11 Actually ext3 is straight ext2+journal. Ext4 can read ext2. It may
12 be able to do small writes, but once it inserts its magic stuff, ext2
13 can't read it.
15 BTW, I see that your system is inserting junk after periods. Binary
16 view shows that where there should be 0x2E, it's 0x2E 0xA0

24 And also after closing parentheses. Should be 0x29, but is 0x29 0xA0.
