Deleted NTFS partition to ext4 conversion

  • 772

I have deleted NTFS drive in Windows. After I have added it in Linux I did a quick format to Ext4 (sda9), but it says that 12 GB or (2% of the drive capacity) is used.

Is this normal? Or should I do a full format? Also moving from NTFS to Ext4 is it recommended to do a full format (although quick format seems to be working), does it improves efficiency?

  1. The space is probably taken by reserved blocks, which is usually set to 5%. You can check with tune2fs, assuming /dev/sda1 is the right partition. 

    sudo tune2fs -l /dev/sda1 | grep -i 'block count

    To set the percentage of reserved block to, say, 1%, use the following:

    sudo tune2fs -m 1 /dev/sda1
