  1. sudo mount /dev/sda7 /mnt

  2. sudo badblocks -o badblocks.txt /dev/sda7

  3. sudo mke2fs -l badblocks.txt -n /dev/sda7
    /dev/sda7 is apparently in use by the system; will not make a filesystem here!

sudo mount /dev/sda7 /mnt
mount: /mnt: unknown filesystem type ‘LVM2_member’.

??? what ? how ?

Hi, not familiar with badblocks or any errors related to that, but from what you write it seems like you’re trying to mount a logical volume, rather than the filesystem contained within it. The actual filesystem will be under /dev/mapper/....

Could you run

lsblk

from your livesystem and post here what it says?

Hey, thanks & sorry for taking so long to reply.

So your sda7 is indeed part of a logical volume group (as it should be, this is the default for Fedora) and your actual root/home/swap filesystems are fedora-....

You’ll find them under /dev/mapper, so the commands you’re looking for are

fsck /dev/mapper/fedora-home

to check the home filesystem and

mount /dev/mapper/fedora-home /mnt

to mount it to /mnt.

You can’t make/test an ext filesystem on /dev/sda7 because it is not the partition the filesystem resides on. Basically, all your mke2fs/fsck/badblocks commands need to be run on /dev/mapper/fedora-home and/or /dev/mapper/fedora-root rather than /dev/sda7.

Actually, both mke2fs/mkfs.ext4 and e2fsck/fsck can deal with invoking badblocks for you, so if you want to find & mark bad blocks on your existing filesystem, you can run

sudo fsck -vcck /dev/mapper/fedora-home

(this will keep your data intact).
If you want to create a new filesystem with bad blocks marked, you can run

sudo mkfs.ext4 -cc /dev/mapper/fedora-home

(this will destroy your data).

Hope this helps.
