So here's the deal. I got a new WD Passport Essential + Smartware (the new one) as it was on sale. So I partitioned it with GUID map gave a nice Mac OS Extended Journaled partition then I made a FAT partition, went to my cousins PC and Ubuntuized the FAT partition with Unetbootin. I couldn't test it there because I went in a rush. Got home and tried to boot it. And of course while pressing alt it didn't recognize it. Did a little searching and supposedly Western Digital drives don't work well with PPC macs when it comes to booting. I can't test it with a LiveCD or a Windows machine. I would say it was because of the PPC issue but this is an intel mac. Any idea's? An answer withing the next 30 days would be nice so I could return it
