I am trying to set up a computer with a RAID 1 configuration using 1 x WD Green (500 GB) and 1 x WD Blue (500 GB) drives. However I am getting an error when trying to add the Blue drive as a mirror. A dialog box named "Virtual Disk Manager"pops up with the following error message: "All disks holding extents for a given volume must have the same sector size, and the sector size must be valid".
Both disks are brand new and working. What am I missing? Are the drive incompatible for mirroring although they have the same size?
