A minor delay occurs when Windows Vista or Windows Server 2008 resumes from sleep if the hard disk is attached to a secondary ATA port
Consider the following scenario:
- You have a computer that runs Windows Vista or Windows Server 2008.
- The computer has multiple SATA ports, and the disk controller is configured in the BIOS to operate in IDE mode.
- You have a hard disk attached to a SATA port that is exposed as the device 1 (secondary) port.
- There is no hard disk attached to the device 0 (primary) port of the same channel as the hard drive.
In this scenario, you may experience a delay of several seconds when the computer resumes from sleep. This behavior causes the computer to fail Windows Logo Program requirements for standby resume times.
