ITunes 7.6 running slow with library on external drive

Ever since upgrading to version 7.6, iTunes freezes for about 30 seconds to a minute, every 2 minutes or so. Essentially, half the time i'm using it, I'm waiting for the "pinwheel of death" to stop spinning. My library resides on an external drive, when I open iTunes without having the drive connected, it doesn't freeze at all. Also, I noticed that when this freezing occurs, the light on my other external drive, and even my 4GB USB-key drive flash repeatedly, as if iTunes is searching for something.
I work for a music company and this is occuring on our two other Mac's as well: one is an iMac G5, and the other a duel-processor PowerMac G5. The iMac G5 actually has it the worst: when first opening iTunes, it is unusable for about 20 - 30 minutes while it seems to be scanning the external drive.
This did not happen with version 7.5.
I tried deleting iTunes preferences and reinstalling 7.6. I'm hesitant to roll-back to 7.5 as we have a ton of information in the library that I'm afraid to lose. But, if no other solution is available, that's what I might have to do.

Two suggestions:
1- Have you looked at this announcement? http://discussions.apple.com/ann.jspa?annID=552
2- Are you certain it's not the external drive? If it is happening every time you plug the external drive into another computer (you mentioned an iMac and a PowerMac), then my inclination is to think the problem is with the external drive, and perhaps not iTunes. If the light is flashing on the HD, that doesn't necessarily mean that iTunes is searching for something; it means your HD is trying to complete a process.

Using itunes 9 on local drive with library on external drive

Hi,
My current library is too large to fit on my local HDD, so after preforming a needed reformat,I decided to move my backed up media (mp3's, ipas...) to my external drive.
When I installed itunes, I changed "itunes media folder location" to the external drive (D:\itunes). I then consolidated the library.
The problem is this as follow:
When I drag an app ipa from my external hard drive (E:) to itunes it backs up the ipa to another external drive folder (D:\iTunes\Mobile Applications) which I specified (which is what I want it to do).
BUT, it also copies the ipa to the ORIGINAL "C:\Users\Name\Music\iTunes\iTunes Media\Mobile Applications" disk location!
I don't want itunes to copy the ipas from E: to both the original "C:\Users\Name\Music\iTunes\iTunes Media\Mobile Applications" location and "D:\iTunes\Mobile Applications". I only want a copy of ipa at D:\iTunes\Mobile Applications, not the original location.
Please help, itunes is really ***** me off.

I've been living the exact same nightmare. Spoke with applecare tech who was unable to help me, got transfered from hardware to software tech, eventually a supervisor acknowledged that he had no idea what was happening and his recommendation, "best I can suggest is that you try google it". Disappointing to say the least, I mean really if 'free' google supersedes the 'paytoplay' applecare, they have a business model issue. (Apple Expert Case 144795352).
I am currently resolving to leave the mobile applications on the HDD, while all the other iTunes media lives on my external drive... If I learn anything more, I'll post it here.

Linking itunes on new computer with library on external drive

I have just purchased a new PC and want to run Itunes on it. I had moved my library to an external hard drive which I want to use with the new computer. I have downloaded iTunes to the new computer but I don't know how to get it to find the library on the external drive. Is this an easy procedure even for someone with limited computer skills?

Thanks for responding Chris. I followed the instructions from Apple and moved the music files over to the external drive. I'm not sure what that left of itunes on the old computer. Now I've downloaded itunes to the new computer and even though the external drive is connected itunes library is empty. I can see that all the music files are actually on the external drive, I just don't know how to get the two linked. I'd like to keep all the music on the external drive to conserve space.

Synching with library on external drive

I had my ipod running well with all files on an external hard drive. I just had to install a new internal hard drive and I am having the following problems. 1st, when I plu in the ipod I get a message saying that I am synched to another itunes library and I can only be synched to one. 2nd, I can't get itunes to recognize the library on my external drive. So, how do I get the ipod to recognize my library and synch with it? Thanks in advance for your help.

The symptoms you describe correspond to the situation where you have your media on the external drive but the iTunes database (where playlists, ratings, etc. are stored) on the C: drive. If you can access the old drive, look for the C:\Users\username\Music\iTunes folder, and in particular for the iTunes Library.itl file. Then see turingtest2's user tip on Make a split library portable for steps necessary to bring your library into a standardized layout - I'd suggest that you aim to have the complete library on the external drive, in this structure:
where you primarily make use of iTunes' consolidation functions to move files and folders into this structure. Once everything's in place, get a second external drive and use this to create and maintain a backup of your library (much easier with this "well formed" layout since everything you need to backup is in a common folder).

Local preview database with library on external drive

I'm wondering if iPhoto '09 has made any progress with the handling of photo libraries on external media and drives. With so many large photos it is impossible to store my entire photo archive on my laptop, but I'd like to have access to small preview images, while storing the originals on an external drive. To this date there is no option that I'm aware of to move some photos to the external drive, but still have access to the previews when the external is not connected. Adobe lightroom does this and so do other photo managers. This is really the one thing keeping me from using iPhoto and I think it's a horrible oversight. Has this been fixed or improved in iPhoto 09?

