External Hard Drive support Trash can?

Is an external USB hard drive supposed to support the Trash can in Lion?  I have my Lightroom database on an external hard drive and when I delete a file, it says the Trash can is not supported. 

I've been having the same problem, to get it to work create a new folder on the external drive, then trash it. After this Lightroom starts to use the trash can again. However I do need to repeat this after a reboot/empty trash(not sure which one it is)

  • How can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

    Hello everyone, how can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

    OK. Start with:
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to two (2). Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
    4. Click on the Erase tab in DU's main window. Select one of the two partitions, preferably the first one, change the Format type: to MSDOS then click on the Erase button.

  • Does the time capsule work as an external hard drive that you can access from multiple lapttops

    I have a mac desktop, a macbook and a pc laptop. I also purchased the time capsule. Will that functional as an external hard drive that I can use to save a share documents between. Trying to figure out the best way to work on documents between devices. new to max and trying to make the full switch but still working with toshiba laptop for a while too.
    Any help is appreciated.

    Hello jhettenhausen,
         Yes, it can function as an external drive for all the devices.  As for Windows, you just need to make sure that
    it is Windows Professional or XP, as they support mapped network drives.  Windows 7 Home Premium doesn't is not capable of mapping network drives.  At home, I have a ubuntu laptop, Windows 7 Profesional laptop, and Macbook Pro and they all backup to the Time Capsule 1 TB.  Hope this helps!!

    iTunes: How to move your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
    do not confuse moving your whole folder and library with moving just media files as in
    iTunes for Mac: Moving your iTunes Media folder - http://support.apple.com/kb/HT1449
    Quick answer if you let iTunes manage your music:  Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive.  Start iTunes with the option key held down and guide it to the new location of the library.

    Welcome to Apple Support Communities
    Connect the external drive and open a Finder window pressing the Finder icon in Dock. Then, drag the folder to Finder, so it will be copied to this external disk.
    If you can't copy this folder, probably you have to format the external disk or use an app that allows you to write in that external drive. Mac OS X can't write in NTFS external disks

  • I have been using my newly purchased Iphone for Iphonagraphy (Iphone photography).  I would like to sync my Iphone to my external hard drive so I can move photos in and out of my Iphone, to make use of the apps I have exclusively on my phone.

    I want to sync my Iphone with the external hard drive so I can move photos from my phone to the hard drive AND BACK!  I'm using a Windows OS

    You have several options:
    Connect the phone using a cable to your computer. Use the camera and scanner wizard to import the photos from the Camera Roll, then organize them and sync them back to the Photos app (see: http://support.apple.com/kb/HT4083). the Camera Roll is intended for temporary storage only.
    Save the images to your Dropbox account. It's free, http://www.dropbox.com. There's a Dropbox app for the iPhone, and also for Windows, Mac and Linux. Dropbox can also be accessed using a web browser. Dropbox (and similar services) provide cloud-based storage that can be accessed from anywhere.
    Use Photo Stream
    Email or text (MMS) the images to yourself
    Create a Picasa or Shutterfly account, save the images to it, then download to your computer
    I'm sure there are others.

    How do I point iMovie to events in my external  hard drive so I can play projects which use them?

    Hi
    You can do this - by not doing it the way You describe as it will not work.
    a. the external hard disk - MUST BE - Mac OS extended (hfs) formatted -
    UNIX/DOS/FAT32/Mac OS Exchange - will work for most things - BUT NOT FOR VIDEO (iMovie, iDVD or FinalCut doesn't matter)
    b. Do not alter or move any folder named
    • iMovie Event's - or -
    • iMovie Project's
    on DeskTop/Finder - at all
    All moving's of Events and Projects must be done within the iMovie Application - then connections will not break.
    (move them back and see if iMovie remembers them - then do move as described above)

    This article has a link for more information on finding your profile directory: [[Fix the "Could not initialize the application's security component" error message]]. On Windows 7, you can try this (either in a Windows Explorer window address bar or from the start menu search box):
    %APPDATA%\Mozilla\Firefox\Profiles
    You may see one folder in there and that's the one you want. If you see more than one, look for the one with the most recently modified files.

