Hard disk failures

Just like your bicycle or any 2 wheeler or 4 wheeler, the hard disk is also (electro) mechanical equipment used for storing data for future use. Many of your pcs other spare parts like the screen or mouse are purely electronic components and can only be affected by electronic means (such as a electricity blackouts). But, hard disk drives are affected by both electronic/electrical interferences and mechanical stress factors, which can easily create hard disk problems and hence valuable data loss.
