I have 4 1TB drives. Currently running a RAID 0 volume of 3 drives and 2TB (rest unallocated.) These are WD Cavier Green drives. Also have a Segate 1TB drive (exact same specs.) and want to add it to the Array. No option in Matrix or Rapid Software. On boot it says its a non-member disk. My goal is to run all 4 drives in Raid 10 (I hear raid 5 is slow / buggy). I've tried everything to add to array or create a new volume, but it won't let me add! I have BIOS not EFI but only want a 2TB volume - not sure why I can't add a 4th drive. tried several versions of Intel ROM/Software.
Should i just reset drives and rebuild? Why can't i add the Segate drive? Will i lose data? Any other config suggestions???
