When I turn on my computer it makes a mild screeching sound; which subsides once it's up to speed. I have also noticed that, sometimes, there is a kind of cyclic whirring sound that coming from my computer. It's beginning to feel like CRASH.
This is a two part question.
1. Should I consider replacing the HDD with an SSD? Are they less likely to wear out or crash?
2. What should I do to protect my data; before I take it in and leave it with strangers?
I know I can move all my files from My Documents; that's easy, but what about the data in "appdate"; where, for example, my Outlook data files, reside, and what about those other, out of the way, places? I'm even wondering how really secure my RoboForm data files from the prying of a trained technician.
