Ok.. I downloaded the acu and installed it... It shows me the current array with one logical drive of 300 GB that consist of 2x300 physical drives. I made expand and then extend it in the new unused space... but the new extended logical drive is not 600 GB as it should be. It is 558.7 GB (!!!). Also the RAID changed from RAID 1 to RAID 1+0 (!!!)

Ok found it... hard disk's nominal space value is in decimal so 300 GB is 300x10^9 bytes so if I divide 300 with 1.073741824 then everything ok...
As far as the RAID level changing I think you'll find it said RAID 1+0 before when you had two disks even though technically that's RAID 1 rather than 10. Unless they've changed it in the latest version the ACU calls RAID 1 RAID 1+0 because the algorithm is the same in that you skip to the next pair after writing one stripe element, it's just that the next pair is the same as the current pair with only 2 disks.
