My desktop computer used to be able to recognize my Passport drive. I've had to replace the CPU and Motherboard and reload XP, but now it is having trouble recognizing the drive. Can you help?

My problem was a totally simple one...the connection of the USB cord to the Passport drive just needed to be moved in and out a couple of times and then the computer recognized the drive again.

“To install, and Update Hardware, click to open “Computer” from the “Desktop”, check to see if there is a by the ("Name, Passport") or DVD-RW Drive (D :), for external different (E or F:).
I. Look in the “Device: Removable Storage area,” see if the device is present, if so? Do the following: to “setup” the ('player') for “Installation.”
II. Right click on "Passport," or how shown listed, (DVD) “Media Player” select (“Install”) follow all instructions thereafter.
III. If the area is (Blank?), “go to,” and 'click' on the "Start button" click all “Programs” scroll for a “Media Disk Player”, open, and do the (“same as above”) for the installation. *Note: “Do the same for “Setup” (above) “Install.”
"Once everything is finished; restart the computer" "Ratings the solution is appreciated, thanks ”
