External Hard Drive mounts, but can't be selected or opened

I have a 1 TB Western Digital external hard drive. When I plug it into the Firewire 800 port of my 13" Unibody MacBook Pro (running Snow Leopard), the drive shows up on my desktop and in Finder windows, but when I try to access the drive, or "select" it, I get the message "The alias "[name of drive]" can't be opened because the original item can't be found". If I select the fix it option, it gives me a finder window to identify the item to which I want it to refer (the hard drive), but when I select the hard drive in this window I get the same message. I've used Disk Utility to verify the disk and it says that it is fine. Also, I have two other external drives, a smaller WD drive and a smaller Seagate, and they both mount and are accessible. Any thoughts?

having the same issue with a mounting a hard drive that drovers is. any solutions? funny thing as that the drive will mount on a G5 running 10.5.8. have spent several hours on the phone with apple help to no avail. final suggestion was to wipe drive and reformat. cant't do this as I do not have enough space to back-up to. Would appreciate any suggestions.

I want to put all my music onto an external hard drive. But I can't get it to put music on my itunes. The music list is completely empty and so is my IPOD.

You say the music is not on the external HD, the music list (iTunes?) is empty, and it is not on the iPOd. Then where is the music you want to move to the external HD?

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.

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,

I'm not sure if my iPhoto library is being backed up by Time Machine. I am backing up to a LaCie external hard drive. I can open photos that are in folders but not those that are in iPhoto.

Do a restore from Time Machine. That will tell you.

They can provided you remove them from the Exclude list. Normally, Time Machine does not automatically backup external drives.

How do I point iMovie to events in my external hard drive so I can play projects which use them?
MacBook, iMovie 9.0.4

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)

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!!

After installing Mountain Lion doesn't external hard drives mount or stay mounted. Anybody else with this major problem?

After installing Mountain Lion doesn't external hard drives mount or stay mounted.
I have tried resetting my Mac's PRAM but the problem still remains.
Even USB memory sticks are unmounted efter a few seconds.
Anybody else with this major problem?

I have the same problem, although mine has not been solved by ESET update, finder settings, PRAM & SMC resets or anything else.
Don't get it, my external hard drive still works on both my housemates computers - one macbook pro (with snow leopard) and one dell, just not on mine with mountain lion.
Any ideas for me guys?

What is the best priced External Hard Drive, that I can reboot from, for the MacBook Pro?

I have a MacBook Pro with 10.9.4. I am looking for a 3T External Hard Drive that I can boot from if my system goes south, that I can afford. Any recommendations?
Mike

Don't know the best priced, but the external drives I like best are the OWC, http://www.macsales.com Mercury Elite Pro quad-interface drives. I have four of the 2 TB drives for my MacBook Pro and iMac and they are terrific. OWC is a Mac specialist supplier with the best guarantees and service you will find.

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.

Thanks!

I called Apple Support and they walked me through it. They told me to basically copy and paste my music to the external hard drive. (I think.) Or maybe it was they had me transfer a folder to the EHD. I don't exactally remember it was a few years back. But I tried to plug in the EHD before starting and...nothing. Still says same thing, "locate file."

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.

How do I export itunes library onto an external hard drive so i can put the music on my new mac book?

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.
