Quick Format VS Default Format

When you ready to format you partitions, you have two methods to format a partition, you can work with default formatting and other quick format method.
When you first time format your system partition, you should use default method. This is slow and low-level formatting but with this method you can remove all data from the partition as well as the hard disk is scanned for bad sectors. Here you can fix your system bad sectors.
If you select the quick format method, you can save time but you can remove only data from the partition and does not scan the disk for bad sectors. If you sure about your hard disk health then quick format should be fine to remove data with in short time.
