Itunes Freezes during Sync on 3G & 3GS with Vista 64 & 7-64 all USB ports

To start. I originally had an iPhone 3G over a year ago on this desktop running Windows Vista 64Bit. My phone was able to sync with the PC for about a month and stopped being able to sync. I received many error numbers and put support tickets in with no avail. I then upgraded to an iPhone 3GS. Still under Windows Vista 64Bit and could not Sync my phone. It consistantly froze during the sync process. I tried all USB ports on my PC. People said to try restoring your iPhone and iTunes. I tried that and then got stuck on my restore. I had a broken phone until I was able to sync with my laptop.
I now have the same desktop Acer AM3641-EQ8200A but I am running Windows 7 Ultimate 64bit. I have always had the latest iTunes version, and tried 32 bit and 64 bit versions of iTunes. I still cannot successfully sync my iPhone. If it sits there long enough it will freeze up, start to freeze my computer etc. I decided to try again last night after I got a new USB cord and had the same issue.
In addition, my girlfriends iPod will not sync to the desktop either.
I have been stuck doing syncs on my Netbook for over a year now. Optimization of 3,000+ photos is horrific on it, but it works.
People say to get an external USB that is self powered. Why should I have to do this and chance frying my PC?
The deal is this, the phones won't sync with the desktop but will sync with my netbook also running windows 7 ultimate. All USB drivers are up to date on both.
I have tried Reformatting and Installing Windows. Reinstalling itunes. Updating all drivers. Tried different versions of iTunes. I first called Apple Retail, they had no answer. I wrote apple a lengthy letter with all the Error codes, they said they would call me even though my warranty over the phone support was expired. Never got a call back after they heard my problem.
What can I do to rectify this? I am not the only one out there.

UPDATE:
After putting a USB 2 card in my mac, all worked properly. The problem seems to be using USB 1.1.
This is really tragic because:
+ many Macs don't have USB 2,
+ it is very difficult to find out out if USB 2 exists on your computer (why are no USB 1 or 2 details spelled out in system profiler ?),
+ there are no warnings as to the sort of issues that would be coming up with USB 1.1 (yes I know the specs clearly says USB 2, but it looks like it was working at first),
+ there are no spelled warning by the system (after all, the iTune, iPod combination could detect easily that the incorrect USB standard is being used and warn the user),
+ there does not seem to be specific advantages to use USB 2 (like speed) as the syncing peaked at 6MB/s, a speed achievable with USB 1.1
Come on Apple you can do better than this !

Itunes Freeze during sync

Hi there,
Im operating Windows Vista on a Dell Inspiron e1505 and a 5th generation Ipod 80gb Classic with the latest version of Itunes(9.0.2). I've encountered this problem numerous times and have searched many different locations for an answer. Hopefully someone can provide an answer, or tell me I'm out of luck.
With the amount of music I have I don't have the capacity on my Hard Drive to store it all. Therefore, I choose to manually sync my ipod. However, as I'm syncing, whenever I near 4000 songs on my ipod, Itunes freezes indefinitely, at which point I am forced to disconnect the ipod only to see that all of the music is wiped clean. This occurs during the period where itunes is "determining gapless playback information" of the songs I have just chosen to sync. This occurs whether I have chosen to sync 1 song at a time or 250 songs. The deciding factor is the nearing of 4000 songs.
I've looked around and from what I can determine the answer may lie in the fact that not enough of the "computer's power" is directed to the syncing process; too many background applications perhaps. I've tried turning off anything unnecessary and I run with minimal programs.
Thanks in advance for any help, I'll be happy to try to answer any questions.

That sounds like it might be a library file issue with your iTunes.
If you recreate your iTunes library, are you able to get past the 4000 song barrier when you sync?

ITunes freezing during sync, "Delayed Write Failed"

I've been having a really annoying issue with my iPod Classic 160GB for about two months now. Whenever I try to sync my iPod with my iTunes library, iTunes suddenly freezes completely during the sync. The problem usually appears when the sync is at around 30GB out of 40GB, but it can also appear at other points during the sync.
Sometimes, when iTunes freezes, an error message appears in the right corner of my screen saying, and I'll do my best to translate it from Norwegian:
"Delayed Write/writing failed"
"Windows was unable to save all the data for the file G:\iPodControlArtworkF10281.ithmb. The data was lost. This error may be caused by a failure on your hardware or network connection. Please try to save this file somewhere else"
The freeze leaves me with no choice but to plug my iPod out of the computer when it says on the iPod screen that I'm not supposed to, and this probably isn't good for it.
When I plug my iPod back in, the files that should have been synced up until the delayed write error appeared and iTunes froze and that should have been audio and blue, has turned into orange and "other" on the main iPod page in iTunes.
I've tried everything from the 5 Rs to even calling iPod support where they told me that this was an Apple software issue, and that it had nothing to do with either my iPod or computer. They also told me that I could solve the issue by rolling back to iTunes 7,7 until an update to solve the issue was available. I tried this, and the same problem appeared. I tried to roll back to iTunes 7,6 as well, but no luck there either.
Now I'm getting sort of worried that my one year warranty will expire and I'll be stuck with an iPod that has a software with a really annoying problem.
Any help would be greatly appreciated, thanks in advance.

