Im really confused by all this alignment, i already used 64, 1024 and now im on 128 (stripe 128KB, ICH9R, W7 with Write-Back cache).
Yeah in Diskpart I typed it in. For a 256 sector offset you need to type 128 because KB is used as unit instead of the number of sectors.

In my example it would be:

131072 Bytes / 512 = 256 sectors
256 sectors * .5 / 128 = 1
