text: is downloading digital camera software safe? i mean the kind that you have to install with the cord hooked up to the computer. but is it safe? i heard that if you put too much hardware on a computer that the computers hard drive will crash or something. completely safe as long as you get it from the manufacturer. dont get it from a website that you dont know.  no such thing as too much hardware. if you can physically attach something, it is supported. the only exception is if your power supply can handle the load. if you have a fairly new computer, you are fine. a camera usb interface is nothing!
