Not really. HDD recoverability is a myth, anything overwritten isn't coming back with modern HDDs. Bits can't "bleed out" anymore, density is far too high for that.
The thing you need to guard against is relocated/reserve sectors, in HDDs same as in SSDs. The proper way to do this is full disk encryption, and if that's not possible, physical destruction.
