Table 5-3
Create switches (continued)
Explanation Switch
Indicates that the partition is not formatted as FAT32. Limits primary
and logical partitions to 2048 MB. Partitions over 16 MB are formatted
as FAT16. This switch is useful if the operating system does not
support FAT32, such as Windows NT 4. /-32
Lets you create a FAT16 primary or logical partition, up to 4097 MB.
The cluster size is 64 KB. Partitions over 16 MB are formatted as
FAT16. DOS systems may be unable to access partitions that are
created with this switch and are over 2048 MB. /ntfat16
Reinitializing the Master Boot Record
You can use the /mbr command to rewrite the boot code in the master boot record
(MBR). For example, you can use the /mbr command to reinitialize the MBR to
eliminate a boot-sector virus. You can also use the /mbr command with the /wipe
option in DOS to delete a dynamic disk.
Note:
You must use the /mbr command when you delete Linux partitions if LILO
or Grub resides in the MBR.
The syntax for this command is as follows:
gdisk disk /mbr [/wipe] [/p] [/z]
GDisk.exe
gdisk disk /mbr [/wipe] [/p] [/z]
gdisk
gdisk32 disk /mbr {/p /z}
GDisk32.exe
gdisk64 disk /mbr {/p /z}
GDisk64.exe
Table 5-4 lists the mbr switches.
