Occasionally, one or more sectors on an otherwise good hard drive will go bad. When this happens, the data in those sectors may be lost, but the data on the rest of the disk will be unaffected and the disk is still completely usable. Those bad sectors cannot be repaired, but they can be marked …
Integrated Drive Electronics or (IDE) are a type of hard drive controller which bundles the components of the hard drive and its controller into one interface. This allows for much simpler installation of the hard drive into the system by removing the difficulties associated with the separation of the components and controllers such as the predecessor …
Inkjet printers are cheap but they are still expensive enough to make some repairs worthwhile. There is a surprising number of parts in them, and every part is a potential failure point. The most common failure is a clogged print head. They are notoriously difficult to clean because of their microscopic nozzles. The first attempt …
