Access my second harddrive

Your problem

So you have installed Manjaro and you realize that your second disk is not writeable. You can access the data but you cannot change it.

The primary cause is permissions and those can be solved by this guide.

However the issue could also arise when you dualboot with Windows, and the partition you want to access is the Windows root partition.

NTFS partition

If your disk is a Windows disk - it can be as simple as

  • Restart your system and load Windows.
  • Disable features like Fastboot, hibernation and hybrid sleep.
  • Run a disk check and fix any errors

Create a mountpoint

Locate the device and partition(s).

$ lsblk
sda      8:0    0 223,6G  0 disk 
├─sda1   8:1    0   512M  0 part 
├─sda2   8:2    0    60G  0 part 
├─sda3   8:3    0   130G  0 part 
└─sda4   8:4    0  33,1G  0 part [SWAP]
sdb      8:16   0   477G  0 disk 
└─sdb1   8:17   0 419,1G

Make a permanent mountpoint.

Create a folder for the purpose (change all references to mydisk as you would want a more descriptive name).

sudo mkdir -p /data/mydisk

Mount the partition

Replace the yX with the device and the partition number you found.

$ sudo mount /dev/sdyX /data/mydisk

Set owner

Recursive change owner on the folder structure. Manjaro uses a group with the same name as the user which you can verify with:

$ groups
sys lp wheel network video optical storage scanner power $USER
$ sudo chown -R $USER:$USER /data/mydisk

Creating a permanent mountpoint for a partition

Folders are locked, can access to them but can't delete permanently
