What is a Hard Disk Enclosure and how do I use one?

Hard Drive
There are lots of external hard drive solutions on the market from fellowships like Maxtor, Freecom and Lacie but these solutions include the Hard Disk as well as the enclosure. Great if you just want to buy something off the shelf but, if you've got a hard disk that you have salvaged from an old Pc then its significantly cheaper to buy an Enclosure and use the Hard Drive you have to create your own solution. There is nothing intimidating about using a Hdd caddy, think of it as a tray that you slot the Hard Drive into (secured by a incorporate of screws) and with external connections that allow you to associate the enclosure to your Pc. They are uncomplicated to use, great for recovering data from old Hard Drives and exquisite for recycling old hard disks. There are a few options to think when considering a Hdd Enclosure:
1. Hard Drive Size (physical not storage capacity): Hard Disks come in two basic sizes depending on whether they are designed to be used in a Laptop of Desktop (Tower) Pc. A Laptop Hard Drive is described as a 2.5" whereas the drive from a Desktop Pc is 3.5".
2. Interface: Most new Hard Drives are now Sata (Serial-Ata) disks but if you are seeing to use a hard disk salvaged from an old Pc its probably going to have an Ide interface (also described as Ata or Pata). The Ide interface is pretty easy to distinguish as it has 2 rows of 22 Pins along the relationship interface. A Sata Disk will have to uncomplicated plastic seeing connectors
3. Connection Type: Usb & Firewire connections are the most base ways to associate a Hard Disk Case to your Pc or Mac some newer cases also have eSata as an option. Your option of relationship will often be dependant on the computer/devices you want to use your hard drive with and if you'rere not sure you can buy cases with multiple interface options but bear in mind these will cost more than say an enclosure that only connects via Usb.
4. Number of Bays: single and dual bay enclosures are available. A dual bay enclosure can take two Hdd's and some support Raid so both hard disks can be set up to appear as a single drive or support virtual back-up options over both Hard Drives. With any hard drive, whatever the protocol, you also need to think exactly what you are going to use it for, and think these four attributes.
