We are having a similar issue. I have created a "host" computer to do the Target Mode Imaging. I can image two or three computers, and then any new computers are not detected by the host. I have to reboot the host before any new computers are detected again.

Any ideas?

I used Target Mode imaging last summer and very, very seldom had one of these issues. Now it seems to be prolific. I would like to see this revisited. If anyone has any solutions that would be great.

This exact issue is occurring in our environment as well. We have 4 imaging stations running Target Disk Mode and each one of them can only image up to 5 computers before it stops recognizing new or previous devices. Rebooting the entire imaging station is the only way to get it to recognized attached devices again. This has become a significant bottleneck in our rollout of 1:1 laptops for this coming school semester. Any advice would be appreciated.

buy a thunderbolt external disk, put a bootable OS on it, boot each machine from that OS, build it, then you reboot each time :)

Having this problem as well. Has been going on for quite some time and also having a 1-to-1 system to image and roll out it has caused quite a pain to reboot after every 2-5 images. Especially if you start working on something and have to reboot in the middle of your thought because the computer won't recognize the new machine.

I would like to see this fixed as well I only have a few test machines.

I have created a feature request for this.
