In linux, all disk drives are known as "block devices" because they work with blocks of data. In C++ and Java you will access files using either input/output streams or random access.

In order to get your filesystems mounted automatically, you may need to edit your /etc/fstab file. For more info, you can type this the terminal:

man fstab
