By default when you plug in a external hard drive via USB to a Windows XP computer auto play will automatically launch. This can be beneficial if you rarely plug in USB hard drives and when you do you like to decide what action to take such as copying pictures from the drive to the local computer or printing documents from the drive to a network printer. In most scenarios though you will probably be moving files to and from the external hard drive to your computer and the auto play pop up is annoying. It is even more annoying if you almost always have the external hard drive attached so every single time you reboot your Windows XP computer you have to deal with one more annoying pop up. Below is information on how to disable the automatic auto play pop up per USB hard drive.
If you have a jailbroken iPhone or iPod Touch you may come across custom applications that you would like to install via iTunes so all of your applications are still managed in one place. I originally thought that I would just be able to drag the applications directly into iTunes, sync my iPod Touch with iTunes, and begin using my new application. I believe this used to be the case before iPhone OS 3.0 was released which is the version of firmware installed on my Touch. Anyhow I attempted to proceed by following the below steps and ran into an error also noted below.
