Delete file parentally non-recoverable

I would like to be able to do the above ? so that I can sell a external HDD drive.

With the comfort knowing that, whoever buys this cannot retrieve any file through data recovery.

Can anyone help?

aijmexico,
   You can use a third party program the Sure Delete to delete all the files permanently.

I have used Sure Delete before and it works well. PC Magazine recommends it.

Norton WipeInfo, which is part of Norton SystemWorks, has been used by many.

http://dban.sourceforge.net/ <= this program can overwrite all of your harddrives several times so nothing will be recoverable anymore.

As far as I am aware, only the physical destruction of the magnetic media will insure that data is not recoverable. Even if the data has been overwritten several times, I understand that a magnetic force microscopy technique can be used to recover old data. This involves a physical inspection of the disk media by use of some very specialized equipment and highly trained personnel.

Likewise, expensive computer forensic software can possibly retrieve data that has been wiped using software such as those listed above. However, I have seen some such software tested after a wipe using Norton Disk Wipe. The 3 recovery programs used were all unable to recover any data after a government style wipe using Norton WipeInfo. I would therefore recommend Norton WipeInfo, which is bundled in the Norton SystemWorks package - http://www.symantec.com/sabu/sysworks/basic/
