Digital (electronic) data is stored in a variety of places: an organization’s servers, individual desktops backup tapes, employees’ home computers, PDA's, the list goes on… Electronic data may also exist in forms that are relatively inaccessible, such as deleted or fragmented data. Whether a particular potential source of electronic data should be reviewed for production will depend on the nature of the matter, the nature of the source, and the nature of the data that may reasonably be expected to be found.
