External hard drive does not shut down

Hello, When my mini mac goes to sleep my samsung external hard drive does not shut down or dismount properly. when i wake computer i have a error message stating improperly ejected hard drive. It also does not reconize HD until I disconnect and reconnet??? PLEASE HELP Thank you

My Mini was doing the same thing until I reset the PRAM. With four external drives. They would stop inadvertently with an "improperly ejected" error. Granted two of the drives went bad (6 and 7 years old) but a brand spanking new Seagate and a 3 year old Hitachi drive doing the same. Haven't seen the error since resetting the PRAM.
If you don't know how to do that, Reboot while holding the Cmd+Opt+P+R keys until your hear the startup chime three times and then release the keys.

  • External Hard Drive does not mount

    My 2TB external hard drive does not mount and I cannot get it to.  Have tried turning the hard drive off and then back on.  No response.  Any thoughts as to how I can get it to be recognized?

    You can try doing a SMC reset, if it doesn't work the first time it's totally OK to reset the SMC several times.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • External Hard Drive won't shut down

    New MacBook Pro 15" and Tiger my Lacie external hard drive does not turn off when the computer is shut down.
    MacBook Pro 15"   Mac OS X (10.4.9)  

    You need to provide more information about the drive. Is it bus powered or AC powered? If it's bus powered, you should probably contact LaCie support and ask them. If it's AC powered, then naturally you'd need to shut it off separtely.

  • External hard drive won't shut down after switch from OS10.5 to OS10.4.11

    i recently chanded my OS from 10.5 to 10.4.11 (as a programme i want to use is not compatible with leopard), but since i have done this my external hard-drive won't shut down automatically when i shut down my mac. i have to switch it off at the plug instead.
    can anyone suggest how i can get it to do this again?
    i'm a little concerned that i'm damaging the external drive by turning it off manually all the time..
    thanks

    Some hard drives shut off with shutdown, some don't. Sometimes hard drives that did shut off with one system will not do the same with a different system. My hard drives which did shut off, prior to 10.5 now stay on.
    This is not really a problem as all hard drives spin down after 10- 20 minutes when not in use, whether your computer is on or off. Leaving the drive on is fine, shutting it off manually is fine.

    External hard drive does not show up in imovie.

    Hi,
    Welcome to the Discussions.
    The drive's directory is damaged and as you found Disk Utility isn't equipped to repair it. You need Disk Warrior or Tech Tool Pro.

  • My external hard drive does not show up on my desktop

    My external hard drive does not show up on my dest top but, does shows in my Windows (vmware fusion) end although I can't see it ob my desktop but, I can eject it properly like any external drive. I have connected it to my windows and ejected properly (per the suggestion of someone on this forum) but, it still doesn't show on my Mac. I see the blue light and hear it running though. I have looked for it in disk utility but, still can find it. I have changed the cable and it still did not show on my Mac. I connected another external drive  and that showed up on my desktop.Any help????

    if it is NTFS then you need Paragon Software NTFS for Mac.
    NTFS volumes are suppose to be read only but in practice external drives don't always mount or work.
    If it is not NTFS then you need more details. Need more anyway.
    PS: this is not a MacBook area, it is Mac 65lbs tower related forum.

  • HT3275 Time Machine says my external hard drive does not have enough

    Time Machine says my external hard drive does not have enough space for the current backup.  It needs 34 G out of a 250G hard drive.  All that is on the drive is earlier backups.  I recently added memory, which may confuse Time Machine into thinking it is a new computer.  How can I erase old backups and complete this one?

    See #C4 in Time Machine - Troubleshooting. 
    If that doesn't clear it up, how much data is on your Mac?  If TM is only trying to back-up 34 GB, it should be able to delete old backups to do that (assuming you're running Lion).
    It sounds like your backups may be corrupted.  Try to repair them, per #A5 in Time Machine - Troubleshooting.

    If that's all you did, no.

    Just erase the drive per #1 or #2 of Using Disk Utility.

  • External Hard Drive does not show up in Finder

    My external hard drive is not showing up in Finder.
    It shows up in Disc Utility, but I do not have access to it. I have tried the following:
    command-shift c, nothing happens
    confirmed in Preferences/General that external hard drive was checked
    tried another cable
    tried another port on the back of the external drive
    tried to connect through the USB port
    re-started, etc.

