Greetings! I'm testing different drive sizes in a Netapp DS14MK2 enclosure and I see that when I put a 3 TB drive in, FreeNAS sees the drive as 801 GB. I've searched the forums and seen that others have had similar issues. What I would like to do is resector the drive into 4096 byte sectors and see if there is some improvement. Can FreeNAS do this or should I boot into ubuntu and run SG utils for this?
