Imaging materials. Magnetic hard drives used for image storage. Care and handling1 Scope This International Standard concerns the storage, care, and handling of HDDs. It recommends handling procedures to maximise the effective life of the data written on magnetic HDDs. Faulty care and handling methods can cause damage to a disk and the contents written thereon. It also recommends storage practices to preserve both the hard diskmedia and the content encoded thereon. The recommendations in this International Standard apply where the
