■ If your hard disk or other storage media contains sensitive data, you
should be aware that standard deletion procedures do not remove data
from the media. These standard deletion procedures include:
■ Selecting Delete for a target file.
■ Putting files in the Recycle Bin and emptying the Recycle Bin.
■ Reformatting the media.
■ Reinstalling an operating system from the recovery CD-ROM.
The procedures above delete only the initial part of the data used for file
management. This makes the file invisible to the operating system, but
the data can still be read by specialized utilities. If you dispose of the
PC, please delete all the data on its hard disk drive. Doing so prevents
unauthorized use of such data. To ensure your data is not used for
unauthorized purposes, you can:
■ Physically destroy the hard disk drive.
■ Use a proven specialized utility to overwrite all data.
■ Take the hard disk drive to a professional deletion service.
