Hello, Thanks. Now I think that I am getting closer to something more concrete. My superblock says: superblock^.s_blocks_per_group = 32768 superblock^.s_inodes_per_group = 8080 superblock^.s_log_block_size = 2 -> so each block has 4k bytes And when reading the root "/" I obtain the following information for the directory /bin/ : inode=8081 So I calculate that it should have: groupnr=1 (because it is above 8080 inodes per group) offset for groupnr 1 --> 4k * 32768 = 0x8000000 But I have utilized a hex editor (oh boy, it was hard to find one that would read files over 4GB....) And the directory listing of /bin/ is located in aprox. near 0x21B0000 As if each block group would have a size of 0x2000000 .... but this size would be valid I would expect if superblock^.s_blocks_per_group=8192 ... Any idea what I missed here that the calculations went wrong? thanks, -- Felipe Monteiro de Carvalho -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
