Cannot mount microSD card

I am trying to mount my micro SD card but it shows write-protected. I have tried disabling using the notch on the adapter. I also ran the following commands:
lsblk -p

/dev/mmcblk0 179:0 0 29.7G 1 disk
├─/dev/mmcblk0p1 179:1 0 43.9M 1 part /media/somnath/boot
└─/dev/mmcblk0p2 179:2 0 29.7G 1 part 

I also tried using fdisk:

somnath@dell:~$ sudo fdisk -l /dev/mmcblk0
Disk /dev/mmcblk0: 29.74 GiB, 31914983424 bytes, 62333952 sectors
Units: sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

/dev/mmcblk0p2 98304 62333951 62235648 29.7G 83 Linux

I tried formatting:

somnath@dell:~$ sudo mkfs.vfat -F32 -v /dev/mmcblk0
mkfs.fat 4.1 (2017-01-24)
mkfs.vfat: unable to open /dev/mmcblk0: Device or resource busy

Here's the output from Disks:
