Of interest is the fifth byte with the value 0x30 – or 00110000 in bits. Then run the following command (keep in mind to adjust the drive letter to match it with your WD hard disk), which reads out mode page 0x20 of your disk.
#VIRTUAL CD MANAGER WESTERN DIGITAL INSTALL#
Under Debian (and its derivatives) you can install it with $ sudo apt-get install sdparm One of the page is page 0x20, which contains the information necessary to enable or disable the virtual cd.įirst you need to install sdparm. Western Digital uses undocumented, vendor-unique SCSI mode pages.
#VIRTUAL CD MANAGER WESTERN DIGITAL UPDATE#
See the virtual cd-rom at /dev/sr0? Also note that the hard disk appears as /dev/sdc on my system, so you will have to update the following commands accordingly if your disk has a different system letter.

No results with Google either, so I had to dig a little further. According to Western Digital, there is no known way under Linux to disable (and hide) the “Virtual CD” (VCD) partition that can often be found on their external hard disks (such as the popular My Passport series).
