I realize that this thread hasn't been active for a while, but I'm desperate. I got a refurbished iPod classic 120gb and a couple of months ago, all of a sudden it would not play any songs when it was connected to any device (at the time that the iPod stopped working it was plugged into my car's "media" player) or headphones. It just kept skipping to the next song but would not play. The songs play fine in iTunes. I tried to restore the iPod but when I connect the iPod and open iTunes i get "iTunes has detected an iPod in recovery mode. You must restore this iPod before it can be used with iTunes." I hit the OK button, click "restore iPod," another window pops up and says "iTunes has detected an iPod in recovery mode. You must restore this iPod before it can be used with iTunes." I click "Restore" and immediately get another window that says "The iPod could not be restored. An unknown error occurred 1434)." I have tried to do all of the steps listed and used different cords, but so far nothing has worked. I have a 2013 MacBook Air, and I've done the Disk Utility/First Aid and the only thing it says when I run the First Aid is that it was completed. I have also tried erasing the iPod from this section too but I just keep getting error messages that say "Unable to write to the last block of the device" and that the operation failed. When I try the Restore option from the Disk Utility it immediately pops up with a red stop sign and says "Validating target..., Validating source..., The volume on device "/dev/disk0" is not of type Apple_HFS or Apple_UFS, Could not validate source - Device not configured, Operation failed…" And when I go to check the diagnostics, sometimes I get a "ERROR Diag Halt" message, and other times the only specs I can get from it are Temp: current 32c, min 0c, and max 0c. I don't even see any stats for Retracts, Reallocs, Pending Sector, PowerOn Hours, Start/Stops. I have no idea what else to do or if the iPod is still salvageable. Any help r insight is greatly appreciated. Thanks!
