Lately, there has been a lot of talk about backup copies, media to perform them, and the like. In many of such postings, I have detected a kind of false security in partitions and their magic.
Do not mistake what I mean. It is intelligent to partition, it is very intelligent to keep all your work files in a partition that is NOT C:. That way, whenever a failure of the OS occurs, you are safe to format, reinstall, etc, your OS in C: leaving your works files unscathed.
Nevertheless, OS failure is just a "kind" failure that only affects the drive where it was installed (C: by default).
Unfortunately, computers have to rely on electricity, which brings along overvoltages, undervoltages, peaks, sags... You name it! It's there.
There are a couple of items that are designed to fight that. One is optional (a UPS), the other one is standard equipment, your power supply.
Initially, power supplies were designed to stop all electrical activity once they were hit with an overvoltage, for example. In truth, before they die, they actually wipe out the largest amount of components, specially the motherboard, the processor, and the HDDs.
Your contents are still within the HDDs, but the file allocation table may be damaged and the HDD will be detected as damaged or empty or without any format, hence rendering it useless (it can be worked out, but that's not the point of this post).
So, please, make sure ANY backup is done to external media, whichever, and do not simply rely on another partition or a second HDD to place it there.
I have lost 3 power supplies in the last 6 years. The last one died about 12 days ago. Both my HDDs were rendered useless, although I could end up retrieving all the contents in my main HDD. The other one is sitting in one of my drawers, in case I have some time to play with it a little bit more.
