What are the statistical chances of that one minor partition being the |
71 |
one that gets corrupted? Statistically the odds are very small. |
72 |
|
73 |
Think about it, if the minor partition is say 5% of the disk and if all |
74 |
other things are exactly equal, the odds are 1 in 20. |
75 |
|
76 |
Apart from inherent defects in the drive itself, the sectors that are |
77 |
more prone to failing are those that are read the most and to a larger |
78 |
extent those that are written the most. |
79 |
|
80 |
What is read the most? OS and Data |
81 |
What is written the most? Data |
82 |
What has by far the greatest likelihood of suffering fs corruption? Data |
83 |

I don't disagree with you. I'm disagreeing with cargo cult mentality |
93 |
that dividing a disk up into lots of smaller partitions somehow |
94 |
magically confers significant safety margins of some magical kind. Go |
95 |
read the OPs opening statement again, he's quoting a friend from 20 |
96 |
years ago and the statement consists entirely of woo-woo magic |

hand-wavey statements, the kind of shit I have to deal with every day |

Yes, drives fail. Yes, consumer drives are crap. With 3TB now being |
101 |
common place and prices plunging, we have 20G or so for OS and 2980GB |
102 |
full of data. That 20G is so small and immaterial in terms of risk we |
103 |
can just disregard it and assume the only thing that can be damaged is |
104 |
2980G of data. |
105 |
|
106 |
Solution: back up the whole damn lot properly and forget what we did 20 |
107 |
years ago. That was farting in a breeze, nowadays it's farting in a |
108 |
hurricane. |
