1 source file on external drive - but duplicates of files in iTunes - help!

I recently moved all my music to an external HD and followed mac's intructions for the transfer w/o any probs. However, the HD died (dropped it) and everything was lost on the HD.
To solve this, I used a program called "Pod to Mac" in an effort to recover all my files (about 35 GB) from my iPod. Worked very well. All files are now back on a new external HD.
The issue I've encountered is that in iTunes, I now have two versions of each song. Both versions in iTunes refer to a single source file in my external HD ... so if I delete one file in iTunes, I delete the source file for the second copy of this file in iTunes, too.
This isn't a big problem, except iTunes now thinks that I have 70 GB worth of music (ie, 2 times 35 GB; even though I really only have 35 GB of music), which means I don't have enough memory in my iPod to sync all 70 GB.
How can I delete one version of the file in iTunes w/o messing with the source file on my external HD?
thanks.

You'll have to try to repair the drive on a PC.
How is it possible that iTunes can read the files?
Some things will still be readable when corruption occurs, the big problem is when writing occurs when there's corruption.

Keeping music files on external drive, but import onto library?

I am a new mac user, and I used to have iTunes on a PC with all my music files saved onto an external hard-drive, but now since i got my Mac I want to be able to view and play my music on my iTunes while keeping the files on the external so as not to take up all my hard drive space. How would I go about telling iTunes to read the files from an exteral source?
Thanks!!

File > Add Folder to Library.
But first, go to Edit > Preferences > Advanced > General and make sure that "Copy Files to iTunes folder..." is NOT checked.

Itunes accesses files on external drive but not showing in finder

I'm running OS 10.6.8. I have an external NTFS drive that I read and wirte to using NTFS mounter. I have files that iTunes show are in a folder on the external drive. iTunes will even play the songs. When I navigate to that folder in Finder there are no files displayed. I connected the drive to a PC and navigated to the folder. Windows says the file (folder) is corrupt. How is it possible that iTunes can read the files? How can I get read & write access to my files?

Music stored on external drive but doesnt appear on new computer

I store my music on an external drive and in a folder E:\ Hugo's Tunes because my laptop drive is too small. Recently laptop died and I have installed itunes on another laptop also with a small drive. I cannot see my content on the new itunes. I have set location in preferences to E:\Hugo's Tunes without any benefit. Clearly I'm doing something silly but don't know what. Help please

Hi Hugo. If the content was stored on the external drive but the library files were stored on the internal then you have lost all your original library information such as date added, ratings and play counts. Having pointed iTunes to the external drive already you still need to import the content into your new empty library. If, on the other hand, you had successfully put your library files on the external then you need to hold down shift when starting iTunes and browse to the library on the external drive.
Assuming my first guess was correct I'd actually recommend that you use the hold-down-shift-when-starting-iTunes method to create a new empty library at <External>iTunes, then move the existing media files into *<External>\iTunes\iTunes Media* and finally import *<External>\iTunes\iTunes Media* into the library. This will make moving the library between machines much easier in future.

Putting some music files on an external drive, but keeping only one library

I know how to keep two libraries, one on an external drive, and one on my HD...but I'd like to know how to do this:
move some of my music files off of my HD and to my external drive, but maintain the same library (and only one) on my HD. So...when iTunes opens, I see all of the music files in the database, and if I choose a song that physically resides on the HD, it plays it from there, and if I choose one that physically resides on the external drive, it plays it from there. I want to free up space on my HD, but I don't want to have to keep two separate libraries.
Any help is appreciated!

It's easy. After you split the music you can add the music from the different locations to the library and it will play them from wherever they're at. The important thing to do is to go into *System Preferences* in iTunes Advanced and uncheck the *Copy files to iTunes Music folder when adding to library* or iTunes will put duplicates in what ever iTunes Music folder you have iTunes pointed at. This folder is only important when you are adding content that you do want copied to the Library, such as from a CD.
I use this for my iTunes music and movies that is stored three different drives. One is a network drive.

