If you’re only going use it on Windows computer, then go with NTFS partition…

Formatting a disk is not a completely secure way of wiping all of its data… A formatted disk will not appear to have files on it, but it is still possible that special recovery software could retrieve the files.

If you need to securely delete the files, you will need to use a command-line utility, such as shred.

When you ready to format external drives on Ubuntu desktop, continue below:

Option 1: Use Ubuntu Disk App (GUI)

First step is to insert or plug the disk to your Ubuntu machine… After that, open the Activities Overview and search for Disk

When the disk app opens.. select the disk you wish to format…

Make sure that you have selected the correct disk! If you choose the wrong disk, all of the files on the other disk will be deleted!

Option 2: Using Ubuntu Command Line

As above, you can use the command line to accomplish the same…

When the disk is in, run the command below to print or show attached block devices…

lsblk

That should output similar lines as shown below:

Output:
.............
loop14   7:14   0  42.8M  1 loop /snap/gtk-common-themes/1313
loop15   7:15   0  34.6M  1 loop /snap/gtk-common-themes/818
loop16   7:16   0   956K  1 loop /snap/gnome-logs/73
loop17   7:17   0     4M  1 loop /snap/gnome-calculator/406
sda      8:0    0  30.4G  0 disk 
└─sda1   8:1    0  30.4G  0 part /
sdb      8:16   0    10G  0 disk /media/richard/Private
sr0     11:0    1  1024M  0 rom  

The highlighted line show the disk I inserted and where it’s mounted…

Again, formatting a disk will wipe the disk of all content… so you must be sure you want to format and want to format the correct disk…

Now that you know where the disk is named and where’s it’s mounted, run the commands below to format and erase the disk…

sudo dd if=/dev/zero of=/dev/sdb bs=4096 status=progress

Depending on the size and speed of your computer, this could take some time… When the process is done, you should see similar lines as below:

10712887296 bytes (11 GB, 10 GiB) copied, 11 s, 974 MB/s
dd: error writing '/dev/sdb': No space left on device
2621441+0 records in
2621440+0 records out
10737418240 bytes (11 GB, 10 GiB) copied, 11.0205 s, 974 MB/s

After that,  you can begin for format with appropriate partition table..

To use the disk everywhere, you’ll want to format with FAT32 filesystem… These are the common filesystems on Windows: exFAT and NTFS

Run the commands below to create a msdos (FAT32) table on the disk..

sudo parted /dev/sdb --script -- mklabel msdos

Then create a FAT32 partition tables on the entire disk

sudo parted /dev/sdb --script -- mkpart primary fat32 1MiB 100%

Finally, format the disk with Fat32

sudo mkfs.vfat -F32 /dev/sdb1

That’s it! This is how one formats external drive on Ubuntu Linux.
