When I connect one of my many iOS devices to a computer for synchronization purposes, I have iTunes running. In the iTunes left-hand area, I see an eject button to the right of the device's name. I always use "eject" after a successful sync, before unplugging the device cable. I'm presuming this is meant to be similar to Windows' "USB Device Safe Removal" feature (though iOS devices don't appear to show up there?) .. or when I choose "Eject" from the context menu of a USB-connected disk on my Mac's desktop.
Yet, sometimes I'm connecting my iOS device to a computer without having iTunes running. For instance, when using the device for USB-based "Personal Hotspot" connections, I don't need iTunes running. My questions are:
Is there a need to safely indicate removal of an iOS device from a computer, prior to removing the device cable?
If yes, must I fire up iTunes simply to access the "eject" button, or is there another easily accessible mechanism available?
I use both PCs and Macs so answers covering the two are appreciated. Good answers will also provide definitive supporting references. Thanks!
