• Use the NTFS file system to format partitions
• Use the FAT file system to format partitions

This articleArticleThis section describes the differences between quick formatting and regular formatting.

Answer: When you choose to run regular formatting on a volume, the file will be removed from the volume being formatted, and the system will scan the hard disk to check whether there are bad sectors. Scanning bad slice takes most of the time to format the volume.
If you select quick formatting, the system will only remove files from the partition without scanning the disk to check whether there are bad sectors. This option can be used only when the hard disk has been formatted before and it can be ensured that your hard disk is not damaged.
If you install Windows XP on a partition formatted using the quick format option, you can also check your hard disk by running the chkdsk/R command after Windows XP is installed.
