ITunes playback corrupted after FW 800 drive attached

I suspect this problem is more of a hardware issue than a software issue. But let me describe the problem.
I use iTunes to play mp3 recordings from my Mac Pro desktop with the output through a FW audio device (M-Audio Profire 610). Everything works fine until I attach an external My Passport hard drive connected via FW 800 cable to the computer. As soon as this drive is connected there is immediate static and disruption of the itune playback that gets progressively worse until there is nothing but noise. Disconnecting the external hard drive does not remedy the situation. Neither does restarting iTunes.
The only way to fix the problem is to restart the computer.
Does anyone have any ideas what is happening? The computer is offsite. But when I have time to do some troubleshooting I will try connecting the hard drive with a different FW 800 cable or try connecting with its usb connector. I will also try a different FW 800 device to see if the problem is repeated with a different drive.
John
Edit: Additional information. When I attach this firewire drive to my home computer running iTunes this problem does not occur. It is only with the offsite problematic computer. However, I am not using a FW audio output device on my home computer.

If Aperature is working okay, then there may be no need to reinstall it.
I doubt reinstalling it (or anything else) will delete any preferences. Maybe sone obscure 3rd party apps will write over prefs when reinstalling but I have never heard of any Apple applications deleting prefs when reinstalling.
Reinstalling iTunes will not affect anything. All preferences will be as they were.

I need to restore my iTunes lit file after a hard drive wipe

My laptop was stolen and wiped, but I ended up getting it back. I'm a DJ and manage my music through iTunes and stupidly had not backed up for several months. I've recovered all my files, and am trying to recover my latests itl file so I get my most current version of my playlists back. Problme is, when the frive was wiped, all the itl files lost their names and date created info, and I seem to have over 35 of them. I figured the largest file would be to most recent, but that is not the case. Any ideas on how I can find the most recent itl file out of this group? they range in size from a 65 kb to 45 mb,
Thanks

Well, other is all your personal data. So you'll need to go through that and delete a lot. Also, if you're using a laptop local snapshots may be taking up space in backups.
If you run TM you don't really need local snapshots so if you need the disk space you can disable them in Terminal with this command...
sudo tmutil disablelocal
To undo this, rerun it with "enablelocal" instead of "disablelocal".
Most folks using a small flash drive will keep only the system on that drive and use another larger drive for everything else. It sounds like you need another disk.. but what type Mac are you on?

System lockups/video corruption after adding hard drive

I have a first generation MacPro with an ATI video board. I recently added a 1 TB Western Digital "Black" hard drive, and I used Carbon Copy Cloner to duplicate the first drive onto the Black HD, which is now my new boot drive.
Ever since I did that, my system has become quite unstable and locks up frequently. What typically happens is I'll get a garbled single row of pixels in random places on the screen, and then within a few minutes it will lock up if I try to do anything that is graphics intensive such as using Expose's active screen corders to show my desktop, or opening a folder with dozens of different icons (like the Apps folder). It /seems/ like the problem is compounded when I am using FireFox, but that may simply be because I use it alot.
After the lockup the only way to regain control of the machine is to hold in the power button.
I've even gone as far as removing the original drive thinking that perhaps the system might be confused and is pulling drivers or whatever from the old drive. That didn't help.
Any thoughts as to what is happening here? It's seriously driving me nuts (not to mention wasting a lot of my time constantly having to restart the system).

Did you run Disk Warrior before and after cloning?
Repaired permissions?
Re-ran 10.5.7 combo update?
I'd even look in system profile - memory and see if there are errors showing (doesn't show errors from prior system boots though).
Cleaned out the X1900; add copper cooling kit $29, or look into another ATI card.
Before using any new drive, zero it. And if you have Windows and the drive is backed up or before you put files on it --- do a complete and thorough zero and extended test in Windows using WD's own Diagnostic utility - much better, reliable, and does map out bad blocks while Disk Utility and other OS X tools rarely do. But any new drive... I've had 3 out of 6 need such treatment.
As a test, reboot back on your original why not? I'd have done that just to narrow down the possibilities.

ITunes playback stuttering after a few seconds

iTunes 6.04 worked fine on my computer but when I installed 6.05 iTunes would start stuttering after about 50 seconds or so. I uninstalled and reinstalled 6.04 and it worked fine again. I tried installing iTunes 7.0 and then followed the instructions in:
http://docs.info.apple.com/article.html?artnum=93610
that has been mentioned here several times. Anyone have any idea or am I just screwed?

Besides the steps in the article that you have already followed, please make sure your anti-virus is up to date, and run a scan of your computer.
Another Windows-based PC user has fond removing a virus resolve the issue for him.

ITunes library on an external hard drive - does the HD need to be connected?

Hi,
I want to move my iTunes library from my windows laptop to an external hard drive to free up space. I've read up about how to do it, but the one thing that i still cant figure out is whether my hard drive needs to be continually connected for iTunes to work. Obviously this is not a easy option for a laptop and i want iTunes to work without a hard drive attached. If this is the case, what are my options? I have about 40GB in normal music files, which are being doubled by my iTunes library and taking up too much space on my internal hard drive
Thanks.

