Well, to be more specific, the HD LED stays on and the system becomes completely unresponsive.
This is a complete pain in the a$$.
All my HD's are SATA-II and fairly new, my TSSTcorp DVD-RW had an old firmware on it which I just upgraded, but I don't know if that will help; I have done some research on the web and have learnt that this issue can be linked to a conflict with DVD drives as well as USB devices. Perhaps the JMicron Controller cannot properly co-exist with the ICH9R controller.
I tried the iaStor(v) registry fix by deleting the Parameters section, but that didn't seem to help.
Apparently the problem is supposed to go away if you disable the new functions of SATA-II, so unless the RAID boot ROM is setting LPM information automatically, or there is a device conflict, the registry fix should have actually worked.
Is it really linked to LPM? who knows.
I suppose we can always hope that the next BIOS update will contain a new revision of the ICH9R controller BIOS.
