My second external drive isn't detected in
Windows
Sometimes only one of two external (ie, GoFlex, Backup Plus) drives mounts with a drive letter
when connected to Windows. This article explains.
Sometimes only one of two external (ie, GoFlex, Backup Plus) drives mounts with a drive letter
when connected to Windows.
This is caused if two drives have the same drive signature, which can occur when drives are
setup in a mass production environment or when they are cloned.
The issue can be quickly fixed by forcing the drive on-line. To force a drive online in Windows:
1.
Press Windows key (
) + R.
2.
In the run box type diskmgmt.msc
3.
On the right, scroll down so you can see your external drives.
4.
You will notice that the 1st external drive is
Online
.
5.
You will notice that the other external drive is
Offline
.
6.
Right-click on
Offline
(in the grey area of the box) and choose
Online
from the menu.
The drive should show in Computer (Window Explorer) in a few seconds.
