Hard drive disappears when the computer resumes from sleep

Hard drive disappears when the computer resumes from sleep 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?

I wasn't able to solve this, but I was able to work around it. I plugged the drive into a raid card instead of being on the mobo (had to disable my raid to do this though) and plugged the drive that was in the raid into the mobo. now all drives work ok and don't disappear when it sleeps... weird.

try the drive with a another cable and/or on a different port and check whether the problem persists.

"To me, this sounds like the hard drive is simply slower at waking up / powering on than the others and your machine does not fully support hot-plugging.

If I was you, look in the BIOS for any option called ""Hard Drive delay"" or anything else with the word ""delay"" (or similar) on it and see if you can set it."
