I don't think so. 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. B
