I have a wd My Passport Elite 640gb and yesterday i bought a new one. Its the same but with usb-dock.
My first wd drive its set-upd correctly and shown in “My Computer”
But, when i plug-in the new one, i only see 2 (two) “CD Drive (I:) WD SmartWare” and “CD Drive (G:) WD SmartWare”
and 1 (one) My Passport.
At “Disk Management” i can see both of them, but one offline and i get a message that says :
“Offline (the disk is offline because it has a signature collision with another disk tha is online”
Keep in mind that i have already change the names of the disks.
My system is Windows 7 (64bit)
Any ideas of what is wrong or any tip ?
Edit : i found the solution from this post —>
