My Raspberry Pi went into KBD Mode displaying this message after I unplugged it directly without shutting it down after it stopped responding. How can I fix this from a Mac, which is the only laptop I have access to, or access the files and filesystem from the SD Card to recover the files as if I just plug it in I only see about 10 files?

I cannot post a photo as I don't have enough reputation but it seems to be the standard error message that is associated with KBD.


You're only seeing 10 files because the Mac is mounting the FAT32 partition that holds the Raspberry Pi's bootstrap code and kernel images.

The Raspbian images shipped by the Pi Foundation split the SD card up into two partitions: the aforementioned FAT32 partition holding kernels and bootstrap code, and an EXT4 partition that holds the actual Linux filesystem, including all user data.

Mac OS X doesn't support the EXT4 filesystem natively, so you can't mount the partition directly and retrieve the data; however, take a look at the accepted answer on this SuperUser question for a possible way to mount it.

    Similar to the SuperUser question, I am also using MacFUSE and fuse-ext2, and it works fine for mounting Linux ext* filesystems. I would also suggest to use OSXFuse, as MacFUSE doesn't seem to be maintained anymore.

  • Hmm, I just tried this and get the following errors: Downloads $ sudo fuse-ext2 ./2013-05-29-wheezy-armel.img /Volumes/wheezy -o ro fuse-ext2: version:'0.0.7', fuse_version:'27' [main (../../fuse-ext2/fuse-ext2.c:324)] fuse-ext2: enter [do_probe (../../fuse-ext2/do_probe.c:30)] fuse-ext2: Error while trying to open /Users/matthew/Downloads/2013-05-29-wheezy-armel.img (rc=2133571347) [do_probe (../../fuse-ext2/do_probe.c:34)] fuse-ext2: Probe failed [main (../../fuse-ext2/fuse-ext2.c:340)]
