Windows 7: Hard drive stops Windows 7 from sleeping

Hard drive stops Windows 7 from sleeping


I have found something odd today. Normally my computer goes into hybrid sleep mode just fine. But I have just added an oldish SATA hard drive to the system, and now it won't go into sleep mode.

After selecting Sleep, the screen fades to black then immediately returns to the "computer locked" screen.

The drive itself seems to work fine, and the problem goes away after disconnecting the SATA cable from it.

Anybody got any ideas for this one?

Might want to check the properties for that drive in Device Manager.
