I'm trying to create a windows 10 partition on a raid 6 raid array for a direct attach - the raid group was done with Atto configTool and is attached to the PC with an ATTO R680 raid card with all new drives - the PC disk management page sees it - Drive 2 -basic - online and unallocated - i have followed all the steps for doing a simple volume and go all the way to finish and I get a dialog box that tells me the parameter is incorrect - I've tried different letters for assignment but nothing seems to change - I know it has to be something simple - any thoughts - thanks
