| Post subject: | Format of raw CF img file? |
I used the HDD Raw Copy Tool to dump a copy of a compact flash drive to an uncompressed img file so I can poke around with the image to see what's wrong with it. I know the CF became corrupt, so I just want to see exactly what (byte for byte) was written in the wrong place. I have several questions about how to proceed: Is there a description of the format of the *.img file somewhere? <---- This is really what I most need Is the image in 1-1 correspondence with the bytes on the CF (or is there a header, tags, etc. in the file too)? Is the data on the CF serial, in the sense that there's a first byte, second byte, etc. ... and last byte? If it is divided into sectors, is there a description of how these sectors are organized (size, etc.)? I just want to use a hex editor to look around, not a tool that hides the raw content of the file. My thought is that I really want to manually poke around like you once could do with "Norton Utilities", or a low-level sector editor, but just using my hex editor instead. So I need to know offsets of interesting objects (specific sectors, FAT, etc). This is a little open-ended, but any comments or suggestions about documentation of the dump format would be appreciated. |

also checkout the datasheets of any chips in the Card, and see how they manage data, page sizes structure etc. this info will be chip specific, NOT image file specific. |
