Explanation

The key difference between a quick format and a full format is bad sector scanning: a quick format only erases the file system metadata (the master file table/directory structure), making the drive appear empty without actually wiping data. A full format does everything a quick format does PLUS performs a read/write pass across the entire disk to scan for and map out bad sectors. This makes a full format significantly slower (especially on large drives) but more thorough for drive health verification. The other options are incorrect: both formats prompt for confirmation in most OS dialogs; neither format affects all partitions simultaneously by default; and quick format does not selectively target only the system partition.
