Common sense! it's essential too



As long as you know what your doing with different files, what your adding and more importantly what your deleting you shouldn't find yourself in a situation where you've broken everything and lost all your work



I reformat to keep things fast and tidy but I still have files from more than 4 years ago and I I dnormal backups. If I do reformat I plan out what I need to do, what I need to keep and store them in a safe place (usually another HDD) till I'm ready to put them back onto the HDD.



I'm not sure what the chances are of a freak accident, fire or theft but id say most the time people will have problems caused by something they have done
