I recently upgraded server 2012 essentials to 2016 essentials. I reformatted the SSD for the OS and did a clean install. After everything booted up I turned the server of and then plugged in the 3 hard drives I had running nder 2012. I cannot see or find any of the folders or files even thogh the hgard drive volumes say they are there. This sounds like a permission issue but I need to know how to recover the old file folders as they had irreplaceble pictures and financial dats in them. Any sugfgestions?
