I have an empty disk mounted as /data
The df -h shows me that 188M are used while a du -h shows me 4,0K.
root@marc:~# du -h --max-depth=1 /data
4,0K /data
root@marc:~# df -h

/dev/sda1 230G 188M 218G 1% /data
I was planning to reformat the disk in order to install a new system on it but I would like to know what these 188M are.
The /dev/sda1 is formated as ext4 partition. Could this be ext4 specific information I can safely erase ?
