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

Ipod freezes during sync then error that it cant read file...

A little pre-info... I have owned a black 30gb 5th gen (video) Ipod for a couple of years now. I plug it in fine, my computer recognizes it fine, Itunes works fine with it... everything works great.
I just bought another Ipod off ebay that is exact as mine except white- auction states the Ipod works fine, seller has awesome feedback, etc.. I bought this for a gift for my sister for Christmas. It is second hand, so warranty is expired.
I plug it in the computer, and first tried to transfer some normal text data via explorer. I had put this same data on my own black Ipod with no issues, words fine. The white? Lo and behold I get that "Data Cycle Redundancy" error during copy. My experience is that that has always meant that the original file is messed up, not the destination its being copied too... but in this case I know the original file(s) were/are ok.
And the Ipod freezes. So I safely unplug, and try to hard reset it. It wouldnt for a bit, and I noticed the Ipod was rather warm (but this might be because it was frozen for several minutes with the backlight still on as well). Finally I get it to reset. Same stuff happens again, again its hard to reset.
So then I decide screw it, forget adding the stuff via explorer, Ill just try to get the music on my computer at least, over via Itunes, after I first restore the Ipod.
Itunes opens... recognizes the Ipod... I go to copy music, and it copies until it essentially 'freezes'. I tried many times - its not a bad file because the same file would copy the other times Id try. It would freeze on any random file, during the write process.
Then Itunes comes up with this error:
"the ipod cannot be synced. the required file cannot be found"
I dont think this is referring to my files trying to be copied, they werent deleted or moved from their location since importing into the Itunes library. Im wondering if theres a system type file on the Ipod that Itunes speaks to as it transfers...and when the Ipod freezes... hence it cant be found...
At the same time I get this error from Itunes, I get a Windows XP bubble pop up that says:
"Delayed Write Failed - Windows was unable to save all the data for the file x. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere."
Now again, my computer/windows is NOT the issue. Its the Ipod.
All the advice I have searched says to fix things on my computer. That includes that Apple support page in regards to those errors - it points the finger at my USB ports, etc - and thats simply not the case. If it was, my other Ipod wouldnt be working either - nor would my flash drives.
Its the white Ipod.
I saw one site suggest to format the Ipod via Windows first, then do the Itunes restore, but the Ipod froze and Windows couldnt format.
I went into Device Manager and compared the two Ipod settings, both share the same settings. They are not set on 'enable write cache'.
I have tested the HD via Diagnostics, and the BL blinked after the test, showing the HD passed... so right now I can only think of three things... a bad logic board perhaps, or the Ipod system files are corrupt somehow no matter how many times I do the restore... should I revert to an older update; is that even possible. Or the HD is bad after all and its just being missed in the test.
So now... I need help. Am I missing something important? Is it a simple fix... a corrupt file thats freezing the Ipod somewhere - or did I get a bad Ipod from the seller.
Its so close to Christmas, if there was some simple fix(instead of it being a bad HD) I could fix it myself, Id rather do that than go through the hassle of returns/refunds. Not to mention, its always a gamble how the seller will react. Will they help, or say its not a problem on their end and try to screw me... then Ill have to go through Paypal for reimbursement and that takes 90 days at least...

I wish I had good news but all I have is information. I have access to 4 5th gen ipods. 2 black 30s and 1 white 30 and 1 black 80. The one white and one of the blacks work and have worked flawlessly for the past two years. The other black 30 and 80 started having the issue mentioned here some time after upgrading to iTunes 8. I tried to lowlevel format the iPod drive to fix any issues and that didn't cure the problem. I bought a MacBook a couple of months ago and restored my ipod to Mac format and low and behold it would accept files again! However it wouldn't let me fill the ipod beyond about halfway, this was on both ipods. Now the ipods have become slowly less and less fillable. Seems like syncing rather than putting the songs on manually seems to help, but again its getting worse all the time. (the two ipods that don't have any problems belong to my girls and the problem ones belong to my son and i) <- Grasping at straws I know, but my son and I are constantly changing the songs, playlists, videos and such.
When I bought my Mac the guys at the Apple store were shocked that I was having this problem and practically begged me to bring it in so they could see what it wrong with it. I will post an update when i do that.

