What can cause false "disk needs to be repaired" message?

Occasionally, when using OnyX or Disk First Aid, a message states to restart the computer, holding Command-R and to repair my disk.
Every single time, the disk turns out to be OK.
Question 1: Is this a false reading, or is the disk actually being fixed by the Control-R combination?
Question 2: If it is NOT a false reading, since my programs don't crash and I always shut down properly, what could cause the errors?
Regards
Macbook Pro 13, 10.9.4, 4GB RAM

Occasionally, you might have transient issues generate this message.
To know more about the condition of your hard drive, I'd run SmartReporter and look for errors:

  • Help: Disk Utility: Disks need to be repaired

    My MacBook Pro lately has been extremely slow and just constantly thinking and freezing.
    I ran the Disk Utility to verify the disk and this is what came up:
    "This disk needs to be repaired using the Recovery HD.  Restart your computer, holding down the command key and the R key until you see the Apple Logo.  When the OS C Utilities Window appears choose disk utility."
    So I did this step and went to repair it.  But when I said repair disk, it said that the disk seems to be Okay.
    Why does it say that?  How can I fix my computer, or do I need to go to the Apple Store.  Please Help.
    Thanks

    Looking at your top screenshot:
    That appears to be the NETWORK version of Disk Utility.
    From this I conclude your Internal Hard Drive was seen as failing, and it would not boot to the Recovery_HD partition on the Internal Hard Drive, and went for the Online/Network version of Recovery_HD (from the Internet) instead.
    I think you should take it in for service and expect that they are likely to replace the Hard Drive and give it back to you with a new drive with ONLY Mac OS X (no user files) installed.
    AppleCare warranty and SSD:
    Like most warranties, AppleCare covers defects in materials and workmanship. They will replace like-with-like, that is: they will give you the same drive or a slightly better one. I suggest you have it fixed and take advantage of whatever they will give you under warranty.
    Apple does not sell the 2.5" form factor SATA SSD notebook drives that would just fit into the same space as your internal drive. These are very popular with upgraders, and users find they are somewhat faster, run cooler, and allow the battery to last longer. You can always replace the spinning internal drive later with one more to your liking, and run the old one in an external enclosure for more on-desk storage.
    You do not void your warranty by installing an aftermarket drive such as an SSD, but the actual new drive would not be covered under the Apple warranty. (many Vendors warrant the drive separately for at least a year, sometimes longer).

  • Trash will not delete from trash folder! What can cause this effect?

    Trash will not delete from trash folder! What can cause this effect?

    u can actually force it to delete, oviously i assume you dont have the application or data etc open neware else?
    try restarting your computer, go into finder close all your open applications etc, servers, **** even clear your data in your web browser, do a disk utility check and verify your drives and repair em if nessicary.
    as chamar suggested look at http://www.thexlab.com/faqs/trash.html
    i had the same problem before but with a good 5-10 minutes of googling i was able to solve it..
    best of luck

  • Photoshop CS4 for Mac What can cause the error: Plug-in failed to load - NO VERSION

    With Photoshop CS4 for Mac I install the Kodak Plug-in DIGITAL GEM Airbrush Professional v2.1.0. When Photoshop starts I get an error:
    Plug-ins that failed to load:
       DIGITAL GEM Airbrush Professional v2.1.0 NO VERSION -  - from the file “DigitalAIRProv2.plugin”Flash:
       Connections
       Kuler
    This plug-in works fine on my Mac Pro with Photoshop CS4 and OS 10.6 but fails on a new Macbook Air.
    Reinstalling the plug-in did not make any difference. What can cause this error?

    Thanks Chris, That was my first thought too but this same plug-in works on another installation of CS4. This is a Mac installation and the plug-in is Universal so it should work. Is there any other possible cause for this error? Would Photoshop refuse to load a plug-in in a low memory situation?
    Also, The Flash extensions:Connections and Kuler are working OK, I just copied a little more out of the System Info report than I needed to.

  • Myfi is running very slow, what can cause this?

    Myfi is running very slow, what can cause this?

