Oh-oh. Ext FW drive shuts down my MacBook and PC when I plug it in

I have an Acomdata 250 GB ext FW HD. Suddenly, whenever I plug it into my MacBook (10.4.9), it immediately shuts down my MacBook without warning. Ditto when I plug it into the FW port on my PC (Win XP Pro SP2). When I plug it into my Digital Audio DP G4, it doesn't shut down. But no computer recognizes the drive any more. The drive seems to boot up OK, but it's not recognized. Any ideas on what's wrong? The drive holds my iTunes music, so I am pretty freaked out if the data is lost forever (yes, I backed everything up on DVDs last week).
I tried different FW cables, with the same result. Other FW drives work fine with my Macs and PC. Could the HD enclosure be bad?

You should contact the drives manufacturer. If it does it on your Mac and PC it sounds like the drive enclosure may have a short somewhere. Luckily you backed up or you may have lost everything.

    Boatmoter, welcome to the forum.
    Have you checked to see if the computer is overheating while gaming.  Games are intense and can cause heat to rise.  This can definitely cause the computer to restart unexpectedly.  There are many FREE programs that you can use to check the temps.

  • My Pavilion G4 shuts down after a few minutes when I plug it in

    My hp pavilion G4 shuts down automatically after a few minutes when I plug it in. It does not happen regularly so I'm not sure of the reason of why it happens. The laptop shuts down and when I press the power button, the light on the power button just flashes but it does not start. Even if I remove the charger and push the power button, it doesn't start. I have to remove the battery and place it again to be able make the laptop start again.

    Hi rierufied,

    I understand that you are having a problem with your g4 shutting down randomly after you turn it on. When this happens do you get an error message at all? If so, what is the error message? Does this happen both when you are on battery and when it is plugged in? What operating system are you using? What is the product number of your notebook?

  • HELP! I shut down my macbook pro and now after applications have been in full screen mode for awhile they automatically minimize and it takes me back to the desktop. How do I fix this?

    I shut down my macbook and now while applications such as safari have been open for awhile, even while active, will automatically minimize and it take me back to the desktop.  How do I fix this?

    I should add that this has happened before and I feel like it was a quick un-toggling of a box in my settings, but I can not remember what to do.

  • G5 w/New VeloRaptor  and WD 1TB drives shut down after 5 min. of inactivity

    We partitioned the VelociRaptor and got it up and running yesterday. Loaded all the programs into it and installed a new WD terabyte scratch disk that holds documents. By yesterday afternoon the computer wowed up with its extremely fast performance.
    This morning I booted up all the computers in the office prior to staff arrival. The designer found her G5 with blank screens and fans racing. We (hard) shut it down waited a bit and it rebooted instantly after startup. She went to work and the computer operated perfectly. A phone call interrupted her work, and while she was talking the screens went black and the fans started racing.
    We (hard) shut down again, waited and started it. I reset the PRAM. Everything back to normal. Again during a period of inactivity the screens blackened and the fans raced.
    How do we reset the NRAM?

    Ignore the MacKeeper ad no matter what else you decide.
    After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
    applejack AUTO
    Then let it do all 6 of it's things.
    At least it'll eliminate some questions if it doesn't fix it.
    The 6 things it does are...
    Correct any Disk problems.
    Repair Permissions.
    Clear out Cache Files.
    Repair/check several plist files.
    Dump the VM files for a fresh start.
    Trash old Log files.
    First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
    Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.
    Just sits there occupying very little space & never interfering, unless you need to invoke it in Single User Mode.

  • I shut down my macbook pro and now I started up and it started in the safe mode

    I shut down my MacBook Pro yesterday and when I started up today, it keeps starting up in safe mode, what do I need to do?

    Welcome to the Apple Support Communities
    Does your Mac start properly in safe mode? If so, try resetting the PRAM > http://support.apple.com/kb/HT1379 This will reset the "boot args", so OS X should start into safe mode. Also, you should verify that the storage of the computer is OK, so open Disk Utility, select "Macintosh HD" on the sidebar and verify the drive. If there's a problem, start in OS X Recovery (holding Command and R keys while your Mac is starting) and repair it

  • The new firefox twitter app is great - except it disappears every time I shut down the computer and I have to remove and then reinstall it every day!?? I am working on an iMac - if that is causing the problem ...? Thanks.

    The new firefox twitter app (mini tab on left of page) is great - except it disappears every time I shut down the computer and I have to remove and then reinstall it every day!?? It won't appear on the page until I do. I am working on an iMac - if that is causing the problem ...? Thanks.

