[SOLVED] [False alarm] How to recognize a microSD from a usb reader?

bestfriend · 2023-04-09 22:06:28

The usb reader itself shows up, but I get little information from lsblk and nothing from blkid.

>blkid
(nothing relevant here)

I'm unsure how to mount the actual microSD card. Any leads to follow? I didn't find a nice lead from searching the wiki.

I've tried two different USB SD card readers with different microSD cards, and both act this way. I'm on 6.2.9-arch1-1.

If it's relevant, the other SD card reader is registering as

What file system is on the microSD card? fdisk or parted will tell you that. Mount the file system to somewhere.

Thanks for the reply.

I think I found the issue: the two microSD cards I tested this with are both dead! I tried a third and fourth card, and those two work. False alarm!
