Demo

Now we can try the whole demo example with the following commands:

1. Create a new file test.disk to hold the virtual drive volume by pre-filling the file with data:

   ~$ dd if=/dev/zero of=test.disk bs=64M count=1
   

2. Next up we give the volume a filesystem. Here, we format it with FAT32:

   ~$ mkfs.vfat -F 32 -f 2 -S 512 -s 1 -R 32 test.disk
   

3. Check the details of the FAT filesystem:

   ~$ dosfsck -v test.disk
   

4. Mount: to mount the formatted file test.disk from the terminal, you will need to first create a folder to mount it to. Let’s say we want to mount it to the folder ~/rd.

** Here is the procedure:

• First create the folder there.

  ~$ mkdir ~/rd
  

• Then mount the file test.disk to the folder ~/rd:

  ~$ sudo mount -t vfat -o loop test.disk ~/rd
  

• Now we can create/copy files to the drive:

  ~$ cd ~/rd
  ~/rd$ ls
  ~/rd$ sudo touch a
  ~/rd$ ls
  

• When we finished, unmount the volume by running this command:

  ~/rd$ cd -
  $ sudo umount ~/rd
  

Here are the results of the demo:
