I like to share with you my method. I had a 500GB SATA Hard Drive and Windows wont see the data after install until you add it to Disk Management as a Dynamic Disk because it somehow it became a dynamic disk in the past. I not sure why. For it to be seen as a Basic Disk like all the rest of your drives you have to convert it to Basic but this means you lose all your data so say Microsoft. I didn’t want to lose 500gb of data. So here’s a hack to convert it to a Basic Disk without losing any data. It also means i can access the drive in dos properly too.
