Recover data from Intel Optane H10 — Spectre x360 won't boot, volume won't assemble

[mathiasamk]

My HP Spectre x360 15-eb0018no (i7-10750H) hangs on the HP logo and won't boot Windows. It uses an Intel Optane H10 hybrid drive (model HBRPEKNX0203AH — 953GB QLC NAND + 27GB Optane cache). HP hardware diagnostics PASS on both chips, so the hardware seems healthy.

Booting a Linux live USB, both chips appear (nvme0n1 = 953GB NAND, nvme1n1 = 27GB Optane). mdadm --examine shows intact Intel ISM RAID metadata with correct checksums and 'clean/normal' state on both the Data Volume and Cache Volume — but with Attributes: 83000001 (not supported), so the cached volume won't auto-assemble and the main NTFS C: partition can't be mounted.

My goal is just to recover two folders (Desktop and Documents) before any repair. Has anyone successfully reassembled an H10 caching volume outside Windows, or is there an HP-specific tool/BIOS step to make the data partition readable again without wiping it? I have NOT run any destructive commands and want to keep it that way.

I assume you tried to run windows Safe Mode and were unable to repair the problem and data recovery is critical.

Remove the drive and attach it to a USB adapter.  Use another pc to access the drive.  You may need the bitlocker recovery key and an application to read the drive.

I have used File Scavenger.  It is free to download and will tell you if it can recover the files.  If it can recover then you need to buy the license.

The app cannot be installed on any drive that you want to recover files from.
I keep it on a separate computer and attach the problem drive using USB3
It can recover data from a formatted drive. Cannot recover from a 'wiped' drive.
select * or whatever files you are looking for such as *.docx in the 'look for'
Set your USB drive in the 'Look in'. You may need to do a long search if FAT is corrupted

The following image shows the list of file that File Scavenger can recover
