All I'm saying is that you should not blindly trust the disk. Another thing that raises my attention is in superblock_read(): memcpy(sbi->volume_name, layout->volume_name, sizeof(layout->volume_name)); Where do you check whether ->volume_name has a NUL terminator? Currently this field has no user, maybe will add a check upon usage. But this kind of things makes me wonder. Thanks, //richard
