Adaptec laptop hard drive enclosure

An enclosure is a term often associated with computer hard drives. However, it describes any external or internal box that holds a computer peripheral such as a hard drive. The picture shows an Adaptec laptop hard drive enclosure that could be used to connect a laptop hard drive to a desktop computer. These enclosures can be purchased online or at any local computer retail store.
