Deleting partitions just marks the partition table as deleted. Nothing is removed or erased.
If it is a SATA disk that you want to wipe it, either use dd or DBAN. DBAN is just a wrapper for dd. Here is an article that talks about wiping: https://www.tecmint.com/permanently-and-securely-delete-files-directories-linux/ If you have an SSD drive, dd is not going to work. You can google for ssd wear leveling for more information. To securely erase an SSD requires the use of the hdparm secure erase utility. NIST 800-88 provides media sanitation guidelines for ssd drives. Cathy -- Cathy L.

Russell, But why didn't deleting all partitions work?
