Make a HDD safe for resale?

i have a few HDDs kicking around that are worth selling but not worth keeping

i am not sure what i need to do to completely erase all the data, i used to think you just had to wipe the data via format a few times and rewrite but found this isnt even enough sometimes cause of cluster being partially filled

i found that a utility called 'eraser' is free and writes random data to a disk wiping it completely and can go through as amny writes/formats as you choose

is this enough to then sell them?

I don't understand this statement...
"i have a few HDDs kicking around that are worth selling but not worth keeping"

If they are good enough to sell, then surely it follows they are good enough to keep? You could use them as back-up drive or for general storage.

Dban can wipe a drive to high level - but three random passes are more than adequate! link click here

Yes, that'll do just fine. The 3-pass option is more than enough. G

I see your reasoning, however looking at it logically...
...it would be better to keep 1 egg in many smaller baskets, than many eggs in one big one.

The size of the HDD doesn't make it any safer or less prone to packing up, as I can testify! I successively lost all my work once, then potentially lost it on two more occasions. Because the HDD's went belly up, without warning!

But after the first time, I wised up and I now spread the load. I keep it all on many disks. So when I had two more HDD's go down, I could smile at my good fortune and foreword thinking.

It makes me shudder when I see all these bigger and bigger drives, now it's Tbyte, I see it as terror byte. When I think of all those people putting everything on one massive drive.
