ITunes Could Not Synch

I have been having this synch error pop up while updating apps. etc. Although it appears that it actually is connecting and synching. This is more of a nusance than anything and I was wondering if anyone else has encountered the same problem since all the new updates came out and the new iOS?

I am having the exact same issue

ITunes could not synch calendars to iPhone because the iPhone disconnected

Started getting an error message during iPhone synch about two weeks ago: "iTunes could not synch calendars to iPhone because the iPhone disconnected"
- Am synching to my Outlook calendar on a system running Windows 7
- Everything else (contacts, podcasts, audiobooks, etc.) synchs just fine
- Tried totally resetting the iPhone and restoring the firmware
- Tried deleting the backups, preferences and resetting synch history
- Tried forcing a rewrite/replacement of the calendar database using iTunes
Nothing sems to work...still get the same message about not synching the calendar due to the iPhone disconnecting, but of course, it really hasn't disconnected since I can get it to immediately synch anything else.
Any ideas out there? Thanks...

Thanks midwestcraft. I had this problem and your answer solved it for me.
Thought this further info may be of use to some who wants more historic dates in their calendar.
I had "do not sync events older than" unchecked and the input field set to "0". When I changed it to 180, it worked perfectly. I've found that I can increase this number to "545" - anything higher causes the error. This seems to coincide with some strange multiple-entry events in my calendar.
Don't know if this will be a clue for somebody to fix the issue.

ITunes could not sync contacts because the synch server failed to synch....

I have a laptop running Windows 7 (professional edition) 64 bit using Outlook 2010 and I get this same daggone message every time I try to synch contacts, calender, or notes (all Outlook 2010)...."iTunes could not synch contacts to the iPhone because the synch server failed to sync the iPhone."
I called Apple's tech "support" and they said unapologetically that iTunes doesn't work with Outlook 2010. ***!?! And further that the solution was to use Outlook 2003 or 2007. And gave NO indication that any solution was in the works.
QUESTION: Does anyone have a SANE solution that doesn't require a degree in Star Trek to implement to this exact problem? I know the problem is widespread so please only respond if you are having the exact same problem. Otherwise the variable make the feedback meaningless. Thanks in advance!!!

ITunes Synch: 'x' items could not synch. See iTunes

I'm baffled. I get the msg when I synch my iphone with my MAC that reads on my iPhone: "iTunes Synch: 'x' items could not synch. See iTunes for more info."
I look in iTunes to see where that info may be, but am unable to find the info. I use 'x' to indicate a random number because the number is almost never the same. SO what am I looking for or how do I find this supposed info?

As far as I can tell, if you go to iTunes, right click your device in the lefthand panel, and click "Reset Warnings." That's what it took on mine to list the items that didn't copy to the phone. Hope that helps. =/

ITunes could not copy "Beethoven's Symphony No 9 (from "A Clockwork Orange")" to iPhone "Heywood Floyd's iPhone" because the file could not be read or written

Hello, i am having the following problem...
"iTunes could not copy "Beethoven's Symphony No 9 (from "A Clockwork Orange")" to iPhone "Heywood Floyd's iPhone" because the file could not be read or written" [ ... and yes, Heywood Floyd is an avatar name..]
With this...
a. it occurs when I try to synch my iphone with iTunes.
b. I have tested the "Beethoven's Symphony No 9" files that I have found on my iTunes, and my iPhone, as there is a copy of "Beethoven_ Symphony No. 9, _Choral_" folder that is the concert from Bernard Haitink & London Symphony Orchestra;
c. This is where is get weird, a sort of Jack Torrance moment, they only file related to "A clock work orange" is 06 A Clockwork Orange - Ode to Joy.m4p...
So what is happening, and how can I resolve this, as I am not able to synch between my mac and my iPhone....

