I have N2050 and love it so much, it's too bad that I cannot use the eSata connection (I use Promise TX4302). I've tried update the WIndows or went through the Control Panel without no success. I asked in other forums and I got a reply that it's a common problem with N2050 not recognising eSata.
And I haven't found any solutions from anywhere so far, not even from the Thecus website.
I'm hoping to get a solution here as my last resort.
