Could someone confirm that the following IDE Controller will do what I need it to do?

It's for a G4 PowerMac (that's about all I know about it). The individual purchased a 250 Gb IDE driver for it. But it turns out this PowerMac only supports something like 128 Gb drives. So I understand that by buying this IDE Controller, he will be able to make full use of the HD.

Thanks for the input.

ya, it will do what you want.
