When an iPod is configured to synchronize with a Mac computer, the Mac formats the hard drive or flash memory in the iPod using the HFS file system. This file system is incompatible with Windows, making a Mac-formatted iPod unusable on a Windows-based PC. If you have a Mac-formatted iPod you want to sync with a Windows PC, you can use iTunes to return the iPod to its original factory state and format the internal storage for use with Windows.
