Enclosure for External Hard Drive not Working!

by sugarbear246 - 4/24/12 4:17 PM

I have a Dell Inspiron 531 Desktop that run XP Pro 64bit. I took my Old Hard Drive from my now Dead, Old Desktop and Enclosed it in a "Rocketfish" Hard Drive Enclosure.
MY "Safely Remove Hardware" Icon in my "TaskBar" shows a Drive that Can be Safely Removed....(THAT HAS NO DRIVE LETTER)? My Computer (SEES THE DRIVE BUT I CAN'T ACCESS IT)?
Am I missing something here, or I am correct in assuming this Enclosure is "Plug and Play"?
I need help!
Thanks;
