    Error -81
    Hello all,

    Having uploaded music onto itunes I attempted to sync my ipod classic (120GB), but after managing to sync some of the tracks (titles A-C), i receive the message: unknown error (-81)

    Can anyone help?

    Texas, where else?
    15" MBP '06 2.33 C2D 4GB 10.7; 13" MBA '11 1.8 i7 4GB 10.10; 21" iMac '13 2.9 i5 8GB 10.10; 5s & 5c
    error code -81 is "sector number never found on a track"

    I can only guess here what that means - whatever song iTunes is trying to sync next, the system is unable to locate it. Time for troubleshooting, to determine which song is causing the issue. Whether it's a faulty file, file written to a bad sector, ??, it's going to take someone a lot more knowledgeable than I am to answer.

    I'd try unchecking maybe 10 songs at the point where you think the sync is stopping, try again and attempt to narrow it down.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.
