When a partition of the HDD is deleted, only its partition table entry is removed from a table; and the data on that hard disk partition is not accessible, but the data still remains on the hard disk drive until being overwritten. Some specialized recovery software can locate deleted filesystems and restore a partition table which contains entries for these deleted filesystems. Though, some hard disk utilities software may also overwrite many of sectors of a partition beginning they delete. Like, if Windows Disk Management is used to delete a hard disk partition, it will overwrite the first sector of the hard disk partition before removing it. Availability of the boot sector may restore a FAT32 or NTFS hard disk partition.
