SSD missing space

hello all!

i've got 2011' mbp few month ago 128go ssd.

morning ssd full , deleted files. checked info of ssd says :
capacity: 120.47 gb
available: 12.54 gb

(data = 100gb). when use daisy disk or sums "get info" of folders in ssd end 62gb of data.

cleaned ccleaner, stopped local time machine backups (i think stopped), stopped sleep option (in order delete sleep image , save 4gb). rebooted. , had same problem. when checked info of ssd have :
capacity: 120.47 gb
available: 17.03 gb

here's screens :
- daisydisk: http://cl.ly/2h1r2s2h1c0z342v3j38
- "sudo du -hs /" in terminal: http://cl.ly/2i0d423i1u1t0i2t3l2b
- ssd quick look: http://cl.ly/3o3l1f2u243124133f29
- info of folders in /: http://cl.ly/45111q1g3g0x0r2g2x1t

can see there around 45gb of data missing/lost between occupied space quick , total of folders.
