Installed a new seagate 160GB internal hard drive

I installed a new 160 GB internal hard drive. Reinstalled operating system, but the hard drive says it's only 31.37 GB. I've tried to erase the disk and restart from the installation DVD, etc. but it won't read it as 160 GB hard drive.
any suggestions?

Power MAC G4 Silver Tower, Mac OS X (10.4.8)

Hi, jumpintoliquid -

Welcome to Apple's Discussions.

ATA hard drives use jumpers to set their address as Master or Slave.

Some drives also come with an additional jumper, which is used as a limiter to set an artifical size for the drive to approx 32GB. This is done because some (older, I think) PC CPUs could not address a volume larger than that.

The solution would be to remove that extra jumper (or reset it according to the jumper config label on the drive). This drawing from Seagate's site may also apply to your drive -

Edit - also, be sure the address jumpers are set to Master if it is the only drive on the bus.

Hey.. yes, I did that but it still didn't change it.
I read some things that said it was suppose to be changed in the disk utilities but I didn't see that option.

You might also need to erase the new drive with Disk Utility to get the space back.
