I tried to set up my drive and in the process my dive has disappeared. I can get my cd but not the external drive icon . I work on a macbook pro &nbsp;with time machine. I never got the message acknowledging time machine when I was setting up and now I can no longer do anything. I uninstalled and still have no icon.

If you are planning to use the WD MyBook for Time Machine.

I would suggest you to not install the WD Smartware software.

If you have already installed the WD Smartware, Please uninstall it.

Here is what you need to do:

a. Unplug all power cable and firewire cable from the WD external drive.

b. Restart the MacBook Pro computer. Wait for all icons to show up before move on.

c. Re-plug the firewire cable to the WD external drive.

d. Re-plug the power cable to the WD external drive.

&nbsp;&nbsp;&nbsp;&nbsp; wait a few minute for the drive to be recognized.

&nbsp;&nbsp;&nbsp; Time Machine pops up may show up.

&nbsp;&nbsp;&nbsp;&nbsp; if yes, go ahead say yes to Time machine.

&nbsp;&nbsp;&nbsp; If Time machine is not showing up. You need to re-format the WD external l drive.

&nbsp;&nbsp;&nbsp; Keep the WD external drive plug in.

&nbsp;&nbsp;&nbsp; Go to Go on the apple menu.

&nbsp;&nbsp;&nbsp; Go down to the Utilities.&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;Select&nbsp; Disk Utility.

&nbsp;&nbsp;&nbsp; Highlight WD MyBook drive

&nbsp;&nbsp;&nbsp; Click on Partition.

&nbsp;&nbsp;&nbsp; Under Volume Scheme click on Current then select 1 Partition.

&nbsp;&nbsp;&nbsp; Click on Options and select GUID Partition Table, then OK to accept it.

&nbsp;&nbsp;&nbsp; Click on Apply.

&nbsp;&nbsp;&nbsp; Click on Partition.

&nbsp;&nbsp;&nbsp;&nbsp; When it finish, unplug the WD external drive and re-plug it.

&nbsp;&nbsp;&nbsp; The Time machine show pops up and you can use it.
