My DVP 5960 isn't detecting my external harddrive.

I formatted it as a logical 60 GB fat32 partition; the external enclosure has a dedicated power line, I connected it, powered up the external enclosure, then turned on the player and got "unknown disc."

I read up the thread on external HDDs and the dvp, and most people are getting their drives to work. What might my problem be?

That's the enclosure i'm using, and the harddrive is some old ide drive.

Might firmware versions be causing a problem?

Reformated with swissarmyknife and made it primary. Works fine now.

So yeah it has to be formated as a fat32 primary drive in order to work