    Either a service problem in your area or a glitch/hardware problem on the Jetpack.
    To determine service problems simply travel to a different area and rerun your speed test.  If the problem persists then its a glitch/hardware problem on the Jetpack.  If not then its a service problem in that particular area that would need to be addressed by VZW or improved with the usage of antennas/boosters.
    When performance testing be sure to use a tool that is universal to better illustrate the problem.  For example a common utility is to speed test using www.speedtest.net.  Run this test a few times to build an average and then perform the same tests in a different location or after changing something around.

  • IPod Touch not recognized by ITunes, but IPhone is. What can cause only one device to not be recognized?

    I have tried reinstalling ITunes and resetting my IPod Touch. The computer recognizes the IPod Touch as a connected device, but ITunes doesn't. However, ITunes will recognize other devices that I plug in with the same usb cord. ITunes diagonistics only says that no device is plugged in whenever the IPod Touch is plugged in. What can cause this combination of problems, and how could I get around it?

    If you have iTunes 11 on the computer and are using the same cable that works with the iPhone then:

  • Yosemite won't install on my computer because the disk needs to be repaired. I verify, it indicates repair is needed but then the repair disk button can't be clicked. I tried to start in safe mode but it just froze.

    I'm to install Yosemite but it tells me the disk need to be repaired. When I verify the repair disk button remains pale and in-clickable. I'm not sure which version of OS X I'm running but I do know I forgot to back up. Help me o-message board, you're my only hope!

    Welcome to Apple Support Communities
    First of all, open the Apple menu -> About this Mac, and tell us what OS X version you have.
    If it is 10.6.x, you need the Snow Leopard DVD. Insert it, press the C key while your Mac is starting up, choose your language and go to Utilities menu (in the menu bar) -> Disk Utility.
    If it is 10.7.x or higher, hold down Command and R keys while your Mac is starting up to boot up in OS X Recovery, and open Disk Utility.
    After opening Disk Utility, choose your OS X partition in the sidebar (it is usually named "Macintosh HD") and press "Repair Disk". When it has finished, restart your Mac, make a backup of your files and try upgrading to OS X Yosemite.
    The backup will help you in case you decide to go back to the OS X version you are using now. If you cannot make a backup and the disk repair does not work, you will have to format the hard disk.

  • Mac pro monitor has a shadow in its center. Does anybody know what can cause that?

    Last day my mac pro showed a shadow in its display center. Does anybody know what can cause?
    I use to use it a litle, cause i'm new on macs and still use pc based on windows.

      Who made the monitor?  Is it even Apple?
      If you have the right connections, try swapping out the monitor with your PeeCee monitor and see if the problems stays or goes.   But does sound like a monitor issue.  But then, hard to know what you mean by shadow...

  • What can cause ctm_config.properties to reformatted ? LMS 3.2 solaris10

    The customer observed the same error mentioned in this thread:
    https://supportforums.cisco.com/message/3038760#3038760
    When running a quick report in Campus Manager (User Tracking > Reports) the following error appears:
    Application error: URN_NOT_FOUND : urn "ogs_server_urn" : Not found !!.
    Also, the reason here was the same, a config file with with wrong content:
    NMSROOT/MDC/tomcat/webapps/cmapps/WEB-INF/lib/ctm_config.txt
    Interestingly, the file was touched when a specific job started. So I assume that this job somehow scrambles up that file.
    the content of the "wrong" file was:
    ================

    If I remember well this job was of the type "Switch Port Report-Switch Port Summary". But I could not see this job. The reason for this could be that there were a huge amount of jobs listed in  CS > Server > Admin > Job Browser: more then 30 000 history entries.
    After cleaning up the number of history jobs, the same error appeared again a few day later. What can cause this strange error ?

