I have owned my LG Super Multi Combo Drive (model GGC-H20L) for 6 weeks now and it suddenly stopped working... 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?

In reality, is there any point to more than 1.5x transfer speed on BD-ROM at present? The only media out there at the moment in BD-ROM format is BD movies and they only require a 1.5x speed player/ROM. Testing the read speed on BD movies at faster than 1.5x is really a synthetic test only since the movies will only be read at 1.5x. 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.

Now you have the same model number that can write BD also. Is this only a matter of flashing software?
