Hard drive failed or frozen? fix?

My WD network harddrive doesn’t mount. I’m on a mac, and it shows up in the finder, but when i click on it, it says connection failed. it also shows up on the ps3, but if i click on it, it shows no files. there are tons of files.

I’ve tried different cables, and i’ve tried plugging it directly into my computer - no worky.

Please help me fix this. 

Hi there, are you able to ping the drive and check for errors/confilc under network utilities? (Click on go> Utilities> network utility).
