[Discuss] memory stick issue

[gaf.linux at gmail.com (Jerry Feldman)]

I tend to prefer using the GUI Disks utility provided by Fedora.
mkefs should format correctly. USB memory sticks are not good for backup
devices. USB drives are much better, especially if you are using a good
brand.

I took an dos formatted USB,, and here is what I did:
gaf at fedora ~]$  sudo mke2fs -t ext4 -Ltestme /dev/sdf
mke2fs 1.46.5 (30-Dec-2021)
Found a dos partition table in /dev/sdf
Proceed anyway? (y,N) y
Creating filesystem with 238080 4k blocks and 59520 inodes
Filesystem UUID: 77458f09-0dad-4d30-be10-500c6cc38296
Superblock backups stored on blocks:
32768, 98304, 163840, 229376

Allocating group tables: done
Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done

I then removed and plugged the stick back in
the mount command now shows:
/dev/sdf on /run/media/gaf/testme type ext4 (*rw*
,nosuid,nodev,relatime,seclabel,errors=remount-ro,uhelper=udisks2)
[gaf at fedora ~]$ cd /run/media/gaf/testme
