How to remove "WD Unlocker"?

Is it a “WD Unlocker” VCD or a “WD Smartware” VCD?

The Unlocker VCD remains hidden unless you set a password, and hides itself again when you remove a password, but it cannot be removed from the drive.

If the school PC’s won’t allow the Unlocker application to run, all you can do is remove the password from the drive.

WD can’t force the school to install the Unlocker application on their computers.

If it’s a Smartware VCD, then if you install the firmware patch to hide the VCD, it should stay hidden for all devices the drive is attached to.  That’s the way it works for me… the hidden Smartware VCD doesn’t show up on this PC, doesn’t show up when plugged into the Server, doesn’t show up when plugged into Mrs. RG’s PC, doesn’t show up when plugged into the WDTV, doesn’t show up when plugged into the WDTV Live.

It seems much more likely that it’s the SES driver of which the school is blocking the installation.  If you don’t have a password set, you should just be able to skip the SES driver.  If you do have a password set, you won’t be able to unlock the drive without installing the SES driver – all you’d be able to do is remove the password from the drive at home and try again.
