Sync trouble with iTunes 10.2.1

I recently upgraded to iTunes 10.2.1 and now get the following message when I plug in my iPod Touch:
"iTunes was unable to load data class information from Sync Services. Reconnect or try again later."
Attempting to sync gives:
"iTunes could not back up the iPod "iPod touch" because the backup session failed."
Any ideas on what's going on?
Thanks,
Andreas

I need to update my profile, as I'm running 10.6.6.
No luck backing up after moving the backup. I still get "iTunes could not back up the iPod because the backup session failed."
I'm seeing errors like this in my system log:

Syncing trouble with iTunes

My iTunes erases and copies about 90% of my music library all over again, every time I use it, which makes me have to sync it for several hours. Can this be avoided?

Never mind, there was no problem with it.

Can you clarify your problem? Are you having trouble restoring your new iPhone from a previous phone's backup? Or are you having trouble logging into iMessage?

Having trouble with Itunes recognizing my Ipad and Iphone.

Hvaing trouble with Itunes recognizing my Ipad & Iphone. When it finally does the siftware will crash when syncing the devise...usually when syncing the Apps. I have removed and reloaded software ,mutiple times.
Any suggestions for correcting this?

I have removed and reloaded software ,mutiple times.
Doublechecking. Have you also tried a complete uninstall of both iTunes and all the other related software components and then a reinstall? If not, try the instructions from the following document:

HHHHHEEEELLLLPPPP!!!! PPPLLLEEEAAASSSEEE!!!!!!

You buy one and only one download.
As it should have been transferred to your computer when you synced, you can contact itunes support and ask for an exception.

I bought an apple iPod 5th generation the other day and I cannot remember the unlock passcode. I have done the restore thing, but because I never set it up or synced it with iTunes, it does not recognize my device. It is disabled for one hour. Please help

I bought an apple iPod 5th generation the other day and I cannot remember the unlock passcode. I have done the restore thing, but because I never set it up or synced it with iTunes, it does not recognize my device. It is disabled for one hour. There's only a few things that could be my passcode, but because it disables for an hour, it is time consuming trying to figure it out. What do I do? I do not care about having to erase everything since it's new and there's nothing on it, but it was never synced with iTunes.

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

How do I get rid of lip-sync issues with iTunes 10.2.2.12?

Hi Everyone.
Firstly, a very Happy Easter!
I'm having lip-sync issues with iTunes playback on my PC. The video is largely smooth with the occaisional choppiness when the CPU is made to work hard. (Playback on my iPod Touch is fine).
The system stats for my PC are at the bottom of the post.
The sound is produced through a Creative Live Sound Blaster Live! 5.1 card.
Video is through a NVIDIA Geforce 6200 with 512Mb of RAM. (All video and audio drivers are up to date).
The physical set-up is that I have iTunes installed on the C drive and my media installed on an external USB hard-drive.This isn't just a problem with 10.2.2.12 - it's been there for the last few updates.
I suppose my main questions are:
Should iTunes and my media be on the same drive? (Which would mean the external drive as I'm short on space on the C drive).
Is there some combination of settings in QuickTime that will solve this? (I've tried different combinations, but it doesn't really help).
Is the spec (below) of my PC causing any issues.
Here's an Easter Egg for anyone able to help!!
All the best

Select *List view* instead of *Album list view*. These are in the View menu or the boxes next to Search, on the right top of iTunes.
and the column next to it with a number in it that I have absolutely no idea what it's for. I want those two columns OUT.
In List view, you can turn off every column (in menu View > View options) except track name.

Since I installed ios 6.1 in my iPhone 4, I can't sync it with iTunes. Can annyone help me? I have already reinstalled iTunes and reseted the iPhone, but it still doesn't sync. Thank you.

