I am using Mac OS X 10.4.8 on a Mac Pro with the original hard drive.
I am unable to create a disk image using Disk Utility. I get the
error:
"Unable to create "disk0s2.dmg".
Resource busy.
This happens whether I select the top level Hard Drive icon or the
"MacIntosh HD" one representing the partition. And it happens whether
I try to save to a file on the same disk or on an external drive.
When I make an image of just a folder, it works.
Pressing Ctrl-Option-Esc shows only the Finder and Disk Utility
applications running.
The result is the same if I boot into safe mode.
Thanks for any suggestions.

I have run into the same sort of thing, but not trying to do what you
are. In almost every case I cannot find any process that should be
running.
My solution is to shut down. That should end any processes that are
running. Then on re-boot make it your first order of business to do
what you are trying to do. Before any other processes can get going.

There are two ways to spell Ockham/Occam. Britannica prefers the former.
Yon cannot make a disk image of the partition from which your booting
from, the correct way is to have two partitions each with a bootable OS
you boot from one make disk image of the other...
If your hard drive is one partition the you can do the same from the
installer DVD/CD by booting up using the C key, navigate to Disk
Utility and then make a disk image from there...
I learned many years ago to have at least 2 partitions on my drive,
currently all our computers have 3 partitions....
Be aware that you will need an equal ammount of space available plus at
least 20%...
Hope this helps

not with Apple's Disk Utility.

I think the number of partitions is beside the point since even if I
had twenty partitions I would still want to backup the boot partition.
And having more than one be bootable (with the same OS) seems like an
unnecessary hassle.
If I have to buy a separate imaging program, then so be it. But it
would make a lot of sense if the disk utility's interface SOMEWHERE
said that doing this with the booted partition will not work (if that
is indeed the case). This would have saved me a lot of wondering what
was wrong.

It is besides the point if you insist on imaging what it seems
not wholly reasonable to image, namely a partition specifically
created to be useful in imaging other partitions. It is not quite
as bad as trying to photograph the only barber in the world who
shaves all and only those who do not shave themselves but it
reminds me of it.

The guy is plonker and not worth the effect, he asked why he told why
and he said its an hassle...
You might tell that to the folks at Acronis (among others). They make
a fine imaging
program that is very capable of imaging any partition, even the running
one.
I tried the method of booting from the CD, and now I get unable to
create *.dmg, "file too large". There is about 230GB free on the
destination, and the source has about 50 GB of data on it. I tried it
going to FAT32 and Unix type partitions. I wonder if this is because
the source 'capacity' is more than 230GB?
Apparently the disk imaging feature is worth less than the extra amount
it costs.
