An excellent post, thank you 0x00, I had always wanted more information about the Gutmann thread.I too was a fan of Heidi Eraser back in the day but the point is moot in any case. A detailed forensic analysis of your hard drive may indeed reveal deleted files on an unencrypted file system however using a Full Disk Encryption program like Truecrypt negates this problem entirely as all free space is filled with random "chaff" data.As such I suggest we take the attitude that prevention is better than cure and say to the OP that this shouldn't be an issue as your file system should be encrypted anyway! :)V.
