Disk Keeps Ejecting Itself

I've got a dane-elect multi-card reader.
I insert my canon 7D's compact flash card, delete a single picture,
and my card is ejected. I tried verifying it in disk utility, it unmounts
and I get a message saying that the disk was not ejected properly.
I just did a verify disk again, got this as an error:
Verifying volume “7D”

any idea what could be causing this?

I'm assuming this is an external disk connected directly to your computer.  In that case, it's likely to be a loose or faulty cable connecting the drive to your machine.  When it wiggles a little, the connection gets lost.  (That also could cause corruption in your Time Machine backups when it happens in the middle of a backup...  better repair that hard drive using Disk Utility!)  You may be able to make it work more reliably by changing cables, or by leaving the machine untouched on a table or desk while the backups is running so it doesn't get bumped.
If the cable isn't the problem, it's possible the disk itself (or the enclosure it's in) is faulty, or that the port on your computer that you're connecting the drive to is damaged.

  • Mac mini mid 2010 hard disk keeps ejecting itself

    My mac mini is set up with two sata disks installed, one is a 128 ssd and the other a 1tb hdd.  Since installing mountain lion, the hdd keeps ejecting itself, and i get a message saying - this hard disk was not properly ejected. then i wont find the disk in finder, or disk utility!.  I then have to remove the hdd from the mac mini and plug it into a usb caddy, which finds it no problem, and then when i put it back in the mac mini, it works again!! so the disk is not faulty i dont think.  It then works for a period as random as a few hours, to a few weeks and then i will randomly get the "this disk was not ejected properly" message and it has again dissapeared.  I use the mac mini as a media centre and it isnt really being pushed hard when the failure happens.
    Anyone have any ideas as to whats wrong?

    Hello, Sorry for the late reply.
    When i open console after the ejection i get the message:
    01/11/2012 22:32:42.000 kernel[0]: Failed to issue COM RESET successfully after 3 attempts. Failing...
    01/11/2012 22:32:42.000 kernel[0]: disk1s2: no such device.
    Hope this gives a clue, i'm tearing my hair out over it.  there is absolutely nothing wrong with the disk itself.
    If i do a full shutdown and restart, it finds the disk again no problems, but if i simply choose to restart from the menu, it does not find the disk again.
    Thanks for any help you can give on this.  I have only been experiencing this issue since i upgraded to mountain lion.

  • Memory card keeps ejecting itself

    Dear Apple experts,
    I have had an iMac with OS x 10.6.7 for a year now and for the last 2 weeks, whenever I connect a memory stick pro duo via a memory card reader, the card keeps ejecting itself every few seconds and an error message comes up "disk drive not ejected properly.
    I have tried changing the cable, the memory card and the reader but the problem persists.
    Please could you advise?
    Many thanks.

    try reformatting the card using your camera
    and restart your computer

    PS - Note that we are not Apple experts - we are Mac users just like yourself who use iPhoto

  • External SSD keeps ejecting itself

    Hi, i have a big problem, so any help would be really appreciated!
    I bought a SSD (Samsung 840 non-pro) for my macbook pro and I'm trying to clone my hard drive to the SSD. The ssd is connected per USB in an external case (http://www.amazon.de/gp/product/B008...ls_o02_s00_i00).
    Problem is that whenever I try to, the SSD keeps ejecting itself all the time, so the process of cloning aborts . Any ideas on what I could do? Please help, I'm pretty desperate by now, thnx!!

    The USB port is not providing enough power to keep your external drive running. This problem happens often. Your best bet, and a permanent fix, is to get a powered USB hub. Should not cost more than $20.
    The hub is plugged into the wall outlet for power. It is connected to the MBP with a USB cable. All your USB devices are then plugged into the hub. I use a 8 port D-Link hub. Have had it for more than 6 years.
    Post back if you need more info.
    (What I do not know - have never tried it - is whether I can boot from a drive connected via a hub.)

  • Having problems with copying the OS X to new SSD - SSD keeps ejecting itself

    I recently bought an OWC 6G Mercury Electra 240GB SSD and a data doubler for my early 2011 MBP. I replaced the MBP's optical drive with the old HDD and installed the SSD to the main HD bay. After erasing&varifying the SSD I started cloning my old system to the SSD. This is when the problems started. The SSD keeps ejecting itself everytime I try to copy something to it or when I try to varify it. My OS X is 10.9.2. Any suggestions would be appreciated. Thanks!

