4coredual SATA2 R2.0 won't allow SATA drives

[exxocet]

Hi guys,
I'm running Win 7 64-bit on ASRock 4coredual SATA2 R2.0 mothereboard, 4GB DDR2, ATI HD3850 AGP video card. BIOS 2.20A, from PCtreiber.

I have 2 IDE HDD and 2 IDE DVD drives, so all IDE inputs are used. As the DVD-RW seems to burn badly lately, I've bought a SATA ASUS DRW-24B3LT DVD-RW, unfortunately there is no way to install it.

In non-RAID the drive is recognized in BIOS, but not in Windows and the OS hangs, HDD LED is always ON.
In RAID CMOS config, the SATA DVD-RW is recognized in bots BIOS and Windows 7 (although the OS boots very slow), but it won't read or write anything. The drive is OK, was tested on another desktop and it worked well.

I've tried to remove IDE DVD-RW and use only SATA DVD-RW, to clear CMOS, no chance. I've had installed V-RAID 6.10, but still no improvement.

Any idea please, maybe someone who had this issue before could help. Thank you.

On my Gigabyte board, I had to set the SATA channels to legacy IDE mode. I didn't need them on RAID mode, and that's the only way the SATA DVD burner would work. Don't know about Asrock's BIOS but you should be able to change each SATA channel seperately.
