Hey Everyone I am having a really strange issue with casper imaging in our European region. Every time my techs run the image workflow they end up with an unbootable mac with the Folder icon with the flashing ?
I took a look at the logs and discovered something strange. It looks like after performing the block copy casper imaging erases the drive.



Has anyone seen this behavior before? I am unable to replicate it here in the US.



Here is the log from the jss:

Sorry, I don't have an answer for you but wanted to chime in that I am having a similar issue when updating to 10.10.3 in Caper imaging. As the laptop reboots, I have a prohibitory sign. On the same configuration, if I replace my custom 10.10.3 installer with a 10.10.1, it works perfectly (installer created with CreateOSXInstall.pkg).
Did you try 10.10.2. or 10.10.1?

the image is a never booted autoDMG that works perfectly at other sites.

If I recall correctly, block copies from a JDS are unsuccessful like you're seeing. Switch that site to a file share distribution point and try again.

What version of Casper Imaging are you using (sorry if I missed that)? I've had mixed results with some of the more recent versions. 9.72 seems reliable (have only used in test env. so far). Another consideration might be issue with diskless (lack thereof) NetBoot?

Same issue here, albeit with OS X 10.10.4 and Casper Suite 9.73

Did anyone find an answer to this? I'm seeing the same thing in a test environment I just spun up - it seems to start and stop a block copy right away, and then erase.
