I use USB flash drives and 480 GB SanDisk portable drives for some

day I tried to boot the computer, but found that the computer hung.
Only at this point did I find out that those drives are not capable of
journalling.
I use USB flash drives with ext4 for backups and have not had any
problems with journalling. I have had at least one successful journal
recovery, after an inadvertent disconnection before unmount. What
problems did you encounter?
I optimised my ext4 backup filesystems for a small number of large files
(compressed archives) with:
mkfs.ext4 -J size=4 -m 0 -T largefile4 -O "^resize_inode" /dev/sdb1
tune2fs -c 0 -i 0 -L Backup /dev/sdb1
My /etc/fstab contains:
LABEL=Backup /media/backup ext4 noatime,noauto,user,errors=remount-ro 0 0
Kind regards,
