I'd like to use my iPod touch as an external hard drive but I can't find the "enable disk use" option anywhere in Preferences, or in the device summary. Instead the options in the device summary are: 1. Open iTunes when this device is connected 2. Sync only ticked songs and videos 3. Prefer standard definition videos 4. Convert higher bit rate songs to 128 kbps AAC 5. Manually manage music and videos 6. Encrypt iPod backup There is also a button saying "Configure Universal Access" under all that.
