Running FS from a portable HD?

[Rob D]

Don't know if anyone has any experience with this, but...

I bought a 120 gig USB powered portable HD, and was hoping to run FS off it while I am on the road (which is every week for work). However, I can't seem to get it to run. I keep getting CTDs and lockups and such. Is it possible to get this to work on my laptop? It ran fine on the laptop a couple years ago, but it was on the main HD then. I have a shootload of scenery and AI now, and the total space it needs is almost 80 gig (the laptop has a 60 gig HD).

Any suggestions?

Thanks in advance!
