Re: How do you play Sims3 from an external hard drive.

an external usb storage device is going to be slower (much slower) then a storage device that is directly connected. You need free space on the system drive for the operating system to work correctly. I recommend 20% of the capacity of the system drive be free. The best way to get more storage is to purchase a larger storage device (hard drive) and image the old drive to the new drive then remove the old drive and install the larger drive. Imaging only works with like devices (sata to sata, pata to pata, etc). There are shareware programs that will do this. I use Norton Ghost only because I bought it a long time ago and it works. With Seagate now shipping 8tb drives there is no excuse to run out of storage. Running programs from an external usb drive can be troublesome. Usb drives are good for mass storage like for music, movies, pictures, etc but not to execute from. The trouble with usb drives is that the drive letter can get reassigned and that usually stops the program from working correctly. Like the startup icon - that is a fancy short cut to the program executable and if the drive is re assigned the program will not be found (just one example). There are other ways (nas box?) but none are as good as using a bigger system drive.
