MAC: Restore Failure: An error (32) occurred while copying image. (Broken Pipe)

Question

I have a disk image that I created of the Bootcamp partition on my old mac. I copied that image over to my new mac. I created a new Bootcamp partition on the new mac and am attempting to restore the image using Disk Utility. When I do that it gives me the above error. I have been unable to find any information on why I would be getting this error. Anyone have any ideas?

I found this here: http://forums.macrumors.com/archive/index.php/t-997823.html It sounds like it might be what you're experiencing.

After analyzing and trying things out, I was able to solve this. It seems that Boot Camp does not flag the partition as ACTIVE immediately after Boot Camp creates the new partition from windows.

Assuming you already have a .dmg image of your previous Windows Boot Camp partition, do the following:

1. Use Boot Camp to allocate the new space. Don't use Disk Utility because the MBR will not be configured properly

2. Use Disk Utility to restore your .dmg image to the new Boot Camp partition you just created. Be sure to run IMAGES --> SCAN IMAGE FOR RESTORE in Disk Utility before restoring. You may need to unmount the Boot Camp partition in Disk Utility before it begins to restore.

3. Use fdisk in Terminal to mark the Boot Camp partition active. First, enter the fdisk MBR edit mode by running the following:

   $sudo fdisk -e /dev/disk0
   

   Ignore the error "could not open MBR file /usr/standalone/i386/boot0: No such file or directory". Then, determine which partition number to mark active by running the following (in bold):

   fdisk: 1> show
   

   Your windows partition should be #3 labeled "Win95 FAT-32". Now, mark the partition active:

   fdisk: 1> flag 3
   Partition 3 marked active.
   fdisk:*1> write
   Device could not be accessed exclusively.
   A reboot will be needed for changes to take effect. OK? [n] y
   Writing MBR at offset 0.
   fdisk: 1> exit
   

Now, reboot and hold the OPTION key and Windows should be listed as a bootable option.

Go into your energy saver settings and select Computer Sleep (NEVER) and Uncheck the box that allows it to sleep hard disks. This is why you get a broken pipe because the CPU and disk shutdown mid-restore when you leave it idle.
