• It is theoretically impossible to guarantee the secure wipe of a floppy diskette, hard disk drive or tape using a software solution.

• Some data may still remain behind after a data scrub for discovery.

• Specialized and very expensive equipment is not required to reliably recover shadow data.

• Reliability of some methods and techniques produce evidence grade results from a computer forensics standpoint.

• The use of basic data recovery tools and techniques can be compared with the tools and techniques used by US government agencies in the identification and extraction of shadow data.

• Newer hard disk drive technologies, however, make recovery of shadow data a bit less fruitful.

• Today’s hard disk drive technology does, however, limit the potentials of security risks tied to shadow data somewhat.

7. Преобразуйте следующие предложения в вопроси- гкльную и отрицательную форму:

• When the paint is sprayed onto the road, some of it may seep downward into the pours asphalt that makes up the surface of the road.

• If we were to slice off layers of the asphalt, the original painted line, in some places, will be overlapped with the new color.

• It is theoretically impossible to guarantee the secure wipe of a floppy diskette, hard disk drive or tape using a software solution.

• You should be aware, however, that the recovery of shadow data is no easy task.

• From a computer forensics standpoint, shadow data has yet to become a source of reliable computer evidence.

• As an additional note, older encoding methods, e.g., MFM and RLL, make the recovery of shadow data a bit less difficulty.
