External Harddrives

I have 2 external harddrives that aren't seen by my Macbook Pro, OS 10.7.5, yet they are both seen and usable on my older G4 eMac, OS 10.4.11.  One of the harddrives has its own power supply and the other relies on the power supplied from the USB port.  Neither drive shows up on the Disk Utility program.  All of the thumb drives show up and work perfectly, so I don't think that its the USB port.  Any thoughts, ideas, or solutions??   Thanx for your time to reply.

Hints:
1) Do a google search on the external enclosure to see what other people are saying about it.
2) Buy a model being sold by a mac only dealer.
The oxford 911 chipset has a good reviews when used with the mac.

  • Unable to boot Windows 7 Premium from an external harddrive

    I recently gained an interest in playing microsoft based games, and just recently got my late 2013 macbook pro retina 15". I have been trying for several hours for the last two days to get bootcamp to boot Windows 7 Premium from a 500GB external harddrive without re-partiitioning my internal harddrive. I can get to the first screen of the Windows 7 Install asking about language, but neither my keyboard or mousepad respond with the windows installer. I assume this is because Windows 7 premium does not have USB 3.0 capability. Is there a workaround for this that doesn't involve partitioning my internal drive?

    That's all fine and good, but I would strongly prefer not to have to use internal drive space for Windows. Even If I were to use the internal drive to install it, I would still run into the same problems of not having a keyboard or trackpad as I've seen other users having issues with. It stands to reason that if I had a working keyboard and mouse that I would be able to install it to an external hard drive, using a workaround method found here:
    http://bleeptobleep.blogspot.fr/2013/02/mac-install-windows-7-or-8-on-external.h tml
    If I had to partition my internal drive, what would be the absolute minimum amount of space I would need?

  • Keyboard, trackpad & external harddrive suddenly stopped responding but external mouse will work?

    I have a 2007 MacBook, but the harddrive was replace begining on 2011. Ealier today mid-email my keyboard suddenly froze and my cursor dissappeared. The power button still worked so I was able to turn off my computer. When I restarted I had about 3 hours of normal functioning before the same thing happened again. The entire keyboard becomes unresponsive (including the caps lock light that does not light up) and the mouse is no longer visible. I tried connecting an external mouse and this seems to work fine, but I still can't type anything in.
    I connected my external harddrive to copy over all my files (incase this was the begining of the end). About two minutes in the light started blinking on the harddrive and i was given the message from the computer saying the harddrive was unplugged... which it was not!
    I have restarted the computer a few times, the keyboard and trackpad never come back on, the computer can no longer recongnize any external harddrive or thumbdrive but works fine with the external mouse.
    Does anyone have any idea what is going on?
    Thank you! I really appreciate your time and any advice you may have.

    Make sure it's not something as simple as the battery bulging up and exerting upward pressure on the trackpad, keyboard, and USB / FW ports.
    That's what happened to my Macbook and it showed similar symptoms.
    I simply took out the battery and let the MacBook rest for a 48 hours.  Then I ran it strictly on the power supply and it ran fine.
    At that point I bought a replacement generic battery through Amazon for about $40 including shipping and taxes.  I figured why waste money on the Apple original part if it was that very Apple original battery that went bad and bulged up like a toad? 
    MacBook has been running just fine for months now, maybe a year.

  • How to connect an external harddrive with firewire 800 to a macbook with firewire 400?

    Hello,
    I just got the external harddrive "Seagate FreeAgent GoFlex USB 3.0 1TB" with a Seagate FreeAgent GoFlex Upgrade Kabel FireWire 800. I have neither a USB 3.0, nor a Firewire 800 on my white macbook (2008). I already know, that it's possible to use USB 3.0 with an USB 2.0 port, but I would like to use it with the firewire to spare the USB port for other devices. My question: Is there an adapter or cable to use the Seagate Firewire 800 with my Firewire 400 port? I don't know, where and what to look for.
    I'm glad for any advice.

    There are many adaptors, try here

  • I moved all my music from c: drive(because it was full) to an external harddrive and now itunes can't find any of my music. Is there a way to get Itunes to find music on external drive without having to place all the music back onto the c: drive? Thanks

    Hopefully you moved the entire iTunes Media (or iTunes Music) folder to a new path on your external drive. Copy your iTunes library folder out to the root of the external drive, e.g. X:\iTunes (where X: is your external drive), then move the media folder inside it. Hold down shift as you start iTUnes and keep holding untila asked to choose or create a library. Choose the library at X:\iTunes\iTunes Library.itl. Should all be good.
    Failing that, download and run my FindTracks script and point it at the new location of your media folder.

  • HT1766 How do I back up my iphone5 to my ICloud account, when my restrictions password. My restrictions pass code has my icloud a account greyed out? Can i backup to a wd external harddrive, or try to backup to a new mini-mac, i jUst purchased?

