In Nigeria, the influence of Information and communication technology (ICT) has become very pervasive in everyday life. Every computer system used in the country has at least one hard disk for reasonable installation of both system and application software. We have investigated the average life span of hard disks by type and the causes of their crash. Data were collected from log book of University of Calabar Computer Centre between 1992 and 2007 (15 years). ANOVA model of two main factors with interaction was used to analyze the data. It was found that at 0.05 level of significance, Seagate hard disks last longer than the rest. The results further showed that the worst enemies of hard disks are erratic power supply and heat.
