NVMe SSD in M2_2 slot not detected after sleep mode

MB: ASRock Z370 Extreme4
BIOS version: 4.21B
M2_1 slot: Samsung SSD 990 EVO Plus 1TB
M2_2 slot: Samsung SSD 990 EVO Plus 1TB

I have 2 identical M2 SSD drives in M2_1 and M2_2. I have no other driver connected in this PC.
When I resume Window 11 from sleep, only one drive shows up, the one in M2_1. The second M2 is not recognized at all. Even if I restart the computer, the M2_2 slot is still dead. I have to completely shut down and then the M2_2 drive shows up in BIOS.

I tried disabling Deep Sleep in BIOS but it did nothing.

Looked for a new BIOS version, but couldn?™t find one.

If someone can help with this, I would greatly appreciate.]]> Tue, 23 Sep 2025 00:50:53 +0000 https://forum.asrock.com/forum_posts.asp?TID=113340&PID=199043&title=ssd-not-detected-after-sleep-mode#199043
