Field-operable, stand-alone apparatus for media recovery and regeneration
View Patent ↗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.
1. A method comprising:
accessing data on a flash media;
searching the data for file indicia corresponding to 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.
2. The method of claim 1 , wherein the flash media comprises one of a CompactFlash device, a SmartMedia card, a MultiMediaCard, a Secure Digital card, a Memory Stick-compatible device, and a Universal Serial Bus (USB) Drive.
3. The method of claim 2 , wherein the USB Drive comprises a storage device built from at least one of a magnetic medium, a NAND Single Level Cell (SLC) flash, an Assist Gate-AND (AG-AND) flash, and a NAND Multi Level Cell (MLC) flash.
4. The method of claim 3 , wherein the USB Drive comprises of one or more chips built from at least one of the NAND SLC flash, the AG-AND flash, and the NAND MLC flash.
5. The method of claim 4 , wherein the one or more chips are cascaded.
6. The method of claim 1 , wherein the storage medium comprises one of a CompactFlash device, a SmartMedia card, a MultiMediaCard, a Secure Digital Card, and a Memory Stick-compatible device.
7. The method of claim 6 , wherein the MultiMediaCard is accessible in serial or in parallel and the MultiMediaCard comprises at least one of a Reduced Size MultiMediaCard (RS-MMC), and a MultimediaCard High Speed (MMC HS).
8. The method of claim 6 , wherein the Secure Digital Card is accessible in serial or in parallel and the Secure Digital Card comprises at least one of a mini Secure Digital Card (miniSD), a Secure Digital Card High Speed (SD HS), and a Trans Flash.
9. A method comprising:
determining a media type of a flash media;
building a physical-to-logical table mapping physical storage locations to logical storage locations based on a media type of the flash media;
searching the flash media for a file header corresponding to at least one predetermined file type using the physical-to-logical table;
reading data from the flash media based on information in the file header to recover data corresponding to at least one application file from the flash media; and
storing the recovered data on a storage medium.
10. The method of claim 9 , wherein the flash media comprises one of a CompactFlash device, a SmartMedia card, a MultiMediaCard, a Secure Digital card, a Memory Stick-compatible device, and a Universal Serial Bus (USB) Drive.
11. The method of claim 10 , wherein the USB Drive comprises a storage device built from at least one of a magnetic medium, a NAND Single Level Cell (SLC) flash, an Assist Gate-AND (AG-AND) flash, and a NAND Multi Level Cell (MLC) flash.
12. The method of claim 11 , wherein the USB Drive comprises of one or more chips built from at least one of the NAND SLC flash, the AG-AND flash, and the NAND MLC flash.
13. The method of claim 9 , wherein the storage medium comprises one of a CompactFlash device, a SmartMedia card, a MultiMediaCard, a Secure Digital Card, and a Memory Stick-compatible device.
14. The method of claim 13 , wherein the MultiMediaCard is accessible in serial or in parallel and the MultiMediaCard comprises at least one of a Reduced Size MultiMediaCard (RS-MMC), and a MultimediaCard High Speed (MMC HS).
15. The method of claim 13 , wherein the Secure Digital Card is accessible in serial or in parallel and the Secure Digital Card comprises at least one of a mini Secure Digital Card (miniSD), a Secure Digital Card High Speed (SD HS), and a Trans Flash.
16. A method comprising:
determining a media type of a flash media;
identifying a damaged file system component;
employing a lookup table containing file system parameters to rebuild the file system component based on the media type of the flash media to generate rebuild data; and
rewriting a corrupted portion of the flash media with the rebuild data.
17. The method of claim 16 , wherein the flash media comprises one of a CompactFlash device, a SmartMedia card, a MultiMediaCard, a Secure Digital card, a Memory Stick-compatible device, and a Universal Serial Bus (USB) Drive.
18. The method of claim 17 , wherein the USB Drive comprises of storage built from at least one of a magnetic medium, a NAND Single Level Cell (SLC) flash, an Assist Gate-AND (AG-AND) flash, and a NAND Multi Level Cell (MLC) flash.
19. The method of claim 18 , wherein the USB Drive comprises of one or more chips built from at least one of the NAND SLC flash, the AG-AND flash, and the NAND MLC flash.
20. The method of claim 19 , wherein the one or more chips are cascaded.
21. A method comprising:
determining a media type of a flash media;
identifying a damaged file system component;
employing a lookup table containing file system parameters to rebuild the file system component based on the media type of the flash media to generate rebuild data; and
rewriting a corrupted portion of the flash media with the rebuild data.
22. The method of claim 21 , wherein the flash media comprises one of a CompactFlash device, a SmartMedia card, a MultiMediaCard, a Secure Digital card, a Memory Stick-compatible device, a NAND Single Level Cell (SLC) flash, an Assist Gate-AND (AG-AND) flash, and a NAND Multi Level Cell (MLC) flash.
23. The method of claim 21 , wherein the method comprises a cell-phone.
24. The method of claim 21 , wherein the method comprises a smart phone.