    Eustace, thank you so much for writing back.  I will try what you suggested!!
    thx for your reply - apparently when I went to the Apple store a long time ago, they restore maybe photos and itunes etc from my external hard drive (passport).  I guess at that time they reinstalled an earlier operating system than my macbook came with and that somehow corrupted FileVault.  apparently there was no sparse bundle (whatever that is) for my old admin account and they said that ever since the install of the older OS that it was actually NEVER backing up anything in my admin account.
    Then, I bought Time Capsule and starting backing up to that instead.  I started having problems with it being slow etc and then StartUp Disk full errors and didn't know what to do, so I "Restored" from Time Capsule and that's when I lost everything in my Admin account and was locked out when I tried to log in - it said File Vault error ..."
    anyway - that's THAT sad story.  I was told to create a new admin account and I've basically been trying to start over - even though I have a partial save of my computer in Crash Plan and I DO see a sparse bundle listed in there, but I just don't know enough about computers to know if it's something I can get back or if I am just totally doomed. 
    I'm afraid to reinstall anything because if there is even a remote shot that the other files are still floating around in my computer, I feel like that chance will be shot forever.  I need to hire McGee from NCIS, I just KNOW he could get those files back for me!!!

  • I was editing photos in my iphotos and it says Your photo library is either in use by another application or has become unreadable on me.  I shut down my computer and when I restarted I can not access my photos, it keeps giving me

    I was editing photos in my iphotos and it froze on me.  So I shut down my computer and when I restarted I now can not access them.  It says Your photo library is either in use by another application or has become unreadable.  What can I do to fix this?

    What you're describing is the Finder window for your external hard drive.  When you're in iPhoto and try to edit a photo what happens?
    Are you saying that the photos for your iPhoto library are located on the external HD while your library is in the Pictures folder on the boot drive? That would indicate a referenced library.  You can check to see if you're running a referenced library by checking the Advanced Preference pane in iPhoto:
    Click to view full size
    So based one the Advanced preference pane in iPhoto what type of library are you running. Where is the library itself located?  It should look like this:
    By default it should be located in your Users/Home/Pictures folder. However, it could be run on an external HD.

  • How to properly shut down your Macbook?

    Hello, I have been using a Macbook Pro for nearly a year now. I would like to know what is the proper way to shut down your macbook?
    I went to iStudy for some app instalment and the sales asisstant gave me a piece of (advice?) that whenever I want to shut down my macbook, i should just snap it close after I have quit all the running applications. I don't have to press the shut down button on the keyboard or choose shut down at the apple upper menu bar cause it may damage my RAM.
    Yet, I knew this girl who just paid 2K just to fix her motherboard due to improper way of shutting down her Mac.
    So, my problem is do you have to shut your Mac down JUST by snapping it close (and of course, quit all the running applications)? Or you shut your Mac down by simply go to the Apple in the upper menu bar and choose shut down?

    Hi alswaki,
    When you close all apps and then physically close it, you are putting the Mac into Sleep mode, not shutting it down. So, it depends on what you actually want to do. When you go to the Apple menu and select Shut Down, it literally shuts off the Mac, and you have to push the on/off button to start it back up. By closing the lid, you are putting it into Sleep mode so when you open the lid again, the Mac doesn't have to be powered back on to start up again.
    Both are correct things to do. I pretty much don't shut down my Mac at all. I close my apps, and close the lid, then plug it in to recharge. When I want to use it, I open it and it "wakes up". I only restart it when I need to for an update, I pretty much never shut it down.
    But again, either way is fine to do. If you want to completely power down your Mac when you finish using it for the day, then you would select the Shut Down option. Otherwise, just close it to put it into Sleep mode when not in use.
    Cheers,

    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    See these Apple articles:
              Mac OS X Snow Leopard and malware detection
              OS X Lion- Protect your Mac from malware
              OS X Mountain Lion- Protect your Mac from malware
              About file quarantine in OS X
    If you require anti-virus protection Thomas Reed recommends using Dr.Web Light from the App Store. It's free, and since it's from the App Store, it won't destabilize the system. If you prefer one of the better known commercial products, then Thomas recommends using Sophos.(Thank you to Thomas Reed for these recommendations.) If you already use Sophos, then be aware of this if you are using Mavericks: OS X Mavericks- Sophos Anti-Virus on-access scanner versions 8.0 - 9.1 may cause unexpected restarts
    From user Joe Bailey comes this equally useful advice:
    The facts are:
    1. There is no anti-malware software that can detect 100% of the malware out there.
    2. There is no anti-malware that can detect anything targeting the Mac because there
         is no Mac malware in the wild, and therefore, no "signatures" to detect.
    3. The very best way to prevent the most attacks is for you as the user to be aware that
         the most successful malware attacks rely on very sophisticated social engineering
         techniques preying on human avarice, ****, and fear.
    4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
        your computer is intended to entice you to install their malware thinking it is a
        protection against malware.
    5. Some of the anti-malware products on the market are worse than the malware
        from which they purport to protect you.
    6. Be cautious where you go on the internet.
    7. Only download anything from sites you know are safe.
    8. Avoid links you receive in email, always be suspicious even if you get something
        you think is from a friend, but you were not expecting.
    9. If there is any question in your mind, then assume it is malware.

    == This happened ==
    Every time Firefox opened
    == a couple of months ago

    Hello Brian.
    You don't need to restart your computer to open Firefox again: you just need to close it manually through your application manager (CTRL+SHIFT+ESC in Processes tab). Anyway, hopefully this support article is what you need:
    http://support.mozilla.com/en-US/kb/Firefox+hangs
    What's probably happening is that you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
    Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
    If you want support for one of your add-ons, you'll need to contact its author.
