Blue screen, disk utility says ok, backing up question..

A friend has an iMac G5 that is just out of warranty (10/08). It hangs on the blue screen. I've tried using their original start up disk and was able to access disk utility but it said all was o.k. The Disk Warrior version I had was unfortunately too old to use (used it on my PowerMac G4). It would not start up in safe mode. My question is this: if its the logic board, how can they access their hard drive to recover their info without paying someone to do it? I had a logic board issue with an iBook G3 and was able to clamp the left front corner of the book (while open of course) which allowed me to start up the computer and recover my info. Can I do the same thing with this iMac??

Have you tried accessing it in Target Disk Mode? I don't think clamping the corner applies to desktops.

    Reinstall OS X:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

    Had the same problem, finally realized that the FileVault Encryption was struck at 19%. Speed back up to normal after I disabled FileVault using terminal command - sudo fdesetup diable
    To check whether the FileVault is the culprit, go to System Preferences --> Security & Privacy --> FileVault to see if encryption is in progress.. For me the blue bar was less than a quarter with status 'estimating time remaining'..
    Then open Terminal and type in: sudo fdesetup disable
    It will then ask for the admin password (to be it asked twice), then it was disabled... Back to normal life again..
    Here is my terminal log for reference:

  • When i take photos or videos on my ipod touch with the camera, then i plug it into the computer to sync, the computer shuts down and this blue screen comes up saying "an error has occured" and a heap of other stuff.

    When i take a photo or a video using the camera on my ipod touch, the computer (windows xp) shuts down and a blue screen comes up saying "an error has occured" and a heap of oth stuff in white. It doesn't wipe the memory or anything off the ipod. Whenever i sync my ipod without photos or videos it works fine. It also doesn't mind me taking photos off itunes to put on the ipod. I have had a look around and a couple of people say reinstall itunes, but i don't know if i will lose all my songs and apps. Any suggestions of help?

    Removing all Apple related software and reinstalling iTunes should bring all needed drivers back: Removing iTunes, QuickTime, and other software components for Windows XP
    Also check for new driver updates for Windows, especially if you have a webcam installed.
    iTunes Store purchases or songs imported from CDs are saved in your My Music folder by default and are not deleted by removing iTunes. While it is highly unlikely that you will lose any contents of your iTunes Library when following these steps, it is always a good idea to ensure that your iTunes library is backed up. If you're unsure how to backup, see iTunes: Back up your iTunes library by copying to an external hard drive.

  • Disk Utility says of USB Drive - "This partition can't be modified" "This disk is not writeable and cannot be partitioned"

    Several months ago I bought a 64GB PNY USB memory stick to transpord data quickly.
    It seemed to work fine.  I could format it as a Mac partition and use it.  I hardly ever need
    it so I just put it away.
    Today I wanted to use it to put a file on and take it to the Kinko's/FedEx to print, and I
    find I cannot mount it on any of my computers, iMac, MacMini or MacBookPro.
    In Disk Utility virtually everything is greyed out.
    Disk Utility says: "This partition can't be modified" "This disk is not writeable and cannot be partitioned"
    If I try to mount it, it says "This disk cannot be mounted"
    There is no physical read-only switch or setting on the disk that I can see and it is very small.
    I has a Mac OS installed on it, so I wonder if that is a problem?  I should be able to write over that
    or reformat it I would think.

    Thanks for these replies. 
    I've got regular time machine backups and just backed up some of my data by copying some key folders to an external drive.  I'm bit paranoid about backup integrity and would ideally like to do another full backup to a different drive using a system other than time machine, in the event that something goes wrong with the time machine backup.  Any recommendations on good and affordable backup software to do a backup of my TM backup?
    One other question: I seem to encounter problems like this pretty frequently.  I'd say once a year or so, my drive fails completely or gets near enough to failing that I have to wipe and restore.  (I've never had a TM backup fail to work, though the last go around there were some hiccups which has led to my backup paranoia.)  I've had this happen on multiple computers, so I'm becoming pretty convinced that the problem lies somewhere in my data.  Is it possible (even likely) that there's something in my data causing this recurring problem?  If so, is there anything I might be able to do to try and pinpoint and address this problem?  I'd love to go one year without having to wipe/restore my machine!
    For a while I thought I just had bad luck.  But I think this is like the 4th or 5th time this has happened in the past 4 years and every time, I'm restoring from a backup, so I come back with the same data.  It's the one constant since I've had 3 different machines over this same time period. 

