My book not detected after my passport connected

Portable Drives My Passport
1

Hello,

I have 2 WD external drives :

  1. My Book Premium Edition 500 GB
  2. My Passport 1 TB

On the computer A, My Book is no detected after connecting My Passport

On the computer B, My Book works perfectly. My Passport has never been connected

On the compouter C, I connect My Book, it works, I disconnect it. And then, I connect My Passport, it works, I disconnect It. And then, I connect My Book again, It’s no longer detected

I uninstalled the software WD Unlocker supplied with My Passport but It doesn’t resolve anything

What can I do to resolve this ?

I hope my english is not too bad

thanks for your help,

Philippe
