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 is supported on Windows.
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.), SCSI device ID (0 through 15 inclusive), and SCSI device
logical unit number (0 through 7 inclusive).
For further details, see scsi_device on page 1-10.
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.
