  I played on and found:

  * OS sees all three disks
  * I can pvcreate all disks
  * pvscan does not find hdc

  In command language, starting from scratch

fafner:~# pvscan
  No matching physical volumes found
fafner:~# pvdisplay
fafner:~# fdisk -l /dev/hdb

Disk /dev/hdb: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/hdb doesn't contain a valid partition table
fafner:~# fdisk -l /dev/hdc

Disk /dev/hdc: 80.0 GB, 80026361856 bytes
