Is there anyway I can use wipe disk feature so that I can dispose my HDDs?

Have you ever considered the ethical implications of disposing of your HDDs without properly wiping them clean of personal data? What steps can be taken to ensure that your sensitive information is not accessible to others after disposing of your hard drives?

Please use Disk menu -> Surface test -> Reinitialise Disk Surface test.
This performs industry/government standard data destruction: clears all sectors on any drive (hard disk, SSD, pendrive, memory card etc.) including all user files, unused area, unpartitioned space, foreign (Linux / MAC) partitions and so.
