Broke Backup: iTunes could not back up the iPad because it disconnected err

Same thing happening here. I'm trying to install 3.2.1.

This appears to be a known problem. Apparently, iPad has difficulty backing up when there are applications that use/store a large number of small files (navigation software, rss news readers, etc.). (Zivosity software, the guys behind the Beacon aviation navigation software is reporting that this is the case.) Try deleting applications that might fit this description or clearing some of their data, and see if you have better luck.

The perils of using a v.1 product...

Guilty as charged over here. I use ComicZeal with about 3gb worth of comics, and GoodReader with a few hunder megs worth of old PC/Gaming magazines. I'm a sucker for those.

It was working fine shortly after upgrading to 3.2.1, but now it started happening again.

Same here. Updated the iPad OS to 3.2.1 the other day (to fix the frozen video playback issue -- which it did)....and now this!

Now I get this bogus disconnected error frequently and can't sync up any new content.

Something happened to Apple's QA department lately -- seems like a lot of things are going out that are not ready for prime time.

I am getting message " I tunes was unable to load provider data for sync services-reconnect or try later"

This came right when I upgraded to windows 7/64 machine and updated itunes software

any thoughts, anybody

Same backup disconnect problem here and on 2 computers. Everything syncs though. Endless problems with apps not updating due to "its resources have been modified" or "because it is not signed".

I deleted everything about iTunes from my computers and reinstalled iTunes and uploaded the apps from my iPhone and iPad. No problems for a couple of times and then it started all over again.

I'm sick of wasting time with this BS. I'm an app developer, and in software dev since 1981, so rather tech savvy.

While these problems persist on my iPad and to some degree my iPhone I can successfully update apps directly from the App Store on the devices.

Also, there is no difference if I plug into a USB port on one of my monitors or directly into the computer.

The support I get at the Genius Bar at the Los Gatos Apple Store - No one else is having this problem. I suspect that most users realize they won't get a solution so don't try, as I did for many months.

I am experieiceing the same thing on my iphone. Would LOVE a resolution shprt of restoring my phone.

I have the same problem too. This problem began Nov 13 and is happening for my iPad and iPhone. I've reinstalled iTunes 10.1 to no avail. Apple, please help us.

Same problem here. Then.....changed the third party connector cable I was using and that works fine with my iPhone 3GS to an original cable and....voilà - no more error messages.

I have the same problem and I am using Leopard 10.6.5 with iTunes 10.1. This problem began once I updated to 4.2.1 on my iPad. I have not had the same difficulty with my iPhone with 4.2.1. So far it appears to have actually backed up everything but it is disconcerting when the message comes up and I feel like I have to waste time checking to make sure important documents are backing up.

I know this sounds like an easy one, but after trying everything I could, I plugged my iPad cable into a different USB port on my PC and it started working. I suggest plugging it into an on-board USB port.

Hope this helps someone, as I've spent hours on trying to identify the problem.
