    I am selling off my Mac mini and during the drive formatting the power cut out. Upon restart it asked me if I want to 'fix' the hard drives to work again and now they have been merged into one partition. Any advice how to undo this?

    Tell us more about the Mini, including which drives are inside it.

    Sounds to me like you have both an HDD -and- an SSD, and Disk Utility has assumed that they're suppoed to be "fused" into a fusion drive, and did just that during the re-initialization process...
