Deleted the software My Passport 2 TB

I accidentally deleted all the software from My Passport to my computer desktop and now the My Passport is not recognized by any computer. It also wont allow any of my computers to start while attached (vista and XP).  I have all the software on my desktop I just can’t see the drive to load it back on. Is there anything I can do to get the software back on the drive?

I was able to format and map a new drive letter through disk management. All is good.
