My Mac doesn't recognize the size of a new Hard Drive

I have a PowerMac G4 1.5mhz and just installed a 2nd hard drive. It's a 160GB HD but the computer just recognizes it as a 128Gb.
I read that I need an ATA card to make it work but I'm not sure of which card I should buy.
Does anyone knows it?

Thanks for your help!!!

Early model G4's such as Sawtooth, Gigabit Ethernets, Digital Audios etc. can recognize up to 128GB only. Go to OWC web site to look for a IDE Controller Cards.

Here is the link:-

that's what I wanted to know!

thanks!!!

If the mac compatible controller cards seem too expensive then try a cheap USB 2 card and an external encosure
