Sync throws error message -48 (unknown error)

Synch throws error message and then does not synch music.

I'm having this same problem. In my case the library file is on my main internal hard drive, but is partitioned to the e: logical drive. Permission should not be a problem.

Okay so my phone crashes approximately every 30 seconds. I have tried resetting it by DPU as well as on the phone itself. Once in awhile i get an error message about unknown error 1. If i look at the diagnosis or if runs on itunes i get the following. When I called the support at AT&T they think the phone is shot and it is a hardware thing but i have a hard time believing that when it happened when I sync'd it to my computer. It did get progressively worse though, at first it crashed not that often and then got worse. So restores are failing, recovery, everything. Anyone run into this?

Errors 3000-3999 (3004, 3013, 3014, 3018, 3164, 3194, and so on): Error codes in the 3000 range generally mean that iTunes cannot contact the update server (gs.apple.com) on ports 80 or 443.
Update to the latest version of iTunes.
Verify the computer's date and time are accurate.
Check that your security or firewall software is not interfering with ports 80 or 443, or with the server gs.apple.com.
Follow Troubleshooting security software. Often, uninstalling third-party security software will resolve these errors.

My Purchases show partially downloaded. When I attempt to resume the download I recieve an error message: "an unknown error occurred -50". I tunes has charged for the download and sent a reciept however the shows wont play?

I had the same problem so (assuming under the Purchased items in the Store you have a song stuck at 'Downloading'):
I went to Music, then Artists.
From there I chose the album.
The song that failed to download had the cloud symbol next to it.
I clicked the cloud symbol and the song completed the download for me.
(Please note this was in iTunes for Windows - I expect it to be similar in iTunes for Apple)

HT1386 unable to sync my ipad2 receive an error message 1140 (unknown error) HELP..don't want to have to go to the apple store to be able to sync my ipad to my desktop !!

For some unknown reason, I am unable to sync my ipad2 with my desktop. I receive a message saying it cannot sync due to an unknown error 1140.
Hate to have to run to the apple store to get this resolved...hope someone here knows the answer !! I need to sync !!
Thank You.

Experienced User Terrell Smith recently posted on this Error Code:
Terrell Smith:
"Today I was in an Apple Store, and four Apple Geniuses could not solve this problem. It seems to have something with large iPhoto Libraries, because when I started iPhoto up with a small library (1,100 photos), the problem did not occur. In iTunes, under the Photo's option "Sync Photos," if the iPhoto library is large (38,000 photos), the option to select the radio button "Selected albums, Events, and Faces" is grayed out, and you cannot select it.
My guess is that since the large iPhoto library will not fit on your iOS device, iTunes throws the 1140 error.
As others have noted, if you uncheck "Sync Photos" in iTunes, the rest of things will sync instead of throwing the 1140 error message.
But you don't have synced photos then.
The Apple Store told me they have no solution for this error. We should file iPhoto Feedback, and that this issue has been escalated to Apple Engineering."

Error message 'An unknown error occurred (-50)' It repeats this message when I plug my iPhone

When I open iTunes, I get the error message 'unknown error has occurred (-50)' It repeat this message when I plug my iPhone in and it will not let me sync!! Please help, I think this began after an update of iTunes, but it has not resolved after trying to revert to the earlier version.

Hi, Hoofin22.
Thank you for visiting Apple Support Communities.
Here are a couple articles that provide some helpful troubleshooting steps for error -50. Also make sure the most current version of iTunes is installed.
iTunes Store: "Error (-50)" when downloading purchased content
http://support.apple.com/kb/TS1583
iTunes: Specific update-and-restore error messages and advanced troubleshooting
http://support.apple.com/kb/TS3694
Error 13, 14, 35 and 50 (or -50)
These errors are typically resolved by performing one or more of the steps listed below:
Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different Dock Connector or Lightning Connector to USB cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. An incorrectly set default packet size can cause this error. Contact the software manufacturer that installed the packet-size modification for assistance. Or, follow this article by Microsoft to reset the packet size back to the default for Windows:How to reset Internet Protocol (TCP/IP).
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.
Hope that helps,

I downloaded an album from iTunes and some of the songs downloaded but others didn't there was an error message 8003 Unknown error occurred. While I downloaded the album to my phone, it wouldn't download to my mac, what am I doing wrong???

I purchased an album on ITunes store, while the items downloaded to my phone, it didn't download to my mac. Some of the songs downloaded but not the majority, when I try to download the songs, it gives me an error 8003 Unknown error occured. What am I doing wrong? If I can't download this album, how do I get a credit??

Hello mercdw,
Once the music has been downloaded to your iPhone, you can transfer purchases from your device to iTunes.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer
http://support.apple.com/kb/HT1848
Alternatively, the following article provides further information regarding this error and steps that can help resolve the issue.
"Error -50," "-5000," "8003," "8008," or "-42023"
These alerts occur due to timeouts or conflicts trying to write a file during download.
If you encounter this issue while accessing iTunes Store:
See iTunes 9: "One Moment Please" or "Error (-50)" message when accessing iTunes Store
If you encounter this issue while while downloading something from the iTunes Store:
Delete your iTunes Downloads folder, located in:
Mac OS X:  ~/Music/iTunes/iTunes Media/Downloads Note: "iTunes Media" may appear as "iTunes Music. Also, the tilde (~) refers to your Home directory.
Windows Vista:  \Users\username\Music\iTunes\iTunes Media\Downloads\
Windows 7:  \Users\username\My Music\iTunes\iTunes Media\Downloads\
Windows XP:  \Documents and Settings\username\My Documents\My Music\iTunes\iTunes Media\Downloads\
After locating your iTunes Downloads folder:
Quit iTunes.
Delete the Downloads folder on your computer.
Open iTunes.
Choose Store > Check for Available Downloads.
Enter your account name and password.
If you encounter this issue while while downloading Digital Copies using Windows:
Use MSCONFIG (directions for Windows XP and Windows Vista/Windows 7) to disable conflicting software.
If using MSCONFIG steps resolves the issue, you may want to use the System Configuration Utility to turn on the third-party System Services and Startup Items one at a time (restarting your computer after turning on the item or items) to identify which System Service or Startup Item is causing the conflict.
You can turn all of them back on by selecting the Normal Startup option under the General tab of the System Configuration Utility window, but please note that this may cause the issue to reoccur.
If you are able to isolate the issue to a particular third-party software, you may wish to contact them to let them know of the conflict.

Unable to log on with apple ID - error message "an unknown error has occurred"

When I try and log on to apple website using my apple ID, I get an error message saying "an unknown error has occurred". How can I fix this?
I've changed my password several times and was able to successfully make a purchase from Itunes using new password, so I'm not sure what the problem is.

For whatever reason, I can now log in to the apps store with one of my ids. It says my other account no longer exists so I can not update pages and numbers. It will not let me rebuy these programs under the working account because my computer recognizes that I bought them before.
