I have a 4TB WD40EZRX drive installed into my Windows 7 Pro SP1 64bit computer. Windows power settings are set to spin down the drives after 15 minutes. Sometimes, after the drives have been spun down the 4TB WD drive never comes back when Windows spin the drives back up again. The drive is not detected at all in My Computer, Disk Management or the Device Manager.
If I restart the computer, the drive is still not detected. If I power the computer off and then turn it on the drive works like nothing happened to it.
I’ve tried different SATA ports, different SATA cable and a different SATA controller with no change in this issue.
Are there issues with these drives being suspended? Is there any other workaround besides disabling the sleep setting in Windows power management?
