It might be that the bios isn't prepared for a 4k-native drive......

If you boot with the drive connected, the bios finds something it doesn't know/ like. Disk will probably be checked if it's bootable only in AHCI mode and ignored in Raid and IDE mode...
If you add the disk after system boot the disk needs only to be recognized by the operating system....

Yes, I've considered 4k all along, and this BIOS should be plenty ready for such. I know you didn't want to install windows, I was only asking for that as test, sorry if it was confusing things here, I know you wanted for storage all along.
When you did update the RAID Roms, did you update both legacy and UEFI? Neither should be loaded/used unless you are using RAID, but I don't know with 100% certainty that some part of it isn't used for AHCI, since there is no AHCI module anymore in these modern BIOS and the legacy one is usually named SATADriver.

If you did not update both, I will make you a BIOS to test Other than that, getting Gigabyte to test exact scenario with exact disk (they will have, and will do test) via email is all I can think to do here.
I no longer have amy Z97 Gigabyte boards, but I may have a H97, I will check and see and test if I do

Well, I checked on the C222 mini-server board I own (ASUS P9D-I), there's an announcement for 4k support (bios 808), ~2015. No difference in SATA efi module and it still has an AHCI efi module, but there's not too much difference either between both versions:


I don't think it'll be easy to find out what it needs....

Edit:
They contain both the same RSTe version (3.7.0.1049)

I will test with WDC WD40EZRX, but I'll have to move all my files off it first, so give me a few days to sort all that out and do some testing

To clarify, I was asking if, when, you updated the RAID Roms, did you update both legacy and EFI in the BIOS at same time? In BIOS when you update the RAID Roms, there is two modules to be updated, so I was asking if you did both when you tried that previously?
UBU will update both, if you tell it to do both, and it's up to you to insert both modules into the correct folders before running UBU. Sounds like you did both, so I guess this is out as possible fix.
I assumed it wouldn't matter anyway, since RAID means RAID and this is ONLY used when you use RAID, but worth a shot since one of them is named SATADriver module-wise in the BIOS.

Gigabyte will get back to you in support system, sometimes it take a bit, but probably much longer now due to coronavirus slowing everything down
But, they will get back to you, and if you sent them specific case info (HDD model used, exact scenario to create the issue etc) they will test that exact scenario and either tell you how to not make it happen, or send you a fixed BIOS.

I checked my board pile, and sold all the Z97 and H97 from Gigabyte I had, so I can't test myself
I was really hoping and thinking I still had a H97 to try this with, I know it wouldn't have been the same, but maybe if I could have found the issue on my end I could find solution, but no dice

Wait a sec!! I did a double check just now in my old board for sale list, and I found I do have a Z97X-UD7 in pile somewhere! So, let me dig that up and see if I can figure this out
I will test with WDC WD40EZRX, but I'll have to move all my files off it first, so give me a few days to sort all that out and do some testing

I've opened the BIOS file in MMTool, and there are "ahci", "ahciSmm" and "ahciMmioSmm" modules. What could happen if I replace them with modules from other board (from GA-B250M-D3H perhaps)? Though I don't see "ahciMmioSmm" module in GA-B250M-D3H BIOS file...

Please edit your posts if you need to add more info, questions etc, and no one has replied yet. Thanks

So, you don't think WD40EZRX will give us valid test scenario? If not, we may have to wait on this, at least for me to test, I will need to purchase a 4TB 4K native drive. I am looking to buy another 4TB drive anyway, so this gives me good chance to do soon as I can!
Can you please look at Amazon for me, and show me what WD models you find 4TB that are for sure 4K so I look at pricing on the correct ones.

And keep in mind, once you get replies going with Gigabyte directly, they will resolve this for you too, so there is no massive rush to get this done Asap.
Use your drive otherwise for now (ie in RAID mode, with OS and single disk non-member), until we get this sorted out. This is ideal solution anyway, I would have just used this from the get-go and never messed with all this testing.
I used to run non-member RAID mode always with a single OS SSD and HDD before that, on purpose

Sorry, must have seen all those replies as you, didn't notice . I was replying to you, and or him (about the disk I have I guess)

@Tacis - does the size of the partition matter? I think maybe we discussed, but I looked back to be sure and I can't see it If not, maybe I can use a NVME or SSD?

@lfb6 - would that work? ^^ Or, do you think for a valid test I need an actual 4K native HDD? If yes, can you show me which models are cheaper ones on amazon, if you don't mind - thanks!

I know they will test and resolve if we can't, just have to wait it out

Thanks, hopefully maybe I can test with SSD or NVME where I can set my own sector size, hope lfb6 will know if that would be valid substitute or not.
In meantime, while you wait on support via ticket system, you should get a thread going at both of their forums too and see if any official reps will step in and test on their end as well
https://forum.gigabyte.us/
https://forum.giga-byte.co.uk/index.php

https://forum.gigabyte.us/ - zero response
https://forum.giga-byte.co.uk/index.php - still waiting for account approval (since Thursday)
https://forum.gigabyte.ru/ - "just get rid of that HDD"

Well, at least they will reply to you for sure in the ticket system, and hopefully you get good tech that will setup test right away, if not ask them to directly and they will (usually they show proof of test too, images etc)

Doesn't Motherboards typically allow you to disable a SATA Port in the Firmware? Yours do. Can the Port be re-enabled AFTER Windows boots so that it detects the HD?
Basically, connect the HD with no Partition Table (No MBR nor GPT, totally blank) so that it doesn't freezes on POST, disable its SATA Port in the Firmware, create a Partition Table and try again. If it doesn't crash, maybe you can get it to work Windows-side at a later stage.
