Will WD Passport Work With Win 7 ?

I have a Western Digital Passport #WDME1600TE (refurbished), it's drive size is 160GB, (149GB usable), at least that's what it showed in XP Pro. I currently have a XP Pro backup on it that I don't even have the laptop for anymore. I never really understood the way the thing worked. You plugged it in, logged on like you would a PC, then you could either use it the way it was (even on another's computer), or you could "sync" at any time.

I did "sync" my deceased laptop on it, but not all files were copied. I could visually see which files were and were not being copied. Fortunately, I never had to use the backup that was created on it.

Is there other software that I could install on this external drive that would make it simple to use. All I want to do is create a backup, not carry it around and use it on everyone else's computer. And I want ALL of my files to be copied. I hope that this post is understandable and that someone knows what I'm talking about.
