Managing partitions using GDisk
Reinitializing the Master Boot Record

Use the /mbr switch to rewrite the boot code in the Master Boot Record (MBR). 
You may need to reinitialize the MBR to eliminate a boot sector virus residing 
there. You can also use the /mbr switch with the /wipe option to delete a dynamic 
disk.

This switch functions with GDisk only.

Note: The switch must be used when you delete Linux partitions if LILO resides 
in the MBR.

/for

Formats the new partition once it has been created. Unless the 
/ntfat16 or /-32 switches are used, the partition type is determined 
by the following:

■

If the partition is less than 16MB: FAT12

■

If the partition is between 16MB and 512MB: FAT16

■

If the partition is greater than 512MB: FAT32

/q

Performs a quick format if used in combination with the /for 
switch. If you do not use this switch, then GDisk performs a surface 
scan of the partition and marks any bad sectors.

/v[:label]

Gives the new formatted partition the specified label when used in 
combination with the /for switch.

/-32

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.

/ntfat16

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. Windows 9x and DOS systems may be unable to access 
partitions that are created with this switch and are over 2048 MB.
