I own a Silverstone CS382 case, and I am using a 4 Port PCIe SATA Card with 4 SATA Cable, 6Gbps SATA3.0 Expansion Card, ASMedia ASM1064 chip to connect the bottom half of the hot swappable bays.

The drives in the bottom half no longer show up, and are missing on the array:
Here is a snippet of my layout from 7.0.1, prior to upgrading from disk layout plugin:


Here is what I see on the Array following the upgrade.
When I click the drop down for these missing disks I can only select the unassigned drive, which is unused due to smart errors:


Attached diagnostics, I have confirmed I am able to downgrade back to 7.0.1 and continue normal use without error, so unsure what could be occurring.
Any tips appreciated.

See last reply marked as solution. Replaced ASMedia ASM1064 controller with one using a JMB585 Chipset. Edited title for clarity as Unraid OS version is not related to issue

Please post diags from 7.0 for comparison.

servertwr-diagnostics-20250604-1143.zipAttached are diags from 7.0.1, running OK

The Asmedia controller where those two disks are connected was not detected by Linux with the 7.1 boot, this is typically not a software problem, please try upgrading again, it may have been a one-time thing, if the same, try reseating the controller, or using a different PCIe slot.

Moved my SATA controller up one PCIe slot.Confirmed Unraid booted properly, all drives still showing as normal on 7.0.1Updated again, this time to 7.1.3, and still have the same issue, same drives not showing up.
I see in the ASPM-status log file the following (from diagnostics zip), no ASMedia controller detected still:

I have also confirmed I am on the latest (last) version of my motherboards BIOS, 7.40 - Q170M vPro

Tested and found some additional details:

After a reboot of my system on 7.1.3, with a full power cycle from me checking my BIOS version, the array came up fine showing all drives.
Rebooted once again to be sure using the reboot button on the dashboard, and the drives do not show up properly this time...

Shut down system using dashboard power button. Confirmed the system appears off, no lights, etc. (did not toggle the PSU), and hit the physical power button to power the unit back on.

I have confirmed I can duplicate this by repeating either step above. Each time I reboot the system through the Unraid dashboard WebUI it fails to see the controller when it comes back up. When I shutdown using the dashboard shutdown button and then physically press the power button again to boot it back up, the drives show up as expected and the controller shows as expected in the ASPM-status log file, and the array appears normal and starts up fine.

I've attached both diagnostic zips, one for both scenario:
7.1.3 - Missing drives after WebUI Restart button - servertwr-diagnostics-20250604-1415.zip7.1.3 - OK after shutdown - servertwr-diagnostics-20250604-1411.zip

Clarity on physical power button being pressed after full shutdown.

Sounds more like a BIOS issue, disable fast boot and any other similar feature.

I checked my BIOS fast boot setting, it was already disabled.

I tried enabling some of the ASPM specific settings, but nothing helped. I'm considering looking for a different SATA controller to swap in.

After replacing the ASMedia controller with a 5 sata port JMB585 Chipset controller, 'soft' reboots work fine and all drives show up properly on either full shutdowns or Unraid OS restarts.
