Is there ANY USB or other storage device attached?
Why I ask is that far too many times over the decades I've bumped into this with a corrupt diskette, drive or other media. Let's get that out of the way first.
If that doesn't apply, read http://www.samsung.com/us/support/supportOwnersHowToGuidePopup.do?howto_guide_seq=6833&prd_ia_cd=N0000442&map_seq=45819
After 2 weeks I have got my first problem with my chromebook.
When I want to open the folder Files, it is searching endlessly, for around 4 hours anything will change.
Anyone had this problem before ? or know how to fix it ?
