My computer came with one hard drive, but I added a second drive because the primary is nearly full. I use the second HD for my videos for the most part. My operating system (Windows XP Hom Edition) and and everything else is on the original (primary) “C” drive. Today I downloaded an updated driver for my graphics card. Instead of downloading it to my C drive, I "saved" it to my large slave (jumper is set to CS per WD) drive. I have not attempted to install this updated driver yet because I started thinking maybe I should have downloaded it to my primary C drive. I began to wonder if the driver will install properly from drive F, or if the hardware (graphics card) will operate properly if the updated driver is installed this way. Does it really matter which hard drive "updates" or other "software"are downloaded to before they're installed? I don't understand the relationship between two different hard drives, the hardware (in this case the graphics card), and the software (updated driver in this case). Could someone explain how the software gets installed in the hardware? Or does it really get installed on the hardware? As you can see, I'm a novice and need your help to learn this process. When I install the updated driver, will the install work just good as if it had been downloaded to the C drive? Your guidance would be greatly appreciated.
