i read somware that it takes a magnet (nomal fridge magnet type) 20000years to lose its magnetisem. HDDs are made differantley than tapes so the magnetic particals should be more robust than that on a tape and should last much longer than a tape . so can a HDD be much more differant than a fridge magnet life span wize??? (magnetic lifespan of the data itself ,not the bearings or motor lifespan witch is obviousley less) (and of corse assuming it is not expozed to a magnetic feilds)
