Same problem here.. Issue is itunes doesn't work with 64bit windows.. See my post here
please go here and submit a bug report.. Only way we are going to get Apple to fix
I'm seeing the same problem with my iPod Nano 3G and Windows 7 x64. It syncs OK when the Nano is first plugged in, but if I leave it plugged in it will either disappear in iTunes or, if it is still showing, I'm unable to successfully sync. (iTunes still thinks the iPod is connected, but the iPod doesn't act like it is connected on its screen.) The only way I've been able to successfully sync is to unplug/replug the Nano each time.
I have an iPod Touch 2G that syncs flawlessly. I suspect the problem might be with how Windows sees the Nano and older iPods as a type of removable storage device.
Hey guys! I was in the same boat as all of you, but I was sure their had to be a solution to this problem. I found a solution that worked for me! Ive got the Windows 7 64bit, and my ipod is sycning as we speak! Follow these steps.
1. Disconnect your iPod Shuffle from your PC
2. Press CTRL-ALT-DEL, start the Task-Manager, go to Processes and end the process for "ITunesHelper.exe" (this will prevent iTunes from starting when you re-connect the Shuffle.
3. Now, re-connect the iPod Shuffle - iTunes should NOT start by itself and you should be able to see your Shuffle within the list of your drives (My Computer.
4. Next, download SharePod from http://www.getsharepod.com/download/ and extract the .zip file and start the Sharepod.exe
5. If everything works out, Sharepod will recognize your iPod Shuffle
6. Sharpod won't start if iTunes is open but it will work vice-versa. So, start iTunes NOW and keep Sharepod OPEN.
7. iTunes will re-detect your Shuffle but it will still be available as a hard-drive afterwards as long as you keep Sharepod OPEN. Detection can take up to 30 seconds so be patient.
8. Now go to the iPod Summary tab within iTunes and DESELECT "open itunes when this ipod is attached". Scroll down on the same page and also check the "enable disk use" checkbox. Click the contents tab, then the settings button and choose the amount of disk space to allocate. I chose 5MB. Click back to the settings tab and APPLY those changes.
9. Close iTunes WITHOUT ejecting the iPod.
10. Close Sharepod and simply disconnect your iPod Shuffle (i.e. pull it off the dock).
11. Reboot your computer. After the reboot ITunesHelper.exe will be running again you don't have to care about Sharepod or processes anymore. That is, you can delete sharepod if you want.
12. Simply connect your iPod to the PC as you used to do, open up iTunes and everything should work as it did back in the good old days.
NOTE: Don't eject the iPod from within iTunes going forward, simply disconnect it from the PC manually by pulling it off the dock yourself when you're done.
This solved my sync issues, and I hope it does for you too.
I had a problem syncing with my iPod Touch 2G. For me, it was a driver problem.
First, connect your iPod to USB. Start Device Manager. Under Portable Devices, right-click on Apple iPod, select Update Driver Software, then Browse my computer for driver software. Enter C:\ into the type-in box, then press Next. Windows will find the updated driver. Dis-connect and re-connect your iPod. That's all it took to get my Touch syncing again. Good luck.
Add another person with this problem. Really annoying, done everything I can think of to make it work, even tried a 3rd party driver to make WMP recognize the ipod and sync with it. Seemed to be working well initially, but then WMP player started behaving the same as iTunes did. Couldn't close it or anything, had to force it down and then restart the computer to make it useable again.
I did a lot more research and came up with a solution that worked for me. It's apparently a problem with the NVidia driver for my system coupled with the 64bit flavor of Win7. Microsoft is working on a fix, but it's probably going to go out as a Hotfix linked to a knowledge base article, and not as part of Windows Update.
So, my suggestion to people having this problem is to check the workaround posted by MS here: http://social.technet.microsoft.com/Forums/en-US/w7itprohardware/thread/3aae3b66 -6a1a-47e8-ad1b-b20b68eaecf8#79ea3219-d76e-40bc-b910-c7d347002e66
If it works for you, then keep an eye on that thread for when the actual fix is posted.

I can't even get iTunes to open most of the time. I've about had enough. Problem is, it's not just an iPod issue; I use an iPhone and must sync up for firmware updates. iTunes is the worst and one of the best programs I've used. I've purchased, lost and repurchased tons of music. Please Apple, give us a break. You sell plenty of Apple computers and devices. Can't you leave PCer's alone and make your programs compatible? What's your problem?