    There is a recall on the 15"
    Apple Recall
    https://www.apple.com/support/macbookpro-videoissues
    Are you using Carbon Copy Cloner or Super Duper? Did you try cloning from an external USB? or to one holding the SSD?
    If the latter is successful, that would point to the SATA cable being faulty.
    It does seem that SSDs are more sensitive to a defects in SATA cables than HDDs are.

  • Disk Drive ejecting itself

    My Time Machine disk drive has been "ejecting" itself since I installed Snow Leopard. I'm not unplugging it, or turning it off. I'm not touching it.
    I'm getting the following error message:
    "The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off."
    My question is why would a disk drive be "ejecting" itself. I've turned off the auto backups, and unselected the drive as the backup disk. It is still "ejecting" itself which leads me to believe the problem isn't with Time Machine but with something else - something connected with Snow Leopard because this wasn't happening five days ago before I installed SL.

    Does your external drive have its own power source or does it receive its power over the data cable?

  • SSD keeps ejecting itself

    My Crucial 256 GB SSD has been excellent as the boot drive in my Mac Pro 3,1 for almost a year. It seemed to handle all the OS upgrades with ease and ML was humming along nicely. Until about two days ago when I started getting beachballs every hour. I had to manually power down and restart to get back to work.
    At first i suspected ML and found a thread here in which others were complaining about having to manually shutdown and restart. So I thought it must certainly be some corrupted bit of ML. On further investigation, I found a bunch of folks out there with similar SSDs that were mounted in Icy Docks like mine. Aha! So I removed the drive and took it out of the icy dock then mounted it via an external drivedock firewire gizmo. It ran longer before ejecting, but eventually it did eject itself.
    Disk Utility found something it didn't like and repaired the drive but within 2 hours, it had ejected itself again. I have a new drive and new sled on order. However, I'm curious if anyone might have an idea about what (if anything) drove the SSD over the edge. What have I missed? Are SSDs and Mac Pros not meant for each other? Is there a ML connection?
    Thanks in advance,
    T-Ray

    How full? how about just image and erase and restore instead? CCC
    Are you using TRIM Enabler? 3rd party of course.
    m4 threads were "popular" awhile ago (May/June) when they popped up almost daily - mus have been Memorial Day sale @ Newegg.
    Firmware of course is first thing. There was an update very recently.
    There was a bug in SandForce firmware on some models, not Crucial but amazing that here we are 4 yrs and every year, every new model that comes out, some issues and "field testing."
    Definitely think some designs of Icy Dock don't fit right.
    I would recommend in order: Samsung 830 #1 even if Apple was not now using them in their new Macs; Intel for great support and ease of firmware updates and testing they did; then one of the Marvell or top quality SandForce. Crucial m4 gets good grades and performance on PCs - just seeems like Mac w/o native TRIM means BGC works harder and not as efficient.
    And of course you are using it on an SATA2 bus so while still good, it is hampered a bit.

  • Please help! 1TB SSHD drive in my optical bay keeps ejecting itself.

    I recently purchased a 13in macbook (non-retina, build 13e28), 500gb HD with the optical drive running the latest version of Mavericks 10.9.4.  I decided to install a Samsung SSD (120gb) along with a 1TB Seagate SSHD (a hybrid SSD).  My intention is to use the SSD for startup and for all my apps and to use the SSHD for storage of my music.  I have all my music from my 2008 macbook in an external disk and while I was transferring all my files (music, movies, pictures, documents, & downloads) the SSHD ejected on its own and I was prompted with a small window that said "Disk Not Ejected Properly - Eject "SSHD" before disconnecting or turning it off".
    I've rebooted several times and even re-installed the OS on my SSD to see if that would fix anything.  I also verified/repaired disk/permissions on the SSHD and it still keeps ejecting the disk within 2 minutes of re-booting.
    Can someone please help me resolve this?  Thank you!

    Check the specs for storage of your macbook. It probably can only handle up to 750 GB.

  • Help getting 200GB file off seagate drive that keeps ejecting itself

    here is the problem...
    I have a G5 running 10.5.8
    I have a Seagate Freeagent drive 1.5TB that keeps going to sleep and ejecting itself....
    I have an iPhoto file that is in excess of 200 GB.
    I want to get it OFF this drive and move it to a stable drive - but every time I try to copy/transfer it the drive ejects...
    How the heck do I move the iPhoto file off this drive? there seems to be NO fix for the seagate issue.
    HELP! thanks,
    Jen

    You won't like or want to hear this, but I would never buy name brand external drive cases like Seagate or Maxtor, too many problems, want to avoid proprietary and other issues. And they are troublesome.
    iPhoto files are package bundles - just a whole lot of nested files and folders, not a single 200GB file.
    Clone the whole drive or portion thereof using software backup or cloning software.
    Would be nice if you could just remove the SATA drive and pop it into the G5 or into another FW case.

