Blinking Hdd Status led, Intel Matrix Storage Controller

[Varsis]

As posted. I have a blinking hdd sstatus.
its blinking about once a second and its irritating me. I want it dead.
Does it during bios and boot up when hdd isn't being accessed. and in idle on windows. FRESH win7 install.
its on an ICH9R intel matrix controller, a cdrom in slot 5, and 2 150gb 2nd gen raptors in 0 and 1.
Any ideas?

For 6 months the same thing has been slowly driving me crazy! I have the ASUS Maximum II Formula with the ICH10R chipset running Windows XP sp3. Using a RAID0 configuration for the OS and a spare drive for backup all running through the intel chipset. So I tried swapping out different hard drives tinkering with BIOS settings, unplugging multi-card readers and so on... What finally caught my attention was moving all hard drives off the ICH10R chipset and unplugging my SATA BD/DVDs from the intel chipset. It stopped! That told me it had something to do with the intel chipset and the cdroms. So after some digging around I found this:

Stop AutoPlay on all BD / DVD / CD drives by:
- Run -> regedit
- Navigate to /HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Cdrom
- Edit/Create(REG_DWORD-Hex) "AutoRun" and set to "0"

Disabling AutoPlay stopped the system from "polling" the cdroms every second when my system was idle and perfmon (Performance Meter) showed no disk activity at all. For some reason the ICH9R and ICH10R intel chipsets are picking this up as strong disk activity. I also noticed my AVG antivirus was "ticking" my hard drives to death with it's resident shield adding to the confusion while I was troubleshooting. That was a long battle, but it appears I finally won. I hope this helps someone else out. It my searching I ran into this link which helped with some good suggestions
