I have something to add to this. Have been using .32 without issues. Recently received a batch of HP z230 workstations. Updated to the newest fog kernel and had no issue uploading a custom image with the 32bit win 7 installed on it. But when I attempt to upload a custom image (that I created from the install dvd) with 64bit Win 7 installed, I get the error. So it seemed like something with 64bit win. Wiping the partitions, and clearing mbr doesn’t seem to help.

Three observations here…

1. The original “untouched” 64bit hp load can be imaged with no issues, although it looks like it may take 8 hours to do so
2. If I pull the original hp hard drive that came with the machine, and replace it with a 1TB Western Digital (Blue) drive…off of my shelf…things work perfectly. No problem uploading a win7, 64 bit imge.
3. I checked the original hp load, and it is using the gpt partition. Sectors are also 512 bytes.

Like others, I am in a production environment, and was hoping to hold off on updating fog server until after summer 2014.

Anyone else experience this? Any ideas?
