Abstract

A method for recovering data from corrupted flash media and regenerated damaged flash media have been disclosed. In one embodiment, the method comprises accessing data on a flash media, searching the data for file indicia corresponding at least one predetermined file type, reading the data based on information in the file indicia, the data including a recovered file, and storing the recovered file on a storage medium. Other embodiments have been claimed and described.

Claims

1. An apparatus comprising:

a housing means for housing at least a controller;

at least one flash media connector means for accepting at least one type of flash media;

storage means coupled to the controller;

means for detecting an activation event;

means for recovering data, in response to the activation event, the data corresponding to at least one application file from a corrupted flash media device coupled to the flash media connector means;

means for searching for file indicia corresponding at least one predetermined file type;

means for reading data based on information in the file indicia, said data comprising recovered data; and

means for storing the recovered data on the storage means.

2. The apparatus of claim 1, wherein the flash media connector means is to accept at least one type of flash media either directly or via a flash media connector adaptor.

3. The apparatus of claim 1, wherein the means for detecting an activation event is to recover the data by accessing the flash media at a low level to access raw flash data stored on the flash media device.

4. The apparatus of claim 1, wherein the means for searching for file indicia comprises searching raw flash data stored on the flash media device for the file indicia.

5. The apparatus of claim 1, wherein the means for reading data based on the file indicia, comprises reading data from raw flash data stored on the flash media device.

6. The apparatus of claim 1, wherein the flash media connector means comprises means for determining a type of media connected to the media connector means.

7. The apparatus of claim 6, wherein the means for determining a type of media connected to the media connector means comprises means for determining the type of media by reading one or more address pins on the media.

8. The apparatus of claim 1, further comprising control and transfer means for performing data transfers and handshake routines based on a type flash media detected to be connected to the flash media connector means.

9. The apparatus of claim 1, wherein the flash media comprises one of a CompactFlash compatible card, a SmartMedia compatible card, a MultiMediaCard compatible card, a Secure Digital compatible card, a Memory Stick compatible card, and a Universal Serial Bus (USB) Drive.

10. The apparatus of claim 1, wherein the activation event comprises detecting a flash media to be connected to the flash media connector means.

11. The apparatus of claim 1, wherein the activation event comprises a user activation of a button on the apparatus.

12. An apparatus comprising:

a flash media connector means for accepting at least one of a plurality of different flash media;

a means for reading and writing to a flash media coupled to the flash media connector means;

a means for recovering data from a corrupt flash media coupled to the flash media connector means, in response to detecting an activation event; and

a means for storing recovered data.

13. The apparatus of claim 12, wherein the flash media connector means is to accept at least one type of flash media either directly or via a flash media connector adaptor.

14. The apparatus of claim 12, wherein the means for recovering data comprises means for searching for file indicia corresponding to at least one predetermined file type, and reading data based on information in the file indicia.

15. The apparatus of claim 14, wherein the means for reading data based on the file indicia, comprises reading data from the raw flash data.

16. The apparatus of claim 12, wherein the flash media connector means comprises means for determining a type of media connected to the media connector means.

17. The apparatus of claim 16, wherein the means for determining a type of media connected to the media connector means comprises means for determining the type of media by reading one or more address pins on the media.

18. The apparatus of claim 12, further comprising control and transfer means for performing data transfers and handshake routines based on a type flash media detected to be connected to the flash media connector means.

19. The apparatus of claim 12, wherein the flash media comprises one of a CompactFlash compatible card, a SmartMedia compatible card, a MultiMediaCard compatible card, a Secure Digital compatible card, a Memory Stick compatible card, and a Universal Serial Bus (USB) Drive.

20. The apparatus of claim 12, wherein the activation event is in response to detecting a flash media to be connected to the flash media connector means.

21. The apparatus of claim 12, wherein the activation event comprises a user activation of a button on the apparatus.

22. A method comprising:

a flash media connector accepting at least one type of flash media;

detecting an activation event;

recovering data, in response to the activation event, the data corresponding to at least one application file from a corrupted flash media device coupled to the flash media connector;

the recovering data comprising searching for file indicia corresponding to at least one predetermined file type, reading data based on information in the file indicia, said data comprising recovered data, and storing the recovered data on the storage unit.

23. The method of claim 22, wherein the flash media connector accepting further comprises accepting at least one type of flash media either directly or via a flash media connector adaptor.

24. A method comprising:

a flash media connector accepting at least one of a plurality of different flash media;

reading a flash media coupled to the flash media connector means;

recovering data from a corrupt flash media coupled to the flash media connector means, in response to detecting an activation event; and

storing recovered data.

25. The method of claim 24, wherein the flash media connector accepting further comprises accepting at least one type of flash media either directly or via a flash media connector adaptor.
