MyPassport - not recognized on my Vista Laptop

I have a Passport 320 external drive.  It works just fine when connected to my desktop machines (one Dell with Vista 32 and one HP with Vista 64).  When I connect the drive to my laptop (Toshiba with Vista 32) I can see the SmartWare partition as a CD.  But the main data partition is not recognized as a drive.  In the Disk Manager it shows up but with FileSystem as “RAW” (when I connect it to my Desktop Machine the FileSystem is “NTFS”).

I’ve seen lots of posts with similar problems but not a solution.  HELP!

Have you tried contacting technical support on that issue? You might need a power booster cable.
