People might be keeping crucial documents on their NVMe M.2's that's why I had to forewarn in the title.
I had updated to 4004 for 2 days now and was getting no errors whatsoever.
After Call of Duty Warzone crashed, I wanted to reboot which I did via a normal procedure and when the OS reloaded, my drive E: which was on a PNY CS2130 NVMe M.2 was nowhere to be found.
- Disk Management did not see it.
- BIOS did not see it.
- Clearing CMOS did not do the trick.
- Enabling/disabling NVMe Raid Mode did not work.
It had vanished without a trace after a simple restart.
As a last resort, I downgraded to 3801- a seemingly celebrated BIOS version for its stability - and it was all over back to normal again.
I know it might be anything - my NVMe M.2, my motherboard or other components. However since downgrading DID work, I thought you might want to know and keep a backup of your important files just in case or go back to a former BIOS like me before making sure this latest one is rock solid.
