I also have the "two ODD" problem.
IRST Driver: 11.7.0.1013
HDD Drives:
SATA Port 0: WD Caviar Black SATA 2 WD1001FALS-0
SATA Port 2: WD Caviar Green SATA 2 WD6400AAKS-0
ODD Drives:
SATA Port 3: OPTIARC DVD ROM AD7240S
SATA Port 4: OPTIARC DVD Writer AD7261S
IASTORUI Crashes with error "Assertion failed"
Seems that the problem is mainly due, if there are two ODDs of the same manufacturer (here Sony), the driver is not able to distinguish the dirfferent drives.
If have the same configuration on my work PC with two ODDs, but here is one LG and one Samsung. There IRST works fine.
Best regards,
Michael
