mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error

I try to mount a disk added to an Azure VM, but it fails with the error message: mount: /mydirectory: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error. Here is what I did: I created a disk and attached it to an Azure VM.  I then ran the command sudo fdisk -l, which gave me this output: Disk /dev/sda: 300 GiB, 322122547200 bytes, 629145600 sectors Disk model: Virtual Disk Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Then, I called the command sudo fdisk /dev/sda with these steps Welcome to fdisk (util-linux 2.34). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0xeacbff1b. Command (m for help): n Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p): p Partition number (1-4, default 1): 1 First sector (2048-629145599, default 2048): Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-629145599, default 629145599): Created a new partition 1 of type 'Linux' and of size 300 GiB. Command (m for help): w The partition table has been altered. Calling ioctl() to re-read partition table. Syncing disks. After the fdisk call I tried to mount it (sudo mount /dev/sda1 /mydirectory) but it failed with the error message above: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error. How can I solve this problem?