Check the media source drive for errors.
See also Repair security permissions for iTunes for Windows. Not sure it is relevant but can't hurt.
If iTunes is confused about what media is and is not on the device take these steps:
Backup the device.
Restore as a new device.
Restore from the earlier backup.

"iTunes could not backup iPad because session could not be started w/iPad"

I was in the process of backing up my iPad this evening and it was, by the bar graph progress indicator, about 95% done but was taking FOREVER to get through that last bit. Then the power went out.
Now when I plug in the iPad and run iTunes, the synch goes ultra quick and then I get an error message saying: "iTunes could not backup the iPad because a session could not be started with the iPad".
Per one suggestion I found in some user discussion groups, I went into the iTunes preferences and deleted the backups it showed for my iPad. I drilled down into the folder where the backups are usually stored and those backups were now gone.
Unfortunately, that didn't cure the problem.
Nothing I do seems to work. Anyone care to give me some things to try? This is really frustrating. As it stands I have NO backup and I have some data on the iPad (like in writing apps, journal, etc.) I dare not lose, so I'm hesitant to do anything like a hard reset.

FIXED IT!
Before I got to my fix, here are the things I tried, none of which seemed to resolve the issue or improve the situation:
*Checked cables and connections
*Restarted iTunes
*Restarted my PC
*Checked to make sure PC date/time/time zone were all accurate
*Checked to make sure my security software (MS Security Essentials and Windows FIrewall) were up-to-date and no conflicts
*Made sure I had proper permission for the iPad backup folders. To ensure that, I selected the folders and clicked on "Take Ownership" in the context menu.
*I made sure that my user account is an Administrator account on this PC
*I logged out of my primary user account and logged in as the Computer Administrator (basically, a different user acccount that is an Administrator) and tried to do the backup to iTunes from there.
Failing with all of those things, many of which are suggested from the Apple knowledge base, I was just about to backup my iPad onto another machine, then transfer the backup to this PC and restore the iPad from here using that file, maybe even removing and re-installing iTunes, etc. Everything so far short of wiping the iPad and starting over from scratch, which I feared might end up happening.
Then, a lightbulb went off in my head. Why not do a reset on the iPad itself? Not the usual soft reset but the kind of reset that restores function to an iDevice when it isn't responding: press and hold both the Power and Home buttons at the same time and hold them until the device restarts, ignoring the "slide to turn off" prompt. After it finished booting up, I connected it with my PC, which brought up iTunes automatically, then...lo and behold, instead of seeing the rapid synch then error, it went right into backup. Took about fifteen minutes but it finished the backup without a hitch and synched the iPad.
So there you have it: one more thing to try. Maybe the FIRST thing you should try? It was so simple! I wish I'd figured that out BEFORE I did all that other stuff I mentioned above!
I'd like to read comments from anyone who has also experienced this problem and has tried my "fix" suggestion.

ITunes could not copy "Song Name" to the iPhone because an unknown error occurred (-50)

Recently when I tried syching one of my playlists into my iPhone 4 (Running on 5.1) using iTunes 11.2.0.26 for Windows (Windows XP SP3), I have been having a problem with some songs I acquired recently. It will sync all the other songs, but when it reaches the song in question, the following error message pops up:
"iTunes could not copy "Name of Song" to the iPhone because an unknown error occurred (-50)"
After which, it stops synching songs altogether.
I tried TWO different USB connectors (BOTH from Apple), and the error still occurs. When I remove the song in question, ALL songs sync normally.
I used the 'Get Info' option to see if there was something in the way the song was coded. This info is from one of the songs that gets synched normally:
Kind:                  MPEG Audio file

THIS is the info on the problematic song:

By the way, BOTH song (The ones synching normally, and this unsynching song), where purchased and downloaded from Amazon.com.
ANY information that will help me solved this problem will be VERY appreciated. Likewise, if you need any additional information, please let me know...
Thanks for your time.

