Os X Snow Leopard Disk Image

So i made a back up image of my system and put it on an external HD so i could upgrade my HD. Now when i try and open it says it can't mount it? So i can't open that DMG but i can open others. Blows my mind! I was reading about the ASR command but i am not sure how to use it. Any ideas?

What did you use to create the image? My guess is it is corrupt. Suggest you use CarbonCopyCloner (which is free):  http://www.bombich.com

Make your you tick the box to "make bootable".

You could also try running Repair Disk from Disk Utility on the image, or see if  Disk Utility will force it to mount.

When i try to Repiar disk it won't do anything. ON the Disk write status it says not mounted read only. Also i tried the bombich and downloaded the carbon copy and that app can't open the DMG. i should just smash my head off my keyboard now i think. lol

Are you saying you erased the original drive before checking to make sure the disk image was good?

If not, just erase the image and re-image it with CCC.

I'm saying i plugged the original drive in to a HD jumper that lets you plug an external drive in to another comptuer via USB and the solid state started to SMOKE!

What software did you use to create the disk image? What format is the external drive in (i.e. Mac format, FAT32, NTFS)?

You are losing me here. I need a lot more information.

What model Mac are you using? Is the original drive still in the Mac, or did you put it into an external case? Did you clone or image the drive and if so to what. I am not getting the picture here of what you have done so far. Could you please explain in great detail?

I went out and got a new 1TB hd for my macbook pro. Before installed the HD i used disk utility to make an image of my machine. I am on snow leopard on a mac book pro.  Everything went smooth untill i tried to load the new image.

So when it did not work i was like oh i'll just jump the other drive and plug it in via usb and to a transfer like that. Thats when the old HD started on fire. So i only have this DMG file.

If not, you might be able to recover some of the data using DataRescue III. There is a free demo here:

Try highlighting the disk image and typing Command-i (For GetInfo) and make sure you have read and write permissions for the image file.

Sorry, I think our posts are out of sync. I am not sure which of my prior three posts you were responding to. Did you try all three?