  • I have to replace my hard drive as it is failing, I'm away and just bought a new external HD for backups,,only problem is it is fsiling to backup without a reason. Disk utility says ex HD is ok. I need to backup before i get it repaired. Any Advice?

    Hi my hard drive is failing and I'm overseas in Thailand. I bought a Buffalo 1TB to back up my mac 13inch HD version 10.6.8, only problem is it wont back up. Disk Utility says ex HD is fine. I need to backup before I take it for repairs. What can I do? Thanks advice appreciated. NL

    I think we both had our wires crossed a little.
    Then just go ahead and clone your internal drive to your Buffalo. You are not going to use Time Machine, and you do not have to partition it. So ignore all that stuff I posted. Let me start from scratch.
    First check that your Buffalo drive is partitioned GUID and formatted Mac OS Extended, Journaled. So open Disk Utility, select the topmost entry for the Buffalo drive. You should see something like this:
    I have selected the entry of my CalDigit drive.  Note that the Partition Map Scheme is GUID. Now, select the volume (mine is "System Backup."
    Here you see it is a Format type of Mac OS Extended, Journaled. If that's what you see then you are good to go.
    With Disk Utility still open:
    Clone using Restore Option of Disk Utility
      1. Open Disk Utility in the Utilities folder.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Select the destination volume from the left side list and drag it to
          the Destination entry field.
      5. Select the source volume from the left side list and drag it to
          the Source entry field.
      6. Double-check you got it right, then click on the Restore button.
    Destination means the Buffalo drive. Source means the internal startup drive.

  • Hi, how do I manage storage? Disk Utility says "other" is taking up most of my storage but I don't know where to find "other".  Please help!

    Hi, how do I manage storage? Disk Utility says “other” is taking up most of my storage but I don’t know where to find “other".  Please help!

    For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
              iPhoto ▹ Empty Trash
    Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
    When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as  Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
    See this support article for some simple ways to free up storage space.
    You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
    Deleting files inside a photo or iTunes library will corrupt the library. Changes to such a library must be made from within the application that created it. The same goes for Mail files.
    Proceed further only if the problem isn't solved by the above steps.
    ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
    Back up all data now.
    If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
    Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
    Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper 2>&-
    sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective 2>&-
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad and start typing the name.
    Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
    The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
    I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
    When you're done with the app, quit it and also quit Terminal.

  • Xserve RAID: Server Monitor says degraded, disk utility says mirror FAILED.

    Xserve Quad Intel 4x2GH
    4096 GB RAM
    OS X Server 10.4.11
    Xserve RAID 7TB 14x 500 GB ADM via dual fiber channel, Mirrored, 3.5 TB array.
    Flashing yellow indicator light on Xserve this morning. Investigated and found that RAID Admin says everything is OK, all 14 drives normal.
    RAID Admin log says :"4000 1 Wed Apr 08 09:37:59 EDT 2009 Disk 2 Failed To Respond. Retrying. RETRY COUNT:0 LBA:0x1C700"
    Under the RAID tab, Disk utility says: "Mirrored RAID Set: Degraded" and "Disc2s3: FAILED"
    All LED's are solid green across the front of the ADMs.
    Since all my drives are reporting OK, could this be a problem with the Fiber Channel interfaces?
    Should I just backup (again), shut down and rebuild the mirror using Disk Utility?

    Hi Kappy<
    I am trying to migrate user data from a RAID - 1 slice from my old PowerMac G4 running OS X 10.4.11 to my new MacBook Pro running OS X 10.5.4 by reading a mirror RAID slice from my old Mac that is mounted in an external drive enclosure and connected by FireWire.
    The problem is that the new Mac cannot read the old Mac disk, it never shows up on the desktop, or comes up as available when trying to use Migration Assistant. Then, if I go into Disk Utility, the external RAID slice shows up briefly with a locked yellow padlock beside it, then I suddenly get the window shade of death, and have to hold down the power button to reset/restart my MacBook.
    Why can my new computer not read my old computers disk, and how can I change permissions, or make the old drive readable by the new mac.
    Regrettably I am away from the original Desktop, and cannot load the old drive back into it, connect the two machines and migrate that way. My only option for reaching my necessary data is to retrieve it off the drive I have with me.
    Thanks in advance for any help you can offer.

