IPhone Freeze during Sync (itunes 7.4.2, or OSX 10.4.10?)

Ok, a few seconds into my sync, my iPhone freezes.
the animation on the words "slide to cancel" stops and I can't slide the slider to stop the sync. the only way to get the iphone back is to do a reset.
I think that I have not been able to sync since upgrading to itunes 7.4.2, or osx 10.4.10.
when I go to preferences it does not list any iphones backed up on this computer, even though I have synced this iphone to this computer before.
any ideas? I'm on firmware 1.0.2 but I'm afraid to upgrade until I do a sync that works!!!
I also

I have been having this same issue for over a month.
Took it to the Genius Bar @ my local Apple Store, they replaced it.
Sync went fine, then went to create ringtones and it froze.
I called Apple support line, got their top tech after two other people failed, spoke
for over an hour. Came away with no more sync issues.
A week later I went to sync using 1.1.1, OK , put in dock few days later and its freezing again !

I just emailed the one note to myself and solved the issue.

I'm unable to transfer my contacts to my iPhone 3G during an iTunes sync. Other content appears to be syncing OK and all my ios5 devices are working fine! Can anybody help?

I'm unable to transfer my contacts to my IPhone 3G (latest ios 4.2.1 installed) during an iTunes sync. All other content appears to sync OK and my ios5 devices (iPhone 4s and iPad 2) are syncing fine. I suspect this could be an iCloud issue as my iPhone 3G is not compatible with iCloud. Can anyone help me out with this issue?

I solved this issue by turning off iCloud contacts sync - then my iPhone 3G would sync through iTunes as normal. I then just turned iCloud contacts sync back on. Job done!

IPhone freezes on sync during back up

My iPhone freezes when I sync. Before updating to 3.0 it would freeze when transferring purchases.
Specifically the dictionary.com app. I removed that app and it seemed to work. But after updating, I don't
even get to the transferring purchases. It starts to back up then freeezes. Don't want to lose all my purchases.
If I cancel the backup it seems to synch the mail, contacts, etc. Just fine. Thoughts? Thanks.

Do you have the latest version of iTunes?

Itunes and ipod freeze during sync

hello,
firstly, i would like to thank all you kind souls who post to this forum with very helpful suggestions. you have helped me with many past difficulties.
my present issue concerns transferring songs from itunes to my ipod (4th generation). here's the story:
on friday, my ipod started acting funny (skipping songs, etc.). by saturday, it would no longer do anything (folder with !, resetting did not help). this had happened to me before so i did not freak out and figured i just had to restore (that had worked the first time around). however, when i plugged in my ipod to my computer (powerbook g4, just three weeks old), it was not recognised and i was prompted to initialize the disk. i then came to this forum and read pretty much everything related to this kind of problem. countless resets, erases, partitions, etc., later, i was able to get the ipod software back on the ipod. it seemed all normal but there was no music on it (makes sense since i'd restored it). but then...when i plugged in my ipod to sync it with itunes, it would freeze at a given song (not always the same one, sometimes 31 songs into it, sometimes 500). i came back to this forum and read that i should reset my ports, which i did. didn't help, the sync still freezes both the ipod and itunes.
so that's where i'm at: i have the ipod software on the ipod, but i can't sync it with itunes (i.e. i can't get my music onto it). my brother thinks i have bad blocks (or sectors). is this a possibility? the ipod does make some noise (not sure whether it's the infamous clicking...).
so here are my questions:
1) is there anything i haven't done yet that could get the ipod to sync with itunes?
assuming i have done everything and the problem is with my ipod's hard disk:
2) would a program like disk warrior potentially be able to fix the ipod?
3) would it cost me less to have the ipod serviced than to buy disk warrior?
4) is there somekind of open-source or freeware disk repair utility that could perhaps repair my ipod's disk?
thanks for reading and i really look forward to any suggestions.
gen
p.s. the ipod's more than a year old, so no longer under warranty.

