Switch | Explanation |
|
|
/for | Formats the new partition once it has been created. Unless the |
| /ntfat16 |
| 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. |
|
|
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.
