Hello folks! This is my 1st post in this forum and would like some assistance. Apple had replaced a 3TB HD on my iMac and I currently have plugged in the old HD into a USB 3.0 enclosure which is Mac compatible. The issue is iMac recognizes the External hard drive as 'Macintosh HD' but I am not able to view the content on the HD. This is the error I am seeing when I click on the HD in Disk Utility program "This Fusion Drive is missing a disk. Would you like to rebuild this Fusion Drive?" Any suggestion how I can view data on this HD or do I need to Rebuild the disk which will erase all the data on the drive. Thank you.
