IMD format is NOT applicable for boot disks of a Commodore 128 (that's
imho the only Commodore - you didn't specify which one - which uses CP/M
3.0). You have to own a real 1571 drive (or use an emulator like VICE)
to transfer the image (e.g. use StarCommander and a XE1541 cable) with a
Just look at

hi when will cpm versions being to add code for specific hardware
we have 1-4mb of external ram on the sam coupe and if the os was paged
in ram above 32768 it would run at 6mhz - this makes a big difference
also when putting text onscreen
why doesn't cpm word processors use push
sp can point to video ram and then on older machines liek the spectrum
each register pair pushed would get 16 pixels
or on sam coupe 4 or 8 pixels for hi rez mode 3 512x192
we cant even use interlaced video modes that were pretty easy if there

I have a couple of disks that have the following geometry:
2 sides, 48 TPI, 512 bytes per sector, 10 sectors per track, sectors
numbered 1-10 on side 1, 11-20 on side 2, and side 2 headers declare
they're actually on side 1 (so essentially masking 2-sided-ness).
The following diskdef for cpmtools works correctly for viewing and
extracting files; the skew was pretty tough to arrive at via inspection:
I saw a Digital Research signature in an early sector ("COPYRIGHT (C)
1979, DIGITAL RESEARCH"), but no other identifying info was in evidence.
Any idea what type of machine this could have come from?

My Carbon application has a Mach-O Framework embedded in its bundle. I
created the framework to get at one Mach-O only function and it works
But, the problem comes when distributing this app. Originally, I just
created a stuffit archive and distributed this way. This works fine for
OS 9 (which doesn't need to call the Mach-O Framework). But under OS X,
it fails because the symbolic links to the various components of my
framework aren't set up properly when unstuffing the data.
So, I created a disk image using Disk Copy under OS X, and everything is
fine again -- it must fix the symbolilc links when the file is copied
from the disk image.
The problem is that I can't make one file that works for everyone (i.e.,
I'm left with a stuffit file for OS 9 users, a disk image for OS X).
I tried creating the disk image under OS 9, but the OS 9 version of Disk
Copy doesn't seem to like the symbolic links inside the framework
either. (It discards them...)
Is there a way to solve this? I'd really like to have one file that
everyone can use to install this software.
Many thanks in advance,

I have seen the question "What are disk images" answered numerous times
with the assurance that they are exact sector-by-sector copies of real
physical disks. But my own eyes seem to contradict that apparently
Disregarding the instant .dmg "images" which can be cobbled together in
folders on the desktop, and concentrating on sincere attempts to create
real images of real physical disks with Disk Utility, if .dmg's are real
sector-by-sector copies, how come they shrink in size when files are

After years of searching I finally found a program and was able to
sucessfully copy it from the original 5 1/4 disk to an image. It is a copy

in an emulator it asks for the original disk. Is there a way around this?
After some research I found out the original has some sort of disk key.

I installed OS 10.5.6 on a clean partition, and it is working well.
Previously I was using OS 10.2.8 which has two programs, Disk Copy, which
lets you make encrypted or not encrypted disk images, and Disk Utility,
which is for other things like verifying and repairing disks.
How can I make encrypted disk images using OS 10.5.6? The Disk Utility of
10.5.6 seems to be about the same as the Disk Utility of 10.2.8, neither
of which can create disk images.

Use a HD floppy (normally 1.44MB). You'll need the XDFCOPY utility.

...Installing Mac OS 9 on linux (MOL) with disk image file
Do you know about a howto concerning the installation
of OS 9 in conjunction with MOL / Linux in an existing
Linux / OS X environment?
I have Debian Woody with MOL, so I can boot the preinstalled
OS X under Linux. However, I would like to be able to boot OS9,
while I don't really want to repartition (and corrupt my existing
OS X and Linux installations). So it would be nice to install
OS 9 into a loopback device (hdd-image file).
Is it possible and is there anybody out there who has done this?
...cpmtools used with a floppy disk image of CP/M-86 does not work ?!
I am not able to use cpmtools with a floppy disk image file, which can
be used for VMWare or even VirtualBox.
I was using this command for showing all directory entries:
cpmls -f cpm86-144feat imagefile
But it does not show any useful info (instead just junk).
Is the existing diskdefs entry cpm86-144feat incorrect ?
# CP/M 86 on 1.44MB floppies
Or does the existing (and working) disk image files have a wrong
sector/track order ?
I am totally unsure, because I even wrote a small utility to split the
sector order to a different result:
I expected this sector order (C=Cylinder, H=Head) in VMWare/Virtualbox
C0H0 C0H1 C1H0 C1H1 C2H0 C2H1 ... up to C79H0, C79H1
The new result was
C0H0 C1H0 C2H0 C3H0 C4H0 C5H0 ... up to C78H1, C79H1
But this doesn't help to get a correct cpmls result.
Am I wrong and a skew is existing for CP/M-86 floppy disks ???

I got this disk that i/o errors on one file when I read it. Got it to
Advanced Demuffin to a normal DOS 3.3 without error, i/o errors same
place. Pulled it up with ADTpro, it doesn't i/o error there but it breaks
when it would ordinarily do a disk status check (I think). Then I replace

...making and burning disk images with disk utility
I'm having difficulty duplicating dual Mac/Win data CDs and I'm hoping
someone here can point me in the right direction. I have googled for this
and found MANY descriptions of doing exactly what I'm doing, and yet it's
not working for me. I have a CD-ROM that was originally created with Toast.
It's been years since that was done and I can't find the original Toast
files. I have all the pieces, but rather than reconstruct it, I wanted to
just make an image of the disk to store on a hard drive so I can burn new
copies whenever I want without having to use Toast again to duplicate it
from another CD. I can't figure out a way to do that with Toast. When I
make a new image from Disk Utility, the disk ends up not being complete
Here's what I've tried (procedures that are outlined on several sites):
1. In Disk Utility, I select the volume on the CD and click New Image. It
creates a dmg file. I then pop out that disk and put in a blank and click
burn. It creates something that works on the Mac, but under Windows, it
sees the disk (it's burnt and has a file system) but nothing is actually on
2. I've also tried using dd at the command line to create an image. The same
thing happens when I burn it. Fine on a Mac, not on a PC.
The original disk does work correctly. If I use Toast to duplicate it, I
also get a working disk. I'd really like to make a valid disk image that I

It's a windows system disk (fat32) and it worked fine. Windows is

Unfortunately after this dd command the new hard disk now has the
exact same size of the old one. (Though when partitioning it with
fdisk it was larger)
Is there a (simple) trick to reclaim this lost disk space?

I've just created an Eamon game on the Catakig //e emulator for the
Macintosh, and now it turns out that Catakig uses a proprietary format
to read and save files that isn't readable on other emulators. Here's
what Catakig's creator has to say about it:
"Catakig can read DSK, PO, and NIB disks, but it has its own native
format which it prefers, and which it uses for both reading and
writing floppy disk images. This format is a gzip-compressed NIB
format, which provides the versatility of that format but yields a
smaller file size, smaller even than DSK."
