Windows 7 - Itunes x64/Ipod Classic Sync issue

I can not for the life of me figure this out......

Running windows 7 x64 build 7100, itunes x64.
My ipod classic gen 5 80 gb will not sync in itunes unless usb 2.0 is turned off by disabling standard enhanced pci to usb host controller in device manager. Itunes freezes during sysnc while ipod ejects itself forcing me to restart pc. tried numerous cables, numerous uninstall reinstall. When i disable apple mobile device support the ipod will remain mounted, however i can not sync with ipod due to the fact that it is missing the drivers. itunes wants to install in x86 file, have tried this as well as manually placing in x64 program files. talked to supervisor at apple, recommended i comp. clean every stentch of apple from computer and re install itunes x64 while manually directing it to 64 bit program files. to no avail. i tried installing 32 bit drivers as well win7x64 would not take to them. PLEASE HELP.
note: my library is on external hdd....but i have no f'n idea how to move it and it is too big.

Running iTunes in Vista compatibility mode fixed all my sync issues in Windows 7.

yeah that doesn't work, tried many times. it just ejects when it starts to sync

ok so now i have figured out it was due to my library being on an external, is there any remedy to this? it syncs right up when my library is on the c:. but my library is big so i don't think this is going to work for me!

Use Winamp. At least that works.
The last time i tried to use iTunes was on a mates' computer and all i did to crash it was drop 1.2gb of audio files into the library...

Which in any real software solution, doesn't mean an immediate freeze, but rather a quick indexing of teh 1.2gb of songs i just dragged and dropped.

Honestly though, iTunes is hated for a reason. It deserves the hate.
The only software i've seen programmed worse than iTunes is STEAM.

I am seeing the exact same issue with the exact same configuration. No luck so far. Win7 RC1 iTunes Sync Problem « Wholly Mackerell

I also have this same issue, has any one managed to solve it yet? I have just upgraded to the newest version of itunes 8.2.0.23 but this has not fixed it.

My itunes library is also on a drive other than C (not external though), and really I would like to keep it there. The same configuration worked fine under vista.

I am also having issues with f**in itunes syncing, but my library is on C: I plug in it syncs for all of 19 seconds and then says ok to disconnect all would be great if i was able to get my selected songs on my 120gb ipod I managed to get 30 gb on but now when i select sync only checked songs and misc... it hangs and freezes and CPU jumps to 78%-100% and puter freezes what gives it is becoming very annoying so I called apple care and they told me there are numerous bugs in itunes 8.2 they have no plans to debug at this time and it is supposedly not compatible with the RC-7100 at all sux because i have 70gb of music to sync and media monkey works but when itunes decides to sync it wipes all 70 out because all my mp3 have been imported into media monkey, I give up!! I might be forced to uninstall the rc and go back to vista,

Also cannot sync shuffle gen2 on Win 7 x64 build 7201 with Itunes 8.2 x64

I've been having the same problem i finally found a workaround, just use winamp in vista compatibility mode instead of itunes
