I can't get the drive to show up at all -- it causes the P.O.S.T. to take about 120 seconds or better to scan the IDE/SATA channels and never finds it... Windows XP can't see it either any more...
Can anyone help me?
It may be years before games or apps ever come out on BD-ROM and it's not really economically viable for most of us to get a BD Burner yet. BD-R media can be read at the higher speeds.
