Hello, since I have to replace the processor in my lombard I thought I might as well upgrade its 8gb hard drive to. I read on low end mac that certain ata-6 and ata-7 drives are not compatible with the lombard. It's taking me forever to search through serial numbers just to find an ata-5 drive and I'm afraid to say I'm not really sure what ata means. (http://lowendmac.com/pb2/lombard-powerbook-g3.html) can anyone recommend a lombard compatible hard drive? Or this this not such a big issue? many thanks.
