Unused disk space: Cipher vs. Eraser



Hello there,

I have noticed, that the never versions of Windows have an updated version of Cipher.exe with the possibility to erase unused disk space.
I have tested Eraser and Cipher.

The result:

Eraser: The recovery tool was not able to find any of my deleted files.
Cipher: Recovery tools seems still to be able to find my deleted data with the exact file names. But the content of that files itself is destroyed and useless.

Could someone explain this please?
Does Cipher not delete the file names or what is the reason for that phenomenon?

I am guessing that Cipher.exe is only wiping the free space and not the MFT.

Eraser does both and with ISAAC, hopefully soon to be with ISAAC+ in V6.
