This must not work that way. Stripe size is array internal, neither user nor operating system knows anything about that.

Did you actually tested it writing things above 2TB barrier, reading them back and comparing MD5 sums? What OS was that? What device driver version? > 2.

I know it is possible via RS cable, I did that that way. I was only pointing out that it is not possible to change via LCD panel. It's up to you whether you change that or not. :) Anyway, thanks for your time. p. -- Beware of he who would deny you access to information, for in his heart he dreams himself your master. -- Commissioner Pravin Lal
