Answer:
There are two types of formatting the IDE devices must go through:
- Quick Formatting
- Full Formatting
Step-by-step explanation:
Quick Formatting only writes the blocks that contain the file system structure while Full Formatting access each sector on the disk and write zeros to all data sectors. that is the reason why Full Formatting takes more time.
One reason you might want to do Full Formatting is when you want to give away your disk. In this case, Full Formatting will access each sector and erase the data completely.
