Patent ID: 8265919

Claim:
A method comprising: transferring data from a human-portable data processing device to a data processing system, comprising: classifying, by the human-portable data processing device, incoming read commands according to a section of a file system in which the data requested by the incoming read commands would have been found were the file system used at the human-portable data processing device; generating, by the human-portable data processing device in response to the incoming read commands, emulation data that emulates data which would have been found in the section of the file system; and responding, by the human-portable data processing device, to the incoming read commands with responses that include the emulation data wherein responding to the incoming read commands comprises responding to a first incoming read command that specifies a first memory address from which responsive data is to be read with data read from an address in the storage medium and responding to a second incoming read command that specifies a second memory address from which responsive data is to be read with data read from the address in the storage medium, wherein the first memory address specified in the first incoming read command differs from the second memory address specified in the second incoming read command.
