What's with the constant spinups? Win7 killed my scsi!

So I installed RC1 right, pritty and all, disabled indexing and set all power options to "never", naturally, played some COD4, all good, did a WEI screenshot, then the computer was idle for a couple hours, while I was browsing this forum using another pc... But I could hear my 10 harddisks spin up all the time, so I doublechecked the power options, then started looking on internet for answers, then I turn back to win7 only to find that "my computer" is not responding... I restart it and see
"ARRAY STATUS = FAILED"
It reports 2 hdds missing. Have yet to check if they're completely dead...
Nice job, windows! It managed to spin the raid to failure! I had xp running on that box smooth for almost a year already...

So anyone knows what's the deal with powering down disks?
Any disk will die if powered down every few minutes..
Especially scsi..

This is amazing!
I spent all night reading forums...
Vista had this issue, evidently, since 2007..
Here's a excerpt from Intel's website:
Cause
A change was made by Microsoft* in the Windows Vista setup process. The result of this change is that the Intel® Matrix Storage Manager LPM registry settings that were intended for mobile installations are added for desktop installations as well. These LPM registry settings are added for both the Intel® Matrix Storage Manager RAID driver on the Windows Vista installation disk, as well as for any drivers added during the installation process.
Various desktop Serial ATA devices such as hard drives and CD/DVD drives have been reported that do not comply with the Serial ATA LPM device specification and display erratic behavior when LPM is enabled.
Because the setup change means that LPM is enabled by default for all Windows Vista platforms, using a device that does not completely follow the specification may result in one of the listed issues.
A list of these devices is not available at this time.
Can you believe this! Micro freaking soft didn't do jack about this, and it's been years, they are painting flowers on the interface, yet real problems that are destroying people's hardware remain unaddressed..

I guess I replace the dead drives, fortunately I have some spares, and try to see if there's a workaround for this...