    I am still confused with this error...
    after the first occurence of the problem I added the line (DYNAMIC_PORT_ALLOCATION=0) to ctm_config.txt as you suggested, restarted the service and the problem was gone;
    is it necessary to do this also for the file in the campus path?
        /opt/CSCOpx/MDC/tomcat/webapps/campus/WEB-INF/lib
    a week later or so the customer said that the problem reoccured without corruption of ctm_config.txt - could this be possible?
    As I described above, according to the timestamps of ctmregistry (in cmapps) it was not rewritten after dmgtd restart - ok - but why was it possible to generate the UT > Reports without a problem first an later not?
    this is what I observed with the last test:
    after deleting ctmregistry in both directries it was only recreated in
        /opt/CSCOpx/MDC/tomcat/webapps/campus/WEB-INF/lib
    around 20 mins afer ANIServer start time and it did not get created in
        /opt/CSCOpx/MDC/tomcat/webapps/cmapps/WEB-INF/lib
    although, the reports in UT > Reports > Report Generator are running fine
    I assume ctmregistry in cmapps will get created on the first request but this is not the task of generating the report. Instead I think another tasks/action creates this file but when it exists the Report Generater makes use of it. I observed that with a bad ctmregistry file and a good ctm_config.txt in
        /opt/CSCOpx/MDC/tomcat/webapps/cmapps/WEB-INF/lib
    the Device Selector for UT > Reports > Report Generator did not show any Devices...
    so I am a little confused about this behaviour...
    Is there/will there be a patch available for LMS 3.2 that prevents ctm_config.txt to get corrupted? It is a config file - shouldnt it be opened read-only by any LMS process?

    I cannot control the sensor on my Mac, it moves by itself, and opens different pages. What can cause this problem? please help me.

    There are several possible causes for this issue. Take each of the following steps until it's resolved.
    1. Follow the instructions in this support article.
    2. Reset the System Management Controller.
    3. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
    4. A swollen battery in a MacBook Pro or Air can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced.
    5. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built in trackpad of a MacBook to  behave erratically. If you're using such an adapter, disconnect it and test.
    6. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
    7. If none of the above applies, or if you have good reason to think your computer is being controlled remotely, remove it from the network by turning off Wi-Fi, disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop immediately, you should suspect an intrusion.

  • "Error: disk needs to be repaired.. "

    When I run disk utility I got the message "Error disk needs to be repaired.." In addition i got the errors:
    Incorrect number of file hard links
    Volume bitmap needs minor repair for orphaned blocks
    Invalid volume free block count
    When I restart and after command R, I run the Disk utility but then it shows no errors, what is the problem then?. Thanks

    Try removing these one at a time:
         /Home/Library/Containers/com.apple.iPhoto/
         /Home/Library/Preferences/com.apple.iPhoto.plist and com.apple.iPhoto.LSSharedFileList.plist
         /Home/Pictures/iPhoto Library
    Place one at a time into the Trash but do not Empty the Trash. Try to open and use iPhoto. If iPhoto works then the item you put in the Trash is the cause of the problem. If the problem turns out to be iPhoto Library, then you will need to look to a third-party utility that can fix the library.
    To find the invisible library folder:
    Exposing the /Home/Library/ Folder
    Pick one of the following methods:
    A. This method will make the folder visible permanently. Open the Terminal application in your Utilities folder and paste the following at the command prompt:
    chflags nohidden ~/Library
    Press RETURN.
    B. Click on the Desktop, press the OPTION (⌥) button, select Library from the Finder's Go menu.
    C. Select Go To Folder from the Finder's Go menu. Paste the following in the path field:
    ~/Library
    Press the Go button.

  • Two HDDs saying 'disk needs to be repaired' at same time / external drive.

    Hello there,
    I have had a strange problem within the last couple of days. Both my iMac which I use at the office and my MacBook Pro have had problems writing to an external FW800 drive which I work directly off [the error comes when I try and save from an application / try and copy / rename files on the drive]. The message is that either a problem occurred or that the filename is too long [it isn't]. When this happens I try and restart, but the disk causes the finder to hang.
    This has happened with both machines [the iMac and MBP], and as a consequence - when I run disk utility on each machine, I get a message that the disk needs to be repaired:
    Error: 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.
    Has anybody had similar problems? Is this a coincidence? Or would blame point to the external drive?
    The drive is a Lacie Rugged 250gb FW / USB. It does get rather hot - don't know if that should affect anything.
    Many thanks,
    Ben

    Could this problem in turn cause the internal HDD problems I've been experiencing with the iMac and the MBP after the Lacie becomes unresponsive?
    Or, your internal HD problems are transferring to the Ext.?
    It's hard to say. I would at least do the following basic repairs to all your hard drives.......
    Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
    You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job.
    After that Repair Permissions.
    No need to report Permissions errors....we all get them.
    Think it might have to be returned...
    Yes I would return it just cause of the heat issue alone.
