    Hello,

    I've had my external HD for around for around 4 hours now and it's started grinding and making strange noises so I'm returning for a replacement. However, I already have hundreds of family photos and work documents on their that I want to erase (Securely)

    I've used KillDisk on a Windows machine once before. How can I securely wipe all traces of data from it on my Mac before exchanging it?

    Many thanks

    haha brilliant, thanks for that. I'm fairly new to Mac's tools/utilities so I wasnt sure if I needed a 3rd party app. Will simply zero-ing out the disk with one pass of 0's be enough to wipe my pictures and documents from retrieval.

    (not that I expect anyone to try.. but I'm a bit paranoid about identity theft these days)
