Cannot format my SD card [duplicate]

I am new to Ubuntu, using 14.04 I am trying to format an SD card to make space on it, and it's not working. I tried in terminal:

format mmcblk0
hformat mmcblk0

and it says:

hformat: /home/michael/mmcblk0: error (no such file or directory)

How do you format an SD card?

It's very easy.

1. First insert your SD in Sdcard Reader, let Ubuntu mount it.
   check the access path for the sd card using dfYou will get some output like this

   Filesystem 1K-blocks Used Available Use% Mounted on
   /dev/sda7 104087776 76247376 22529988 78% /
   /dev/sdd1 15549952 13056 15536896 1% /media/g/3630-6335 

2. Unmount the sd using

   sudo umount /path/to/sd/card

3. Format the card using mkfs

   sudo mkfs.vfat -F32 -v /path/to/sd/card

-F flag is for Fat32 system.
-v flag is for being verbose

You can use the included Disks application

Click on the target partition. Now you can create new partitions, format the disk or change partition type.

Use the software gparted to format the partition on your sd drive

1. Download gparted from the software centre

2. Start it

3. Load your sd within the software (upper right button)

4. right click on sd partition: unmount

5. Delete partition

6. Create new partition fat32, label it as you like

That's it, if you have any problem write here :)
