[Coco] .DSK Partition extract/inject tool?

Tue Sep 24 23:59:17 EDT 2013

Here is my tool. It can work directly with superIDE CF images in linux or
using CygWin.

Compile it as: g++ side.cpp -o side

It is pre-set for use with a 256mb (245mb nominal) superIDE card. To use
with any other image you need to provide some options:

-dw : DW images (256-byte sectors)
-s <sector-count> : number of sectors in your disk image. Multiply the
number of .DSK x 630 + the number of sectors of any existing OS-9 partition
on it.

Complicated ?

For use with a drivewire.dsk image of 10 concatenated disks without an OS9
partition the sintax is:

extract:

side get disk5.dsk 5 dwimage.dsk  -dw -s 6300

insert:

side put disk4.dsk 4 dwimage.dsk -dw -s 6300

Well you can change it the way you want, if you only work with DW images
you can make it default and also deduce de number of sectors by the image
file size. I didn't do it because when using a CF card as image I don't get
a file size and this size varies from CF to CF.
