I have an ipod classic with 20 gig. When I attempt to restore it it to original settings I get unknown error 1439. What can I do to get it to work again?

See if this helps: http://support.apple.com/kb/TS1372

1. Disconnect and reconnect your iPod to iTunes, and then attempt to restore or update the iPod again.
2. Restart your computer and then attempt to restore or update the iPod again.
3. Try connecting your iPod to a different USB port, and then attempt to restore or update the iPod again. Connecting to a USB 2.0 port is recommended. For Windows computers, refer to Identifying USB 2.0 ports on your computer for instructions.
4. Remove any USB devices not manufactured by Apple that you have connected to your computer (it is not necessary to remove your keyboard or mouse). Then, attempt to restore or update the iPod again.
5. Update to the latest version of iTunes, and then attempt to restore or update the iPod again.
6. Try to restore or update the iPod again using a different user account for your computer. For example, create a new test user account on the computer with admin rights, and with iTunes installed, try to restore/update the iPod.
7. Try disabling Disk Use on your iPod and attempt to restore or update the iPod again. If that doesn't work, try enabling Disk Use on your iPod and attempt to restore/update. Refer to Putting iPod into Disk Mode below for instructions.*
8. If using a Windows PC to restore or update your iPod, try to reregister ".dll" files as described below this list.**
9. If using a Windows PC, try to update or reinstall your Windows USB drivers, referring to the section titled "iPod only: Updating, or in some cases reinstalling, the drivers for your computer's USB interface may resolve this issue."

Hi, now, when you restored your 80 gB classic, did you upgrade the firmware to 1.1.2?
If so, do not.
I refuse as my firmware 1.1.1 works the ipod great and the only trouble started (twice) on trying to update the firmware.
Try a hard factory reset:support.apple.com/kb/HT1339

Then, charge fully with AC charger (this was recommended to me twice in an Apple store)

After wards, use USB to connect to your computer and do not allow it to upgrade to 1.1.2

(See incidental article about ipod touch: rupertgee.wordpress.com/2007/12/02/downgraderestore-ipod-touch-firmware-to-version-111-using-os-x/ this might even work on ipod classic - you've got nothing to loose); also have a look at Apple's updates: apple.com/support/downloads/

This seemed to work for me:

1. Download latest version of iTunes
2. disconnect from internet (I did this by removing my wireless adapter).
3. Put iPod into disk mode (hold select and play until display says "disk mode" at the top).
4. Connect iPod to computer
5. You should be prompted to restore, click yes.
6. Message will appear saying can't connect to internet, do you want to restore to latest version "2.0.1" instead? (Something along those lines).
7. It should start restoring and work this time.

Hope this helps.

send it back to apple.
your ipod has a bug sad to say.

1. Put the iPod on a flat surface to stabilize it.
2. Slide the Hold switch on, then slide it off
3. Hold down Select and Menu together for several seconds with two fingers.
