My windows 7 x64 PC/server worked fine until I installed a brand new seagate SATA hard disk (2 TB). My first disk was a IDE Maxtor (250 GB). I tried to use it as a secondary drive leaving the maxtor as primary and, when I put the computer in sleep state, on wake-up the SATA disk is not recognized anymore until next reboot. Now I'm trying to set it as primary disk (I copied the old HD contents with HD clone), when the computer goes in sleep state, on wake up it doesn't see the disc thus causing my system to crash.
I tried the following:
- BIOS update (Asus M2V motherboard) but the situation worsened as the system didn't wake up from the sleep (with both my HD's)
- Reinstalling the drivers
- Bios changes
- Microsoft Hotfix KB977178 that seemed to address exactly my problem but gave me "The update is not applicable to your computer" message.
- Disabling hybrid sleep but no results.
I also tried all the suggestions from this question Why doesn't Windows 7 wake up from sleep?. Still no results.