I have my iTunes library on my hard drive, but keep a number of mp3's on an external hard drive..but here are some things I looked at to get an idea how to best manage this:

IMac won't boot with SATA external firewire drive attached

I have an 1T Hitachi SATA drive enclosed in a Macally firewire enclosure. If it is attached either in series with other IDE firewire drives or directly, my iMac will boot only to the Apple icon and will not engage the gear icon. If I disconnect the drive the iMac will boot normally with all the other IDE firewire drives attached. I've troubleshot with both Macally and Hitachi, received a replacement enclosure and have an RMA from Hitachi. Before I send the Hitachi back with the possibility of a replacement not fixing the problem, I am asking whether there is a known problem with external SATA drives in particular. TIA. -Dave

I have the same problem exactly but with two firewire 800 drives attached. Both are LaCie d2 500 gb drives. I have tried each one as the first in the series with no luck. I have not tried to connect with any other type of cable.

Not booting with external drive attached after itunes 10 installed.

Since installing itunes 10, my computer will NOT boot into Mac OS X with the external drive attached. It consistently freezes at a grey screen with the apple logo.
If the external drive is powered off, it will boot normally - but slowly. Anyone else with this glitch?

if I forget to UNPLUG the Lacie (by pulling out the Firewire cable), when I boot the Macbook it will give me the Question Mark.
Try opening the Startup Disk panel of System Preferences and redeclaring the startup disk. You could see this behavior if your Mac isn't sure what device to use for booting.

ITunes Library Locked on External Hard Drive after Updating to 10.8.2

Hello. I just updated my iMac to 10.8.2. My iTunes library is located on an external hard drive attached to the iMac. After the update, I tried to open iTunes and I get an error saying that the iTunes library is on a locked disk or I don't have permissions for the folder? Everything worked before the update. Has this happened to any

This probably has nothing to do with Apple, it sounds like your system may be badly corrupt or has some other serious problems. Try some of the troubleshooting techniques in the second half of Understanding upgrade nightmares*.

Many thanks.
With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version):
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

NAS or Firewire 800 drive for iTunes storage?

My iTunes files are currently about 5 or 6 TB of files. I tend to add about 1 to 2TB of media files a year. I have a Netgear ReadyNAS Pro which has 9TB of capacity and has dual gigabit cards (redundant - load balancing) wired via cat6 to a gigabit router. I also have a 8TB LaCie raid big4 quadra which can connect to my iMac 27" via firewire 800. Which would be the better choice for storing my iTunes media AND library files? I have tried storing my library files on the internal 2TB hardrive and the media on an NAS but after a while it begins to create problems so I want to have everything on one drive.
The house is all networked via wired cat6 and there are 4 apple tv's streaming the media files. Since they need iTunes to stream, it still has to go through the iMac as an intermediary and can't use the NAS directly.
Anyone have concrete opinions about or experience with this?
Thanks

First.................BACK UP ALL YOUR MUSIC
now you can play around, moving your iTunes library is pretty simple.
In Prefernces>Advanced there's a box at the top showing the 'iTunes music folder location' and a button next to it saying 'change'.
Now, before you change the iTunes music folder (basically your librabry) you need to move the actual files. So create a folder your external hard drive ('music' or something) then find your current iTunes folder in Home>Music. In that folder there are 3 files you have to move; the 'iTunes music' folder, the 'iTunes Library' file and the 'iTunes Music Library.xml' file.
The Folder has all your music and the other two contain information such as playlists.
It's as simple as moving (not copying, unless you want to for safe keeping) those 3 things (make sure iTunes is closed) to your external drive, to the folder you created earlier. When that done re-open iTunes go to Preferences>Advanced click to Change button up the top. That will open up the Finder Browser, just navigate to that folder on your external drive and select it. Make sure you select the actual folder, not the whole external hard drive OR the contents of the folder.
Quit and re-open iTunes all your music should be back to normal, and any songs you import or add from now on will go into the music folder on the external HD.

Itunes corrupted after update. asking to reinstall itunes

After I updated my itunes i clicked to open it an this message appears.
This copy of itunes is corrupted or not installed correctly. Please reinstall itunes.
My mac is. Mac book pro 5, mac os x version 10.6.8
Please help!!

Just had this problem myself.
Here's the fix.
1: Restart your computer and hold Command + R
This will take you to a screen with roughly 4 options. Choose Disk Utility.
2. Using the "first aid" option, choose the hard drive and then hit repair disk (on mine, there was a hard drive, and a subquent one underneath, I repaired both).
3. NOTE! The first time I did this, it failed and said something along the lines of "reinstall your OS, etc....". I just restarted my computer and repeated steps 1-2.
4. Upon doing this a second time, the disk was repaired, I restarted again to get to my home screen, Wait ~40 minutes for spotlight to finish indexing, your computer will run slow until spotlight finished indexing so just let it do its thing.
5. Uninstall Itunes by dragging to trash bin and erasing.
6. Reinstall Itunes from the itunes website, for me, all my music was saved and I did no special steps, so I imagine it will be the same for you.
Hopefully this works for you!

I have itunes directory on an external hard drive and want to direct a new installation of itunes on windows 8 to use it. I tried holding down ctrl and clicking itunes and after many tries got it to work one time. When I went back in later it had reverted back to a blank version of itunes and I cant get ctrl to work again. Any other ideas?

This is sometimes caused by a problem with the iTunesPrefs.xml file, normally found at C:\Users\<User>\AppData\Local\Apple Computer\iTunes\iTunesPrefs.xml. Try dragging this to the desktop and trying again.
Alternatively the problem may be that you have McAfee AV and it is preventing iTunes from updating the same file and thus causing the problem. See Why does iTunes delete my itunesprefs.xml? for details.

Why does iTunes freeze up for minutes at a time when modifying INFO (CMD-i) ? My files are not corrupted after it is done like many other threads i have readed.

I am running the latest iTunes, the latest updates to the OS and on an iMac 3.4GHz Quad core i7 with 8GB of RAM and the music stored on local HDD.
