I have a Western Digital passport hard drive since 4 years ago.
Recently, when I plug the external drive to my laptop, first it is detected but after some time, it is automatically unplugged.
I can't find an error with any software like "lifeguard Diagnostic for Windows" because during the process with the software, the drive is unplugged.
I don't know why it is happening and I would like to know the cause of this behavior.
