I have had a 1TB MBWE for a while on my Windows-only (no Linux) network. It's been a rock-solid performer. Absolutely no problems. It's slow copying files to/from but that's not a problem for me. I use it as a place to hold DIVX/XVID videos that I stream to my XBox and the streaming speed is more than adequate to view the videos. I never installed MioNet because I don't foresee ever needing to access the MBWE remotely.The drive is almost full.
I liked my 1TB drive so well that I purchased a 1.5TB drive. As before, I did not install MioNet. I renamed the device "mybookworld2" so that I started to copy files to it. As noted in another post, after about 100GB of videos were copied, something happened and I now only have read-only access to this drive. I can't delete files or add any new files to the public folder. I've turned it off and back on and nothing seems to work. (That's the subject of a separate post).
Anyway, that got me wondering whether 2 of these things can peacefully co-exist on the same (Windows) home network.
Thanks to all of you for sharing so much helpful information!
