Managing partitions using GDisk

The four commands to be executed are a combination of the original command 
plus the commands from the batch file:

gdisk 2 /y /del /all
gdisk 2 /y /cre /pri /-32 /for /q
gdisk 2 /y /cre /ext
gdisk 2 /y /cre /log /-32 /for /q

Batch files may be nested recursively. For example, a second file called Std_init.txt 
contains the following lines:

1 /batch:two-new.txt
2 /batch:two-new.txt 

As a result, the following command performs the actions of Two-new.txt on both 
fixed disks:

gdisk /batch:std-init.txt

FAT16 partitions can be up to 4 GB in size using 64 K clusters in Windows NT. 
GDisk can create a FAT16 partition using 64 K clusters when the 
/ntfat16 switch is added to the create partition command line. This switch 
disables the creation of FAT32 partitions and allows the creation of FAT16 
partitions up to 4 GB. 

Note: DOS and Windows 9x do not support FAT16 partitions using 64 K clusters 
and are limited to 2 GB FAT16 partitions.

GDisk lets you delete data and partitions on your disk or wipe your entire disk. 
You cannot delete a dynamic disk partition with the /del switch.

The switch /del /all deletes all partitions that are on the disk. Any other space that 
has not been used for creating a partition is not deleted. Deleting an extended 
partition also deletes any logical partition within it.

The /diskwipe switch wipes the entire disk, partitions, partition table, MBR, and 
all used and unused space.

These switches function with GDisk only.