ITunes and computer freezes when syncing

My iPod and iTunes work fine separately, but when I sync my iPod, it'll sync a couple songs/photos/videos and then suddenly freeze which freezes my entire task bar. I use windows vista and itunes 7.6.1 and I haven't had this problem before.. What's the deal?

I have this exact same problem and cannot figure out a solution to it. It has happened twice to me.
First time it happened was around Christmas. All of a sudden, I could not sync the iPod any more as my system froze when attempting to do so. iPod and iTunes worked fine apart. I dug through the whole system and could never get it to work. The only thing that I could do was to move everything to a different box. I lost all of my history in doing that, though.
Now, in the past couple of days, the same issue has started again on the 2nd box. I've reinstalled iTunes, I've started everything with a base config (only required system services running), I've tried old iTunes libraries...nothing works, it still syncs for a bit and then everything freezes. I enabled disk use and then ran a disk check on the iPod. It found some errors and corrected them. I guess I could erase the iPode to factory standards and then try syncing again, but I did this when the issue occurred the first time and it didn't solve the problem.
Any insight anyone can give into this issue would be greatly appreciated.

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!

HELP --- iTunes and iPod freeze

I'm hoping someone can help me with this....I have an ipod Photo (using windows xp) and everytime I add music to my ipod, say 15 songs, itunes will freeze as soon as it finishes adding the songs. I get the "not responding," "error" prompt and have to close itunes and disconnect my ipod just to have it do it all over again. If I re-open itunes without disconnecting and reconnecting my ipod, itunes says it can't read the ipod. This is really annoying because everytime I want to add songs I have to go through this whole process. Does anyone know what I am talking about??? Thanks in advance for any tips you can give me.

krakrjak,

IPod freezes during sync every time

I've had my iPod fifth gen. for around two years now and it's only been recently that when i went to sync my songs it's unable to do so. I have all the latest software including for my iPod and iTunes. The iPod seems to be freezing when it reaches 3.99gb full of music. I've gone through the 5R's but to no avail, does anyone have any suggestions?

It can be some bad sectors on the hard drive of your iPod - which causing the problem. Try to do the following and hope it helps
For Mac computer
1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
5. Eject your iPod and do a Reset
6. Open the iTunes 7 and click “Restore”
For Window computer
Go to folder “My Computer”
Hope you can see your iPod there and right click on the iPod
Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
Now select “Format”
Eject your iPod and do a Reset
Open the iTunes 7 and click “Restore”

ITunes and ipod do not sync after loading itunes 10.3.1

The system gets stuck on "verifying your ipod". The Windows 7/64 bit is now recognizing my ipod as a USB mass storage device. Is there anyway to make sure this doesn't happen again. Each time there is an upgrade my iTunes does not sync with my ipod, it crashes with not being able to update my library with not enough memory and my windows operating system recognizes my ipod as a USB mass storage device.
This has happen for every upgrade and its not fair!!!
Each time i've had to uninstall the the upgrade, rename my itunes library then reinstall and it begins to work again. This time it did not work. Does someone have another solution?
I cannot restore my ipod because iTunes freezes and then shuts down.

Basics from the manual are restart, reset, restore from backup, restore as new.
Try restart.
If that fails to solve the issue, try reset, and so on.

How do i get my itunes and ipod classic to sync on new computer?

I just got a new laptop and transferred my songs to it. Some of my playlists did not make it over, but are still on my ipod classic. When i connect my ipod classic to the laptop and try to sync, itunes tells me that it will erase all data and then sync it. I do not want to lose my playlists. Any suggestions?

