I'm closing this bug as after rebooting onto current linux 4.4.0-43-generic the problem went away. ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634005 Title: linux treats first partition on sdcard as much bigger than it really is?

blockdev also reports the wrong value:
# blockdev --getsz /dev/sdd1
32787056
strace shows that fstat() reports the wrong value.

Taking the first sector output and decoding it shows: 00 - 00 01 01 - 0c - 3f a0 00 - 00 08 00 00 - 00 00 10 00 00 - 00 81 01 - 83 - 3f 20 00 - 00 08 10 00 - 00 00 10 00 00 - 00 01 01 - 83 - 3f 20 00 - 00 08 20 00 - 00 00 20 00 00 - 00 01 01 - 83 - 3f e0 3f - 00 08 40 00 - 00 f8 79 03 Which looks correct, so I'm not sure whats causing it to think partition 1 is 16GB, is there some kind of special casing for sdcards? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634005 Title: linux treats first partition on sdcard as much bigger than it really is?
