I found that turning off "Hybrid Sleep" solved spinning up HDDs before sleep issue with RST driver.
But i wonder, why default "ahci 1.0 serial ATA" driver have not this issue with "Hybrid Sleep" enabled?

Hello

I have a big issue and I hope you can help me... I have and old P5QL PRO, P43 chipset on a W7 32bits, with a 250Gb SSD, 320Gb SATA and 2TB SATA, and I had added a new 4TB internal HDD but it only detected 1.64TB... even using GPT initialization.

After many hours of googling for solutions, I came across your forum and I installed your recommended intel drivers "Intel RST AHCI/RAID Drivers & Software Set v11.2.0.1006".. then on reboot, first I had some minor problems.. computer didn't boot because changes in the BIOS that had changed from ACHI to IDE, I changed it back to ACHI and booted ok.

Then when intel drivers installation finished, the new 4TB HDD was detected with its full size, so I was very happy...but, now when I access the previous 2TB HDD Sata comes my big issue: I can see the files, but I can't access them anymore, it's like the drive became corrupt all of a sudden.. also in some reboots, the disk is not detected, or detected as raw.. I have run some recovery software with no success

Can you tell me why might this be happening and if there is something I can do to recover the access to this drive and its files??

Thank you very much

Thank you for your quick reply

I answer your questions:

Questions:
1. Which storage driver did you use before you installed the Intel RST driver v11.2.0.1006?
The one which came by default with the W7 installation and the Asus update.. it was rather old, I think it was this version V8.9.0.1023

2. Are all your storage devices (SSDs and HDDs) connected to SATA ports, which are managed by the Intel SATA Controller?
Yes, all the storage devices are connected to the mainboard SATA ports

3. What does the Disk Management show regarding your 2TB HDD?
It's listed as active and in the Intel console appears as active and ok.. the windows file explorer sees the disk and I can access the folders, but when I try to open / copy any file it shows an access error.. also an error regarding the recycle bin. And sometimes, when I boot the computer the disk does not show at all and it appears a message "format disk to use" and in disk management appears as RAW. With some recovery tools it says there are damaged sectors, but the disk was in perfect condition before installing the driver.

4. Why did you install the complete Intel RST Drivers & Software Set (the Software is not really required unless you have created a RAID array)?
Maybe because I am not an expert (sorry) and I was desperately looking for solutions before having to return / replace the new 4TB HDD.. and I thought that updating the Intel drivers might do the trick.. it really did for the 4TB, but with the collateral damage to the previous 2TB HDD..maybe I should have unplugged this HDD before updating the drivers??

5. What happens, when you swith to the generic MS AHCI driver?
This I can't tell you.. I don't know how to do that and I'm afraid that if I do and downgrade, could it affect the other drives??

--
Thanks again for your support, the drivers really managed to solve the 4TB issue.. I don't know why in the process the 2TB HDD was damaged (the other 250 gb SSD and 320gb HDD are fine)

Any help or hint would be extremely appreciated to avoid losing the large amount of files I have in the 2TB HDD :(( and maybe to prevent this from happening to other people in similar situations

Regards

Thanks!!

I followed your suggestion of unplugging the other HDD's and then boot with only the 2TB HDD attached and then it was recognized... afterwards, I shutdown PC, plugged the other drives, then on Windows started automatic controller installation and even though at first there seemed to be a problem again, after rebooting and checking the cables a few times, finally I managed to boot the PC successfully: all drives recognized and also with really fast transfer speed between them.. maybe I must wait a little longer to ensure the stability of the system, but after a few hours and reboots it seems OK and I'm very happy to finally have managed to install the new drive and give a new life to this PC

So I thank you very much for your personalized support and the whole information you provide in this forum.. without you I think I would have ended either formatting the 2TB drive or returning the new 4TB

The update from 16.7.0.1009 to 16.7.7.1023 does not work for me, at the install it ask me if I want to update but does not show version numbers, after the installation and reboot its still the old version on my system.

I always do the same like on every update, run the SetupRST.exe as Admin and update the software.

I have a ASUS Prime Z270-A running in AHCI mode... wait I see at the hardware manager the driver updated to 16.7.7.1023 (03.10.2018) but the software shows 16.7.0.1009

My hardware ID:
PCI\VEN_8086&DEV_A282&SUBSYS_872F1043&REV_00
PCI\VEN_8086&DEV_A282&SUBSYS_872F1043
PCI\VEN_8086&DEV_A282&CC_010601
PCI\VEN_8086&DEV_A282&CC_0106

Thank you Pacman for the updated version, the version 16.7.9.1027 works without problems. I install it and it updated the driver and software like it should and did always before.
driver version 16.7.9.1027 (15.10.2018) - and software version 16.7.9.1027
The "Intel RST Drivers & Software Set v16.7.7.1023 WHQL dated 10/16/2018" have a issue, it only updates the driver but not the software.

@Fernando I never did that before updating to a new version and there was never a problem with the update process. I made this so many times now. The IRST ask at installation, did you want to update from version xx to version xx and did everything by itself.

For those of us who like it raw (just drivers, not install software), are there some registry entires to enable Performance modes that RST installers have? I know that write caching can be enabled/disabled within Device Manager, but I am unsure about the "performance gear". BTW, does OROM/Driver match recommendation remain? For example, with OROM 16.7.0, it used to be that drivers 16.7.0 would work best, but these days we have OROM 16.7.0 with driver 16.7.9. I think OROM 17.0 just came out on Station Drivers.
