I've used Dataram RAMdisk V3.5.130RC9, worked fine mostly, but i've had it crash 2 times. The first was when i tried to unistall it and the driver wouldn't shut down, but i managed to remove it from a device drivers list. The second time was some error that occured after a couple of months where the program that changed settings for the driver wouldn't open and gave some error, but the RAMdisk worked perfectly anyway. I did a full uninstall and re-install and it has worked fine since.

I see RC10 has been released, so maybe they have fixed those two buggs now. They only occured when i tried to change things after the RAMdisk was in place anyway, and didn't crash the system.