  • I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

    First, you cannot do this if you have a Boot Camp partition.
    Second: Create a new partition.
    1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
    2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)
    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
    You should now have a new volume on the drive.
    It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss.  Your drive must have sufficient contiguous free space for this process to work.
    Third: Install Snow Leopard.
    Boot from your Snow Leopard DVD. Follow instructions for installation being sure that before you actually install Snow Leopard you have selected the new partition as your target destination.
    Booting From An OS X Installer Disc
      1. Insert OS X Installer Disc into the optical drive.
      2. Restart the computer.
      3. Immediately after the chime press and hold down the "C" key.
      4. Release the key when the spinning gear below the dark gray Apple logo
          appears.
      5. Wait for installer to finish loading.

    If time machine puts all of my photos onto my external hard drive using time machine, can I then delete the photos from my computer but view them again from the external hard drive? Basically, can I free up space on my mac but not lose years of photos?

    To add to Niel's comment bear in mind that if you have a backup copy on an external HD and later delete the orignals on your Mac HD you will then only have one copy - so no backup.
    If the pictures are precious you should have at least two copies, and ideally another copy kept off site,

  • Have over 86GB of music now showing as "other" and although it is still on my iPod it is not playable.  Most is from imported CDs. I do have a backup file on an external hard drive. How can I fix this?

    Have over 86GB of music now showing as "other" and although it is still on my iPod it is not playable.  Most is from imported CDs. I do have a backup file on an external hard drive. How can I fix this?

    To import music into your iTunes library on the computer go to iTunes>Help>iTunes Help>Add items to iTunes and follow the instructions
    Delete the "songs" that do not play in your iTunes library and reimport them.

  • Moving iTunes Library to external hard drive when iTunes can't consolidate.

    Hi guys, hope you can help.
    I want to move my whole iTunes library to an external hard drive and then delete it all from my laptop, and from reading around I realise I have to consolidate the library into the iTunes music folder. However, as my internal hard drive on my laptop is completely full, iTunes won't let me do this, saying I don't have enough space. Is getting the libary into the iTunes music folder the only way of getting it onto the external hard drive?
    I can't really free up much space on the laptop as most of it (45 out of 60Gb) is the music I want to transfer!
    Thanks very much!

    Over half of my stuff isn't there.
    Isn't where? In iTunes or not in the iTunes folder?\>Is it possible to copy the iTunes music folder from my laptop to the external, and consolidate from iTunes directly onto there?
    Why not do as I posted above? Point iTunes prefs Advanced to the external then consolidate. Everything will be consolidated to the external.
    You can then delete \Music\iTunes\Media\ folder and hunt around the internal and delete all the other songs that were not in the iTunes folder.

  • I purchased a MyBook Studio 4gb external hard drive.  I can't get it to work properly.  WD have assessed it and say its fine and that the problem is with Apple?

    Hello EucaBlue!
    So in Disk Utility, with the external harddrive selected, go to the Partition tab, and then under "Partition Layout:" select 1 Partition.
    After than, verify that it is formatting the drive as "Mac OS Extended (Journaled) under "Partition Information"
    Also verify that it's using using the GUID Partition Map under the Options button at the lower left of this window.
    Then click apply and confirm that you want to format the drive. It will ask you if you're sure, and probably for an Administrator password.
    Once your harddrive is formatted properly, you should be able to use Time Machine, or any other Mac backup software.
    Happy tinkering!

    Macs can't write to, nor create folders on, NTFS formatted drives without the use of third-party software.
    If you want to maintain the NTFS formatting, try Paragon's NTFS for Mac -> http://www.paragon-software.com/home/ntfs-mac/.
    Good luck,
