i previously experienced data loss because i setup two 1.5TB drives as RAID0 and didn't have any backup... I don't want to make this mistake again!
So I purchased two 3TB drives to replace the two 1.5TB's that failed, and I plan to setup RAID1 in my OWC Mercury Elite-Al Pro dual enclosure (connected via USB).
When I plug it in, disk utility shows 1 entry in the left hand pane titled
"6 TB Ext Hard Disk Media"
and there are no indented volumes under this!
all the instructions I see online for setting up RAID1 would require there to be two separate 3TB drives, not one 6TB one.
I assume I need to partition the drive into two 3TB sections.. but if i do this, will it be smart enough to make each 3TB physical internal drive a separate partition? that way if i have failure in drive A, i can swap it with a new one while drive B is working fine since the drives were segregated in the RAID1 mirror setup?
any help is greatly appreciated. thanks in advance!
P.S. I started the erase process (with 'Zero Out Data option selected) since this takes awhile and i read online you should do this with new drives before setting up RAID to ensure no errors
