The iPhone does not have a hard drive. It has a flash drive or flash storage.
If you wipe the entire flash drive, everything will be deleted except for the firmware/OS and all included apps.
You can erase all content and settings direct on the iPhone at Settings > General > Reset, which is a secure erase, or you can restore your iPhone with iTunes as a new iPhone or not from your iPhone's backup which is not a secure erase of all data and settings.