Okay, I got it to work tonight...
My U2 iPod would freeze while syncing. I restored and tried to sync and it would freeze on different song #'s. All the while I heard a clicking sound coming from the drive that I never noticed before. It would just click once in a while, not repeatedly.
My fix: (a version of the carpet drop) While the iPod was on and spinning, I held it tight with my right hand, facing me and smacked it's side into the palm of my left hand, simulating the amount of force that it would incurr from a waist-high drop onto carpet.
Now, this force was sheer approximation, being that it would be too time consuming and difficult to calculate this exact amount of force. I mean, my waist may be higher/lower than the original carpet-dropper, and not to mention the plushness of the carpet! Who knows if he did it on Shenandoah Shagg or maybe just some Bermuda Burr Rug?!
By the way, the problem started after being left out in the car on recent cold nights... hmmmm, my iPod thinks me a jerk.
Anyways, here are some previous attempts at fixing my situation (in no particular order):
1) restored from 5 different iPod updates (2004-11-15, 2005-02-22, 2005-06-26, 2005-09-23, 2005-11-17)
2) tried to fix with Disk Utility
3) tried to fix with Tech Tool Pro
4) tried to fix with Disk Warrior
5) tried to initialize multiple time (even writing zeroes)
6) manual sync

IPhone freezes when sync is in 'backup' stage

I recently started getting freezes every time I sync. Its very predictable:
connect iPhone
sync begins
sync starts to 'backup'
iphone freezes
This happens regardless if its a automatic sync or if I turn that off and do it manually. The only way to sync is to bypass the backup step by changing sync settings and hitting apply.
Sometimes if I delete the backup and it has to make a fresh one it will work, but the last time I tried this it did not (first time it failed to work).
I called apple and they had no idea and said it needs service. I can't test it on a different Mac...maybe user account...so I'm not sure if its a software thing with my system.
FYI...I have restarted, reset, reinstalled re-everything. I have done all the usual steps. NO matter how much or how little data I sync, it freezes so turning off photos/music/etc does not work.
Any ideas?

I have the exact same problem. In a different thread I have found a partial solution; it will do an automatic sync without the "apply" trick but it will not make a back up:
http://discussions.apple.com/thread.jspa?messageID=6406167
"The only way around this is to disable backups. You can force this by
moving the backup agent from its location at
/System/Library/PrivateFrameworks/MobileDevice.framework/Resources/
AppleMobileDeviceHelper.app/Contents/Resources/AppleMobileBackup
You should then be able to sync with your iPhone again, but
unfortunately it won't get backed up."
Dannys1 wrote:
Remove the AppleMobileDevice app as instructed, copy it to another folder and trash the one in the app.
Plug in phone and click sync...it will say its taking a backup still (if it does i have no idea, but in my itunes it said it made one) i clicked a few options around and press sync again a few times.
Then i copied he AppleMobileDevice back in again, disconnected the phone and reconnected...and now it works properly! It backs up every time, ive tried unplugging and reconnecting and it works everytime. I even have automatic sync ticked and the backup works everytime.
It appears we just needed to remove this AppleMobileDevice, then whatever issues Itunes was having during backup no longer happen when you click sync..excellent! and no need to erase all from phone!"
But that didn't work for me.
Any help very welcome!

The iPhone cannot be synced. iTunes crashing.

There seems to be a whole “bunch of stuff” going on with my iMac 21” i3, and I just wanted to check in to see if anyone had experienced anything similar or had any advice.
First, when syncing my iPhone 4 last week I got this message:
"The iPhone cannot be synced. The disk could not be read from or written to."
iTunes at the same time was freezing up, so I forced quit (silly perhaps).
When I restarted iTunes I got this:
“iTunes Library does not appear to be a valid iTunes library file. iTunes has created a new iTunes library and renamed the file to "iTunes Library(Damaged)"
Some research some frustration and some time got my iTunes back up and running.
I was still getting the "The iPhone cannot be synced. The disk could not be read from or written to." When attempting to sync by iPhone.
Finally I found a fix that worked online (not syncing photos!).
So that should be the end of the story.
But since then iTunes has been running SLLLLOOOOOWW, as has my system as a whole.
Then last night:
"The iPhone cannot be synced. The disk could not be read from or written to."
Followed by:
“iTunes Library does not appear to be a valid iTunes library file. iTunes has created a new iTunes library and renamed the file to "iTunes Library(Damaged)"
So something be wack!
The only thing I could think of is I got an email from Apple telling me they needed to replace my hard drive free of charge as they were found to be faulty.
I’ve booked in with the Apple Store to have the drive replaced. But could it be the problem? Or do I have something else happening here.

