I wanted to dual boot Win10 and Linux, so I started to resize the partition in the Linux installer and realized I couldn't. When I tried to resize with gparted, gparted said that the drive was encrypted. I have Windows 10 Home, so I didn't think it was bitlocker. I rebooted into Win10, and found "Device Encryption" and disabled it. Windows prompted that decryption could take a long time - but it didn't at all. I rebooted and was able to resize the partition in the Linux installer.
I'm unable to figure out how to reenable encryption. If I set a HDD password in the BIOS, it just asks me for a password on boot, so that's not it. I can't encrypt with Win10 Home edition, so it wasn't done with that initially. I downloaded Samsung Magician, but it doesn't support the drive.
I have a Samsung MZVLW1T0HMLH-000L7 drive which is a 1 TB SSD OPAL2.0 PCIe-NVMe. I've read that the OPAL drives are hardware encrypted, but I can't figure out how to turn it back on, or even for that matter, why I was able to disable it in Windows. Does anyone know how the drives are encrypted from the factory so I can get this encrypted again?
