There are two types of hard disks you can use with PC Task. These
are HardDiskFiles and Hard Disk partitions. If you have room a Hard
disk partition is recommended as they are a lot faster than harddisk
files. A 50Mb partition should be adequate for most people.

To set up a harddisk partition use the following procedure:

a)Back up the hard disk as this procedure will erase any files on
affected partitions.
b) Run HDToolbox, select Partition Drives.
c) Reduce the size of the partition on the right hand of the bar.
d) Select Add Partition and this will create a new partition.
e) Click on Advanced Options, and change the drive name from DHx to
something like PCC or PCD (last letter must be a C or D).
f) Click on Change File System and select Custom File System, change
the Dos Type to 0x4d534800.
g) Also turn off the AutoMount feature as this will prevent an
inaccessable disk icon from appearing.
h) Click on OK and save the changes. Reboot.
i) Format the resized Amiga partition as normal and restore any
backed up files.
j) Run PCTask and for drive C: enter PCC or PCD (or whatever).
k) Click on Start and insert a bootable MSDOS disk.
l) You will need to run FDISK to create a Primary Dos partition and
activate it. If creating a second disk such as D, change which drive
to use (option 5).
m) Format the partition using the command: FORMAT C: /S
n) Install MS-DOS and any other software. NB: Some DOS installers
will format the drive for you so step m can be left out.
