Unable to Sync or Transfer Music
iPod Touch: 2nd Gen
OS Version: 4.0
Computer OS: Windows 7
Other info: My iPod library is manually managed.
Background info: Awhile ago I used to get an error (code 0xE8000065) every time I plugged in my iPod. My iPod would not appear in iTunes. I resolved this by enabling C-State in my bios.
Now, my iPod appears in iTunes, but every time I try to transfer music or apps from my library to my iPod I get one of several error messages:
[*] The application "X" was not installed on the iPod "X" because an unknown error occurred (0xE8004006).
[*] Attempting to copy to the disk "X" failed. An unknown error occurred (0xE8004006).
[*] The iPod "X" cannot by synced. An internal device error occurred.
[*] iTunes could not copy "X" to the iPod "X" because an unknown error occurred (0xE8004006).
[*] Attempting to copy to the disk "X" failed. A diplicate file name was specified.
[*] iTunes could not copy "X" to the iPod "X" because an unknown error occurred (-48).
[*] Attempting to copy to the disk "X" failed. There are too many files open currently.
[*] iTunes could not copy "X" to the iPod "X" because an unknown error occurred (0xE8004017).
[*] iTunes could not copy "X" to the iPod "X" because an unknown error occurred (-42).
I've tried reinstalling iTunes, resetting my iPod, restoring my iPod, restarting iTunes, using a different cable, and using a usb port in the back of the computer. I don't know what the problem could be. I'd really appreciate any help.
