No, it is not valid, and it is not true. |

Data corruption on-disk does not by and large (unless you are very |
20 |
unlucky) corrupt file systems. It corrupts files. |

Secondly, by and large, most people have all the files they really care |
23 |
about on one partition, called DATA or similar. Everything else except |
24 |
your data can usually be reconstructed, especially the OS itself. You |
25 |
probably store all that data in one volume simply because it makes |
26 |
logical sense to do so. Data is read and written far more than anything |
27 |
else on your disk so if you are unlucky enough to suffer volume |
28 |
corruption it's likely to be on a) the biggest volume and b) the busiest |
29 |
volume. In both cases it is your data, meaning your data is what is |
30 |
exposed to risk and everything else not so much. |

Yes, this is a real factor you mention. It is detectable and |
33 |
measureable. It's also minute and statistically irrelevant if you |
34 |
haven't dealt with environmental factors that cause data damage (dodgy |
35 |
ram, cables, psus, over-temps, brownouts). If those things happen, and |
36 |
they WILL happen, you are 10-20 times at least more likely to lose your |
37 |
data than anything else, no matter how you partitioned the disk. |
