Explorer Does Not See New Drive That Was Recently Copied

Greetings,

I am running Ghost 14.0 on a Windows Vista computer.

I most recently used the "Copy My Hard Drive"  feature to copy my main hard drive to an an external 1 TB USB hard
drive.  At the time I did the copy operation,  the progress indicated "Successful Copy".  However,  whenever I use explorer to view the drive and its contents,  the drive is not showing up.

I can go to the "Manage Computer"  snap-in and the newly copied drive does show up there.  It is listed as "Disk 1" (Healthy, active partition)  Size says 465.76 GB.   Also listed in Disk 1 is another partition (unallocated).  Its size is  456.75 GB.

Can anyone tell me why my newly copied drive is not showing up in Explorer and what can I do to fix it?  Many thanks ahead of time!
