I have had to use my laptop (WXP) for some very confidential commercial documents which I have now completed.
I have deleted them from the hard drive, but I understrand that that merely knocks the first letter off the filename and that the space taken by the file is not really blank but is treated as such and may ultimately be re-written on.
How can I delete all references to the documents so that a hacker or thief of my laptop cannot restore or retrieve the file.
There used to be a thing called a "Government Wipe" in Norton but I cannot find it on the current version.
I understand that I need to write over all the blank space so that refences to the documents are taken up with other data. I do not want to have to reformat the hard drive.
Administrators can use Cipher.exe to encrypt and decrypt data on drives that use the NTFS file system and to view the encryption status of files and folders from a command prompt. An updated version of the Cipher tool has been released for Windows 2000, and is included with Windows XP. The updated version adds another security option. This new option is the ability to overwrite data that you have deleted so that it cannot be recovered and accessed.
When you delete files or folders, the data is not initially removed from the hard disk. Instead, the space on the disk that was occupied by the deleted data is "deallocated." After it is deallocated, the space is available for use when new data is written to the disk. Until the space is overwritten, it is possible to recover the deleted data by using a low-level disk editor or data-recovery software.
