A connection to the TuneUp Drive Defrag service could not be established
Although the start type for the TuneUp Drive Defrag service is automatically set in Windows service management, the error message "The connection to the TuneUp Drive Defrag service could not be established. Please ensure that this service is available." appears when starting TuneUp Drive Defrag.
The problem is caused by a driver for external storage devices. This device is blocking the system longer than TuneUp Drive Defrag waits for the response from the service.
Manually start the TuneUp Defrag service. Wait a moment and then start TuneUp Drive Defrag.
