User manual ONTRACK DATAERASER PROFESSIONAL V2

[. . . ] Options to erase (overwrite) a single partition, or all areas of a hard drive are provided as choices in a simple menu system. DataEraser writes predetermined character patterns (the final pattern is a selection choice in some cases) to the surface of the hard drive. When a pattern (any character or combination of characters) is written to a data area, any previous information is lost so far as any operating system can access. If the full drive option is chosen, all data in normal file areas, hidden files, or protected areas will be erased. [. . . ] See Errors and known limitations section later in this manual if not all hard drives are shown. 8 Copyright © 2000 ONTRACK Data International, Inc.
