: Rains bring in humidity that can be catastrophic to electronic and magnetic storage. To protect the hard drive and storage media from corrosion, ensure that the computer is kept in moisture free environment. Good air-conditioning helps but be cautioned, sometimes air-conditioners malfunction when humidity is high and water accumulates on the AC units.
Prevent power fluctuation
: Rain and heavy thunderstorm result in frequent power fluctuation, causing abrupt system shut down, hence increased chances of hardware/operating system crash, and data loss. To prevent data loss due to interrupted power supply use UPS. Also, using voltage stabilisers helps prevent power surge and fluctuation.
Don't store media at low-lying area
: Do not store data in low lying areas. A low lying area lacks proper ventilation and accumulates heavy vapours and smokes, causing corrosion in the storage media. There is also risk of sudden water inflow and flooding, which permanently damages the storage and data. Store computers and storage at least 5 feet above ground level to prevent damage from vapour accumulation, sudden water inflow, and flooding.
Track hard-disk health
: About 60% of all hard drive failure takes place due to mechanical failure, a result of gradual degradation of the storage surface and mechanical wear. Monitoring S.M.A.R.T. status, updates about major hard disk parameters such as drive temperature, disk performance, faulty sectors, distance between the heads and the disk platters.
