I suspect that this is a much wider problem! I have also had the same
problems with Vista Ultimate. I have an MSI P965 Platinum motherboard with
the JMicron controller in a brand-new hiline system. The boot SATA HDD and
two PATA Pioneer DVD-RW drives were connected to the JMicron controller and
the other (raid 5) drives to the Intel ICHR8 controller. I had to fish
around to download the JMicron driver from MSI to get the system going but
everything seemed OK till I tried to burn a DVD in VideoStudio - no DVD
drives showed up! They were listed as the ubiquitous "SCSI Cd-rom" drives.
I could burn DVDs to them with Nero fine but not any Ulead products. So I
tried MS DVDMaker and same problem! I searched for updated JMicron drivers,
installed them and succeeded in crashing the system (twice) because it
removed the driver from booting. There are lots of threads all over the
internet on these issues - the common thread seems to be the JMicron
controller no matter what the motherboard. In desperation I bought new
Pioneer SATA DVD drives and shifted ALL HDDs and DVDs to the Intel ICHR8
controller, disabled the JMicron controller and suddenly everything came
good. The DVD-RWs are now recognised as such by Device Manager and all
programs. It would seem to me that the JMicron controller or its drivers
have some bugs that have not yet been addressed. Hope this helps others with
a similar problem and relieves some of the frustration.

Hi Ben. I'm glad you fixed it, but I'm curious where the 'wrong'
drivers came from in the first place. Were they leftovers from a
prior XP, maybe?
