After reboot I tried running 'fsck -f' but no additional data 'The
volume appears to be OK'. Output looks like:

m@air:~$ sudo fsck -fd /dev/sda5
fsck from util-linux 2.20.1
** /dev/sda5
        Using cacheBlockSize=32K cacheTotalBlock=1024 cacheSize=32768K.
** Checking HFS Plus volume.
** Checking Extents Overflow file.
** Checking Catalog file.
** Checking multi-linked files.
** Checking Catalog hierarchy.
** Checking Extended Attributes file.
** Checking volume bitmap.
** Checking volume information.
** The volume Macintosh HD appears to be OK.
