Question: I have a Windows 7 x64 machine, which has 4 drives in it. ?One of the drives disappears when the computer resumes from sleep. ?It is consistently the same drive. ?It disappears from my computer, and if I go to the disk management console. ?If I reboot, then it reappears. ?Any ideas what might cause this and how I might fix it?

Edit 2:

Some more background. ?This machine used to have XP on it and I had no issues then, all drives worked ok, and machine could sleep/wake with no problems. ?This issue started when I upgraded to Windows7 x64, and only affects one drive… ?Sometimes if it only sleeps for a little while the drive is still there, but if it sleeps for 20 mins+ then it always disappears

Edit:

Its a SATA drive, connected to the via onboard controller.

Answer: Been seeing this with a number of drives – 1TB satas – when resuming for s3 sleep.

Check to see if your drive supports s3 sleep mode:Please first check if your secondary drive support S3 in Windows 7:

Step 1:

  • Click the Start button, then in the “Start Search” box, type CMD but DO NOT press Enter yet.
  • In the list above, under “Programs” right-click on CMD that appears above and choose “Run as Administrator” and click “Continue”.
  • In the open window, type the following command and press Enter:
  • Powercfg /devicequery s3_supported

    Step 2: Disable write caching on the secondary drive

  • Click the Start button, then in the “Start Search” box, type DEVMGMT.MSC but DO NOT press Enter yet.
  • Right click “Disk drivers/your secondary drive” ?and choose properties.
  • In Policies tab, uncheck the option “Enable write caching on the device”.
  • Some have fixed this by installing the Intel Matrix storage drivers

    Others by forcing the drive from AHCI to IDE mode (bios setting)
