Hi, guys. May I join in the discussion? I have heard many people suggesting using hdd wiping program to permanently 'wash' the hdd until the data was unrecoverable. But questions are - 1. where do we get 'free' disk wiping program from the net? 2. what assurance that it will do a good job using the 'free' disk wiping program as they are compared commerical licensed ones? 3. Without using any hdd wiping s/w, has anyone try this method before and confirmed that they are not able to recover data of the 1st set original set. (ie leaving the 1st original data intact, use ghost image or any other imaging s/w and restore any data image into the hdd. Next, use the fdisk and then re-format the hdd. Now, use any recovery software (any eg) tools and test to see if the recovered data belonging to the currently restored data (ie the imaged data) or the 1st original data? kenneth -----Original Message----- From: Zachary Shay [mailto:zshay () cc gatech edu] Sent: 01 October 2004 03:12 To: Paul Kurczaba Cc: security-basics () securityfocus com Subject: Re: Hard Drive data security Hey Paul, I would copy the data over to whatever you will use next, or simply just a backup cdr/dvd. Then I would use something like `dd` along with /dev/rand or /dev/zero. That may do what you want. Just deleting or formatting the drive will probably leave traces of data that can be recoverable. I am fairly sure that if you delete the data with a format and then rewrite over the data, then you will be safe. Zach Shay On Tue, 28 Sep 2004, Paul Kurczaba wrote:
Hi, I have a question about hard drive data security. The hard drive on
my notebook is failing and Dell is going to replace it. They are going
to take the old one with them. How can I securely remove the data from
the hard drive? Thanks, Paul
