Bad blocks are areas of media that cannot store data reliably. All hard disks have a few bad blocks when they are created, but these are "mapped-out" by the manufacturer when the drive is formatted. Mapping out bad blocks prevents data from being written to these defective areas of the media. Occasionally a good block will go bad. If this occurs and a file resides on that block, the file may be damaged.

The Apple Mac Mini originally launched in as a compact desktop computer measuring just mm square and 51 mm deep, until the redesign which made it more powerful and changed the dimensions to just 36 mm deep and mm square. It has proved popular with many users not as a primary home computer, but for a dedicated task, such as serving as a home theatre system, and most models include a built-in optical drive to play CDs and DVDs.
Accessing the inner workings of an Apple Mac Mini hasn't always been easy, and early models had to be pried open using a knife or even a pizza cutter; for obvious reasons, this has made repairs and upgrades awkward to carry out at home. More recent models of the Apple Mac Mini lack the integrated optical drive, instead opting for more hard disk space, and this means that if you have an older Mac Mini as your DVD player, you'll likely want to repair rather than replace it. At The Bookyard we understand the sense of attachment many people have to their Apple Mac, whatever model it may be, and will always aim to diagnose the problem so that it can be repaired with appropriate spare parts if it is possible to do so.
