SATA RAID0 and Plextor SATA DVD0-RW DRIVE system hang

Fri Feb 10 16:07:52 PST 2006

HI I am having great difficulty with my SATA DVD-RW drive.  It is a Plextor  PX-716A ver 1.08 and is serial ATA seems to work/detect as acd1 fine before.  However I cannot remember if i could mount it but did not try very hard and do not exactly know what i am doing with dvd-rw and FreeBSD yet.

I compiled atapicam into the Kernel as per the handbook 17.5 the below related options were already there as i am running a Generic Kernel other than atapicam

device scbus
device da
device pass
device uhci
device ohci
device usb
device umass

When i try to boot with the drive plugged in the system hangs while detecting the drives. Must be reset with the drive unplugged to get fbsd back.  Note i tried playing with the bios settings changing from enhanced sata to legacy and some combos of that.  Also tried the  the plug and play os off and then on nothing seemed to make the system boot with drive attached.  

I use a INTEL  D925CV2 with built in raid see below about drive configuration ( this is without Plextor drive pluged in ) and a unmame output.