    How do I back up my iphone5 to my ICloud account, whqen iI have forgot my restrictions password. My restrictions pass code has my icloud a account greyed out? Can i backup to a wd external harddrive, or try to backup to a new mini-mac, I just purchased yesterday? This is my first iMac and IPhone5, so i am kinda out on my own, and can use some pointers!! My phone is full of pictures, and will not download anything, until i store my pictures somewhere!!

    If you don't remember your restrictions passcode, you will have to force the phone into recovery mode and restore it using iTunes. Do NOT restore your backup. The restrictions passcode is part of the backup.
    Everything on the phone will be lost.
    You can extract the photos from the camera roll the same way you would from any other digital camera. Having a restriction passcode set should not prevent that. do that before you put the phone in recovery mode and restore it.

  • How do i copy files and folders from one external harddrive to another on the iMac?

    For some reason when i drag the folder or file that i want to transfer or copy from one external harddrive to another, nothing happens when i drop it on the destination folder or drive. however, when i drag and drop to the desktop or any location on the Imac internal hardrive it works without any issue. The only problem is that i dont want to transfer or copy stuff to the computer. i want to copy it to an external harddrive. please help if your have answers to my question.
    Thanks!

    Check the formatting of the external hard drive. To do that, right click on the drive icon and select Get Info. (Or click once on the drive and type command +i ) The pane includes information about the drive format.
    The drive should be formatted as Mac OS Extended. If it is not, run Disk Utility (App;ications / Utilities) and format the drive.

  • How do I move my iTunes library to an external harddrive?

    I recently purchased a new MacBook Pro and want to reload by CD collection into iTunes on an external drive.  In the past, I had been using iTunes for PC and the library became corrupted.  I would prefer to save the music to an external harddrive to save space on my MacBook's harddrive.  Once I load the music onto the harddrive, I want to be sure that my MacBook recognizes the library in the future.

    Creating a new library on the external drive will add to confusion because now you will have multiple iTunes libraries.  For simplicity it would be best to move your entire iTunes library to the external drive, unless you have a very good reason for wanting to split media storage locations.  To move a library if you use iTunes' default preferences settings:  Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive.  Open iTunes and immediately hold down the option (alt) key (shift on Windows) so you get a prompt to select a library, then guide it to the 'iTunes Library.itl' file in the moved iTunes folder.

  • Want to upgrade from snow leopard to lion, need to purchase an external harddrive to b/u my stuff.  will formating for snow leopard be ok when uploading to the new system (lion)?

    oh sorry, I thought that was where we put the question   I am on an extremely tight budget, but since I do shift work, I wanted to use the iCloud funciton to keep my calendars uptodate on my pc/mac mini/and iphone. Wish there were a way to do it for free on my snow and snow leopard OS, but sinc e I cannot, I am wondering about formatting the external harddrive (which I have to purchase). If I format for the snow leopard, will there be a problem re installing the information into the new snow leopard OS machine?  Also, I am wondering about the older Mac Pro I have that is the OS before snow leopard (Snow, I believe) will I be able to use this same HD for backing it up to upgrade it (at a later date)?
    Thank you for your help.
    Deb

    so sorry, I mean uploading information from the back up (ex HD) onto the new Snow Lion OS.  (and later doing the same with the Mac Pro which is the system before snow leopard.)  TY

  • How do I move my iPhoto files to an external harddrive?

    Hi there
    I only recently moved to Apple from Windows and am struggling to move my iPhoto files to an external harddrive, despite there being some quite old discussions on this on these discussion boards.
    My late 2013 32GB Macbook Pro Retina is currently at full capacity because I have imported to iPhoto all of my photos from my past few months of travel. I have recently acquired a 1TB external harddrive which I have successfully partitioned, and I have backed up my Macbook Pro's harddrive using Time Machine to one partition.
    I want to move my iPhoto library to the other partition to free up space on the local hard drive, but am needing some assistance.
    My questions are:
    1. How can I locate all of my iPhotos that I can see in iPhoto but nowhere else? I thought there would be some place I could find them and drag and drop onto the external hard drive.
    2. How do I go about moving the photos so they are only on the external hard drive? Do I have to move to the hard drive first and then delete?
    Any assistance would be appreciated.
    Thanks
    Alex

    To move your iPhoto Library to an external drive is simple and straightforward:
    Make sure the drive is formatted Mac OS Extended (Journaled)
    1. Quit iPhoto
    2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
    3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
    4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
    1. How can I locate all of my iPhotos that I can see in iPhoto but nowhere else? I thought there would be some place I could find them and drag and drop onto the external hard drive.
    The point of iPhoto is that it replaces the File Manager for everything to do with your photos.

  • Moving photos and videos from iPhone, to iPhoto, to external harddrive. Videos come out to be less than 0 seconds. HELP, PLEASE!

