Vista doesn't recognize remote hard drive?

I have a Wolverine 7000 remote hard drive that previously worked just fine
on my XP machine.

It is listed as a drive on the listing on my Dell Inspiron 1525 special
edition notebook computer. I am running Windows Vista home edition (32). I
checked for a driver update and am told, by the computer, that I have the
latest updated driver for the machine.

However, when I plug the drive in...my computer does not "see" it in the
"My computer" section. I then fully charged The Wolverine HD and retried.,
to no avail.

Any and all help appreciated. thanks Rich
