Q: Missing space HD after deleting Bootcamp

After I tried deleting a bootcamp partition using Disk Utility, there seems to be some space missing in my HD.

The size of my Bootcamp partition was 100 GB, and my Mac partition 400 GB, but now, in "About This Mac", it shows "24,09 GB free of 429,25 GB", and it doesn't display the categories (Images, Videos, etc), only "Other".

Here's what is shown in Disk Utility:

This is what I get by typing "diskutil list" into the Terminal:

/dev/disk0 (internal, physical):

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *500.1 GB   disk0

   1:                        EFI EFI                     209.7 MB   disk0s1

   2:                  Apple_HFS Macintosh HD            499.2 GB   disk0s2

   3:                 Apple_Boot                         650.0 MB   disk0s3

And "diskutil cs list":

No CoreStorage logical volume groups found

Any ideas?