    Hi guys! This is my first discussion and I'm not exactly sure what kind of details to put, so I'll just be as detailed as possible. I hope I don't confuse anyone. I really REALLY need help!
    I've got a 16 GB iPhone 4S and always find myself filling up my phone with photos and videos, so I upload both onto my MacBook Pro 2011. Now that my laptop's getting full... I'm uploading all of those backed up photos and videos onto a 500 GB Seagate external harddrive.
    All of my photos open just fine. It's the videos that I'm worried about. All of the videos that I've loaded from last year (2013) are playing well. Anything before 2013 aren't opening properly. I'm opening the video files directly from my external harddrive. It goes:
         1) Opens up QuickTime Player
         2) Shows that it's converting
         3) Shows a frame from the video, but the time says 0:00-0:00.
    I had a LOT of videos from before 2013 and would like to retrieve them if possible. They're no longer on my laptop though. All of the video files are 20 KB - 980 KB and has to convert on quicktime player for me to watch them. Some of the video files I've tried out were from 2013 and 24 KB and opened just fine. I've opened both ~20KB - ~900 KB video files before 2013 and they're all 0:00-0:00 time length. Anyone else having this problem? Thanks!

    I have the same issue.  We've lost all of our older videos including videos of our children and since passed family dog.  I have no idea why this has happened.  I have backed up religiously, but now even the archived photos are 0 seconds.  So frustrated with iPhoto.  This is the second time this awful software mysteriously lost pictures or videos.  Last time it was the birth pictures of my second daughter.  And now this.  Horrible horrible product. 
    Older videos are all now just 0:00:00 in length.  We did not alter these at all!!
    HELP!!

  • If Adobe has disabled the ability to use Lightroom 5.7 to view the images in the external harddrive, how does one view the images in the file on the external drive without bringing them back to the Lightroom Library?

    Jpeg images dragged over from Photoshop are veiwable as thumbnails on the external harddrive.  However images brought over as RAW of DNG are not viewable.  Is there anyway to view these type images on the external harddrive?  It would be nice to have a glimpse of what you are bringing into Lightroom by just looking on the external harddrive as you can with the jpegs.

    From the Library simply click the import button and navigate to your folder on the ehd. Choose the folder and click Add at the top of the dialog. You should see thumbnail previews in the import dialog where you can select what to import.

    Apple has really crappy NTFS read-only that does not always work. And it is probably a licensing issue.
    Paragon Software is constantly being updated and supported with their NTFS for Mac OS X - they also have an HFS+ driver for Windows that works - Apple's HFS+ read-only driver for Boot Camp / Windows does not.
    I keep seeing problems and lack of support for MacFUSE, that could change.

  • External harddrive in network not recognized by windows XP

  • Unable to sync my ipod-library moved to external harddrive

    Please Help
    I have moved my library to an external harddrive, and had no problems for quite a while, but now i cannot sync my pod.
    It is saying that the original file cannot be found. I have made sure that itunes is looking in the right place, and can make it find them manually (when it asks if I wish to locate it, I can go straight to the correct file), but with over 2500 tunes, this is going to take forever. Any one have any thoughts on how this can be rectified?
    I have tried consolidating the library as suggested elsewhere in this forum, but to no avail. HELP!

    You get exclamation marks or dead tracks because iTunes can’t find the file. This can happen for a number of reasons:
    The song file or a folder in its path was renamed
    The song file or the folder it is in has been moved
    The song file has been deleted
    The device containing the song files e.g. external drive is not accessible.
    The most likely thing is that the external drive letter has changed, but that is just a guess. If it has, can you change it back?
    If that's not it can you confirm your configuration.
    Is you iTunes folder containing the library files located on your c: drive with just the music on the external drive.
    If you go to Edit>>Preferences>>advanced, what is the setting for your iTunes Music folder?
    What letter is allocated to your external drive and what is the name of the folder containing the music.
    If you don't know about changing drive letters, this article about somthing else contains instructions:

  • The volume for "*.jpg" cannot be found. External harddrive.

    I have recently purchased a MacBook Air and have moved my iPhoto library to an external harddrive. Recently, my all of my older photos and videos when clicked on come with the error "The volume for "*.jpg" cannot be found." However, my new imported photos do not have this problem. When I click "Find Photo" and select that photo on my harddrive, it still gives me the same error.
    I have many photo albums and would rather not import them all again just to re-organize them. Do I have any other alternatives?

    Are you running a Managed or a Referenced Library?
    A +Managed library+, is the default setting, and iPhoto copies files into the iPhoto Library when Importing
    A +Referenced Library+ is when iPhoto is NOT copying the files into the iPhoto Library when importing because you made a change at iPhoto -> Preferences -> Advanced. In this scenario you are responsible for the File Management.
    Regards
