Sorry to resurrect an old topic, but I haven't seen this posted anywhere else.
I've got a 3GB USB HD attached to this router. Seems to work fine, but - Is there a solution to the issue mentioned above of access via the LAN to an attached drive (no credentials)?
I just bought this, but I do not feel comfortable with anybody on my network (wife, kids, kid's friends, etc.) having read/write access to my attached drive.
