If you want to find a way to access the raw data in NAND memory feel free. I won’t say it’s impossible however I will say there are hundreds of different controllers from many manufactures and there is no “public” universal interface to do this.
I believe some recent "state-of-the-art" flash devices meet new standards (don't recall for certain) but fyi
- The Open NAND Flash Interface Working Group (ONFI) has developed a standardized low-level interface for NAND flash chips. It released its first spec Dec, 2006. Also
- The Non-Volatile Memory Host Controller Interface (NVMHCI) Working Group includes a group of vendors, including Intel, Dell, and Microsoft. Its goal is to provide standard software and hardware programming interfaces for nonvolatile memory subsystems
I don’t believe your diagnosis of his problem is correct, and I have the feeling you think mine is just as wrong so I’ll leave it at that. If he can’t get his data with your methods he can contact me or any other data recovery shop that specializes in NAND memory.
My last post didn't so-much focus on the OP's particular problem but rather on the topic of data recovery based on LUT failure. I, without doubt, agree no software can recover if, in fact, there's hardware damage (again back to my whole point of just addressing: hardware damage vs. data corruption) and not necessarily categorizing the OP's problem in this case.
just trying to add some info to the forums.....