  • Disk Utility says everything's fine, but Install disk doesn't find my internal drive as a possible destination. When I startup with Command   S, I get a looping "cannot mount errno = 19" message.

    Disk Utility says everything's fine, but Install disk doesn't find my internal drive as a possible destination. When I startup with Command + S, I get a looping "cannot mount errno = 19" message.
    Problem started when I used Tech Tool Pro 6 to "de-fragment volume". Had to cancel that process before it finished because I ran out of time. Thereafter, when I startup my machine normally, I get the gray Apple logo at first, but it changes to a prohibited symbol (circle with a slash thru it) and hangs.
    When I startup holding the Option key, I can see my internal drive, but I get the same results as above.
    When I startup using the MacBook OSX Install DVD, it does not find my internal drive as possible destination.
    When I startup using the MacBook OSX Install DVD and then run Disk Utility, it finds my drive, allows me to "repair" and says everything is fine.
    When I startup with Command + S, I get a looping error message "errno = 19" and cannot stop it to do anything else.
    When I startup from Disk Warrior v4.4, it does not find my internal drive to do any repairs.
    When I startup from Tech Tool Pro 6 and run the "computer check" diagnostics, everything passes but the Volume Structure, which fails at "Volume Extents (B-tree)." When I use TTP's "Tools" option to run "volume repair" it will show my internal drive and allow me to click the GO button, but nothing happens and nothing changes.
    I have a Time Machine backup on an external USB drive, but for as long as the internal drive doesn't mount, I can't use the backup to restore.

    It's a false report and should be ignored.
    I would not rely on TT as I've already said earlier even before Grant posted similar advice.
    I really think the Rigid Disk Block may be corrupted. This holds the partition map and could prevent a volume from being unmounted. Unfortunately, there is no way to fix that without repartitioning the drive which will remove everything. So, before going down this road I hope you have backups or can make a backup.
    Drive Partition and Format
    1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. Quit DU and return to the installer.  Proceed with reinstalling OS X.
    5. Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • HD crash.  Disk utility says invalid node structure, invalid record count.  Disk utility cannot repair. Now what?

    My hard drive crashed.  The disk utility says it can not repair.  I tried to boot in safe mode but I stopped after 10 minutes.  Is that impatient or how long can it take?
    I have the installation disk but doesn't that erase everything?

    I have never bought a new computer from Apple so I don't know the details of what is covered by the warranty.  You can try taking it to the Apple Store and they may have a copy of DW they can run.  Or maybe not and they will just wipe the drive and reinstall the OS for you and if you haven't made a backup before they do that then tough luck.  I'd check first!
    If you buy Diskwarrior on DVD it will boot the computer.  I think Apple Stores carry it, but you can also buy it directly from the vendor. I also don't use Lion OS so I don't know the details.  You may be able to get their download version and boot from your recovery partition, then run it without a DVD.

  • USB Hard Drive that Disk Utility says it can't unmount

    I have a 93.2 Gb Hard Drive (from an old G4 PowerBook) inside an enclosure with USB connection. While trying to recover data from it using Data Rescue (on a G4 PowerBook), Data Rescue II hung. After restart, the USB Hard Drive can not be read at all. Disk Utility says it can't repair it or erase it because it can't "Unmount" the disk. What can I do with the USB Hard Drive?

    try this: open system preferences/spotlight/privacy and drag that external into spotlight privacy then try Disk Utility.

  • What does it mean when you computer crashes and when you turn it back on it shows you a blank blue screen with a little folder and a question mark in the middle?

    What does it mean when you computer crashes and when you turn it back on it shows you a blank blue screen with a little folder and a question mark in the middle? It's a old imac from 1997.

