I have a WD MyBook Studio II running on a MacBookPro with Mavericks via firewire. I have had no data loss but have also uninstalled Driver Manager, using the provided Uninstall tools.
I have filled mirrored 1Tb drives which I’ve swapped with 2x2Tb drives.
When connected the new empty drives only display as a single 4Tb drive. Disk Utility gives me the option to partition, but only as a single driver (RAID 0?)
How can I configure these to be mirrored (RAID 1) when I no longer have Disk Manager installed (and seem unable to download it)?
