Wierd , no one posted something like : Good job or something :-? maybe no 1 needs this :-?? i dont know ...

I certainly did Roli, thanks very much. ;-)

I had swapped from IDE to AHCI thinking it would work miracles, well it didn't and things are actually faster back in IDE mode.

Thanks again.

I'd like to try your solution to my problem of a disappearing SATA drive (LG Blu-ray BH12LS38).

The motherboard is ASUS M3N78-VM. Operating system is Windows 7 Home edition.

My trouble is that when I try to reset the BIOS, there are only three choices given: SATA, AHCI, and Raid. "IDE" is not one of them. The BIOS is currently set to SATA.

Might I get the Blu-ray drive up and running by installing a SATA card in an unused PCI slot?

Many thanks!

SATA is IDE on your board. Not sure about your idea for attaching a Blu-ray drive as those would normally attach to a SATA socket elsewhere on the motherboard.
What optical drive do you have now? Do what I did and simply swap your existing optical drive for Blu-ray because it is backwards-compatible and will handle 'lesser' disks. You can also get them with Lightscribe if you use that.

I see that there are such things as SATA plug-in PCI cards for plugging in external optical drives: http://www.tigerdirect.ca/applications/category/category_slc.asp?CatId=1455