Moved files from external drive to internal, now can't delete duplicates

I had my music on an external drive, but then I got a new Mac with plenty of space and I copied the files onto the internal hard disk. Now two copies of every song show up, which is annoying. How do I remove all the old ones? There are thousands I cannot do it one at a time... I don't see any way to sort on the field that shows the exclamation point, so I could select them all together.

Can see but not save/modify files on external drive

New Mac user. I have an external drive for all photos/movies that I've used wth a PC.
Bought the Mac. I can pull files from the drive but I can't access the drive to delete/modify existing files or save new files.
It's treats whole drive as "read only".
How can I modify stuff on the external drive and save new files to the external drive?
thanks.

You can't withdraw the question/thread only close it by marking it as solved.
NTFS was the "problem", right ?

I recently purchased a new iMac with an external drive. I want to transfer my files from my old iMac to the external drive, but I'm afraid that doing that will compromise the use of the external drive on my new iMac. Comments? Help?

I recently purchased a new iMac with an 1 Terrabyte external drive. I want to transfer my files from my old iMac to the external drive, but I'm afraid that doing that will compromise the use of the external drive on my new iMac. I have not downloaded the external drive's software onto my old Mac because of this concern. May I simply "drag and drop" the contents I want transferred to the external drive, then set up my new Mac with the drive and download there? or is there a better procedure? Comments? Help?

If your intention is to copy a just documents and data (word processing files and music for example) then yes, you can use drag and drop. If you want to transfer data and applications and permissions, it would actually be easiest to connect the drive to your old computer and turn on TimeMachine. Once TM is finished, connect the drive to your new computer and restart it holding the option key to get into Recovery mode. Then you can use the restore from TM option to transfer your data and programs to the new computer.

Cannot reinstate catalog after returning PC (Windows 7) to factory settings (because of worm infection). Catalog was backed up on external drive but not using PSE backup facility. Cannot find and *.tly file. Is this hopeless?

If you made backups of all of your photos and your catalog file using some third-party method (i.e. not using the PSE catalog backup command), then you should be able to restore everything.
Step 1. Put the photos in the EXACT SAME LOCATION as before. For example, if they were in subfolders of C:\Users\<username>\Documents, then they must go into the exact same subfolders of C:\Users\<username>\Documents.
Step 2. Move the catalog file to wherever you want it to be, and then double-click on it.

I have been backing up iMovie 08 files to my external drive, but for some reason I can't open these files in iMovie. I used drag and drop to copy them.

You really should be doing backups with an actual backup application, especially one that will work automatically, and, if your external HD is large enough, back up your entire system. These can automatically back up only what's changed since the previous backup, and some will keep "archive" copies of things you've changed or deleted, also.
Too many things can go wrong, such as your internal HD failing, and you'll have a major project to reinstall everything.
You already have Time Machine, built-in to OSX. You might want to review the Time Machine Tutorial, and perhaps browse Time Machine - Frequently Asked Questions.
#27 in the second link mentions some alternatives, too.

How to store iMovie files on external drive?

I'd like to store large video files on an external drive, but iMovie seems to automatically import everything onto my internal hard drive.
1) Can I set it to automatically import to an eternal drive?
2) If not, which files can I safely move to an external to free up space on the internal drive?
3) Should I move the raw files to an external before I edit them, or after?
4) In any case, my general question is how to conserve space on my internal drive by using an external drive for iMovie files?

Get an external drive and make sure it is formatted as HFS+ (journalled) or MacOS Extended (journaled) (two ways of saying the same thing. If the external drive is formatted as FAT32, iMovie will not recognize it.
You can reformat if necessary using the Disk Utility.
When you import from your videcamera, you can select your External Drive as the target of the import.
If you have Event Files that are already on your internal drive, you can move them to the external drive, but you must do this from within iMovie. If you move the events using the Finder, your projects that link to these events will be broken.
To move the Events from within iMovie, select VIEW/EVENTS BY VOLUME.
In your Events Source Pane, you should see all your Events and also an icon for your external drive. Drag an Event icon to the hard drive icon, and it will move the Event to the hard drive, and automatically place it into the proper folder on the external drive so that iMovie can recognize it.
Leave Projects on your internal drive. If you upgrade to iMovie 09, it allows projects to be on the external drive, too. Project files are generally pretty small, though. Your video footage is in the events.