Hello Sean,
It sounds like you are constantly needing to restore your phone because it keeps going into recovery mode. Usually putting a device into recovery mode and restoring it can help isolate an issue to your iPhone hardware if an issue persists afterwards. I would try manually putting it into recovery mode and restoring it 1 more time:
If you can't update or restore your iOS device
http://support.apple.com/kb/HT1808
If that does not resolve it the symptoms indicate to me that it is a hardware issue causing this to happen and would seek service for it:

Reset your iPad and see if that helps.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

I am having all kinds of trouble with itunes and updating my ipad. when I open up itunes, it seems to just sit there, never going to itunes store. when I connect my ipad, I check update and it starts, but then I get this message:backup can't be saved on

I am having all kinds of trouble with itunes and updating my ipad. I open itunes up but it doesn't do anything except open to a blank screen. I try to access the itunes store but it won't go there. When I connect my ipad, and try to update it, it starts and then I get a message that says backup cannot be saved on this computer. I have tried everything suggested to no avail. This is the 2nd or 3rd time I have had problems with itunes. Sometimes I even get a message that I am not connected to the internet.
I have uninstalled and re-installed. Any help?

Iphone wifi syncing issue with itunes 10.7

My wife and I each have iphone 4's syncing on our respective computers running Win XP Pro SP3. After upgrading to itunes 10.7 and iOS 6, itunes doesn't reliably sync via wifi. It will sync once then won't a second time unless the computer is rebooted. If I try and click the sync button on itunes, it looks for the displayed iphone then says it can't find it and the iphone disappears.This is happening on both computers. I can direct connect the iphone with usb cable and sync, but it won't sync via wifi without rebooting. I've click the "sync with wifi" button off then on. Nothing works.
We both upgraded to iphone 5's. It didn't solve the problem. I upgraded my computer to a new desktop running Win 8 Pro. Everything transferred fine and the initial sync went well, but the problem persists. After my iphone 5 sync'd with itunes overnight, the next morning it wouldn't sync again via wifi. Again, trying to initiate a sync from itunes caused the it to look for the iphone and not finding it, the iphone disappeared from itunes. Once I restarted Win 8 and itunes, the iphone showed up in itunes.
It's not the iphones(it happened with both 4's and 5's), the computers(two differnet computers) or, the OS( happens with Win XP and Win 8) so it's got to be an isssue with iTunes 10.7 and possibly it's interaction with iOS 6. We didn't have the problem before 10.7 and iOS 6 (upgraded same time).
Any suggestions? This is annoying to not have these reliably sync without intervention.
Thanks,
Z

How can I unlock ipod touch 5th gen currently disabled and never sync'd with itunes

Basic situation. Ipod touch 5th gen. Passcode forgotten and tried too many times such that ipod is disabled and requested to connect to iTunes. Problem is that the ipod was never sync'd with iTunes so the connection fails. I've only owned it for 9 months or so. I know I can recover all my music through iTunes and my applications through the app store since all of my content was legally purchased. The problem is that I need to also recover my contacts and pictures since this is the only place they exist.
I have read about methods up to 4th generation where you can access a particular file on the device via computer and rename it to unlock the device. That would most likely allow me to then sync/backup via iTunes and recover my data. Problem is that I can only access the DCIM folder via windows manager and it contains no data. Perhaps there is a way to access the device a different way?
Is there a way with the 5th generation to either reset the lock (from disabled to locked with a 1 min wait for retry as an example) to allow me more opportunities to try other passcodes that I may have set (including mistypes etc) or to remove the passcode completely and let me set it to something I will write down this time?
Please do not reply with the standard apple responses of 'sync with itunes' or 'factory reset' and no, I did not sync with the icloud either (I tried but it was unsuccessful for some reason).
The answer doesn't even have to be a free one as I would be willing to pay for the solution if it were guaranteed to work. Since apple seems to want to charge for any type of support, even to ask a question, I am relying on the community for help. Thanks much.

You have to place the iPod in Recovery mode as Apple says and erase the device. It is a security feature.
or
If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone and use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
You can also wipe the iOS device by installing the FindMyiPhone app on another iOS device and using that app to wipe the device.
There is not other way
