SOLVED!: Second drive disappeared after Mint reinstall


Solution: There never was a second drive. It must have been a partition that got wiped with the install, but there's only the NVME in there. Sorry, guys. I dig around in my innards very frequently and just thought I was mounting a second drive this entire time. Hooray for backups.

reinstalled Mint and my second drive is absolutely invisible to everything. I can't mount what I can't see. I'm thinking of unplugging it and plugging it back in just because I'm out of ideas.

What could have caused a drive to become invisible after a reinstall?

Edit: Checked bios. All security disabled. Using AHCI and UEFI (tried CSM). I don't really know what these things mean, I just know things were working properly before I reinstalled mint so I'm puzzled why it could be a BIOS issue.

What? I thought Optane was a weird hybrid drive for mostly laptops I'm running a self-built desktop that's over 10 years old with an MSI Mobo. I was just in settings because something else led me to think it might be a BIOS issue, but didn't see any Optane.

But why would go from one-year-ago-Mint to today-Mint trigger any bios issues?

@schipelblorp @Björn Optane is memory that retains it's contents after a power loss. This makes it useful for drive caches since it prevents loss of data if power is lost before cache can be written to media. And Optane drives ARE supported by Linux, they are presented as two devices the memory and the physical drive rather than as a unified drive as in Windows.

I'm not seeing any image attachments in case you added that.

Some brand of NVME SSDs are the only thing I've seen live driver issues on where the disk appeared invisible until drivers were installed, in one case the pre-installed Intel SSD drivers had to be disabled too because they were incorrectly taking priority.
