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

19 Data corruption on-disk does not by and large (unless you are very
20 unlucky) corrupt file systems. It corrupts files.
21
22 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.
31
32 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.
