PLAYSTATION 3 and External Hard Drives

Recently I bought a external 500 GB hard drive to back up my iMac. I hooked it up to my PLAYSTATION 3 to see if it would see it. And it saw it just fine. Then I starting browsing through the backup data I had. I couldn’t’ go any deeper into the files. Seems the PS3 can only go 7 file folders deep into a hard drive.
I made 3 folders in the root of the hard drive (MUSIC, PHOTOS, VIDEO). Then copied over the media to the correct folder. In the Music folder I just copied over my whole iTunes library. I went to the hard drive under music. The iTunes Music folder showed up then I went into that folder and it said “There are no tracks”. So Then I tried Photos. I put all the photos in separate folders in the photo folder. Went to the hard drive again under photos. Got this “There are no images”. Ok, let’s try video. I put folders inside the video folder as well. It saw 3 folders. And the PS3 also saw the video files in those folders as well. But the I have the files folders set up as PSP > Family Guy > Then Actual Video Files. It didn’t even see that.
So instead of trying to work around this. Go to your hard drive then press Triangle & X. This will “Display All”. Then it will see all the folders you’ve made. But remember it only goes 7 file folders deep.
