vista beta2 ibm thinpad ultrabay cannot detected

Vista Beta2-IBM ThinPad Ultrabay cannot be detected.

I have IBM ThinkPad T40 and Vista Beta2 OS. I have a extra ultrabay with another HD and every time I try to swap hard drive with CDR-DVD they not detected by Vista. Ultra bay is hot swappable and I never experienced problems with my previous WINXP. Only after restart secondary drive or appears in Explorer. I’ve tried everything but no luck...
