Computer no longer shows icon for this drive

I’ve had this drive(WD 3T 3.0 My Book) for about 8 months now and its getting nearly filled…so I bought another drive just like it and now my computer makes the sound of the old drive being disconnected and reconnected but will not show the Icon in desktop…but it does show the Icon for the new drive…I took it a step further and hooked the old drive up to my old XP computer and it shows the Icon for the drive on there but this computer only has 2.0 capibility…does anyone have a suggestion on what I’m doing wrong and an Idea on how to remedy the situation?

You’re in the wrong forum. This is for the Cloud NAS.

sounds like a name clash because you have two of the same drives. Connect one and rename the Drive to something else. Then plug in the other one.
