Nevermind. Driver is fine. Blinking light was due to Windows pinging DVD for autorun functionality. Disabling drive (I rarely use it) stopped blinking. Microsoft SysInternals tools show a lot of "idle" state disk writes but that's the nature of Windows according to some feedback I got at Microsoft TechNet. I was able to reduce these (for the sake of SSD longevity) using msconfig to only start what I appear to need. I'm a happy camper.

A couple things I forgot in last post: 1) Same thing happens in safe mode and 2) Performance Monitor shows the System process doing the writing Both oif these, along with what I mentioned before, have me pretty convinced it's the driver.

I'm using the Intel 5 Series 4 Port SATA AHCI Controller driver. I recently updated to the latest version (10.0.0.1046) in hopes of solving the following issue but no such luck.

My disk activity light blinks from startup to shutdown at appx. 1 second intervals. While I have not directly verified what's causing it on my system yet, I found a thread at a Windows forum describing exactly the same issue and the poster isolated it to this driver. He solved the problem by removing the driver because he didn't need the functionality. Unfortunately, I do since I recently installed a SSD and need AHCI support for it. According to the thread poster's data, these accesses include writes. This is particularly troubling as SSDs lifetimes are typically limited by write/erase cycles.

Anyone?

Thnaks.
