How do you do that? I have a PS3 and I would like to do the same. Thanks.
I have a WD MyCloud NAS drive that is cabled directly into my wireless router. My PS3 happens to be right next to my router, so I have that cabled via ethernet as well (to ensure max bandwidth). Then in the PS3, there is a feature you can select that says something like "scan for media servers". When the scan is complete, it should pick up your NAS. Then you connect to it via the PS3 and it will do a scan of the drive and catalog your media by folder, artist, album, etc.
It's been a while since I hooked it up. But I think when you set up the NAS, you may have to enable an option that tells it to act as a media server. I can't remember, but that option may have come enabled by default.
Here are some instructions from the PS3 site that might help.
