I installed an LG Blu-ray burner as a second drive, but I can't get it to work in Windows 7 64 SP1. Mac OS recognizes it properly, but Windows 7 doesn't. I hacked my MBR and registry to boot Windows with AHCI mode, and Windows now reports that it's running in AHCI mode, but the drive doesn't show up. I tried installing the Intel SATA raid controller drivers, but that didn't seem to work, either. Any ideas? Thanks! Melissa ---------- An addendum: This is an "early 2008" Mac Pro. This means that the Hitachi "SuperDrive" it came with is standard IDE/parallel ATA.
