microSD card not recognised by lsblk, errors in dmesg

admin

I got a new Kingston 1Tb microSD card and made the mistake of putting it into my Steam deck right off rather than formatting it on my laptop first. The Steam deck format got stuck on “testing” and even though I shut down the device before removing the card, it’s now corrupted.

On my Pop!OS laptop, I tried a bunch of things recommended in similar question posts:

  • It doesn’t show up in the list when I run lsblk
  • running dmesg gives the following errors when I plug in my USB SD card reader (I’ve used this reader with other microSD cards fine):

  • Because lsblk doesn’t give me the device name, I can’t use dd or similar recommendations.
  • It doesn’t show up in Gparted.

Anything I can do to recover/format the SD card? I don’t care about data loss.
