My laptop Lonovo T400 is running Windows 7 Home Premium with all updates from Microsoft. My WD external drive is My Passport Essential WDBAAA3200ABK (320 GB). I have updated the firmware (to version 2.019-184.108.40.206) and WD Smartware (to version 220.127.116.11).
WD Smartware worked well only for the first time after hardware and software updating. Yet, it did not work properly after I restarted my laptop. WD Quickview icon is still on the task bar; WD Smartware window appears on the screen but it gauges neither drives (C, D and E) on my laptop or the WD external drive.
What is the solution to the problem?
