Unable to update to 1.1.1 do I need to? Unknown error (1417)

Question

iPod Classic 80GB. My software version is 1.0.2. Every time I plug my iPod in I am informaed that a newer version of the software (1.1.1) is available, but every time I try to update I am told that the message "could not be completed. An unknown error has occurred (1417). However, I want to know if updating really makes any difference to the way the iPod runs?
I don't want to have to restore unless absolutely neccessary as it takes about a day and a half to resync all my music, which means leaving my computer (which is in my bedroom) on overnight.

Answer 1

You should refer to the link first, since it directly deals with your problem (error 1417). You should try each procedure. You never know what might fix it.
(ex. even though you think your USB drivers are up-to-date, you should double check and update them).
If the procedure outlined in the link doesn't work, you could try my procedure.
As for your question:
If you have the "Manually Manage Music" ticked in itunes, those are your ipod's settings no matter where you plug your ipod in. If you wish to update using another computer, you could install itunes in another computer, since your ipod is set on Manually Manage Music, it won't sync the new library. A window will likely open asking that your ipod is synced to another library, would you like to sync to this library? Click CANCEL. Then update your ipod.
Good Luck! And let us know how it went.
