So I just completed making some adjustments to my cable management for my desktop and now Windows 10 fails to detect one drive or the other. My primary drive and the secondary drive both have windows 10 installs on them as I'm currently still migrating files from the HDD to the SSD and still need to access some of the software and files on the HDD whilst running the install on the SSD. In my boot setup both drives are detected and bootable and booting correctly. The issue comes as before re managing my cables with the SSD set as the primary boot I could still read and access the files on the HDD from explorer. Now the second drive doesn't show in explorer or disk managment.
