Unkown Error 13001 occurs when loading iTunes 8

What do you mean when you say you move your library?

Just a thought...
If your library databases are on an external drive, have you tried a shift key start?
Hold down the shift key, start iTunes, keep holding the shift key until you are asked to choose a library, navigate to the iTunes folder on the external drive and choose iTunes Library.itl.

If I understand you correctly, iTunes will open normally if you force it to create an empty library by moving iTunes Library.itl

What do you do after that, do you add your files again to the new library, or do you put back the old itl file?

I am interested in if iTunes starts to crash after you add tracks to the new library, but not before. If so you might have a content related issue.

I have set my iTune library aside (safely out of the way), and deleted EVERYTHING else related to iTunes and re-downloaded 8 and re-installed it -- several times. Doesn't work. I set up a new account and it worked there for a day or two and then I started getting the same error.

I am having the same problem!!! It all started after I loaded ITunes 8.0.

I have most of my music on my external HD. I know how to switch from the music on my powerbook's HD to the music on my external HD by holding down option key while opening ITunes. Since I added 8.0. I am able to open the ITunes folder on my powerbook, but when I try to open the folder on my external HD by using the option key and choosing the ITunes folder on this drive (which always worked in the past) I get this 130001 Error message.

Can anyone help me with this? There must be a glitch in the new software. HELP!!!!!!!!

I have exactly the same problem.
Tried already everything, also opening an itunes library from the folder "previous libraries" , but still I got an unknown error 13001 back. When I use a blank itunes library nothing wrong. I reinstalled 7.7.1 and everything went perfect. I prefer itunes 8.0 because it seems that iphone firmware 2.1 needs itunes 8.0
Can anybody help me?

I analysed the problem but It cannot be a corrupt itunes library.
I have my itunes-library on a special partition and that seems to be the problem, since when I place that library in the ~/music folder on the same partition as the system and subsequently the itunes program then the library can be read. So it seems a problem in the itunes software in locating a library on an external drive or partition.
Has anyone figured out the cause or solution?

I had the same problem after updating my computers to iTunes 8, waited and hoped that the latest update 8.0.1 would solve the problem. It didn't, so I tried a few different things. I copied my iTunes library to another external HD and discovered that the library would open without the Unknown Error 13001 message. I reformatted the problem external HD to OS Extended (Journaled) then copied the iTunes library back to the drive. Still got the Unknown Error 13001 message.

What solved the problem was to rename my external HD. Originally it had the name: *17" PowerBook Backup* After renaming the drive PowerBook Backup I was able to open the iTunes library, so it's possibly a character in the drive name not being recognized by iTunes 8.

I was getting the same error message when I tried to move my iTunes folder to an external drive. When I changed the name of the drive from 17" iMac Shared Volume to iMac Shared Volume, everything started working. Evidently iTunes doesn't like the " symbol in drive names.

I added a 1Tb hard drive and partitioned it, labeling each partition as a letter drive ("A", "B", etc.) Then when I moved my iTunes library onto "E" in order to gain space - I started getting Unknown Error 13001. Spent half a day trying to resolve, including reinstalling iTunes. Got some advice to check "Discussion" - erased the quote marks on my partion labels, and 5 minutes later all was well and working correctly.

BTW I've seen some advice that states to hold the 'Shift' key when opening iTunes to direct it to the new library location. I believe the correct key is the 'Option' key - anyway it worked for me.

Am I the only one loosing his patience with apple's inability to participate in these on-line requests for help and info??
what the fvck apple???
if i loose my itunes data one more time i'm coming to infinite loop.

my issue is NOT related to having data on an external volume because it's on the native hard drive.
i encounter the 13001 not upon opening itunes but rather when simple additions or changes are made.

Has any body sorted this out yet? Its flipping annoying.

Come on Apple sort it out.
