Don't Know Why

[treadhead194]

I don't know if anyone is reading this but I'll post it anyway.
When I first installed Win 7 Home premium 64bit, the only thing I made sure of , in the BIOS, was that my first boot drive was my CD/DVD then C. I did some reading in regards to AHCI and how it could help in performance. So, being nosy I decided to try it. I found how to change from IDE to ACHI after installing Win 7 and followed the instructions. After changing over I did some looking. I found that 1. Using DISKPART, my C drive, Disk 0, was now Disk 2 and my Disk 0 drive was now D drive. I also checked in Computer Management and sure enough Windows was reporting the same thing. I didn't change the Registry entries because after bfk had tried that and it didn't work so I didn't bother.
2. I decided to revert back to IDE and reversed the process just to see what would happen. After doing so I found that my C drive was now Disk 2 and D drive was Disk 0. I switched my connectors again, C on 0, D on 2 and E on 4 and my CD/DVD on 1 and found C back to 0 again. This was not done just by reboot, I shut down and did all checking. The BIOS and Registry all report the correct boot drive, yet when AHCI is enabled C is knocked out. It looks as if there are a lot of things that contribute to this annomily and it's gonna take a lot of people to figure it out.

Yes I'm still watching this and thanks for the information.

I'm watching as well. It's not life threatening but under my skin.

Whats really strange is the fact that after AHCI was initiated I checked the BIOS and C drive was still listed as first drive even though Windows reported it as disk 2. I have to apologize for not mentioning that before, I was doing a bunch of other things at the same time. Sorry bout that.

Hello mate, we all get busy and over-look things; mine seems to have settled down and been in the correct order in disk management the last couple times I've checked.

 

[treadhead194]

So what did you do to fix the problem?

Hello mate.


I just checked and they're all scrambled again. :shock:

I don't understand. I have had my stuff straight, other than using AHCI, for about two days now. I have shutdown, restarted, all that stuff and everything is still the same C is still 0, I've even turned on my external drives and nothing has changed. There has to be an answer. I did notice on one of my external drives, Windows reported that "F" drive which is external was an "Active" partition, so I ran DISKPART-clean all and now its just a Primary partition, none of yor drives is being reported as "Active" other than C right?. I'm going to make a stab at this but do you have AHCI enabled? If so that cold be the problem. Now I know you're gonna say no way but, what happens if your 1tb drive is disconnected? I'll bet you've tried all that right? In all honesty, when C was 1, it booted just fine and I don't think it will make much difference if C is 1, it just matters if you have to re install or have to repair, then you just disconnect the other drives,which you shouldn't have to but you just might have to live with it. Man, what a bummer.

Hello again.


I don't ever have to reinstall / repair if I don't want to, I use created Paragon images if real issues occur, the clean install was a furtherance of working on sorting this same issue and it's something I was interested in.

Yes I have / had AHCI enabled before the install.

I still think the rationale put forward by Dwarf looks reasonable now

ASUS have it as one of their FAQs and don't seem to have a solution.

Apart from it being a nuisance what do you see as the main consequence?

It's just a big PI M ... :shock:

 

[treadhead194]

The only consequence I see is that, should you have to re install/fix Windows, you'll have to disconnect all other HD's to force C to position 0. As long as Windows boots ok and there is no problems with installed programs then I guess leave well enough alone. But that's not the solution. I'll keep looking till I find one.

I would always recommend this anyway.
I'm still try figure out what a big " PI M... " is.

 

[treadhead194]

I would never have known about this problem if I hadn't lost my MBR on C. I've never had a reason to check on C. Even running Vista, never had a problem re installing. Do you have any Idea as to how long this problem has been around?

 

[treadhead194]

When I was running Win 7 32bit and had to re install I never had a problem it's only when I started to run the 64bit is when I found this problem. Am I wrong? Has this been a problem in 32bit as well?
