Why is it insufficient to format or delete partitions containing files with confidential data?
Formatting of a hard disk partition does not affect the data written on the sectors of a hard disk in any way. Formatting just creates the data storage structure on a disk, this is known as a file system. If you just format a hard disk drive partition, only the names of files registered in the File Allocation Table will be destroyed your confidential data will remain in sectors of the hard disk.Partitions existing on a disk are described in the Partition Table of the hard disk. Simple deleting a partition only makes the sectors of that partition to be considered unallocated. Files and data structures of the deleted partition remain intact.
