Question HDD won't reformat or chkdsk properly, but all tests say it's fine

Bit of a weird one, I recently updated to the April monthly update thing through Windows update (I'm on Windows 10 Pro 22H2, annoyingly for some reason this defaulted some of my programs, which it has never done before, but more importantly, one of my internal HDDs started acting weird. It would seemingly act like it couldn't be accessed, like if I went into My Computer, the details of its size wouldn't show up, and the progress bar at the top would lag up Windows Explorer.

I tried to chkdsk /r it, the first time it got to the Security descriptors part, and then failed saying an unspecified error happened. I tried again after a restart and it got all the way to checking free space before giving the same error. Crystaldisk is telling me the HDD is fine, Seatools is also passing tests (It's a Seagate HDD), I even just ran Seatool's "Fix all", which completed, telling me the HDD passed... though oddly the progress bar was only about a third done when this happened.

Some googling led me to think reformatting might be the option, so I backed up the drive contents (which thankfully, it let me do) and tried to reformat it, after far too long of a wait, it told me the reformat failed. I tried this in Disk Management as well and got a similar error, so now the disk is in RAW format, so I can't even chkdsk again if I wanted to. (Also worth noting, Disk Management lists the drive as healthy as well)

I don't know what to make of this, is there anything else I should be trying to get it to cooperate? I'm very confused that everything is telling me the drive is fine when it clearly has something wrong.
 
Windows 10 was giving me BSoD's galore after this recent update and I had to bite the bullet and jump onboard Windows 11. Out of curiosity, how is the drive mounted in your build? If it's vertically mounted, maybe have it mounted horizontal with the bottom facing downwards.

How old is the drive in question? Make and model of your motherboard? BIOS version for your motherboard?
 
It's a Sata drive and indeed mounted 'normally', horizontal with the bottom facing downwards. The drive isn't too old, also I don't even really change the contents of this one very often, okay, I just looked at my emails, I think I got this one in 2017.

My motherboard is kinda old though, I'm not currently Windows 11 compatible because of it. It's an ASUS P7P55D-E, says the bios is version 1301 (27/08/2010).

That's concerning about your BSoDs, I guess this was just a terrible update.
 
Update, well that's interesting, tried to reformat it with Diskpart, says it got an I/O error, and now the drive has completely disappeared, it's not even in Disk Management as unallocated.

Edit: Ah, rescanning brought it back, but either way, Diskpart isn't working either. if I try to make partition primary it says there isn't enough space to do it, and if I tell it to reformat it says I haven't selected a volume, so... yeah.

replace the sata data cable
try different sata ports (the white ones are SATA III)

replace the BIOS battery

update the BIOS
download the latest BIOS file, unzip it to an USB flash drive, enter the BIOS, get to the menu "tools" and select ASUS EZ FLASH 2, select the BIOS file on the USB flash drive and wait till it´s done