My itunes could not backup bacause session could not be started

my itunes could not backup bacause session could not be started

I uninstalled iTunes 10.7 and re-installed it (after trying a lot of the other things Apple recommends with no success). That seems to have backed up my iPhone OK, and iPad is chugging along now. Hmm, got an popup error message about session, although it seems to be "transferring my purchases." And completed without displaying an error indication, just the battery state indicator.
Tried again. "iTunes could not sync information to the iPad ... because a connection could not be established to the iPad. (Which is sitting there unlocked with a wired connection and happily talking to iTunes otherwise.)
Tried again. Deleted some apps in iTunes not on iPad that had updates available, downloaded the updates to the remaining one. Sync worked. So maybe the problem is around apps updated on iPad and NOT updated in the PC Apps collection, or something like that. Programmer expected updates to be downloaded into iTunes then to iPad perhaps?
I'm leaving the WiFi synch turned off and trying wired only, to see if that helps (per some of the other online speculation re iTunes not getting app info from iPad nor session to iPhone).
BTW, the only relevant changes on my PC in several months were Windows security updates (and Norton signatures in background).

Itunes could not sync calenders to the iphone because the sync server failed to sync the iphone. Why not??

This is the message I get when trying to sync.
"itunes could not sync calenders to the iphone because the sync server failed to sync with the iphone."
WHY NOT?

I'm having exactly the same probs with iphone and ipad, synching to Outlook.
Both used to work fine, and now getting the same message, with conflicts in Contacts and Calendar - it's sending me round the bend.
Did you ever get an answer from anybody - don't seem to be able to find one, even though clearly we're not alone with the problem!?

ITunes could not copy [song title] because an unknown error occurred (-54)

For the past month or so I've been unable to sync it with iTunes. When I do, it starts but after a few hundred songs, I get the error that "itunes could not copy [song title] because an unknown error occurred (-54). When I click OK, it then says "synching" but nothing is actually happening, and the only way to even get my browser working again is to restart my pc. I have deleted the song in question, but it will just do it again with a different song. I have uninstalled and reinstalled iTunes to the most recent version, reset the iPod Touch numerous times, As well as deleting the iTunes files off of my computer and reloading all the muisc to it. To make things more interesting, it does all of this on my laptop pc as well as my desktop. Now. all of this may have started before upgrading the software, but that was the last time in months that I tried to sync it, so there may or not be a correlatoin there.
Any help is greatly appreciated, and thanks in advance.

Zelemiah,
I had the same frustrating problem and found that the way it worked for me was to SYNC the Phone in iTunes first with the SYNC Button on the bottom right of the Summary page at the end of the coloured Data used bar and then do the Version Update it worked first time for me and it appears that the 2.1 Update will not take unless the iPhone is synched with iTunes first as there may be too many differences which is why it keeps bombing...Hope it Works.

Itunes could not sync contacts to the iphone

I have just moved my iPhone 3G to a new notebook Windows 7 Outlook 2010. Can't synch my contacts through iTunes from Outlook (8149 of them), receive error = itunes could not sync contacts to the iphone because an error occurred remapping record identifiers. Everything else syncs fine. All used to sync under XP Pro Outlook 2003. I see many posts and have tried almost all of the solutions offered. Apple please help us get back to being productive, not troubleshooting our devices. Any advice from others is MUCH appreciated. Thanks in advance.

Restored iPhone; reset sync, cleared the sync option for contacts, confirmed removal of all records on iPhone, disconnected and closed iTunes - tried this many times; restored all library files from old computer, cleared ALL records, reset sync, disconnected and closed iTunes, then synced again; tried process again after de-selecting option for calendars, email, notes, etc. as well as contacts; placed a single contact record on the iPhone, then tried syncing, next de-selected the option to sync contacts, accepted the removal of that (all) contacrt records from the iPhone, again set up iTunes to replace all contacts on iPhone. Everything syncs fine execpt for my contacts. I have been trying everything I can think of... about 16 hrs into it so far.
