I've been trying to install a Transcend 64GB SSD and I keep getting the above error when trying to load the developer image. I've tried re--downloading the image several times, but I get the same error.

I'm able to run the disk builder without errors, so I don't believe that I've got a bad cable or port (also: I'm able to run a pair of conventional drives without problems). I've double- and triple-checked the physical connections and they seem good (and if they were bad, the disk builder would error, wouldn't it?).

I've tried searching the forums. but haven't found anything yet that helps.

Can someone give me some help with this? I'm willing to believe that I've overlooked something, but I've no idea what that could be right now.