Merging Files From External Drive To Internal Drive

Here is the deal. I have a notebook (Windows) with two internal drivers (C&D) and two external drives (G&H). Currently the iTunes program is located on my C drive with the other iTunes folder under "My Music" on the C drive. I have all of my music on the G drive and all of my movies and TV shows on the H drive.
What I want to do is somehow get all of my music, movies & TV shows onto my D drive so that my content is with me when I am away from home. I am going to scrap the external drives.
I know I can just copy the files over from the external drives to the interal drive and re-add them to iTunes but I really don't want to lose my album/movie art.
I am not sure how the "consolidate library" option works. If you have any advice I would be appreciative.
Sorry if I am beating an old horse but I tried searching the forums and could find an answer for my circumstance.

How do I keep iTunes from indexing files on external drive?

Hi,
I did a clean install of Vista from XP. I used Windows Easy Transfer to restore my As part of the upgrade, I did a fresh install of iTunes 8. I think I was running 7 before but this may not be significant, and I may be mistaken.
iTunes automatically (?) indexed all MP3 and m4a files both on my C: drive and on my external drive. These files are largely duplicates; I only want my music on C: to be indexed by iTunes. I've searched and searched here, Help and with Google, have found some very good information about moving files to another drive, but haven't managed to find a way to limit the drive that iTunes looks at. (I have 3 external drives but only the one has music files on it.) Any help would be greatly appreciated.

Yes, but I don't use the default.
iTunes does not move files from their original location. It copies them to the iTunes music folder when they are added to the library.
I'm pretty sure mine does not copy them; it creates pointers to them in their original locations. I believe this is an available option to the default.
If they are not showing up in iTunes and they are not in the iTunes music folder shown in iTunes prefs -> Advanced - iTunes music folder location, then you are good to go.
Then I'm good to go. I've got 2800 tracks in my iTunes music folder, plus another 6000 elsewhere on my C: drive, all of which are correctly listed in iTunes. (There also a bunch of WMAs which, for these purposes, don't exist). None of the ones from my J: drive are listed in iTunes and none have been copied to the iTunes music folder. Thanks again for your help.

Music on external drive but want to use itunes when drive is not connected. How?

I used to be able to do this, but can't remember how it was set up. I have my music on an external drive, but I don't want to have to plug it in everytime I want to access iTunes to use the store or look for apps.

I have already turned on iCloud Photo Library and it works just fine for my iPhone. BUT, what I want is for it work on my main machine, the macBook Air. I do NOT have an iMac or other to store the "system" Photos library. I do Not have room on my internal drive for the macBook Air ("system" library is located on an external drive). I don't want to have to lug that 3 TB drive with me. It also will not let me move the library file. The library file is close to 40 Gbytes and I have less than 20 left on my internal drive (and I don't dare let it get much smaller than this)....
Any ideas as to how to do this?
For my iTunes library, I ran into a similar issue, but I simply started a new library and dragged the files (on my external drive) into iTunes. This told iTunes where they were without copying them to the internal drive.
I would think something similar should work with Photos, but I don't know how to do it.

The memory on my MAC is full. It holds 4GB of RAM of which 79GB are photos. I would like to back up my photos to an external drive but just do not know how. I do not wish to use time machine. How do I back up my photo library, then delete them from my MAC to free up that 79GB? Thank you.

Hi
Just to clarify a couple of points in your post.
RAM (memory) is different from hard drive space. You have 4GB of RAM, but that has no bearing on the amount of drive space you have, of which we know that 79GB are photos.
If those photos are in iPhoto, you should be able to move the entire iPhoto Library, from the Pictures folder, to your external hard drive. You can just drag and drop. Do not have iPhoto open while you're doing this. Once it's done, you can double-click on the moved iPhoto Library file to associate it with iPhoto, so that the app remembers where the library is for next time.
One more thing. When you move a file to a different location, and then delete the original, you don't have a backup. You still only have one copy. So if that external drive dies, you will lose all your photos. Time Machine is a very good way to prevent this from happening. You should dedicate a different drive for Time Machine backups.
