[linux-lvm] pvcreate problem on new IDE disk

I just installed a new 120G IDE disk. My system currently has two 32G SCSI
disks. I intend to migrate the data off of the SCSI disks on to the IDE

My version info:

Linux home 2.4.19 #7 SMP Sat Apr 19 18:04:41 PDT 2003 i686 unknown unknown

home:~# pvcreate --version
  LVM version:     1.95.10 (2002-05-31)
  Library version: 0.96.04-ioctl-cvs (2002-08-14)
  Driver version:  1.0.8

The drive is a 120G Maxtor IDE drive. I have a 1G partition (which I will
eventually reinstall the OS onto) and a ~120G partition which I want to
initialize as a physical volume, add it to a new volume group, create some
LV's, and then copy the data from my existing disks into it. 

   Device Boot    Start       End    Blocks   Id  System
/dev/hdd1             1      4064   2048224+  83  Linux
/dev/hdd2          4065    238216 118012608   8e  Linux LVM

But when I do the pvcreate I get this error:

home:~# pvcreate /dev/hdd2
  Failed to read existing physical volume '/dev/hdd2'
  /dev/hdd2: Couldn't find device.
  Failed to setup physical volume "/dev/hdd2"

Googling on "Failed to read existing physical volume"  produces zero hits.
Nothing at all. Any ideas?
