Where is the Wipe function?

I have a version I must have bought in 2014 to recover some files. I want to deep-wipe old SATA drives. I formatted the drive in Windows but I want it deeply erased. Suggestions?

Recurva version is v1.51.1063 (64 bit)

Yes, use the free CCleaner Drive Wiper function, as indeed you are discussing in your other post.
