Suddenly, after a period of normal working, our client’s iPod refuses to sync and reports Error -48. What is it? Why does it happen? How can you fix it?
I’m not aware of any official list of what various odd iPod / iTunes error messages actually mean. In this instance I think what your little device is trying to tell you is that it has found some corruption on the iPod hard drive. Looking at suggested fixes for the problem the hard drive seems to be the culprit.
In cases such as this my first suggestion would be to reset your iPod to factory settings. If you’ve never done this before it sounds drastic but really it’s straightforward. Just connect your iPod, then when iTunes recognises the unit from the main iPod management screen in iTunes select the option to restore to factory settings. This will take a few minutes and a couple of do-yo-really-want-to boxes and then the iPod will be wiped and a new operating system installed. Some more waiting and the flash memory will be refreshed and away you go. The final step should be an automatic re-sync of music, photos, contacts etc. It may take an hour but when done you should be back to a functioning iPod, problem solved.
Looking at other iPod users experiences (and these are mainly Windows rather than Apple Mac OS X) you can go a long way by using My Computer to locate the iPod and right clicking, then running the standard disc check facility. Many people have reported that this works for them and may be quicker than a full restore as it leaves the music etc on the iPod.
Personally the restore route is more attractive to me as it stays within the iPod / iTunes family, and that is developed by the people responsible for your portable music package.
What happens if the fault repeats? If this were my iPod and it was still within warranty I’d be inclined to lob the unit back to Apple. They’ll send you a new unit as a replacement and it might just be that your original iPod was the one bad apple in that days barrel.
