From a technological viewpoint memory cards are a fantastic addition to the way in which data can be stored and moved around but problems can occur with these devices in a variety of similar ways to hard drives. With this in mind it is worth remembering that within a memory card there are a lot of components that can be easily damaged if the device is dropped, bent or submerged in liquid. Likewise the device can also be prone to electronic failings if it is exposed to too much heat, cold or electricity.
