AHCI Driver constantly pinging disk on Windows 7

I'm using the Intel 5 Series 4 Port SATA AHCI Controller driver.  I recently updated to the latest version ( 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.
