+backup of "auto mount drive in ubuntu server 22.04" by vineet choudhary. original post is [here](https://developerinsider.co/auto-mount-drive-in-ubuntu-server-22-04-at-startup/)
+
+---
+
+When we connect an external drive, by default, Linux OS (or Ubuntu Server) doesn't automount the external drive at startup. We can mount it very easily using the `mount` command but we want to enable automount feature on startup. So, we don't need to mount the drive again after restarting or logging into Linux OS. Here are steps to auto mount drive at startup -
+
+## 1. Create the Mount Point
+
+First, we need to create a directory which will be our mount point for a drive
+
+```
+sudo mkdir /media/USB1
+```
+
+## 2. Get Drive UUID and Type
+
+Now, we need to get the drive UUID and File System Type. This information we need in the next step. So, to find the drive's UUID and File System Type, run the following command -
+
+```
+lsblk -o NAME,FSTYPE,UUID,MOUNTPOINTS
+```
+
+This will return something like what we have below. Here you can see, sd2 is type exfat and doesn't have any mount point. So, we need to mount this sda2 on `/media/USB1`. There UUID for this is `632D-7154` and File System Type is `exfat`. So, Copy the UUID and File System Type from the disk.
+
+```
+NAME   FSTYPE   UUID                                 MOUNTPOINTS
+sda                                                  
+├─sda1 vfat     67E3-17ED                            
+└─sda2 exfat    632D-7154
+sdb                                                  
+├─sdb1 vfat     D7E2-9D99                            /boot/firmware
+└─sdb2 ext4     b09bb4c8-de4d-4ce6-a93f-30c4c9241a58 /
+```
+
+## 3. Edit fstab
+
+To edit the fstab file run the following command (note I'm using nano here but use whatever editor you prefer)
+
+```
+sudo nano /etc/fstab
+```
+
+You'll see something like this -
+
+```
+LABEL=writable  /       ext4    discard,errors=remount-ro       0 1
+LABEL=system-boot       /boot/firmware  vfat    defaults        0       1
+```
+
+Here we need to add one more entry for our drive. The format for adding a new entry is something like this -
+
+```
+<file system> <mount point>   <type>  <options>       <dump>  <pass>
+UUID=<UUID> <PATH_TO_MOUNT> <DRIVE_TYPE>  defaults        0       0
+```
+
+So, here is the entry for our drive
+
+```
+# USB1
+UUID=632D-7154 /media/USB1   exfat    defaults        0       0
+```
+
+## 4. Test fstab
+
+Now we'll test the `fstab` before rebooting because an invalid `fstab` can render a disk unbootable. So, for the test, run the following command and check if there is any error or warnings. Do not reboot your Ubuntu Server / Linux OS without resolving those errors or warnings (if any).
+
+```
+sudo findmnt --verify
+```
+
+## 5. Restart Ubuntu Server / Linux OS
+
+If the last step doesn't show any error or warnings then restart Ubuntu Server / Linux OS using the following command -
+
+```
+sudo reboot
+```
+
+## 6. Test the Mount Point
+
+Run the same command which we run in Step 2 to check if our drive is mounted to its mount point.
+
+```
+lsblk -o NAME,FSTYPE,UUID,MOUNTPOINTS
+```
+
+```
+NAME   FSTYPE   UUID                                 MOUNTPOINTS
+sda                                                  
+├─sda1 vfat     67E3-17ED                            
+└─sda2 exfat    632D-7154                            /media/USB1
+sdb                                                  
+├─sdb1 vfat     D7E2-9D99                            /boot/firmware
+└─sdb2 ext4     b09bb4c8-de4d-4ce6-a93f-30c4c9241a58 /
+```
+
+Here you can see, `sda2` is now mounted to `/media/USB1`.
