I have a Mac mini Server Mid 2010, which is RAID1 by default. As a PC user for about a decade and never heard of RAID, I 'un'-RAID'ed my Mac and used the conventional partitioning instead. Today, the HDD are individual to each other. Then one dreaded day, my files was lost. Projects, documents and pictures (my mother was angry about this). The worst part is, I never had a backup. Then I realized, WTF did I do? Apple knows best. They set my Mac to RAID1 because they knew something horrible like this will happen in the future. I am troubled, I want to enable RAID1 again but Idk what to do nor where to begin. I am running on Mt. Lion right now. Please help me. Thank you!
