Hello! I bought a Samsung 970 EVO SSD a while ago and only finally installed it last night after my other drive filled up. My mobo is a Gigabyte Z490. My original boot drive (same model) is in the M2M slot and I installed this one in the M2A slot. These are the only drives installed so no possibility of SATA conflicts. The manual doesn't say anything about what order to use these slots, so I'm guessing it doesn't matter (the final slot is blocked by my CPU cooler so I haven't tried it yet).
On my first attempt, I couldn't get the drive to show up anywhere so I reseated it. Now it appears in BIOS and Windows prompts me to initialize it as Disk 1. However, I immediately get a "A disk device which does not exist was specified" error when I attempt to do so. The disk remains visible in disk management until I restart, and then it disappears entirely from both the BIOS and Windows. I can reliably restart this process by completely shutting down, cutting PSU power, and then booting back up.
Any ideas?
