  I want to know,, if posibble to install raid in single hdd and how to configure that....The raid controller in server is H710 mini Thanks for ur reply  Yes, the RAID controller.  Which one do you have?  I'll assume a PERC H710 for now: The PERC H710 does NOT support non-RAID (you CANNOT use a disk alone without RAID) ... in order to use a single hard drive, you MUST configure a single-disk RAID 0.  This must be done in the RAID controller's BIOS utility, accessed by pressing CTRL-R during POST when prompted. Once configured, you MUST load the driver for the OS to see the drives attached to the controller. If you have an H310, it DOES support non-RAID, so you don't have to configure anything in the RAID controller BIOS, HOWEVER, you still MUST load the RAID controller driver during the install.
