I was trying to update the VCD partition with “WD SmartWare Virtual CD Manager for Windows Web Release-v1.0.8.3.exe”
That partition was once shown. However after updating with WD Software Upgrader (seems to be). The VCD partition was disappeared. Not shown under Win7’s Disk Management.
Drive: WDBACX7500ABK (Firmware already: 1.0.8.6)
