"The iPhone cannot be synced. The required disk cannot be found."

I have been having this problems since I got my iphone last year. Early on the phone would sync after 2-3 tries but as of the last 2-3 months I have been only able to sync it 2-3 times even after trying all the solutions presented by the troubleshooting and reading forum posts that seem to have a similar or near similar problem.

The first message I get after having the phone sync is
"The iPhone cannot be synced. The required disk cannot be found."
After itunes attempts to sync again I get a different message that says
"The iPhone cannot be synced. An error occurred while writing to the device."

Ive ran the diagnostic and this is what I got:

I had the same problem and fixed it.

"The iPhone cannot be synced. An error occurred while writing to the device."

I think it is caused by downloading too many apps, or large apps, and then when syncing over USB it doesn't recognise the iPhone and you get "The iPhone cannot be synced. An error occurred while writing to the device."

To fix this:

1. Ensure iTunes is closed & iPhone is disconnected but keep USB cable connected to iPhone
2. hold down CTRL + SHIFT on your keyboard
3. connect USB cable to PC and wait. If iTunes doesn't start for a minute then start it (keeping hold of CTRL + SHIFT)
4. if it wont let you start iTunes or all your icons are selected then release CTRL + SHIFT
5. when iTunes starts it may ask you about safe mode or something similar, say yes
6. Your iPhone should list as a device as normal, click sync.

It will then start the sync as normal and you may find it will transfer only one or two apps and you may get the dreaded error message again as I did. However, persist with the above steps and eventually it sync'd all my apps with no error message. Because I have only just done this I haven't downloaded any more apps so it might be a frequent thing but better than the error message.

I've found out why this happens

1: The Cord you are using to connect the phone is messed up, borrow another one to test or buy a new one.

2: for some reason you have a faulty USB port. It may work with other items (HDD's, printers etc) but you will get the error when trying to use iTunes with that port. Choose another port.

3:Make sure your USB drivers are updated and see 2.

Hope this helps.

After several versions of iTunes and a year of not being able to Sync my iPhone with my x86 version of iTunes, I finally got it to fully sync. I have been attempting to sync via a USB cable through a fully loaded USB hub. I switched the cable from the hub to the USB port on the computer itself and it's finally syncing!!! I think the issue could be one of three things; 1) syncing through a hub (this one was powered), 2) syncing through a fully loaded hub, or 3) a sporadically faulty hub that mostly manifests itself through large data transfers.

I hope this helps!

I ended up getting assistance from Applecare. One of my problems was that I thought they were referring to a real disk, rather than a virtual disk (music). Also I had a new computer and the builder hadn't told me where the audible files were. Turned out they were stored in three different places in the old computer (the audible files decide this). So, my beloved iPhone now has OS4 and is behaving itself. Recommend Applecare. I think Apple need to give clearer instructions about this problem, not to mention the dreaded exclamation mark.

Looks like this can happen in multiple scenarios. For my what seems to have happened was the fact that I got a new computer and had not sync'ed up my phone with the old computer in a long time. When I connected my iPhone to the new computer, I was also prompted to upgrade to iOS 4.1. I did so, and my phone ended up with the default apps. When it started syncing, it tried to move the apps that were in the new hard drive into the phone and it failed.

To fix my issue, I synced back with the old computer and got all my apps back in the phone. Then I synced again with the new computer and, after Googling for a while, right clicked on the phone icon in the right column and chose to "Transfer purchases". They sync is happening right now and it seems to be chugging along.

Best luck to all of you...