  • Trying to Clone new SSD, keeps 'Ejecting' itself mid-copy

    I have bought a Crucial M4 SSD Sata 2. I am using a macbook 5.1 Mid 2008 Unibody, running mountain lion.
    I downloaded 'SuperDuper' and have renamed my SSD to 'My Mac'. I Then attempt to copy all files using SuperDuper, from my old HD to the New, using the selection 'Backup - All Files'
    It starts to copy as normal, all looks like its going well. Then i come back around 30 mins later and the disc has Ejected itself and of course the process then fails.
    I have attempted the process around 5 times now, and happens each time. I dont know if it is a connection issue, or a software/firmware issue.
    To Add, I am Connecting the SSD externally using a SATA Cable.
    Has anyone had a similar issue, who may have a solution?
    Kind regards.

  • Leopard disk wont load, keeps ejecting itself.

    I got the disk today and I go to load it and it does nothing, I can hear it spinning then ejects it back out. Nothing appears on the desktop. I went through the trouble shooting and found nothing that would help me. I have Tiger OS X 10.4.11. PLEASE HELP ME!

Once its here I will be able to check the disk to see if it works on hers. And I dont have an apple store near by, closest is a few hours away.
    Acutally the DVD might not work on her computer since the computer already comes with Leopard CDs specifically created for her machine.
    Also, girlfriend's boyfriends do not qualify for the use of a Family Pack, until they get married.
    The license is quite specific about who can use the Family pack. Friend do not count.

  • Disk keeps ejecting

    My son bought the family pack snow leopard and every time I put it in the disk drive, it ejects back out and won't let me install.

    HI,
    Make sure the disk is free of fingerprints and smudges.
    How to clean a DVD
    Repair disk permissions and then see if the Mac rejects the disk.
    Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.

  • Why does my disk keep ejecting

    when i insert my disk into the computer it reads it then automaticl ejects the disk.  How do i make the computer ready the disk.  I have an imac early 2008 with intel core i2 adn 4 gb of ram

    If it is just that one disk, then it may be dirty or scratched. Use a clean damp cloth to gently wipe off fingerprints and dirt in a radial (center to edge) motion, not in a circular motion.
    If this happens with all disks, your optical drive may be broken. You would then either need to replace it or obtain an external optical drive.

  • Deleted safari on accident and reinstall disk keeps ejecting

    ??

    I dont even know how or what my wife did, but not only safari is gone but several other programs that i dont even know.  i just see several blank spots in my applications box, the terminal is even gone!
    I am going to do a time machine back up for my pictures and music and than try the reinstall disk again. What are my risks here? i dont want to take it back to original settings, will there be options?

  • Keeps Ejecting PC Disk & Apps Sometimes Cover Desktop on Launchpad

    Hi. I'm loving OS X Lion and I like the gesture to bring up Launchpad and I can't wait for all apps to have fullscreen abilities so you could just swipe between apps. I still believe the gestures that Lion replaced specifically the reverse scrolling and on finger swipe is only intuitive if you're actually using a multitouch screen like maybe an angel adjustable multitouch iMac or multitouch Cinema Display which hopefully will be come out in the near future (with option to use the usual keyboard, mouse, trackpad) but I'm kept it on default, maybe it'll grow on me and may actually be more intuitive even for the desktop. I also can't wait for all apps to use Versions. I do hope they change their theme, the colors are too subdued. It's a subdued Aqua. Launchpad's metallic icon is good. I think Apple should change the theme to "subdued Aqua" to anodized aluminum to give icons and UI elements more distinction. Sometimes the color is too subdued, you think it's been click or is not available.
    After upgrading to Lion though, sometimes the apps in Launchpad would cover the Desktop on top. I'm not sure if it's because my apps is always maximized (not really in fullscreen mode) or it's a glitch or a bug. If it's not a glitch, what's the solution for this?
    Also, I'm not sure if it's Windows on Boot Camp or Lion but my PC DVD keeps ejecting itself which it hadn't done before. Any solution for this as well?
    Thank you in advance.
