256GB Expansion card not recognised

Hello, I’m getting ready to install Linux on an expansion card but the card isn’t detexted as a drive on which to install the OS. And when I check out the expansion card’s properties, it shows a total capacity of 3.87MB (my expansion card is actually 250GB). Does anyone know why that is?

It’s been a while since I’ve done this so I may be wrong, but it could be the way you formatted it. It may not like FAT.

It might be better to do this using a dedicated installer like Rufus or Etcher. I think you can enable persistence with these, which will turn the live USB into one in which you can save files and install programs.

I’ll delete this if I’m wrong.

Thank you @anon81945988 and @Fraoch

Weirdly, this is what I’m seeing when I look at Disk Management:

It looks like the Expansion Card is partitioned into a 4MB partition and the rest is separated (Disk 1 partition 2). Does it mean I should delete that second one?

It’s only seeing the smallest partition. Strange!

I’d blow it all away and let Rufus handle formatting the entire drive.
