in recovery more I can run the utility just fine - and then boot as normal.  I am wondering what might be causing this or if anyone else is having a similar problem?

    With Lion, it is best to do any disk repairs via the recovery partition
    And why do you say that?  I have heard no such thing, and this was never the case with previous systems.  It has always been recommended to repair permissions while booted from the system whose permissions need to be repaired.  Do you have documentation that this recommendation has changed?
    Joe, repairing permissions works fine for me without needing to boot into recovery mode.  Are you giving it plenty of time to finish?  Sometimes it may seem to be frozen... sticking on "less than a minute" for well more than a minute, for example.  Have you repaired the hard drive (which you do need to boot from the recovery partition to do)?

  • OS won't start up. Repair Disk Permissions moving at snail's pace

    After installing a large program (World of Warcraft), my MBP seemed to slow down with frequent beach balls popping up. I decided to restart the system, but now it can't get passed the grey Apple screen. A spinning gear appears on that screen, but nothing else.
    The Mac boots fine using a separate firewire drive, so I thought I'd try repairing disk permissions on the MBP drive. Unfortunately, the progress bar in the disk utility fills to about a tenth of the way, and then stops. No error message or anything, just no progression.
    Any thoughts?

    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the Erase tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume, then chose MacOS Extended Journalled.
    6. Click Erase & look for Options. choose Zero 1 pass. This is the option that may mark out the bad blocks.
    It still may mean your HDD is going out & may not last though.

  • Repair disk permissions does not work

    Repair disk permissions does not work. Disk Uitliy fines many incorrect permissions (ACL found, but not expected) and says that it would repair it. However, when checked again, it finds the same permission errors.
    I have tried Disk Utility as well as the command line "sudo diskutil repairPermissions /" (which probably does exactly the same as Disk Utility).
    Any hints?
    C.

    Are you trying to Repair Permissions because you have file access problems in the System files, or just because you think you need to do it?
    If the former, please explain what you are seeing. If the latter, stop wasting your time.
    The things it doesn't repair are not repaired because there is nothing broken. The orginal Receipts files have the old settings, and subsequent updates have changed the permissions on those things to what they should be, now. It will report the differences it finds every time you run Repair Permissions because they will always be different and they should be the way they are.

  • Repair Disk Permissions not working?

    Based on a printer problem, HP suggested that I run Repair Disk Permissions. I did, generating 9 pages of fixes.  But if I clear the history and run it again immediately, the same list of repairs is generated, suggesting that nothing was fixed.

    It's no problem, see this

  • External Hard Drive no longer working. Repair disk not working

    It appears in the finder, but says I should take everything off of it and restore it.
    Weird thing is, it says it's a 465GB capacity, and 236 is available, with 56,708 files on there, but it says 0 items in the finder, so it can't see everything.
    I have important stuff backed up on there, but it's not loading.
    Disk utility won't repair the disk, and the repair disk permissions are greyed out.
    Incorrect number of Access Control Lists
    The volume KYLE-HD could not be repaired.
    Error: Filesystem verify or repair failed.
    Those are what I get when I try to repair disk
    Also for owners enabled, it says no, not sure if that is impt. or not.

    I'm experiencing a similar issue...
    In the middle of copying items from an external drive (ironically, to reformat and enable Time Machine), finder popped up a 'Device Removal' warning... and the two volumes (partitions) of my external HDD disappeared and would not remount. (Disk Utility would not show the drive or volumes.)
    I disconnected, powered down the drive and tried reconnecting - same problem... volumes wouldn't mount and Disk Utility showed no disk (despite the hdd showing up under system profiler just fine).
    Tried again, and got the problems Kylecool is describing.
    Luckily, most of what I wanted to get off the drive had already copied... there's just one more essential (iPhoto library... yes, I have a backup - but I spent a few hours a couple of days ago integrating two libraries into one [a painful process that I don't want to repeat]...).
    I'm in the process of copying the library now, and will then reformat - so hopefully no great loss... but thought I'd add my experience to that of Kylecool's as it may be an issue with 10.5?
    (HDD is connected via FW400.)

  • Trying to install Lion. says this disk is not enabled (journaled) - but when I look at the drive it actually is os extended journaled - Stuck! Have tried repair disk permissions and still no luck

    trying to install Lion. says this disk is not enabled (journaled) - but when I look at the drive it actually is os extended journaled - Stuck! Have tried repair disk permissions and still no luck - any thoughts? Have spent two weeks trying to get apple support and itunes to help me get lion after a hard drive fail and now they are closed and I really just want to get moving!

