Disk Wiping – One Pass is Enough

That's a good site. Sadly, it seems to be abandoned, update wise. Last post was in December.

I had problems with the one-pass wipe in Eraser. I was finding file names all the time. I used the 6.0 and earlier versions with the same result. I had used Eraser for many years - back when Sami wrote and maintained the original Eraser. However...

I finally plucked down the money for BCWipe and there's no file names left on a one-pass wipe. All in all, I've found it to be a far superior tool.

I don't recommend one pass if it's involving top secret data. In fact, the best way to wipe data is to smash the hard into pieces.

But I can confirm that the one pass wipe "going to at least 50% progress" (either zero or random) is good to kill the stubborn bootloader remnant structure of an FDE.

 

with fde as in TC? you dont need to erase anything , regular delete command in windows is enough to turn any data into random gibberish that can not be deciphered , no matter how "top secret" your data is considered

p.s: and no smashing isnt the way to go about it unless you deliberately enjoy destroying perfectly clean and functional hardware , might as well nuke it from orbit just to be safe , lols


and yes bcwipe is the only way to go to be sure youve completely obliterated any traces of private data from non fde hdds

 

For top secret info it's wipe + destroy the hardware. It's never been shown that information can be extracted but if you're dealing with nukes it's best to be sure.

Personally I'd just do two wipes in case the software screws up but I think 1 is enough.
