Intel Optane H10 512GB not detected

[Nawab29]

I bought an HP Pavilion 16 Gaming-ab202 laptop in 2021 which came with a preinstalled Intel 512GB + 32GB Optane SSD. It came with Windows 10 that I later updated to Windows 11.

On 30th October 2025, my laptop started crashing with a blue screen error "Inaccessible Boot Drive". Every time I force shut it down and start again, the laptop would work fine for about 5 minutes then freeze and crash with the same error.

I assumed a recent Windows update was causing it so I uninstalled it from the windows repair screen. But the probably persisted for 2 days. On third day the SSD would randomly be not recognised on bootup. Sometimes it would be recognised and load the windows which would crash again with the same error.


Now the SSD isn't detected at all. I've check via Diskpart command in cmd as well as the BIOS.

The computer does however detect the Optane part of the SSD as usable space of 27GB. But the main NAND part of 512GB is not accessible.

I've tried repairing the computer and installing drivers from HP support as well as the ones available for 10th & 11th gen chips from Intel site as well but to no avail.

I would like to know what can cause this and what can I do to get the drive back. I don't mind losing the data since most of it was backed up on One Drive.

Here's some details about what it shows me now in the HP BIOS:

Configuration > UEFI HII Configuration >Intel RST

Non-RAID physical disks
TG 4.0, INTEL HBRPEKNX0202AHO TE0366062C512B-2, 27.2GB

The RST driver version in the BIOS is 17.8.0.4507. It didn't update even though I installed the latest driver available on Intel website which is 18 something.


In the Intel Optane Memory and Storage application it lists the SSD as the following in two parts:

1- PCIe Intel Optane Memory H10 with SSD
2-Disk unavailable

When I hover the cursor on disk unavailable the menu shows all details as Unknown.

I posted the issue on Intel support forum but they said they can't help since three have ended support for optane drives.

That's not unusual for the drive to fail that way on those Optane SSDs.

It's not fixable.

I recommend that you replace the Intel Optane SSD with a standard NVMe SSD

You're saying the SSD is gone for sure?

I believe it happened because of a Windows 11 update.

Someone should be held responsible for loss of time and data like that. 

[Paul_Tikkanen]

Yes, that's what I'm saying.

You are the 'someone responsible' for keeping your data backed up.

I do monthly backups of all of my PC's to external hard drives, so when something like that happens, it's not a catastrophe.

It's not a matter of if a drive will fail but a matter of when.

My drive didn't have much important data. Most of it was synced to One Drive.

But from my research it seems Intel Optane SSDs have a way higher failure rate and normal ones. I have never heard of an SSD failing that too suddenly. Even my HDDs have never failed on me. This was a first time and I thought maybe it was a driver issue.
