Free space bleaching

Deleting an asset in Windows does not completely remove the contents of the asset from your hard

drive. Windows only deletes the reference to the asset. The content of the asset still remains on the

hard drive until another asset overwrites that same area on the hard drive with new information.

Free space bleaching allows you to securely write random data over deleted assets, preventing users

from viewing the original contents of the deleted asset.

NOTE:

Free space bleaching is for those assets that you delete using the Windows Recycle Bin or

when you manually delete an asset. Free space bleaching provides no additional security to shredded

assets.

You can set an automatic free space bleaching schedule or you can manually activate free space

bleaching using the

HP ProtectTools

icon in the notification area, at the far right of the taskbar. For

more information, refer to
