After you create the mount point then we'll add that drive to our `/etc/nixos/configuration.nix':
```
fileSystems."/mnt/ExtraDrive" =
{ device = "/dev/disk/by-uuid/72315f9e-ceda-4152-8e8d-09590affba28";
fsType = "ext4";
};
```
> *NOTE:* You can find the UUID by using the `blkid` command, you will need to use `sudo` or change to the root user.
```
sudo blkid
```
or
```
sudo -i
blkid
```
then rebuild NixOS:
```
sudo nixos-rebuild switch
```
You'll see the following if done correctly:
```
unpacking channels...
building Nix...
building the system configuration...
these 3 derivations will be built:
/nix/store/3ryw7m6gvim8zs593wkibcg143pix7zd-etc-fstab.drv
/nix/store/va8nfw2j4i5jviibqy5cggnmjsjmds2v-etc.drv
/nix/store/hpm2aykvls876qgjrkva2ys3xmn08sri-nixos-system-rpi4-22.11pre405560.2da64a81275.drv
building '/nix/store/3ryw7m6gvim8zs593wkibcg143pix7zd-etc-fstab.drv'...
building '/nix/store/va8nfw2j4i5jviibqy5cggnmjsjmds2v-etc.drv'...
building '/nix/store/hpm2aykvls876qgjrkva2ys3xmn08sri-nixos-system-rpi4-22.11pre405560.2da64a81275.drv'...
stopping the following units: mnt-ExtraDrive.mount
activating the configuration...
setting up /etc...
reloading user units for gdm...
reloading user units for aaronh...
setting up tmpfiles
starting the following units: mnt-ExtraDrive.mount
the following new units were started: systemd-fsck@dev-sda1.service
```
Now we'll see it when we reboot:
```
[aaronh@rpi4:~]$ lsblk

sda 8:0 0 232.9G 0 disk
