A friend of mine gave me an SD card, which was in his tablet and spontaneously wasn't recognized by that tablet. Of course, there is no backup.
So I put it into my computer (with an adapter to USB) where it is recognized somehow, but I can't see it in my files, I can't mount it and it doesn't seem any file system is on the SD card.
Images that disk shows me:
- Disk -
/dev/sda
- Disk -
/dev/sdb
I Googled and saw that people used dmesg and fdisk, but I don't know what this should tell me; maybe you can help me somehow?
This is what dmesg gave me when I plugged the SD card in.

Trying to mount them results in this error code and dmesg doesn't show anything:
>$ dmesg > before.log
╰─>$ sudo mount /dev/sda /mnt/
mount: /mnt: no medium found on /dev/sda.
dmesg(1) may have more information after failed mount system call.
╰─>$ sudo mount /dev/sdb /mnt/
mount: /mnt: no medium found on /dev/sdb.
dmesg(1) may have more information after failed mount system call.

lsblk shows this:
╰─>$ lsblk

sda 8:0 1 0B 0 disk
sdb 8:16 1 0B 0 disk
...
And trying to move data with dd results in this:
╰─>$ sudo dd if=/dev/sda of=sda.tmp
dd: failed to open '/dev/sda': No medium found
╰─>$ sudo dd if=/dev/sdb of=sda.tmp
dd: failed to open '/dev/sdb': No medium found
fdisk -l doesn't recognize it at all; it only shows my SSD, and lsusb doesn't show anything when I plug in the SD card.
Is there any way to save the data on the SD card?
