Comment 33 for bug 112402

I found the meta data. I ACTUALLY found it. thanks for the zeroing hint Phillip, I completely zeroed both disks, to be sure, as there was all sorts of stuff I didn't know. I narrowed it down and found it located on /dev/sda at sector 156297345.

After narrowing it down I ran :

sudo dd if=/dev/sda of=outputfile skip=156297345

then :

sudo hexdump -C outputfile > outputfile.txt

I started by dumping the last 5 megabytes of disk space and looking at it in a hex editor, then just counting how many bytes it was to the data. with that I figured, well, 512 bytes a sector, so some easy math to the meta data. Then I double checked by comparing the 5mb output to the one I concluded with.

I don't know if I should, but heres the hex dump, probably formatted crazily:

Anyways, I'm uploading my results, the hex dump text file, the original output file, and a hex dump text file with a summary of this and my fdisk output. I'm gonna look at the dmraid source my self, but I doubt I can do that stuff. Thanks!
