The !can_write_kdump extension verifies that there is enough disk space on the target computer to write a kernel dump file of the specified type.
!can_write_kdump [-dn] [Options]
Specifies that the file system on the target computer is an NTFS file system. If this parameter is omitted, then the amount of disk free space cannot be determined, and a warning will be shown. However, the amount of space required will still be displayed.
The following options are valid:
Specifies that the extension should determine if there is enough space for a minidump.
Specifies that the extension should determine if there is enough space for a summary kernel dump. This is the default value.
Specifies that the extension should determine if there is enough space for a full kernel dump.
Windows XP and later
If no Option is specified, then the extension will determine if there is enough space for a summary kernel dump.
In the following example, the file system is not specified:
