disk 1.

gdisk 1 /del /p:2 /qwipe wipes partition 2 on disk 1 with one pass.
■
gdisk 1 /diskwipe /customwipe:15 wipes the entire disk with 15 passes.
Wiping Host Protected Areas (HPA)/PARTIES
During execution of a DoD disk wipe, GDisk attempts to detect an HPA/PARTIES
area on the disk.
Note: This functionality operates with GDisk.exe only. It does not apply to
GDisk32.exe.
The sequence of the wipe is as follows:
■
If GDisk detects such an area, then it shall notify the user that it was found
and ask the user whether this area should be unlocked so that it can be erased.
■
If the user requests that the area be unlocked, then GDisk will attempt to
unlock the area. Otherwise, GDisk continues, ignoring the HPA area.
■
If the area is not password-protected and is successfully unlocked, then GDisk
notifies the user and erases the entire disk, including the HPA/PARTIES area.
■
If the area is password-protected and cannot be unlocked, then it notifies the
user that the unlock failed and asks if the users wants to continue. The user
is also informed that the HPA/PARTIES area could possibly be unlocked using
the BIOS.
■
If the user wants to continue, then GDisk continues to erase the disk, ignoring
the HPA/PARTIES area.
There are optional command-line switches as follows:
