I am looking for a way to create a complete copy of a hard disk. Not just the volumes on the disk but the partition map, all volumes and even non Mac OS volumes, like DOS or Linux.
I am hoping for something similar to the Unix dd command. Any ideas?

What sort of OS are you using ?
System 7 ? or earlier ?
OS 8 ?
OS 9 ?
OSX 10.3 or earlier ?
OSX 10.4 ?
OSX 10.5 or later ?
Linux ?
Windows ? which one ?
OSX would be the easiest. dd exists there, but I've never used it on raw disk. There are all the other unix disk and backup utilities available. As well as hdiutil, for making, converting, mounting, doing everything with hard disk images.

I am trying to use os 7. I can get 8.1 on my machine. The problem is I need to send the image to a scsi disk and my mac is the only scsi machine I have.

Not the answer we wanted to hear. In short it's not going to happen.
Perhaps some more detail will mean we can provide a workaround. All we know so far is that you want to get some sort of disk image onto your SCSI disk in your Mac. How about explaining the full story of what you're trying to achieve and why, with details of all the kit you have available.
ie. trying to install Yellow Dog Linux 2.1 on my Mac IIci with a 3.2GB SCSI disk. YDL is a 300MB ISO download currently on a Mac partition on the SCSI disk. I also have a PC with Windows 7 and SATA drives, and an external CD drive for the IIci.

I have a Centris 650 with 520mb hd. I have an external Zip drive I am trying to make a complete image of for backup.
What I have come up with is I am going to install netbsd to a Jazz drive I have and use netbsd to do the work.

Did you use the restore CD from performa?

Toast can perform 'Device Copy' which could be what you´re looking for. It makes an image from a low level 1-to-1 reading of the device rather than volume/-s. Can´t remember though if it compress the resulting image. If not you better make sure to the space ready on your HD.

Will Toast let me go to arbitrary devices?

I *think* as long as it is SCSI or internal. Mac OS doesn´t have to be able to mount any part of the device as long as it behave 'properly' as a SCSI property ie can be found in the SCSI chain with a correct ID.
At this moment I´m making a image with Toast from a SCSI disk formatted for use with BeOS which can´t be read/mounted by Mac OS so I guess there´s a fair chance you can use this method too.

Cool that would save me a lot of time. I ran Toast v4 in BasilliskII but it didn't recognise anything, but since BasilliskII only does SCSI stuff that makes sense.

Sorry I meant it doesn't do any SCSI emulation just patches the system to allow the image.

Re BasiliskII; I *think* (again) that if your host computer carries a real hardware SCSI chain, ie a SCSI card, BasiliskII can handle real SCSI disks too. I´ve got an Adaptec 2030, bootable, on my G4 but the only external SCSI HD is the one w BeOS, so it´ll be another day to try that out.

I've heard that it can't use a scsi bus unless you are on linux, or mac os. I unfortunately am trying to do this with a windows machine. Regardless I don't have another machine with a scsi bus. I lucked out that my Zip can be scsi or parallel. Which let me tell you is really slow.
Any ways, I tried Toast and it didn't recognise my Zip drive, so my Jazz drive is probably out of the question.
