Disable Journaling and Write Caching on Disk or SSD (Engglish)

DISABLE JOURNALING

Steps to disable journaling:

1. Check if 'has_journal' appears in the features menu using the following command. If it does not appear, it means journaling is already disabled:

sudo tune2fs -l /dev/sdX | grep features

2. Disable journaling by unmounting the partition first, then proceed with disabling journaling. If not unmounted, an error will occur as follows:

- umount

sudo umount /dev/sdX

sudo umount /path/disk

- disable journal

sudo tune2fs -O ^has_journal /dev/sdX

Note: Replace /dev/sdX with the partition to be disabled, for example, /dev/sda1 or /dev/sda2.

3. Verify successful disabling (has_journal does not appear).

1. Unmount the target partition first.

2. To disable, execute the following command:

- disable

hdparm -W 0 /dev/sdX

- enable

hdparm -W 1 /dev/sdX

3. Verification