You're referring to a referenced library and even though it's possible the risks, IMO, greatly outweigh the advantages. Since you have a laptop and want to have at least some of the pictures to take with you on the road I suggest two libraries: a full library to be run off the external HD and a smaller one with the most current or needed photos.
You can use iPhoto Library Manager to copy Events or Albums between libraries and keep the metadata intact (titles, keywords and descriptions - Faces and Places are not yet supported but should be soon).
There are some apps that can create a catalog of thumbnails for viewing with the originals not available. QPict is one that can do what you want. More on the professional side isMedia Expression. It can do that as well as much, much more. I use it as my primary DAM (digital asset management) application and iPhoto for creating books, calendars, etc.

New PC with library on external drive--no playlists or ratings?

My previous Win8.1 PC finally died after six years (power supply, I suspect, but it could have been more)--so I picked up a new 8.1 Dell. I had previous been using an external drive as the library for iTunes. Upon firing up iTunes, it did recognize the drive and added the music automatically. Curiously, I had to manually add books, podcasts, and movies. However, all my playlists and song ratings are gone. I could theoretically extract the C drive from my old PC, but I'm wondering if there's some other way to retrieve them. Any ideas? Thanks...

ITunes + Ping extremely slow with Library on external HD

Hi,
My Library is on an external HD connected to an Airport Extreme base station. My MacBook is connected wired to Airport, so there are no possible wifi connection issues.
iTunes is extremely slow since version 10. If I select a song and want to select another one, I've got a spinning beach ball for at least 20s. Change a rating: 20s delay. Every move I make: at least 20s delay...
My guess: every time I select a song, iTunes connects to Ping to fill up the dropdown menu next to the song title. Disabling Ping doesn't help. I tried in Terminal "defaults write com.apple.iTunes hide-ping-dropdown -bool TRUE", but this merely hides the dropdown menu, it doesn't stop the functionality.
iTunes is basically not usable anymore.
Any suggestions?

You cannot.

How to transfer iTunes to new mac while keeping library on external drive?

I have a new iMac (running 10.4.11). Old mac is a G4 powerbook, which is synched to my ipods and iphone. My iTunes library is on an external hard drive. How do I get the new computer to "own" the iTunes account and media library so it will synch with my devices and not tell me I don't own the music? Thanks!

Have a look here (click the text after this arrow -> iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod
I don't understand what you're suggesting at all.
I'm suggesting you change your signature line to reflect your current computer and current OS so people know what to help with.
Change what under "my settings"
Your computer model and your OS version. You list two different computers and 2 different OS versions.
and and where is "my settings"?
As stated above, it is here -> My Settings or at the top right side of this window.

Photoshop CS6 keeps crashing. I am using a brand new IMAC, I have 16GB RAM recently updated as it was running slow with 8GB and lots of hardrive space. When it crashes, i lose all my presents and it changes my preferences, it also fails to save or produce a recovered file despite settings asking it to do so every 5 mins now. When i try to report the problem, it says it has found an issue and gives me a link to a solution....but wont let me click on the link.... PLEASE HELP! It's killing my productivity.

If the crash started right after you added RAM, it could be a bad Ram dimm. You can try this - change the amount of RAM in Photoshop to 4G, this should stop Photoshop from using the higher ram. If it doesn't crash, it's probably the ram. Or run a diagnostic app. You don't say when it crashes, what you're doing when it crashes - it there a pattern? Did it ever work on this computer? Did it work on your previous computer? Without a lot of data, it could be related to the new computer... What OS version? Did you recently update it? Have you updated Photoshop to the most recent update?
Do you have any plug-ins loaded? Try restarting Photoshop, and immediately press & hold the shfit key to turn off plug-ins.

My Macbook Air is running slow with Yosemite.

My Macbook Air is running slow with Yosemite.
I checked out most of the blogs and everything and have removed widgets from the notification center, but everything seems to run kinda slowly.
Sure, i have the base model 2014 macbook air but that 4 gb ram should run a freakin finder just fine. I had Mavericks installed before, and with that, i could do everything. I even made cool music in GarageBand and nothing was lagging for me. Now i installed Yosemite... Everything is lagging. Scrolling seems like it happens around 10 FPS. That aint good man. Memory cleaner says around 1gb ram free when only the finder is running in the background (before it did around 2). I just uninstalled Memory Cleaner o I'm not looking at that little amount of memory. I don't know what to do now? I would appreciate it, if someone would help me. Otherwise, ill just wait for a new update.

Since it's new I would take it back for repair or exchange under your warranty before bothering to read further.
Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities 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.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

I have a 4 yr. old iMac. I recently got a trojan on it that sent out emails to my address book. I got Norton Internet Security for Mac, and now my Mac is running slow, with way too many spinning beach balls of death. Was it a mistake to install Norton?

There is no such Trojan or other malware known today that will do that using OS X nor has there ever been one. The most probable explanation is that somebody hacked into your e-mail account on the server, so you should change that password to something stronger right away. If it had come from your Mac then there would almost certainly be copies of those messages in your Sent Mail mailbox.

Yours is the first computer I've heard about on these forums that is attempting to run Mavericks with only 2GB of RAM.
Indeed that is acceptable per the Mavericks requirements:

... but as you may know, Apple has not sold computers with as little as 2GB RAM for quite a while.
I suggest therefore you make sure you remove any applications that may be overtaxing your machine. Examples are browsers other than Safari, Mac cleaning products (such as Mac Keeper), or any other non-Apple app that has some startup process running (such as Outlook).

My macpro runs slow with or without internet on..... How can I find out if something is running in the background?

Please boot in safe mode and test. Still slow? If you connect to a wireless network, you may have to connect with Ethernet in safe mode.
After testing, reboot as usual (not in safe mode.)
