DEBIAN ….Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

So I’m getting corrupted error msg on my Raspberry PI:

[   48.261326] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

umount /boot
 git clone http://daniel-baumann.ch/git/software/dosfstools.git
 cd dosfstools
 make
 ./fsck.fat -a /dev/mmcblk0p1

Get this output:

 fsck.fat 3.0.26 (2014-03-07)
 0x25: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
 Automatically removing dirty bit.
 Performing changes.
 /dev/mmcblk0p1: 14 files, 1232/7161 clusters

And now:

 mount /boot
