I couldn't have said it better myself. Wojciech lives in his own little world, which is fine as long as he doesn't try to visit mine. He sounds like he works at a small Polish SMB, more commonly referred to as a SOHO in more developed countries. I have just blocked him so I don't have to read his TROLLish bullshit. The fact that he mentioned "scandisk" which Microsoft only released in Microsoft Windows Millennium Edition, Microsoft Windows 98 Standard Edition and Microsoft Windows 98 Second Edition makes one wonder just how current he is with modern operating systems and techniques. He obviously has no idea what SpinRite is, how it works or even the concept of directly interfacing with hard-controller disk chips. For him, "dd" is state of the art. -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.
