hummmm,

Just an observation, however, isn't that what Nihil had said:

Nihil: power spikes
You: like lightning

Nihil: Impact, whilst in use
You: improper handling of hdd like knocking of banging the hdd

Nihil: EMP from other equipment
You: magnetic field around the hdd

Nihil: Heat & lack of airflow around the HDD
You: heat problems
