Reinitializing the Master Boot Record

Create switches

 

 

Switch

Explanation

 

 

/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.

 

 

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.
