GarudaOS crash and boot issue

[Technetium]

Might have unmounted too early. I’m always worried about that… Maybe watching the writeback cache will help in the future

High single core usage while transferring files

This is correct. Unless you mount with sync. See more from man mount. I usually do not want to mount with sync, so I watch my writeback cache with this to ensure completion: alias watchsync='watch -n 1 -d grep -e Dirty: -e Writeback: /proc/meminfo' @PerseverantX please also include the results of cat /etc/fstab and sudo smartctl --all /dev/sdX, where sdX is the disk in question.
