How can I reconfigure a LaCie Big Disk Extreme so that Mountain Lion will see both of its disks?
Once, years ago, I accidentally did something bad to a LaCie device. Where normally its two disks appeared to Mac OS X as one larger disk, the accident caused the two smaller disks to appear. At the time, I chose to resolve the issue by reinstalling firmware with a LaCie-provided utility.
Now: I probably need to 'break away' from that RAID-oriented firmware – intentionally, not accidentally.
I don't want to create two volumes, neither can I place the disks in different enclosures.
I want to work with the two separate disks with the current enclosure, so that I can experiment with things such as ZFS.
When I last checked, in 2012, LaCie's firmware utility for this class of drive could not run on Lion.
Data in this enclosure is, always will be, disposable.
