Ok, I got myself a 1TB WD external hdd from Officeworks $199. Great buy. The real trick here is that the primary directories as mentioned earlier must be in caps, MUSIC, VIDEO and PICTURE and then within these primary directories you can have "a" sub directory for say a music album (eg. MUSIC/Metallica - LOAD/), or video etc. There is no other way to make it work, well on the 40gb ps3 I have, triangles or otherwise.