    Are you installing OS X Lion over an existing installation of Snow Leopard, or are you reinstalling?
    First be sure you have everything on your system backed up. Then reboot with the Command-R keys held to get to the OS X Lion recovery volume. In here, select Disk Utility and use the First Aid tab in here to run a verification on your boot drive. If there are any errors, fix them and then try the installation again.
    The next step would be to format the drive, so with your backup secured, use Disk Utility's Erase tab to re-format the drive to Mac OS X Extended (journaled), and then quit Disk Utilty and attempt the installation again.

  • I recently repaired disk permissions on my mac HD and now my on-board speakers wont work, the icon is greyed out and only works when my headphones are plugged in.

    I recently repaired disk permissions on my mac HD and now my on-board speakers wont work, the icon is greyed out and only works when my headphones are plugged in

    Try to put your headphones several times in and out from your connection, might be the switch is stuck. Normally it should work again while trying to plug the headphones in and out!

  • Constantly repairing disk permissions for Spotlight to work

    I am constantly having to use Disk Utility and repair my disk permissions in order to get Spotlight to work. Often I'll type something such as an application and the only thing that will show up is the Definition from the dictionary.
    Repairing the disk permissions seems to fix the problem, but it doesn't take long before I need to once again go in and repair in order to get Spotlight working again. I've tried dragging the whole hard drive into the exclusions list and then removing it again so the index will rebuild. That also works but again only lasts a short time.
    Any help would be much appreciated!

    I hear a lot about 'defraggin' in Windows. Is there something similar in Mac, ie: is Repairing Disk Permissions something similar?
    They're entirely different things. A "defragment" operation moves files around to combine split segments of files and consolidate free space. A "repair permissions" operation examines the permissions settings of system files and resets any that seem to be wrong.
    Here's what Apple has to say about defragmenting a Mac disk:

  • What does the message "Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired" when repairing disk permissions?

    What does the message "Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired" when repairing disk permissions?

    It's just a status message, albeit a misleading one, and can be ignored.

  • CD Ejects with Error Code 9 - Repair Disk Permissions Greyed Out

    History:
    Superdrive 815CA Ejects Blank CD's to be burned w/ Error Code 9
    Exact Text:
    The Operation Could not be completed an unexpected error occured(error Code 9)
    The CD Ejects, but the Ghost Icon of the CD image would stay
    Plays previously burnt CD's/DVD's as well as market CD's/DVD's fine
    Went to Disk Utility
    Repair Disk Permissions(RDP) & Verify Disk Permissions(VDP) greyed out so you can'tclick them when I click on first aid
    The only time they weren't greyed was when I clicked to repair the Ghost Icon CD, of which the actual CD was ejected in the first place
    I cleaned the lens umteen million times - same problem
    I did the Hardware repair check w/the startup CD, same problem
    I bought a NEW frickin' Superdrive and installed it successfully- same problem
    I went to system preferences and selected the option to open the blank CD in I tunes.
    This worked for burning MP3's no problem
    HOWEVER it will not open in the finder, so I can't save any data from my desktop on to a CD/DVD, so my hard Drive is getting clogged
    Got a Hammer?

    I loaded at least 20 different BLANK CD's to experiment with.
    The same CD's which get spat out when I open it in finder, burn fine when i open them up in I tunes
    I've already bought a new drive and the same problem occurs as when i had the old drive (can't open in finder), so i believe the bad drive and bad CD premise has been troubleshot.
    It seems like it won't recognize the Drive or CD when i try to launch a CD from the finder
    The blank CD's burn music fine when I open it up in I tunes, but not when I try to open it up in the finder when i try to put data on the CD's.

  • 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.

  • Archive, Repair Disk Permissions, etc. problems

    I have problems trying to archive files/folders. I get an error message: "The archive's list of contents cannot be created." I tried repairing disk permissions and it would still have that error message.
    Later, I decided to try to use Onyx, however, I couldn't access it and suggested to repair disk permissions and restart Onyx. I did that it still have that message. I later tried in another account, then in Safe Boot in my primary account and nothing changed. I can't even uninstall Onyx unless I repair disk permissions.
    I seemed to have problems syncing my iPod Touch 2g with iTunes saying that it couldn't sync because there was another sync client. I'm not sure if this is also related.
    It seems like that there is a system wide problem.

    I did stumble over that same thread and attempted to follow it. Something didn't work. I wasn't sure where '/tmp' was and using Terminal to perform the operations somehow didn't solve it. After revisiting the thread you posted, I figured out what was tmp which was located on the Macintosh HD -there was /tmp. Then I followed the steps and voilà, the archive did work. Along with Onyx and everything else.
    thanks!
