I have been trying to create an SDcard to use with an Raspberry Pi. The card is created using the rpi-imager program on Fedora (41) and that program reports the creation as successful. Later, after mounting the ext4 partition on the card under Fedora and doing two or three minutes of exploration, I encounter a bad block. So I unmount the partition and use e2fsck to locate any bad blocks and mark them:
e2fsck -y -c /dev/sdb2

Is there any output? Maybe don't use the `-y` option for now.
The only output was a statement that no bad blocks were found.

Throw the old SDcard away, and use a new one.
I intend to. But this isn't a problem with the card.
