Windows 7: Disk Management (Snap in) shows swaped Disk0=D and Disk1=C

Steve, that experiment was wild! So the drive reverts back to the original date on restart? Yikes.

And Ms Fitzgerald.... presenting facts that do do fit with the theory is just disruptive!
What is fascinating in your case is that the 'install' date is yesterday? What could possibly explain that? Has your computer been on since yesterday? Even so, why is Steve's retaining the original date and yours is the most recent? A clue perhaps?

Not that it means anything we can do but how about my drive #3.

Well, excuuuuse me!

Those are first install dates. And the computer has been turned off and on numerous times.

Right now, I'm more concerned with getting the stupid machine to update Windows. It's being a total butthead.

You saw how I did my install. I always do my installs that way, cause I know it to be correct (i.e. no variables).

SATA 1 = SSD
SATA 5 = Optical (for installation disk - and I install all my major programs before I connect any HDD's.)
Nothing else attached.

And this time my SATA 1 SSD comes up as Disk #3 (0 --> 1 --> 2 --> 3). But in the BIOS (either in the BIOS or on the flash screen, I see the SSD is correctly on SATA 1)

OK, now someone might submit, "well, then it's just random". Well, that's not possible. Because even a random number generator does not really generate random numbers. Actually the closest you can come to "random" is the noise off a star.

So what am I saying? That there really is a pattern/algorithm or something by which MS appears to randomize or scramble the BIOS SATA drive order.
-or-
It has something to do with SATA drive architecture. Why do I say this? Well, two very valid reasons:

1) I really want you guys to think I'm smart.

2) I think this scrambling of drive order also happens in Linux - with SATA drives.

Well, just to confuse the issue a little, the install dates for all my drives were on another motherboard. I had to RMA the board twice, so they were actually installed 3 times on this machine on 3 motherboards (same make, model). But, they show the install date and first install date as the date I installed Windows when I first built this rig. To further confuse the issue, two of the drives came from another machine which is still running and was built about 3 months before the installed date. This motherboard was placed in this machine the last time on March 2nd or 3rd. All 3 drives list the install date as 10/19, which is about the time I built this rig the first time. Due to the fact that the RMA'd boards were the exact make and model, I never reinstalled the OS. This is the same OS I installed when I first built this machine. It seems to me that the install date coincides with the installation of the OS and not when the drives were first put online, or put in the machine.

Now, are we doing this because we are really OCD or because we are control freaks or is there a difference.

This topic has been discussed many times and point out that I still think one of the Mods - Dwarf has the best reason why it may happen at least:
Diskpart / Disk Management vs the BIOS
As commented as long as you know what drive is physically connected to what it doesn't really matter. But for some irrational reason it's annoying.

Of course it matters; we just must adapt (mutter, mutter, mumble, mumble).

I'm hearing that it makes no difference what SATA port (1-6) you attach your SSD or HDD for OS/Programs. I'm sorry, but I don't believe that for a minute.

OS/Programs SSD/HDD - SATA 1
Setup optical - SATA 5
No other drives.

Rest assured that it is correct. Either chisel it in stone or tattoo it on your most prominent body part. RAID setups are even more SATA port specific/sensitive.

All you care about is your SATA 1-4 is for SSD/HDD (with SATA 1 for Boot) in a JBOD array, 5, 6 for opticals. Most people will tell you SATA 1-4 should be set to AHCI, and SATA 5,6 to IDE. That is nonsense. Set them all to AHCI. I have 11 drives (9 SSD/HDD and 2 optical drives) in each of my computers, so I can't just hook 'em up willy nilly.

You can give a royal hoot what the disk order looks like in Disk Management. Why?

Disk drive numbers may not correspond as expected to the SATA channel numbers when you install Windows on a computer that has multiple SATA or RAID disks

I still maintain that it has more to do with the disks being SATA than it does with MS being obtuse. As I mentioned, I'm pretty sure the Linux folks have anguished over the same problem. I'm new to Linux so I can't speak with authority on that.

Reduction to Absurdity: I attach my OS/Programs SSD/HDD to SATA 5 and my opticals to SATA 1-4.

Please don't tell me that's what you folks mean by "the SATA port does not matter".
