There are times that after formatting/reformatting a partition or a drive, you will find that you are not allowed to change of write anything on them. This is because the Permissions are being restricted to the root (admin) user only but not you.
If you are using Dolphin as your file manager, you can easily check this out as follows:
Dolphin --> Right click on the partition/drive (Backup2, in my case) --> Properties --> Permissions, the following window will appear:
From the above, under the row Ownership, you can see that the Permissions are given to root (admin) but not you as an ordinary user.
To change the Permissions from root to user (you), we may use the chown command as follows.
First, find out where the partition/drive, say Backup2, is mounted.
Dolphin --> Click on Backup2 --> Select Properties:
The following window will pop up:
It shows that the Backup2 is mounted on: /run/media/ka/Baclup2. Where ka is the user name.
Now you can use the following command line to change the Permissions from root to user (ka)
sudo chown ka:ka -R /run/media/ka/Backup2
After entering the password, the job will be done!
Let’s check it out:
Dolphin --> Backup2 --> Properties --> Permissions :
Clearly now the Permissions are given to ka (user), and ka can then change or write whatever on the drive, Backup2.
If the deive (or partition) is an NVME Partition or an NVME SSD (e.g., my Backup1), we will have the following:
The mount position is /run/media/ka/Backup1, then the corresponding command line would be:
sudo chown ka:ka -R /run/media/ka/Backup1
Remarks:
chown stands for "change owner", it is a command used to change the owner and/or group of files or directories.
chown -R : change ownership recursively for
Syntax
sudo chown [user entry]:[group entry] -R partition/drive mount point
[user entry]:[group entry] can be root:root, ka:ka, root:ka, or ka:root, depending on the permissions you wish to give the group and yourself.
