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?

Hi I’ve edited the title as it was vague :slight_smile: and you’ve given no detail of your setup.
Laptop | OS | etc. | How you formatted the 256

Have you already tried to load a Linux OS, which one ? How ?

I have a 256 Expansion card too and did likewise.

So if you have Windows use the Disk Management to see and reformat the whole 256GB

Here’s a link to my effort with Win 10 a couple of years ago on an 1165G7

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 @amoun 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?

I wonder why you have those partitions.

You also don’t show which format.

You can delate all and maybe create 2 partitions 1 for Linux, maybe ext4 and 1 for personal data or /Home as (Fat32 or NTFS)

It’s only seeing the smallest partition. Strange!

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