Startup Disk almost full, but only using 2/3 of drive?

Hey,
Weird thing happened today. Startup disk is almost full warning showed up.
Thats odd, 128gb samsung SSD, shouldnt be full. I have icloud photos and a couple office and adobe apps, but thats about it on here.
So I opened omindisk sweeper, and it calculates 73gb used.
Any idea what I should do to find / delete whatever is taking up the space? obviously, I rebooted but that doesnt seem to help. And Omnidisk is reading lower than the OS sooo....

See image below of my storage, vs omnidisk.
Running 10.11.4

I would try re-indexing Spotlight, since that's where About This Mac gets its data.

I'll try that. Thanks. Spotlight sucks. It won't give me results for Google / Bing like it's supposed to, never finds any of my music, about all I use it for is the calculator.
[doublepost=1463596182][/doublepost]Well I dont know which did it, but i reindexed the disk, turned off local snapshots (its connected to the TM via eterner, and Ive disabled it before..) and rebooted. Something seems to stick. reading 39gb free.
