An enclosure which is used to house a hard disk externally, adding storage and flexibility to any system is called Hard drive. The Computer is connected by the enclosure through a universal serial bus (USB) or Fire wire port, making it a plug-and-play device. When the system is up and running it can be turned Off and On. Providing portability between desktop and laptop, or home and office and also a hard drive enclosure can be used for many purposes. As carrying signal between different connector types is a trivial conversion. To require a separate embedded system to retransmit data over connector and signal of a different standard is so complicated in others. All built around disk enclosures includes factory assembled external hard disk drives, external DVD-ROM drives and others. External hard drive enclosure's main advantage is security. Hacking, Spyware, Viruses, Poorly written software, Trojan horses and hateful script is the major concern for online threats. The following are external enclosures that can turn an internal IDE hard drive into an external one. Hard drives are sold separately or as options. External Enclosures are the best way to get an External USB 2.0 or IEEE1394 (Fire wire) Hard Drive. A drive and enclosure together typically cost much less than a pre-made external hard drive! Installing financial data or sensitive programs on an external hard drive is one way to help ensure they stay safe. The hard drive enclosure can be left off when the user isn't accessing the programs or data, and when online. If several family members share the computer, an external drive is one way to keep key information or software private. For storing system back ups or Ghost images of the main hard disk an external hard drive is the perfect one. If the main drive fails, the ghost image on the external drive can re-create the main disk in mere minutes. Alternately, popular software like Acronis True Image will make a bootable carbon copy of the main disk on the external disk. In this case, the external disk can be removed from the enclosure and installed into the system for an instant fix. It is also possible to boot directly from the hard drive enclosure by using settings in the motherboard's Basic Input/Output System (BIOS) menu.
