My secondary hard drive works fine until the computer enters sleep mode. When I return from sleep mode everything works, except for that hard drive. I have to restart my computer to get it back.



I've never had a problem like this before so I don't know what to look for. Can anyone help? I've checked the BIOS and drivers and they're all current.



Oh, by the way it's a SATA drive.



Also, I don't know if it's related, but I often get delayed write failure messages (though they don't seem to affect anything).