If you transfer your complete iTunes data from your old computer to your new computer, the iTunes library on the new computer is the same iTunes library that was on the old computer. All of your playlists (as well as other supporting data such as ratings and play count) will be there, and your iPod will treat like it as the same iTunes library. What you probably did is move your iTunes media files (such as song files) and added them to a new iTunes library on the new computer.
So, if you still have access to your old computer, with its iTunes library intact, you may want to do the transfer again, following the procedure described here
Back up your iTunes library by copying it to an external drive - Apple Support
There are many steps, but to summarize: (1) Consolidate all of your iTunes user data so that it's in one place, your iTunes folder. (2) Copy that iTunes folder to an external drive. (3) Install iTunes on the new computer (and while iTunes is NOT running), replace the existing iTunes folder with the one from the old computer (on the external drive). When iTunes runs, it uses your old iTunes folder.
Otherwise, if your iPod is the only source available, iTunes syncing is generally in one direction only, from the computer's iTunes library to the iPod, NOT from iPod to computer. However, there are third party methods and utilities that can transfer from iPod to computer. If you do an Internet search on something like "ipod transfer," you should get some links. Some utilities may recover playlist data.

ITunes and iPod Classic Freeze: How Can I Avoid It???

Sorry if this should have been a part of the longer iTunes and iPods freeze discussion string.
My 80g Classic is in the mail and due to arrive on Friday. I ordered directly from Apple (for the engraving but obviously not as easy to return).
After reading all the discussion about the iTunes freezing issue I have a few questions of my own:
I have Windows 2000 at work, Windows XP on desktop at home and Windows Vista on my laptop. My entire library (combination of original home desktop, smaller work library and a few songs even purchased on laptop) is on external hard drive that I use with laptop.
Which computer should I connect my new iPod to first? My preference is work since the iPod is being shipped here. It arrives on Friday and I want to start using it on a road trip on Saturday.
I'm a Manage Manually kind of guy especially since I have music on three different authorized computers.
Any tips or suggestions that you think will help me PRIOR to actually trying to connect iPod with iTunes would be greatly appreciated!

NO answer is my answer. I guess I can't avoid it. Thankfully I learned to look at the box that says not compatable with Windows 2000.
I'm going to give it a shot with Windows Vista. I have latest iTunes on laptop and my old 60g Photo connects just fine.
Best of luck to us all!

80 Gb ipod classic causes itunes 8.02 to freeze during sync

Itunes 8.02 w/ 80Gb Ipod classic. Owned and synced to same mac for a year. No hardware changed.
Initial problem occurred over a week ago when connecting ipod to mac. Error popped up and told me I would have to restore ipod to factory settings. Clicked on restore. ipod rebooted and cleared itself.
Since then I have trouble syncing completely. Ipod and itunes seemed to be syncing properly but slowly and then stopped with progress bar still-came back over an hour later, and progress bar still at same place and sync icon on itunes and ipod still spinning. Tried to cancel, change settings, and/or do anything in itunes and it freezes with spinning cursor. Will not force-quit. I have to manually reset or unplug ipod from connector to resume.
I have been able to load music (9.96Gb) onto ipod by disabling auto-sync, syncing of podcasts(over 300), 1 audiobook, and 1 .pls file-radio station (which never tried to synced to ipod before). All of these items I have had long before the problem. I loaded a new cd into itunes and created a new playlist. Itunes accepted this with no problem. Ipod will not sync the new music when I manually click sync.
*if thread already exists please send link-tried problem solving using other posts, but to no luck
Thanks

I found someone online who has the same problem, and claims that it can be fixed by reformatting the ipod in windows. I currently have not yet tried this, but I have tried reformatting it through disk utility on my mac pro, but to no avail.
I am planning on trying to reformat it through windows, and I will let you know what the outcome is when I get around to it.
Here is the link I found http://www.answerbag.com/q_view/550903
I hope that this may be useful to all the other people with this problem.

I have an iPod Classic 160GB and now it will not sync. I have restored to factory settings multiple times. It freezes during sync, gives -50 error code and says video is not supported on iPod. Please help.

I recently bought some songs from itunes, and I tried to sync my mac air laptop to my nano ipod, but it didn't work. I usually use my PC computer to do this, and my music is in the itunes library on my mac, it just won't sync to my ipod. Any ideas?Thanks!

All of my playlists made on my Ipod touch 3rd gen keep disappearing when I sync it to itunes. Drivng me crazy. All software up to date on both itunes and Ipod. Help please.

I tend to make my playlists right on my ipod. This did not happen for the last 2 years. Just started recently. Did get a new computer recently.

That is because you got a new computer. You can only sync all media from one syncing computer. You can sync from any computer to iPod using the manual method but that does not sync from iPod to computer.
