As soon as I have both drives back into a RAID1 array, (http://forums.seagate.com/stx/board/message?board
My ultimate goal is to be able to provide Seagate with PROOF that something is defective with the 7200.11 drives which render them inoperable due to a RAID configuration. This is assuming of course that this is the case, which based on reports from this thread, seems extremely probable.
Can someone please recommend some sort of "controlled" tests that migh thelp us narrow down the issue?

After several google searches for the many problems with my computer, first with the terms 'security options failed to create logon process' and countless others, I finally found this his with 'iastor1 time out' message. This thread describes exactly what has happened to me over the past year.
I have two Seagate Barracuda 7200.11's, and ever since about 8 months ago, VERY infrequently, my computer would crash (usually overnight, possibly due to a large amount of access) and then upon reboot the drive would be any combination of degraded, not found, not readable or simply not even there. But as some have stated, this drive reappears without a hitch after a power cycle. This behaviour was an annoyance, but was not frequent enough to warrant any complaint. However, just recently, these problems became more and more frequent, and more severe.
My computer now hangs after about an hour of use, while my mouse is still operable, everything else is compeltely non responsive. This is very inconvenient to attempt to use a computer like this. Having read most of this thread is seems alot like the same issue everyone has been having, and am I understanding correctly that there is no fix for it?
Here are my specs:
2x7200.11 500GB's in RAID0 on an Intel Matrix Raid Controller; I'm not sure if it is 8/9 or 10R, but the driver version is 220.127.116.11. Running Vista 64 Bit.
My 1st hard drive in the array has been reported as degraded now for quite some time;I heard of some users 'rebuilding' their array, I am unsure if I should do that however, as I am not sure what effect that will have on my data.
Should I rebuild my drive and see if that stops the issues somehow? Or maybe upgrading to 8.8 would be benificial? I would love to know what steps I could take to prvent this from happening to my drives, but I also need to keep my data on the hard drives! Maybe I should be looking at some Samsung F3s...
Any help is greatly appreciated!

Based on the problems I've had (and others in this thread) rebuilding your drive will likely not improve matters...
It seemed that some people were having better luck upgrading (and in some cases downgrading) Intel Matrix firmware...
But you should call Seagate and open a ticket -- your use scenario (what they call Desktop RAID) is actually a usage scenario that they admit is a suitable use for the 7200.11 drives. For some reason, if you're running RAID 5 or more than 2 drives, suddenly Seagate thinks that is not a suitable use for these drives. But in your case, you are using the drives exactly in the manner that they say is suitable.
Word of warning -- if they want to RMA your drive, they'll probably send you a replacement that has the same problems.
It does seem that some folks have had better luck with drives running SD1A/SD1B firmware. Not sure what you have on your drives, but CC1H and CC1J were useless when I put them on an LSI JBOD controller.
Good luck, but we've been waiting for a reasonable response from Seagate for nearly a year...

Just to let you know, after spending a lot of time, and money, and still not beeing able to use the 8x1.5Tb drives, I went to the shop and bought the new 2Tb Hitachi drives... and they are working like a charme with even a throughoutput increase.
Conclusion is that Seagate s**x, is aware of a problem and just don't care and I will NEVER buy a seagate (nor my company will) EVER AGAIN.

Just another voice here -
I've got 5 1.5 TB 7200.11 drives part number ST31500341AS in a a desktop raid 6 array using a brand new 3ware 9690SA controller. Running under Windows 7 64 bit as a large (4TB) volume which I am using to store video files.
I'm seeing similar problems to others here - the drives randomly drop-out from the array. The controller reports errors like "drive removed" or "command timed out." A reboot of the machine fixes the problem - as long as no writes were going on at the time the array comes back in normal status. I can reproduce the problem by running a "verify" operation on the array from the controller - about 15 minutes after the verify starts, one or more of the drives will reliably drop out.
3Ware support had me try turning off NCQ, which had no impact. They also wanted to make sure there were no power supply issues - there are not, I've got watts to spare.
This problems seems very reproducable to me - don't understand why Seagate doesn't appear to be on top of it. I've got close to $1000 of their drives that are pretty much useless.
