To Solve iTunes Crashing Problem:
When the device was first given to me I formatted it using FAT32 filesystem (iTunes would crash and I would not be able to use the restore button). I reformatted it using gparted in ubuntu because Windows 7 would only let me use exFAT – this is no good.
After formatting the device it would no longer crash iTunes so I could then try to restore it using the correct iTunes restore button. Unfortunately, the restore would fail and the following error would be given: iPod could not be restored. An unknown error occurred 1439.
To Solve iPod restore error (iPod could not be restored – An unknown error occurred 1439.)
The next step which took me ages to figure out was to use a windows XP virtual machine to install an old version of iTunes. After iTunes was installed on the XP box I was able to restore the iPod as normal.
My main computer was running windows 7 64bit and iTunes 10. – This configuration would not restore the iPod and would always have the 1439 error.
The windows XP computer was running 32bit windows and iTunes 9.2.1.5 – this worked correctly and the iPod appears to be fixed.

Windows 7 only formats in exFAT which was driving me crazy because it caused this error. You can run a portable version of a FAT32 formatter such as ridgecrop’s fat32formatter utility.

Then iTunes will be able to restore… or it did in my case.
I used iTunes 12.5.4.42 64bit and it worked fine once the formatting was corrected.
