I received an external drive with 500GB. If I copy and paste everything on my C drive related to FS9 onto that and then delete it off my C drive will FS run normally only better or do I need to reinstall fs9, radar contact, PMDG 737, FS Passengers etc? I would like to copy and paste everything on my C drive onto the external drive and then delete it off the C drive but I imagine that might do bad things to the computer.I would appreciate any advise you could give me.Thanks,Chris Porter

Leave it where it is. Bus speeds could hamper access to the game not to mention possible decreased lifespan of your drive. Mike S.

I ran FS9 off an external drive for a while and the loading times will drive you insane. If you want to move stuff, transfer over your pictures and documents.

Hey Chris, My two cents. First of all, you would want to reinstall everything to that other drive. Cutting it and pasting it to another location will most likely cause tons of issues, unless you're ready to fix a boat load of broken registry links that can't find it.As others mentioned the external drive is a bad idea. I am guessing it is a USB 2.0 drive? If it were a SCSI or SATA external then depending on the motherboard it would be the same as running off another internal drive which would be fine.That leads me to my suggestion. Running FSX on it's own drive and away from your OS drive is better in a few ways and nothing negative about it, but as mentioned, not for USB or IDE externals.I currently have two western digital Velociraptors and FSX along with all my addons on one drive (D:) and the OS of course on C:. I also have a USB drive that I keep a second backup of all my programs, registration keys, etc... and it has come in very handy. I suggest using that drive for something along those lines.

Thanks for the advice all. That's what I needed to know. I'll go ahead and use the drive as a backup of everything on my computer and I will put other misc stuff on my C drive onto it as well. Too bad, was looking forward to flying on that drive--speed up/maximize flight sim settings.Thanks,Chris
