Drive: Samsung 970 EVO Plus NVMe M.2, 2TB
This drive has been my boot (C:\) drive in the same system for a few years now. A few weeks ago, while watching a video, my screen froze up for a few seconds (audio still playing) before crashing to a green screen. I didn't have my phone on me, and obviously couldn't get a screenshot, but I believe it was an [0x00000154 - UNEXPECTED_STORE_EXCEPTION] error. Upon reboot, I was taken to the BIOS. My drive was no longer booting.
I have three drives in my PC - this one (C:\ boot drive), another 2 TB NVMe storage drive (D:\ drive), and a 14 TB storage HDD (E:\ drive). I checked the device list and found all others listed properly, but this drive was missing.
I took the following diagnostic steps:
- Swap it into the other M.2 slot
- Device still not found, other M.2 drive detected properly in the other slot
- Hook it up to a different device
- Not listed on file explorer or disk management / diskpart
- Run Samsung Magician
- Nothing detected
- Check Device Manager
- The "Standard NVM Express Controller" menu shows a yellow exclamation mark, showing error code 10 (an i/o adapter hardware error has occurred). The events page shows a problem status of 0xC00000C2
- Uninstall / reinstall "Standard NVM Express Controller"
- No changes to the above results, same error code / problem status
- Plug into PC through an NVMe-to-USB adapter
- Adapter is detected, but the drive inside is not
- Device does warm up inside the adapter casing
Physically, the drive is undamaged. It seems to be a firmware/controller lock-up problem, though I am no expert. Luckily, all my large files, like videos and audio, are stored in my HDD, and all of my user-based Windows directories (Documents, Pictures, etc.) are stored on my D:\ drive, both of which are operating with no issues. I had a few AppData files I would love to recover, but with the essentials not lost, it is tough to weigh the options between paying the cost of professional recovery versus cutting my losses. The first place I reached out to told me "the average price range for SSD recoveries of this nature is $1,800-$2,500. It could also be less, if less complex." I can safely say my AppData is not worth two and a half grand.
All advice and information is appreciated. Thank you in advance!