    I have same problem after installing OS 10.5.8. Disk utility sees the hard drive, the computer does not. Disk utility says invalid node structure. Volume check failed. Filesystem verify or repair failed.
    That means the directory is corrupt. If you have a heavy-duty 3rd-party disk repair app, such as +Disk Warrior,+ it may be able to fix it. Otherwise, your only option is to erase and reformat the disk. They're not cheap -- Disk Warrior is about $100. And for Leopard, you need version 4.1.1 or 4.2.

  • External hard-drive does not reconnect after sleep

    Hi everyone
    I am trying to use my Energy Saver to SLEEP my iMac after 1 hour. It goes to sleep no problem, but on wake-up, my external USB hard drive does not reconnect. There is also an error message that I didn't disconnect the drive properly. I fear this may be one of Mac OS X's "features". Has anyone encountered the same thing?
    On a side note, I also find that my USB keyboard does not always reconnect as well. I use a windows USB mouse that I have connected to wake it from sleep, however my USB keyboard (the small one for Macs), sometimes does not allow me to type unless I unplug it and back in.
    Another point of note is that both the HD and the keyboard are connected to the iMac through a 7 port USB hub.

    I think this might be the issue. If the iMac is waking back up, it will likely be waking up this HUB, but the HUB might not be re-initialising the connection between OS X and the external drive or the keyboard.
    After waking the iMac, if you unplug the external drive from the HUB, then plug it back in again, does OS X pick it up again? Have you tried plugging the external drive directly into the iMac and then testing what the result is?
    If you read back on what you've said, you pointed out that you have a USB mouse that you use to wake the iMac from sleep. Is this mouse directly connected to the iMac? If so, it surely can't be a coincidence that a directly connected USB device can wake the iMac from sleep, but any USB devices connected to the iMac via a USB HUB cannot.
    I would suggest you test the drive as it is directly connected to the iMac. I would complete the same test with the keyboard too. I think you'll find it's the USB HUB.
    I hope this helps.

  • External hard drive does not show up on my desktop.

    I just got this imac and when I plug in my external hard drive it does not show up on my desktop.  On all of the macs at school it just shows up but they are running lepoard and I have lion so I don't know if this could make a difference. I have tried draging it droping it but that didn't work.
    PS I am just switching from a pc to a mac so I don't know much.

    Start a finder window.  In the menubar go to Finder > Preferences > General tab > Check show HDs on desktop.

  • External Hard drive does not show up on Disk Utility

    I have a External Hard Drive that I used to use on a PC.
    Recently, I just bought a new Macbook Pro 13'' and want to transfer my documents from the old PC to the Macbook.
    My External HD requires a password that you need to type in in order to access the files.
    This password thing runs smoothly on my PC, which I can type in my password and get the files. But when I plugged it into the Mac, it didn't recognize it. It only shows the files .exe... and other that can be run by Windows.
    So I formatted the HD (I already back up the data), and put it back to the Macbook, I still cannot open it. The system does recognize the connection but when I opened the Disk Utility while still connecting to the HD, the HD does not show on the left column of the Disk Utility.
    Then I'm stuck.
    Is there anyone here can tell me what I can/should do?
    A girl who spends hours on the internet and still cannot figure out why this sh*t is happening to her.

    A lot of external drives use firmware passwords as a protection scheme.  To use them on a mac, you need to unlock the drive on a PC (I've done it in a virutal machine before).  Once unlocked, you can format the drive for use on a mac.  The firmware won't run properly on a mac so your ability to lock the drive from the mac will be gone.  You can still lock it from a PC (I think, never tried to firmware lock a drive with a mac partition on it).

  • External hard drive does not mount after sleep

    I am using a brand new Seagate 2 TB external hard drive for my backup drive.  More often than not, when the computer goes to sleep, the icon for the drive is gone from the desktop when the computer wakes up.  I have to unplug it from the computer and reconnect it, then it mounts and works fine.  I have it plugged directly into the computer's USB port.  The drive uses USB3.  As far as I can tell, it does not exceed the power requirements of the USB port.  It is the only external hard drive I am using at the moment.
    I should note that the same thing was happening with my last hard drive.  That was a Western Digital 250 GB drive with an independant power source connected by firewire.
    I am running OS 10.6.8 on an Intel circa 2009 iMac.  My external drives worked fine for years, and it seems in the last year or so is when this started happening.
