Windows 7: One of my hard drives wont wake from Hybrid sleep.

10 May 2011   #1

Win 7 Ultimate 64-bit
One of my hard drives wont wake from Hybrid sleep.

I have 4 Internal HDDs installed, 3 are SATA and 1 IDE, Whenever I wake my PC from a hybrid sleep the IDE drive no longer responds (slave drive) It causes explorer to freeze for awhile as it tries to access and the HD light stays lit until I reboot the PC.

Also Im unable to shutdown properly or reboot when this happens, I have to do a hard reset or hold the power button. (attempting to do a normal restart / shutdown always gets stuck at "logging off").

I never use to have this problem before, it seems to of started after I enabled Intel AHCI in my bios recently, but I didnt think this would effect an IDE drive? The drive works fine before the PC goes to sleep and no SMART errors are reported in HD Tune etc.

Any ideas appreciated.

If you used the intel controller to set it to AHCI mode - did you install this driver from the gigaybyte site it will update the AHCI driver and should provide correct functionality- Intel SATA RAID Driver - - GIGABYTE - Motherboard - Socket 1366 - GA-EX58-UD3R (rev. 1.6) i think its the latest version or equivalent version of the Intel Rapid Storage driver which is needed even when you dont have raid enabled. Note Im not 100% sure here as i have no gigabyte board and i cant unpack the driver to check it.

You could also update to the latest driver for your video card - long shot fix.

Otherwise Switch back to ide mode - AHCI is only usefull for hot swapping hard drives - if you have no need there is no speed difference as most modern hard drives have this enabled automatically. W7 should find the original driver upon rebooting if you just reset from AHCI to IDE mode in the bios.

If you used the microsoft fix, to be sure of success, follow this path in the registry : HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci - then right click start - modify and change from 0 to 3 - then go to bios and reset back to IDE mode and reboot.

I installed the Intel SATA Raid driver from Gigabytes website but the problem still persists, Video card has latest driver installed, Enabling AHCI gave a slight boost in performance according to HD Tune & Passmark's Disk Mark but nothing to significant, I may switch back to IDE mode or just remove the IDE hard drive from the PC altogether.

I didnt use any fixes to enable ahci instead I moved the boot drive to a gigabyte sata port and then enabled Intel ahci in bios, booted win7 (which detected and installed the Intel achi driver), then shutdown and moved boot drive back to Intel sata port.

but speaking of fixes I *did* install this hotfix after installing Win7 service pack 1 because my PC wouldnt wake up from sleep properly (it was shutting down entirely instead of sleeping) the hotfix worked and didnt have any issues with drives waking up etc. everything was normal until I enabled AHCI, I'm curious if there's a conflict between the hotfix & enabling ahci.
