How did you create file system? That was some time ago, so I'm unable to answer this question. But nilfs-tune shows 4KB blocks: ~ # nilfs-tune -l /dev/sdf3 nilfs-tune 2.1.6 Filesystem volume name: (none) Filesystem UUID: 53760664-f9ed-4c8d-af42-c6ee2f16d956 Filesystem magic number: 0x3434 Filesystem revision #: 2.0 Filesystem features: (none) Filesystem state: invalid or mounted,error Filesystem OS type: Linux Block size: 4096 Filesystem created: Fri Aug 3 08:37:06 2012 Last mount time: Mon Mar 24 07:55:53 2014 Last write time: Mon Mar 24 07:58:04 2014 Mount count: 100 Maximum mount count: 50 Reserve blocks uid: 0 (user root) Reserve blocks gid: 0 (group root) First inode: 11 Inode size: 128 DAT entry size: 32 Checkpoint size: 192 Segment usage size: 16 Number of segments: 922 Device size: 7741636608 First data block: 1 # of blocks per segment: 2048 Reserved segments %: 5 Last checkpoint #: 770589 Last block address: 595617 Last sequence #: 41763 Free blocks count: 395264 Commit interval: 300 # of blks to create seg: 0 CRC seed: 0x3e0bea06 CRC check sum: 0x2596b671 CRC check data size: 0x00000118 > Could you share the superblock content? If my calculations are correct (it's the second superblock, right?), it should be: dd if=/dev/nilfs of=dump bs=Block size skip=Device size / Block size - 1 count=1 Attached this one. > > Should I check the card in the first place? > > > > Currently, I suspect that you have bad SD card.
