I looked but I couldn't find a way for GRUB to say how many sectors it sees.  What is the command?

I tried --disk-module=ata and now I get "error: device not connected." and then the menu appears. 
My LVM partitions are recognized and I'm able to boot Linux.

So it looks like this workaround solves the problem.  I think you can close this bug.

Thanks for your patience and your help!
