Bottom line is that data can be retrieved almost no matter what if someone has the patience and the money. Something that utterly destroys the drive is the only true way to kill it such as drive shredding/grinding; most document shredding companies will do this. There is also thermite
 However in the defense of the software solutions... most of the multi pass systems will deter any average person just not the government or corporation with deep pockets that can afford a magnetiscope and tons of labor. If you are worried about the multipass solution not being enough then first wipe the drive with a multipass wiping software, then remote the controller board from the drive. Throw them away at seperate times. Now if the drive is retrieved not only is the drive wiped and written over several times but the rom that stores the platter mapping is also gone and there is no way to exactly link up the revision of the controller board that can retrieve that info if they drive writes some of the info to the platters. There is a great couple of videos on youtube about data recovery that explains how modern hard drives work, etc. Here is a link to one http://www.youtube.com/watch?v=vCapEFNZAJ0 |

Avoid selling the old Hard Drive with old system; keep it or destroy it completely by any means.

By placing 0101010 over the files, they'll no longer have any sort of access into it. Too bad you can't do manually. -------------------- Who said I couldn't have everything?

There are so many data recovery software which can successfully retrieve data from a formatted hard disk- it will even tell you how many times this particular disk has been formatted.So I think it is not true that reformatting a hard disk completely erase data on it. -------------------- Victory of Mind over Matter

The more I read the replies I'M leaning to the hammer like Swordie mentioned.Reformating only gets rid of the normal way to access the H.D. information. The information is still there and can be retrieved or written over. Retrieving would take a special program and skills.

One pass of zeros will keep anybody but the CIA (for example) from EVER recovering your data and, if you then use the restore CD's to put the system back in its "as delivered" state, you can give it to somebody or sell it.

Er... If they're hackers, they can easily retrieve that file. What a Recovery does is simply place the files in the "Recycle Bin" but it never "deletes" it. -------------------- Who said I couldn't have everything?
