Hi genghiskhen and welcome to the forum
Yeah, I've read about the issues some people have with Advanced Format Drives but never having hit the issue myself (despite having a whole bunch of 2TB drives in my server) I didn't feel comfortable adding a how-to that I'd not tried out myself. Everything on the site is tried and tested by yours truly so I can vouch for its accuracy (and I do update it as and when required). If you happen to have a link for a guide that you've followed, and had success with, then please feel free to post it here.
So, care to share your setup? What are you using for clients, the HTPCs? What software have you installed on your server? Apart from the drive formatting problem did you hit any other issues?
What made you decide to finally centralise everything?
Sorry for all the questions sir, but I enjoy reading about other people's setup and sharing ideas with folks. And if you're a unix veteran then maybe you can teach us all a thing or two
