Add data disk

I'm trying to add a 1TB SSD drive to banky, connected to the mainboard, to use it as a data disk.

I used fdisk -l to list the connected disks. The SSD already appeared there.

I then partitioned this disk with fdisk /dev/sda/ (/dev/sda was the given name for the disk. The exact name for your case can be checked by running fdisk -l). The command for partitioning is n.

Now it's time for formatting. After some reading, apparently the right choice for a linux data disk would to use ext4. But bear in mind this is not compatible with windows and macos. If you have a disk that would like to use across different OS systems, you can pick fat32.

To format, pick the partition (you can find it with lsblk) and use the mkfs command.

Well that was the theory, because it didn't work for me. I ended up using Debian's GUI disk tool. Two clicks and done.

Finally, the disk needs to be mounted. To do so on every boot, you need to add a line like this one to /etc/fstab.

UUID=66d23b74-677d-4122-8e67-4bc88ea03b18     /media/data_disk/   auto    rw,user,auto    0    0

Where the UUID should be one for the disk (you can find it out with blkid or some other of the disk utilities) and the path should exist.
