Unable to Create a Disk Image of Device

Hello.

The MacIntosh is a Mac Mini w/1.83Ghz Intel Core 2 Duo. The OS is Snow Leopard, 10.6.2. I am unable to create a disk image of the device "Macintosh HD".

Here's my procedure:
1) Reboot the Mac Mini from the Snow Leopard Install Disk
2) Set Language and then load "Disk Utility"
3) Select the Macintosh HD from Disk Utility
4) Set "Create a New Image from Macintosh HD"
5) Leave the settings as they are (type of disk image is "compressed" target repository is root home dir)
6) Error message is "Unable to create Macintosh HD (error -61)"
7) When I then try to create a blank disk image, once again, with root home as repository the error message is "Unable to create name.dmg (read-only) file system"

Any suggestions how to fix?

Thanks

Mike

where exactly are you trying to save the image to? I'm not sure what you mean by root home directory but if you mean / that's set to the DVD drive when you are booted from the DVD. of course that's a read only file system and you can't write anything to it. and you can't save a disk image of the main hard drive on that hard drive itself. you need a second hard drive.

you can smb from terminal but it will not help you. you'll need to create a folder which will serve as the mount point first and where will you put it? you can not do it on the dvd. and you can not put it in the main drive itself. but why do you need to do it that way at all. there is no need to boot from the DVD period. boot normally and clone your hard drive to a remote disk image on an smb share using one of many backup programs that can do this. Superduper can do it. so can CCCloner.
