unRaid 6.11.5

Thank you in advance to anyone taking a look. I'm in the process of transplanting my Unraid server from an i9 9900 with 32gb of ram on a b365 board to an i7 13700k on a z690 board.I've spent all weekend fixing different problems (incompatible ram, usb flashback wasn't working, turning off secure boot wasn't sticking). I've finally got the server booted and can access it from my laptop. Now my next (and hopefully final) issue is that my MB isn't detecting two of my drives. I've tried different combinations of power and data cables, both directing to the motherboard and to my LSI 8i card that's split into 8 sata cables.

It's always the same two drives. I tried a suggestion from another post and inserted "pcie=realloc=off" into the syslinux.cfg with no change. My next step is to order a sata expansion card to try and avoid the MB ports altogether. If anyone has any suggestions, I would greatly appreciate it. syslog is attached.

Always the same two drives - Could it be the same two MB SATA ports?  A number of motherboards disable some SATA ports when NVMe slots are populated (as there are only so many PCIe lines to go around).

Have you changed power supplies during this hardware swap?  Are the drives that are not detected drives shucked from external enclosures?

I had that same idea. I tried those two drives connected to the MB and the HBA card and it's still those same two drives that aren't recognized. Super weird.

I did not change out the PSU. I am using the same 1000w platinum corsair PSU. Both drives are from 8tb easy stores. I did not pull the 3.3v pin or cover it. Instead I got a 4 port extender and cut the cord closest to the "bend" in the sata power connector in order to not send power to the first 3 pins.

Well, if you have not changed PSUs and the drives were previously working with the SATA power mod, the 3.3v reset issue should not be the problem.

Let's say, worst case scenario, that I decide that those two drives are dead and I have to buy replacements. I can't rebuild single parity. How can I recover as much data as possible with the two new disk?
