I have a G4 533mhz and I have just bought a Seagate 160gb hard drive. When I turnedd the computer on it asked me to initialise the new drive, so I did. However it is only indicating that the drive has 31.34gb available! Are there any 3rd party apps to initialise this drive or is it too big for my computer to handle? (I used to have an 80gb drive and it worked).
