I have tried everything I can think of to mount a drive to my DM500S and still haven't been able to mount a thing.

I've tried how to guides, but although the pictures are not remotely close to my screen set up, I have tried to decipher them as best I can, and to no avail.

I'm running OpenPLI at present, Jade3 previously without success... Can anyone help with this matter?

PS
Just to clear up what services I have used NFSdream/NFS, even tried in CIFS mode.
NFSDream always says box is busy when I try mounting from PC.
