You are right.
dmesg shows that the "drive" is found and accessable to the system.
HOWEVER, no partitions. Or more properly, no partition table! ????
Confirmed by fdisk.
I then did a dd of the first 512K of that disk, and then ran strings on
it. When I did that, I saw strings like "GRUB," "Hard Disk" and such
fairly early in the file.
I also saw "LVM2," which I know is the beginning of LVM2 meta-data. I
can see a nice block of at least two different revisions of LVM2
meta-data on this drive. ( I stopped looking there. )
I tried a tool know I know of called "testdisk," which attempts to
recover partition tables, and it wasn't able to help. Odd.
Still looking.
