From a DriveSavers email blast:
DriveSavers just launched the first and only hard drive simulator for iPhone and iPod touch! Known as DriveSaver, the free hard drive simulator features a virtual environment that allows you to explore the inner workings of a common hard drive. It simulates various types of hard drive failures using ultra-realistic sounds and visuals and includes essential backup and data loss prevention tips.
DriveSaver is a fantastic demonstration tool to help illustrate hard drive data storage technology. It’s educational, it’s functional and it’s fun! It might even help you identify problems with a bad hard drive. Anyone who has ever wanted to see inside a hard drive or learn how drives work and why they fail, must try it!
It’s a pretty useful tool to show people what can - and very often does - happen. The app is free, and is in the App Store now.
