Troubleshoot:After installing a second WD 1TB My Book drive, Windows Explorer does not see the new drive.

After installing a second WD 1TB My Book drive, Windows Explorer does not see the new drive.

Original Title: Signature Collision?
I am having difficulty installing a second external drive.
I'm using Windows 7 Ultimate RC.
There was one WD 1TB My Book drive already installed - healthy and functioning fine.
The problem occured after installing a second WD 1TB My Book drive.
I followed
all instructions, pluuging the drive into a USB Hub.
Windows discovered the drive, installed the drivers and reported the new drive ready for use.

Windows Explorer does not see the new drive.
Devices and Printers shows 2 external WD drives.
Disk managemant also shows 2 drives but the second drive is offline because of a "Signature Collision".

Each drive works fine if it is the only drive plugged in.
"Eject My Book" does not work because a program (or more) is using the drive in the background (Windows or Norton).

I've installed the latest firmware and am still having this problem.
I've been emailing WD with this problem and they have run out of ideas.

Can anyone help?

This is horrible advise unless you know the drive is empty.  Use the Windows Diskpart command.  Select the Offline Disk.  Enter the command Online Disk.  Diskpart is much more powerful than the Disk Management.  I had this problem and Diskpart brought the
drive online with NO issues where Disk Manager continued reporting a Signature Collision.
Sorry to sound harsh but to format the disk?  I would think removing the disk and doing an Import Foreign Media would probably work allowing you to then place the disk bakc into the original computer.  If you still get Signature Collision...use the above
it works fine.
My Signature collision was cause by Acronis Disk Suite...HORRIBLE software if you have Windows 7....have had noting but problems...seems any disk it touches corrupts the MBR and Signaure area.
I had this exact same problem and I used this answer to help me.
In my case I left a second hard disk inside my drive when I rebuilt my primary disk with Windows 7.
The second drive wouldn't be seen in Windows Explorer, Disk Management showed me the disk
was present but "Offline due to Signature Collision" - there wasn't an option to make the disk go online via right click either.
I took the second disk to work, put it into a caddy and moved all the information off of it and then ran a full format.
Came back home and plugged it in but no joy.
I couldn't right click and make the disk go "online" again through Disk Management as before.
I ran across this answer through google and as a thank you will write up the process.
If you have the same problem of Signature Collision try to go to "Manage Computer" and then "Disk Management", find your drive and then right click to make it go "online".
If it wont work then go to a command prompt and type the following in " ", hit return
to move through:
"Disk Part"

(this brings up a separate window in Win 7)
"List Disk"
(This will show you which disks can by physically seen, offline and online)
"select disk X"
(Where x is the number of the disk you want to make online)
"online disk"
(This should bring you a message saying your disk is now online)
This takes you back to windows and you should now see your disk through Windows Explorer.
Thanks for the start KevinEBrown!!

Manually editing the Windows registry

Caution: Unless you an advanced PC user, please do not edit the Windows registry manually.

Because of this risk, we highly recommend using a trusted registry cleaner such as SmartPCFixer Using a registry cleaner automates the process of finding invalid registry entries, missing file references (like the one causing your MACHINE_CHECK_EXCEPTION error), and broken links within the registry. A backup is automatically created before each scan, with the ability to undo any changes in a single click, protecting you against the possibility of PC damage. The best part is that repairing registry errors can also dramatically improve system speed and performance.

  • Click the Start button.
  • Type "command" in the search box... DO NOT hit ENTER yet!
  • While holding CTRL-Shift on your keyboard, hit ENTER.
  • You will be prompted with a permission dialog box.
  • Click Yes.
  • A black box will open with a blinking cursor.
  • Type "regedit" and hit ENTER.
  • In the Registry Editor, select the Error 0x9C-related key (eg. Windows Operating System) you want to back up.
  • From the File menu, choose Export.
  • In the Save In list, select the folder where you want to save the Windows Operating System backup key.
  • In the File Name box, type a name for your backup file, such as "Windows Operating System Backup".
  • In the Export Range box, be sure that "Selected branch" is selected.
  • Click Save.
  • The file is then saved with a .reg file extension.
  • You now have a backup of your MACHINE_CHECK_EXCEPTION-related registry entry.

The next steps in manually editing your registry will not be discussed in this article due to the high risk of damaging your system. If you would like to learn more about manual registry editing, please see the links below.
