Content control systems and methods

1. A control system comprising:

an interface configured to receive a content request and a request identifier from a request source wherein the content request identifies content stored on a storage medium;

a processing system coupled to the interface and configured to determine an encoding identifier used to encode the content on the storage medium, and process the request identifier and the encoding identifier to determine when the request source is a valid destination for the content, wherein the request source is a valid destination when the request identifier corresponds to the encoding identifier; and

the interface configured to transfer the content to the request source when the request source is a valid destination.

2. The control system of claim 1 , wherein the processing system is configured to generate a response to the content request and wherein the interface is configured to transfer the response.

3. The control system of claim 2 , wherein the response comprises an error message when the request source is not a valid destination for the content.

4. The control system of claim 2 , wherein the response comprises invalid data when the request source is not a valid destination for the content.

5. The control system of claim 1 , wherein the processing system withholds a response when the request source is not a valid destination for the content.

6. The control system of claim 1 , wherein the storage medium comprises a rotating storage medium.

7. The control system of claim 1 , wherein the storage medium comprises a semiconductor based storage medium.

8. The control system of claim 1 ,

wherein the interface is further configured to receive the content transferred by a content source; and

wherein the processing system is further configured to encode the content with the encoding identifier; and store the content encoded with the encoding identifier on the storage medium.

9. The control system of claim 1 , wherein the processing system is configured to generate an error correction code for the content using the encoding identifier as a seed and store the error correction code with the content on the storage medium.

10. The control system of claim 1 , wherein the encoding identifier is a seed of an error correction code stored with the content.

11. A method of operating a control system comprising:

receiving a content request and a request identifier from a request source wherein the content request identifies content stored on a storage medium;

determining an encoding identifier used to encode the content on the storage medium;

processing the request identifier and the encoding identifier to determine when the request source is a valid destination for the content, wherein the request source is a valid destination when the request identifier corresponds to the encoding identifier; and

transferring the content to the request source when the request source is a valid destination.

12. The method of claim 11 further comprising:

generating a response to the content request and transferring the response.

13. The method of claim 12 , wherein the response comprises an error message when the request source is not a valid destination for the content.

14. The method of claim 12 , wherein the response comprises invalid data when the request source is not a valid destination for the content.

15. The method of claim 11 further comprising:

withholding a response when the request source is not a valid destination for the content.

16. The method of claim 11 , wherein the storage medium comprises a rotating storage medium.

17. The method of claim 11 , wherein the storage medium comprises a semiconductor based storage medium.

18. The method of claim 11 ,

further comprising:

receiving the content transferred by a content source;

encoding the content with the encoding identifier; and storing the content encoded with the encoding identifier on the storage medium.

19. The method of claim 11 further comprising:

generating an error correction code for the content using the encoding identifier as a seed; and

storing the error correction code with the content on the storage medium.

20. The method of claim 11 , wherein the encoding identifier is a seed of an error correction code stored with the content.

21. A storage system comprising:

a storage medium configured to store content; and

a control system coupled to the storage medium and configured to receive a content request and a request identifier from a request source wherein the content request identifies the content stored on the storage medium, an encoding identifier used to encode the content on the storage medium, and process the request identifier and the encoding identifier to determine when the request source is a valid destination for the content, wherein the request source is a valid destination when the request identifier corresponds to the encoding identifier, and transfer the content to the request source when the request source is a valid destination.

22. A device comprising:

a host system; and

a storage system coupled to the host system and configured to receive a content request and a request identifier from a request source wherein the content request identifies content stored on a storage medium, determine an encoding identifier used to encode the content on the storage medium, and process the request identifier and the encoding identifier to determine when the request source is a valid destination for the content, wherein the request source is a valid destination when the request identifier corresponds to the encoding identifier, and transfer the content to the request source when the request source is a valid destination.

23. A device comprising:

a storage system having a storage medium; and

a host system coupled to the storage system and comprising a control system configured to receive a content request and a request identifier from a request source wherein the content request identifies content stored on the storage medium, determine an encoding identifier used to encode the content on the storage medium, and process the request identifier and the encoding identifier to determine when the request source is a valid destination for the content, wherein the request source is a valid destination when the request identifier corresponds to the encoding identifier, and transfer the content to the request source when the request source is a valid destination.
