you will loose any pictures, songs, software, anything that you haven't backed up that is currently on your hard drive. When you switch it out you will likely have to install an operating system, unless your using one out of another computer that already has the basics on it. Most likely it will be fine, if you encounter problems, switch it back.
no
Opening a hard drive can mess it up, if you have no clue what your doing.
yes .. if the car is in drive and u put it in reverse.... bye bye gears
I am pretty sure it does not, as it only uses the hard drive, it does not mess with the MotherBoard, as far as I have seen.
No, not usually.
It depends on what kind of laptop you have, and what kind of flight simulator.
nope. you can install one OS on the first drive. then if it's XP/vista choose manage and disk management to make the second drive active...it's about it man. (note it's a laptop so you might not have to mess with the jumpers for master and slave like you would on an older IDE system, if it's a newer laptop you'd have to make sure that they come up in the laptop BIOS tho.) good luck man, Fitzy111
Probably so users don't try to store anything on the drive; that would mess it up if you ever needed to boot to the recovery partition of your hard drive
Contamination or switching tests accidentally.
If you hold it down until it turns off, yes it could mess up your laptop. BUT if you press it once and wait till it turns off, it will be fine
Depending on the speed you are going, yes it could really kill your transmission and your engine! But don't be afraid, your car is not suppose to allow your transmission to downshit if your going to fast for that gear.
Roblox is simply a program, and is very unlikely to "mess up" your laptop. If by this question you mean does roblox contain viruses, the answer to that is no as well. Roblox has been tested by several anti-virus sites and was found as clean.
