Whats the difference between Delete and Delete And Secure Erase?
Use Delete to remove a partition from a hard disk. The data in the partition will keep on residing on the hard disk, it can only be made accessible by the Undelete partition tool (e.g. Partition Table Doctor). If you prefer to remove a partition from a hard disk and destroy all the data, you can use the Delete and Secure Erase option. Once a partition has been securely erased, it cannot be brought back by using the Undelete partition tool.
