160gb disk showing up as 137gb

[Wakko Warner <wakko@animx.eu.org>]

Just bought a maxtor 160gb disk and it shows upt as a 137gb disk.  I thought
this might be the system board's ide chipset limitation so I put a scsi->ide
adapter on the drive.  Same situation occurs.  I'm looking at what the kernel
reports when it finds the drive.  /proc/partitions shows this drive as:
   8     0  134217727 sda
/proc/scsi/scsi shows:
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: Maxtor 4 Model: G160J8           Rev: GAK8
  Type:   Direct-Access                    ANSI SCSI revision: 02
     
I tried kernel 2.4.14 and 2.4.18.  Any ideas?
