USB3.0 external 4TB HDD on AC Adaptor is not recognised on PS3

So What I have did

I have created 2 Partion of 1.8 TB on my external HDD and made one as Logical and other one as Primary (thought some one will work)

Now I had connected my HDD with PS3 via Powered USB hub and one sigh of relief that MY BOOK is appearing but no Video file is showing up ??

I have copied jus two different video files in both partitions but apparently is not showing up

I know I am close but would b really happy once my HDD is working
