disk Commands
disk zero
To clear an entire SCSI disk, use the
disk zero
command. When
you clear a disk, all data is erased and cannot be recovered.
Command And Switch Availability
This command and its associated switch (or switches) are supported
on the following operating systems:
■ Windows NT
■ Windows 2000 (basic disk only)
■ Windows XP (basic disk only)
■ NetWare
Syntax
disk zero [/always{=boolean}] [/wait{=boolean}]
{scsi_device}
Parameters
{scsi_device}
Specifies the ID for the SCSI disk you want to clear. A SCSI ID
consists of a SCSI channel number (for example, 0, 1, 2, 3, etc.),
device ID (0 through 15 inclusive), and device logical unit
number (0 through 7 inclusive). See the
scsi_device
section
on page 3-7 for more information on how to specify the SCSI
device.
Switches
/always{=boolean}
Specifies whether to clear the disk, even if it has data on it. If
you specify
TRUE
, the command clears the disk even if it has
data on it.
The default behavior for the command is
FALSE
;
the command
clears the disk only if it has no data on it. Specifying /
always
overrides this behavior.
In both cases, all user files must be closed. The
/always
switch cannot override this restriction.