    I don't have original discs that it came with.
    Then you still can use the second option with the keyboard combo I posted, called "resetting the PRAM."
    Also when you way hold the c key down do you mean turn computer off and turn back on holding the c key?
    Yes, or you can simply restart. As you don't have the CDs, this isn't on the plate any more.
    The internal backup battery is not expensive and, in most iMacs is user-replacable. If yours has a tray-loading optical drive like this one:
    it takes a major teardown to replace the internal battery. If this is the case, you'd be better off to leave the computer plugged in all the time; that eliminates the main reason for having a working battery.
    If it has a slot-loading optical drive like this one:
    things are much easier. The battery is visible through the RAM access door on the bottom of the computer case. The manual:
    http://manuals.info.apple.com/en_US/iMacG3_2000UserManual.PDF
    has sketches of how to access the RAM and therefore the backup battery. Unfortunately, the pdf on the manual goes up sideways on-screen and the RAM instructions are pretty deep into the manual. It's probably easier to scroll (for a while) to the section on adding RAM and print the applicable pages.
    When you work on the battery, some sort of non-conductive pliers or large tweezer or forceps help unless you have tiny fingers. Make sure to note the polarity of the old battery and install the new one in the same orientation.
    The battery itself is readily available. If price is no oblect, you can get it for a small rasom from Radio Shack Store ("Tandy" outside the US) as part number 23-026.
    Online, they are dirt-cheap even after adding shipping. I buy backup batteries form this outfit:

  • Disk Utility says "drive can't be repaired, disk and restore your backed up files."

    My Mac Book Pro froze yesterday and I had to force restart it. It had been showing me messages that my hard drive disk was full for a while and I was in the middle of transferring files to my external hard drive and I accidentally put a huge large file from my external hard drive into the trash on my laptop which makes me wonder if that means I added more GB to a computer that was already very full. Anyway, after freezing I restarted it and the desktop wouldn't load properly. The desktop picture was there, but folders on desktop did not appear, finder bar was missing and the dock was acting super slow and nothing worked when clicked on. Then the next few attempts were around the same result and eventually became stuck on the apple logo, spinning gear and a progress bar that was not loading at all.
    Here's what I've tried so far:
    Safe mode- nothing happens
    Command + R - I am unsure how to work this since I can't seem to find an internet connection when it prompts for one. None of the internet connections have much signal and my own information doesn't seem to load since the gear spins to find the internet connection name and password I typed to load it but can't seem to find it. Perhaps I have the wrong internet information, but I don't think so.
    I tried Command + S to use in single user mode and type in a command to help fix the drive, BUT, even though the black screen and white lettering mode did show up, it remained in a place where I was not allowed to type anything and the last thing written at the bottom of the screen was something about set up for bluetooth, I think. I tried this twice and both times it stopped in the same place and I could not type a command.
    Disk Utility using installation dvd to verify and repair disk. Verify says disk needs repair and then repair has some red colored phrases: Invalid volume file count. (It should be 786374 instead of 786274) Incorrect number of thread records. And there was another problem listed but I do not remember it. Then, near the end of repairing it says: "Disk Utility stopped repairing Macintosh HD." It tells me it couldn't repair the disk and that I should back up as many of my files as possible, reformat the disk and restore backed up files.
    That would be fine and dandy, but I have no idea how to back up my files and do all this. I have no idea how to exactly get the data off my hard drive. If someone does, please list a step by step guide for me on how to do so.
    I have an external hard drive and I tried plugging in and selecting the hard drive and making a "New Image" to copy to the external hard drive destination, but it just stops a few seconds into it and tells me there is an input/output error. I tried read only, read/write only, compressed options for making a copy and all yield the same result.
    In Disk Utility, I believe I have a partition -the Macintosh HD. I have listed on the left hand side: 320.07 GB Hitachi HTSS45.....etc. and below it in non-bolded, grey lettering it says "Macintosh HD."
    The Hitachi, when clicked upon, shows the S.M.A.R.T. status as Verified and the Macintosh HD doesn't show much in details except for "Not mounted."
    At one point, the Macintosh HD was in bold lettering and seemed to be mounted for a few minutes. When that happened, I was able to see the details reading: Mount Point: /Volumes/Macintosh HD, Capacity: 319.73 GB, Available: 11.92 GB, Used: 307.81 GB, etc.
    I'm getting nervous to keep turning on and off the computer on force start and shut downs, especially since I have been reading up that the longer the computer is on, the more the hard drive is in use and the more chance for it to start deleting or overwriting my files. Is this true?
    It's not mounted anymore since it was momentarily mounted. I just want to get my files off the disk and save them to my external hard drive. That is my main goal right now. What can I do?
    Thank you in advance for your help!

    If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
    There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
    1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”

    2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

    3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