I am having the EXACT same problem trying to sync my new 80GB Classic with itunes on a Macbook.
I restored and updated to latest ipod firmware. No change.
I updated iTunes to 8.0. No change.
I updated OS X to 10.5.5. No change.
Oddly enough, iTunes freezes to the point where it must be force quit. But it will not quit even then. I have to restart just to get back to a point where itunes will open again.
Help!!

It have taken me all day but it's solved!
During last sync on old MacBook Pro the new version of the iBook app was only synced partly.
That's why, when i was trying to sync on my new MacBook Pro, iTunes was freezing during sync.
Once i have synced my iPhone on the old MacBook Pro again, and iBook app was synced complete, this problem was fixed.

IPod won't sync correctly. iTunes freeze during "Determing Tracks to Sync". Playcounts are a mess now. Please help!'

So since a few months my iPod is starting to get on my nerves. Everytime I try to sync it, my iTunes freezes during the "Determing Tracks to Sync" step. Most of the time it takes a few minutes and then it cancels the sync. I have to sync my ipod atleast 10 times a day to get a song or app on my iPod! One of the most anoyying things tough is, that all playcounts from my iPod sync to my iTunes every time I try to sync. Example: I play Poker Face on my iPod 5 times. I try to sync and my play count says 5 times on my PC. I sync my iPod again and it says 10 times now. It's so anoyying. I restored my iPod already. I removed iTunes and installed it again (And yeah, I deleted it the way Apple wants it). I called Apple and they said I can repair my iPod for 150€, but that's just so much. Any ideas on how to fix my iPod?
Thank you

Hello there,
And welcome to Apple Discussions.
Because you reformatted your computer, your iPod does not recognize the new library because it was synced with the older library you had before reformatting. In order to get the iPod working again, you will have to [Restore|http://support.apple.com/kb/HT1339] the iPod via iTunes. Once you have completed that step, try re-syncing the music and see if that helps.

With the iPhone, you can sync all iTunes content with only one computer. Trying to sync iTunes content with a second computer will result in iTunes erasing the content from the first computer.

What do I do when Itunes freezes during last process of sync

What do I do when Itunes freezes during final steps of sync

Cancel the sync and try again. But, before you do, make sure you have turned off any firewall/anti-virus software you have running. This often is the root cause of failed sync's.

ITunes freezes for minutes at a time with iPad

This is making me crazy! I sync my iPhone('s) and iPods with this computer, and while iTunes may slow down for a few seconds while the iPhone or iPod mounts, it is responsive almost immediately. Update! Now my iPhone freezes iTunes too... this blows!
With the iPad however, iTunes freezes for up to 2 minute with the spinning beach ball and shows up as unresponsive (duh!) in activity monitor. It finally starts synching and while doing so occasionally becomes unresponsive, but the synching finally finishes succesfully... eventually. I have removed and reinstalled iTunes 9.1 according to apple support protocols, but no real change. I have bit rate convert enabled, but it happens regardless of whether or not music is being added or changed. Have repaired permissions, disconnected various other USB devices, but no help so far... Anybody?

Some photo folders in my Windows Photo Gallery are listed in iTunes when I sync my iPhone 3GS but the folders are empty

Some photo folders in my Windows Photo Gallery are listed in iTunes when I sync my iPhone 3GS but the folders are empty. The same photo folders in Windows Photo Gallery are full of photos. How do I fix this?

You may have to try deleting all the music from your phone (by going to Settings>General>Usage>Music, swipping All Music and tapping Delete), then sync it all back on with iTunes in order to fix this.

Itunes freezes when syncing ipod classic 160GB

I just downloaded the new itunes 1.6.1 and everytime i try to sync my ipod classic it gets about a tenth of the way through syncing the songs then completely freezes, i have to exit using task manager and it leaves me with no songs on my ipod. I've tried resetting my ipod and such but none of it has worked, i've spent the last 3 hours looking for a solution but there is nothing out there, please help!!!

Try connecting the iPod Classic to a different USB port set (like the ones on the back of your PC), and make sure you're connecting it directly to the PC, not through a USB hub (like the ones built into keyboards or monitors). If iTunes still freezes, run Windows Update and make sure you update all of the hardware drivers for your PC, especially ones marked "Chipset" or "USB Controller". Frequently, when iTunes freezes mid-sync with a USB device, it's because of an error with your USB controller or that set of ports. The steps above should get you syncing properly again.
If that doesn't work, try connecting your iPod Classic to another PC and sync some songs to it. If iTunes freezes there as well, it may be a problem with your iPod Classic (unlikely, but possible), and would warrant a Genius Bar appointment.
Hope this helps.

My iTunes locks during sync.

My iTunes locks during sync. I am using Windows 7 and iPhone 4s. It almost completes and says "Waiting to copy." I forcibly end iTunes and open again with the same locking problem. I used another cable and the same thing.
Any suggestions?

Check out this thread -> Syncing stays on 'waiting for items to copy' with iOS 5
Some people in that thread suggest unchecking "Include voice memos," just click the iPhone on the left side of iTunes, click Music across the top, then you'll see the voice memo option.
