GPT Disks causing problem

post #1 of 10
Thread Starter 
Hello
Newbie to these forums here, but with loads of IT experience as a DBA/Unix sysadmin on corporate servers - so I know when there is a real problem as opposed to a 'furphy', well most of the time anyway.
I thought I was going crazy until I found someone on another forum with a very similar issue, same mb as mine, Asus P8P67 deluxe.

I acquired two WD 3 Tb disks so thought it would be a good idea to build a RAID-1 array via Intel RST 10.5 software/drivers (latest available for this board on the Asus site). Of course I used GPT for both disks, made a 3 Tb array - just data, NOT a boot drive. All seemed well. Computer crashed overnight, and my Intel SSD boot drive did not appear in the BIOS SATA listing. I blamed it on the Intel 10.5 software, so I reverted my SSD boot drive to a cold Acronis backup taken prior to the whole exercise. I reverted disk type to AHCI (NOT RAID) in the BIOS, and there was once again NO sign of the Intel RST software nor drivers in my system, all looked good. My two 3 Tb disks were now 'normal' basic disks, GPT and 3 Tb each.

Next morning - same thing, my PC had crashed and the BIOS did not recognise my SSD boot drive - again it was again not present in the SATA listing. The only possible explanation is the presence of the new GPT 3 Tb disks - I have since converted them to MBR (2 Tb each) and there is absolutely NO problem.

Can anyone please help me by having a guess as to what is happening here ? It seems that the mere presence of a GPT drive is somehow influencing some driver, or the UEFI BIOS, or both ... as mentioned above, I am not the only one who has observed this problem. But I am stumped, and would like some light on this issue before I proceed with any possible solutions (such as Windows8, modded BIOS, Intel RST version 12 ....)

What is your BIOS version? I had a problem similar to you in the sense that my SSD was not being detected and I just needed to update the BIOS and it solved the problem.

BIOS is the latest, 3602. OS is windows 7 64-bit.
The similarity to the other reported problem (on another forum) is that the two GPT 3 Tb drives were plugged into two SATA 6 Gb ports (Intel not Marvell..).

Disconnect your two HDDs for now and see if you can boot your computer. If you have already done this, let me know what happens.

I think we are headed down the wrong track here.
My PC BOOTS AND BEHAVES just fine with the two 3 Tb disks present and defined as MBR (of course only 2Tb per disk are then available).
it is only when they are turned into GPT disks that the problem occurs. Before introducing the two 3 Tb drives I never had a crash in two years, so that answers your question.

And the 'missing SSD boot drive' problem only happens on a warm reboot after the crashes that I mentioned - a cold boot then causes the SSD drive to re-appear, the 'missing' issue is not a permanent thing. My main issue is - why are the crashes happening when the only change made to the system is the presence of two GPT 3 Tb drives defined as basic disks (no RAID, no Intel RST) ?

And remember, the two drives causing the issue are just DATA drives, not boot/system drives.

I have just run into similar issue with failed RAID1 (mirror) on 2x 2TB WD Black drives over Intel controller and under win7 x64 SP1. that RAID volume is for storage only, boot drive is an SSD.
Issue happens only when I initialize the RAID in GPT mode then the whole Disk Manager hangs on or right before Formatting the volume. The first time I did it, it actually crashed with black screen.
Problem doesn't happen when I initialize the RAID volume in MBR mode, then it always runs normally.

I believe this a win7 x64 issue requiring some hotfix. haven't heard of such problems (maybe yet) in win8 x64...

EDIT:
forgot to mention, it happens on new business workstation, HP model Z220, chipset is C216 (Panther Point), CPU is 3770.

Thanks for that, I feel better knowing it's a genuine issue rather tham my own stupidity or a bad disk! Interesting that you get the problem with 2TB disks, I was convinced that it was my 3TB factor that was triggering this. What is now clear is that GPT under Win7 x64 is somehow causing this, it is the common factor in our two scenarios, remembering that I had problems with GPT even after banishing Intel RST from my system. If you do find details of a hotfix/patch, please let me know. I will try using GPT on the disks one more however, using the two 3Gb SATA ports (Intel) for these instead of the two Intel SATA 6 Gb ports.

yeah, I googled it and found a few more instances of the same problem (RAID+GPT) under win7 x64. seems pretty common unfortunately ...
I did run IRST drivers however (11.7) and that was though SATA2 ports ... oh and actually that was about 1TB drives (WD1002FAEX), sorry for stating it was 2TB earlier.

In case anyone is still interested, this problem seems to have been solved, at least on my machine. However I cannot say precisely what did the trick, it was a case of fiddling with a few things, now the problem (hopefully) has gone away (no crashes in 3 days). It is all to do with power management and C-states. Basically, disable all 'allow xxx to wake up your machine' (where XXX=LAN, mouse, USB etc), adjust your 'advance power management' for the 'high performance' plan and allow only the monitor activity to allow sleep state. Ironically after all of this I also issued "powercfg -h on" from a command window (found an article stating that this was critical).

I found all this by searching on an error string from the time of the crash (from the windows system log) - it is a known problem, even though the error itself is fairly generic. Microsoft has issued a couple of hot fixes in this area, but I did not judge them to be relevant for me so I have not applied them.

My previous post was on the right track, but a bit misleading. I think it is now sorted at last.

powercfg -h on turns ON hibernation, but now I have it set to OFF, which makes a lot more sense.
However the setting that really solved this issue is the one that prevents the disks going to sleep in the power management settings (well 1440 minutes actually, which implies 'almost never' in my case at least).
Previously it was set to 30 minutes - and the crash (or just the disappearance of the RAID volume in some cases) would always happen after a period of idle time. My RAID array would be still present and correct as far as the RAID management software was concerned, but Windows disk manager would see it as an empty volume (or just not see it at all).
