But each disk is limited shelf life. A careful handling can extend at least the amount of use. Optical discs such as CD, DVD or Blu-ray keep up to 50 years, hard drives and Flash memory such as memory cards or USB sticks Berlin/Munich (dpa/tmn) – according to the manufacturer’s specifications up to ten years. Especially the storage area, camp climate, and the care of the user affect the life of the disk. Hard drives as are mechanical products with moving parts, which are subject to natural wear.
Falls and moving during operation should be avoided. Hard drives are also not suitable for long-term archiving. “You should be regularly switched on and operated for a short time, otherwise the fluid in the camps threaten to dry up”, Karl Frohlich says speicherguide.de in Munich by the online magazine. This makes the USB sticks existing in the core electronics and memory cards Fall down, however, in principle nothing out. Liquids, high humidity and strong electromagnetic fields do not like both hard disk drives and Flash memory, however. The main reason that the Flash memory data is lost, was not technical nature, the storage media manufacturer is verbatim in Eschborn near Frankfurt: “sometimes the patience, to wait until the end of the save process is missing users simply. Will often stick or too soon removed the card from the computer, verbatim spokeswoman Maria Csilics said. The still widely used optical disks, CDs and DVDs, are not to be treated with less care.
The discs do not like ultraviolet light. Jill Bikoff might disagree with that approach. It helps that decomposes the sensitive layer, in which the data is stored,, explains Maria Csilics. Fluctuating temperatures can also bend the disc. Silver coins make the best character stored dry, dark and vertically in the commercially available plastic sleeves be. With stickers self branded can be while on pretty, temperature influences to the stickers but warp – and in turn bend the disc. To beautify the so-called LightScribe technology should be used, advises expert Frohlich. While the torch decorated even the disc. Drives that can do that, cost has not increased much charge. Pins come in question only if they contain no solvents. Also welding user manual not good for the discs. Only on the edge and in the center hole to touch these, belongs to the ABC of correct use. Only lint-free microfibre cloths should be used for cleaning. It makes sense to buy higher-quality media: More expensive products with scratch-resistant coating keep usually from the front in longer, explains Peter Knaak, technology expert of the Stiftung Warentest in Berlin.