HT201210 iPhone freezing during restore.....

My iPhone 4 keeps freezing about 60% way through a restore, according to iTunes when the firmware is being updated. Any ideas how to fix? I have tried a different computer, disabling my security software etc. and still no luck :o( (Windows)

I was doing exactly what you suggested for hours prior to posting my question. I tried restoring, I tried restore/update over and over and it would always freeze between 25-75% through. I restarted my laptop 20 times, uninstalled and reinstalled itunes 4 times. Finally, today I was so frustrated that when I saw it freeze up one more time, I just pulled the power cord out of my laptop and walked away. An hour later I booted back up and set it to restore before I left the room and ....magic, it finally worked. Whether the unplug event had any real connection, I don't know.
If anyone does freeze during an update and has the "connect to itunes screen with the red itunes logo" stuck on their iphone screen, modular 747 is correct. Just keep trying the restore/update through itunes, but be prepared to do it non-stop for almost 72 hours like I did.

IPhone will not sync iTunes and iPhoto

Just bought an iPhone a couple weeks ago. No problems transferring (sync) iTunes and iPhoto (and everything else) on day 1. Now looking to sync a second time and no luck. When I connect iPhone to my MacBookPro, iTunes and iPhoto automatically open but no sync. And under File >> in iTunes, there is no option to sync iPhone. I have tried restarting computer, restarting iPhone, trying both ISB ports on the computer (the basic troubleshooting in the manual). Again, iTunes and iPhoto open automatically as if it wants to sync, but does not. Any suggestions ? Sorry if this is a common problem. I could not find it with a cursory search. Thanks.

Try downloading the current iTunes version and re-install it over the existing. No need to delete iTunes on your computer first.

160GB ipod freezes during sync

I am trying to resync all of my songs & videos from Itunes to a 160GB ipod. When it gets to about 4GB, the ipod freezes and sync stops. I have tried resetting the Ipod, but it doesn't help. Any ideas?

I having a similar problem. Sometimes while my ipod is syncing or when I am deleting something, it freezes. I cannot close it at all. It doesn't effect the rest of the computer. I cannot get rid of it unless I restart the computer and I can't keep doing it, its becoming an annoyance. I've reinstalled 4 times and it doesn't seem to be working. PLEASE HELP!

ITunes freezing during sync with iPhone 4s running iOS7

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 !

Iphone freezes during restore - should I re-install itunes?

I downloaded iTunes to a new computer today. I synced my iphone and then tried to update the software. Each time I go through this process however, it freezes at the same spot. I'm trying to restore my phone and I can't complete the process. If I delete iTunes and re-install it, will I lose all of the information that was synced? My last computer died and I'm unable to get old sync information off of that. I have no back-up calendar or contacts. Any suggestions?
I have been working on this for 3 hours now and I use my phone as my alarm clock and I am laughing at how I'm going to figure out how to get up tomorrow. Can someone call me? No. Phone won't turn on past the plug into iTunes logo. Maybe I should have just kept a landline, datebook and alarm clock. Please help!

Arafatsapey, dead wrong. The current iTunes for for windows is compatible with:
Windows System Requirements
PC with a 1GHz Intel or AMD processor and 512MB of RAM
Windows XP Service Pack 2 or later, 32-bit editions of Windows Vista, Windows 7, or Windows 8
64-bit editions of Windows Vista, Windows 7, or Windows 8 require the iTunes 64-bit installer
400MB of available disk space
Broadband Internet connection to use the iTunes Store

Yudna, I would install the latest iTunes if not already installed
