I have a 2001 first gen iPod, and today I put in a new 40gb drive (MK4007GAL, pretty sure it's supported by the iPod). I tried to restore the iPod from iTunes but got error 1429. Then I used an ipsw file to restore the iPod, but got the same error. Then I tried erasing the hard drive in disk utility because I thought maybe it needed to be formatted, but the progress bar didn't budge when it was erasing. I don't think the drive is dead, because it's basically brand new. I also checked to see if the old hard drive worked, it did. Any suggestions?
