Description Control
During execution of a DoD disk wipe, GDisk attempts to detect an
HPA/PARTIES area on the disk. If an HPA/PARTIES area is
detected, then you are asked if this area is to be wiped. If the area
is not password protected, then the area is wiped. In all cases, you
are informed of the success or failure of the wipe. Wiping Host Protected
Area (HPA) PARTIES
GDisk provides the view:n command to view the overwrite pattern
on the disk to confirm the overwrite has occurred by sampling.
You can use the view:n command-line switch to display one or
more sectors, starting at n, of a physical disk on stdout (by default,
1 sector is displayed). Sector numbers start at 0.
Each sector is displayed as a table with 16 columns containing the
sector offset, then hex bytes, and lastly 16 ASCII characters
representing each byte. This table has n rows, where n depends
on the sector size and is usually 32 rows (sector size of 512 bytes).
