[SOLVED] can't write on new SSD

Hi,
I tried adding another SSD to my system for additional storage. I partitioned it, mounted it and added it to my fstab file. I can see it in Dolphin (I'm using Plasma) but I can't write any data on it.

I'd be grateful for any help

In case it's necessary:
Here's my partitioning scheme:

 Disk /dev/sda: 1.82 TiB, 2000398934016 bytes, 3907029168 sectors
Disk model: Samsung SSD 870 
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: D30FB91E-8718-8F47-8253-9261EA2502EC

Device     Start        End    Sectors  Size Type
/dev/sda1   2048 3907028991 3907026944  1.8T Linux filesystem

Disk /dev/nvme0n1: 232.89 GiB, 250059350016 bytes, 488397168 sectors
Disk model: WDS250G3X0C-00SJG0                      
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 8EF790A5-A9BC-8C41-8452-A94766E42DAB

Device           Start       End   Sectors   Size Type
/dev/nvme0n1p1    2048   1128447   1126400   550M EFI System
/dev/nvme0n1p2 1128448 488396799 487268352 232.3G Linux filesystem

and my fstab file

# Static information about the filesystems.
# See fstab(5) for details.

# /dev/sda1

Re: [SOLVED] can't write on new SSD

stat /home/"your user"/extra

Hint: it's ext4, that's a real file system w/ real permission handling and it doesn't matter where you mount it or who owns the mountpoint: if you've no writing rights on the root of the filesystem, you're not writing there.

=> man chmod/chown

Re: [SOLVED] can't write on new SSD

So the commands

chown "my user" /home/"my user"/extra

and

chmod g=rwx /home/"my user"/extra

would both do the trick here? Did I get this right?
