    How To Properly Eject a Hard Drive

    I have a USB hard drive attached to my Ubuntu 9.04 computer. There is no "eject" option when I right click on the USB hard drive.

    There is an unmount option. After I unmount how do you power down the USB powered external hard drive? I'm not going to pull the plug and damage the hard drive.

    As long as it's unmounted it can be unplugged.

    Re: How To Properly Eject a Hard Drive

    Thanks for the reply but Western Digital's own website explains that the USB hard drive should be powered down before removal from the computer. How can you power down the USB hard drive from within Ubuntu 9.04?

    http://wdc.custhelp.com/cgi-bin/wdc....i=&p_topview=1

    Question
    Why doesn't my external hard drive power down when I use the Windows Safe Removal tool in Windows Vista?

    Answer, Problem:
    A USB connected external hard drive may not shut down properly when you use the Windows Safe Removal tool in Windows Vista.

    Cause:
    This is a known issue caused by Windows Vista and USB external devices.

    Resolution:
    Microsoft knows of this issue and is currently working on a patch or hotfix. For more information about this issue, please contact Microsoft for support at http://support.microsoft.com.
    As a workaround, you will need to shut down the computer system with the hard drive attached to safely eject/dismount the hard drive.

    It's not so easy. External HDD with own power supply have to be first unmount and stop. I have the same problem. Anyone found solution?

    To find its designation you could do this in Terminal
    Code:
    sudo fdisk -l
    Yes I'd also suggest you unmount it first then, if it's /dev/sdd then do this
    Code:
    sudo eject /dev/sdd
    You can also use that for a DVD/CD-ROM too, and if you want to close the CD tray
    Code:
    sudo eject -t /dev/sdd
    Hardware: Intel Core 2 Quad 2.4GHz/ 4GB DDR2 800MHz RAM/ nVidia 9600GT 512MB/ Gigabyte GA-P35-S3G
    That fuzzy feeling in your head is your brain working, thanks to Linux!

    Talking Re: How To Properly Eject a Hard Drive

    I did follow instruction by Sergei.

    I have to add:
    1) You need first install sdparm.
    2) If your device has name/mounting point two elements e.g. "My Book", you have to change mounting point to one element name (no space) e.g. "Book" or "MyBook".
    Them just follow Sergei's instruction. It works well just take some time to stop 500GB WD HDD.

    PS.: I did test it on two devices:
    1GB USB Scandisk (flash)
    500GB Western Digital My Book (HDD)
    Both USB 2.0

    In Karmic there is no more such a problem. Enough to install gnome-mount:
    Code:
     sudo aptitude install gnome-mount
    This add to context menu option to safe remove (alongside of unmount) volume.

    Frankly if the filesystem is not mounted, I fail to see what harm it could possibly do to unplug the usb drive. USB is hotpluggeable after all, only mounted filesystems are not.
